Oakland Hills Country Club - Turfgrass Maintenance

Exposing Donald Ross

2012-01-24T15:08:00.004-05:00

The Donald Ross 'restoration" craze has in some instances been misguided. In one area Ross deserves credit: routing and use of available land forms.

We removed two maples ("weeds that got hard") to the right of number 12 green South mostly to improve turf conditions in a high traffic area.

But a bigger advantage is to further expose the ridge line that Ross used to route so many golf features over and across. This ridge line begins farther to the east on Lahser Road, continues across #6 and finishes on #15 green. Ross built the following features on that ridge, one of two major landforms on the South Course: #5 fairway, #7 tee, #6 green, #6 fairway, #14 fairway, #13 tee, #12 green, #16 tee and #15 green. Pretty awesome foresight without computer aided design (CAD).

Removing trees ("weeds that got hard") from these ridgelines allows us to see what this golf course was meant to be.

The piles of stump grindings can be seen on the right side of this photo.

2012-01-21T13:21:00.000-05:00

We came in today to make sure the greens are cleared before the warm temperatures, melting, rain and ice arrive over the next 4 days.

Greens look great, we should survive this event just fine. Thanks to the staff for giving up their Saturday.

Winter Drains

2012-01-20T10:41:00.000-05:00

Before shutdown in the fall, we check and open every surface drain and mark it with a flag. By removing the caps on small surface inlets we provide an easy channel for water to escape. The quicker we can remove surface water the smaller chance of ice buildup, and we have discussed the dangers of prolonged ice cover on turf.

Most of the South Course surface drains ultimately move water to either the pond on #16 or the pond on #7. All of this water exists the property through the creek on #5 out to Lahser Road.

In the spring, Copper Sulfate is added to some of the drains to reduce root encroachment from nearby trees. Or as Dr. Vargas calls them .... "weeds that got hard".

Winter Play on Greens

2012-01-11T12:12:00.000-05:00

The North Course is open for play all year, weather permitting. In the winter we rotate between playing temporary greens in the approaches and the regular greens. Traffic on completely frozen greens does cause damage but at an acceptable level so when temperatures are cold enough we will have pins in the regular greens.

However, the weather we are experiencing results in a freeze-thaw cycle, leaving the surface unfrozen above a frost layer below. If frozen greens thaw during the day, however, golfer traffic may cause shearing of the upper profile (the thawed layer) from the still frozen soil below, which could severely compromise turf health and future playability. As such, closing the greens on days when thawing is possible is recommended.

Direct wear injury, soil compaction and most importantly compromised playability are all a result of winter traffic on greens. Please follow the posted signs that will inform you if the temporary or regular greens are in play.

Course update, Friday January 6th

2012-01-06T10:49:00.001-05:00

The North Course is open to play on temp greens only.

Even with the moderate temperatures, there is a frost layer below the green surface. Traffic under these conditions is not advisable.

Thank you.

Tree Removals II

2012-01-05T15:08:00.000-05:00

Today we removed a Silver Maple from the back right of #1 green. This will allow approximately 3 hours of winter sun to help melt snow and ice from the more susceptible section of the green.

The following awesome photos are a perfect example of how trees and their shade patterns have a negative influence on healthy putting surfaces.

The large dark shadow is the tree trunk that has yet to be removed. The section of the green in full sun was - prior to today - in full shade from the tree canopy for the past 50 years. The left side of the photo shows the canopy shade from the remaining tree.

Tree Removals 2012

2012-01-04T12:41:00.001-05:00

In conjunction with our Aesthetic Plan, Tree Plan and Golf Course Improvement Plan, the Board of Directors and Green Committee have approved several tree removals on both courses. All of the trees scheduled for removal were recommended, reviewed and approved by Rees Jones.

Most of these trees are conifers that impede or detract from the playability of the golf course or are trees interfering with healthy turf. Many of the trees are also in very poor health. A total of 50 trees are scheduled to be removed, weather permitting. The ground must be frozen so the equipment does not damage the golf course.

I will be giving you more frequent updates through Twitter: @OHCCturf.

The Winged Rat

2012-01-02T12:13:00.003-05:00

Also known as a Canadian Goose. Nearly driven to extinction at the beginning of the 1900's, efforts at reestablishment have been so successful that the current population is thriving. So much so that airplane passengers to property owners are crying fowl.

Canada Geese love open lawns because they can easily digest grass and they afford wide open vistas for the geese to see predators. Unfortunately this includes airports and golf courses. It is estimated that just under 3 million geese are 'harvested' by hunters every year but these flying rats are so prolific that it has done nothing to dent the population numbers.

Control? There are a few things you can try, but geese are very difficult to control.

The most effective method for us has been harassment. Using an air horn or loud noise maker (like a propane canon at airports) to scare the geese away seems to work if done consistently. If nothing else, is does provide some enjoyment. We also use a 'coyote decoy' to scare the geese, but it too needs to be moved regularly so the geese don't catch on to what you're doing. You can check out http://www.pcsoutdoors.com/ for a selection of bird decoys. Or Gemplers has a nice selection too.

We are permitted to destroy nests when they appear in the spring. Nest destruction is a necessity if you don't want the geese to return year after year. Barriers like fencing and screening are marginally effective as are chemical repellents. It is important to use a variety of methods; together they may reduce your goose nuisance, but most likely won't eliminate it.

But as Choo Choo Love says at http://www.lovecanadageese.com/: "The lead goose is the conductor, his flock the orchestra. Together, they are a symphony of joy, a chorus for the ages."

So beautiful.

Monday, January 2nd

2012-01-02T10:11:00.000-05:00

Looks like the course came through the wind just fine. All the covers are intact and just a few limbs down.

Today we'll finish checking the golf course and start on winter refurbishing of equipment.

Course Update

2012-01-01T17:54:00.000-05:00

With tonight's high winds, it's possible we may lose a green cover or two. Certainly a few branches will fall.

When we get in Monday morning, we'll review both course and let you know the status.

I hope you had a great New Year!

Ice Layer

2011-12-28T13:59:00.000-05:00

During my walk of the South Course today I noticed a thin, airy layer of ice throughout the golf course. It's not very thick, breaks up easily and I believe will melt with the upcoming forecast.

The layer is thicker on flat surfaces like tees. The undulating greens have a thinner layer and I'm confident at this point that some sun will melt what is there.

If it remains next week, we will remove the ice from the most susceptible greens with shovels.

Coyotes

2011-12-20T07:03:00.002-05:00

Eastern Coyote Canis latrans

You will see coyotes on the golf courses in the winter. I’m not quite sure why they are more prevalent in the winter but it’s most likely due to the absence of humans and this is also their breeding period so they may be more active. Most of the sightings have been around holes 4, 2 and 7 on the South Course.

The following is taken from the MiDNR website where you can find more information on coyotes:

There is wide variation in the coyote's color, but generally their upper body is yellowish gray, and the fur covering the throat and belly is white to cream color. The coyote's ears are pointed and stand erect, unlike the ears of domestic dogs that often droop. When observed running, coyotes carry their bushy, black tipped tail below the level of their back.

Coyotes are opportunistic and will eat almost anything available. They will also prey on unattended small dogs and cats, if opportunities exist. Some coyotes learn to kill smaller livestock, such as sheep, goats, calves, and poultry. Larger animals are almost always consumed as carrion. Coyotes are active day and night; however, peaks in activity occur at sunrise and sunset. Coyotes generally feed at night.

Their presence in subdivisions and urban or suburban areas, while surprising to many folks, is a result of increasing populations (both coyote and human) and encroachment of human environments into their natural habitat (from development of rural areas).

A Great Staff

2011-12-19T12:18:00.000-05:00

2011 was the most difficult year to grow fine turf grass since 1995 and perhaps 1988 too, although 1988 was pretty tough.

Not only do we have a skilled, talented and hard working staff .... more importantly we have a crew made up of good people. Kind and respectful to one another, giving, caring and engaged every day to do what is right.

And it is very fulfilling to hear the crew say that of one another. I have heard repeatedly over the years a staff member speaking highly of the team we have assembled. It is very rewarding to know that the staff respects their coworkers.

So as the sun falls on 2011, I would like to thank my teammates for a spectacular year and for making it a joy to come to work each day!

Covering Greens

Let's Get Over Ourselves

2011-12-15T11:16:00.004-05:00

Stephen Covey writes: “It has been said that some people think they can push themselves forward by patting themselves on the back. But boasting merely amplifies the ego.”

The minute we start taking ourselves too seriously is the time that others won’t. Be certain that the work we’re doing can be done by someone else … and probably for less money. That doesn’t mean we can’t be confident; a universal trait of all winners must be confidence. The belief in yourself can build courage and you are more apt to take on new challenges if your self-esteem is high.

But when we hear a phrase like “it's my golf course” it could show a lack of many things: humility, respect, confidence and gratitude among many others. Someone else most likely owns the property you work and if you forget that, the owners won’t. If we believe that we’re the smartest in the crowd, our minds will be closed to new ideas and the insights of others. Humility can be the first step in empowering others to take initiative in problem solving and humility shows enormous confidence.

If we take credit for the work of others and attempt to take all the glory it shows everyone else that our needs are more important than theirs. It can be hard to define humility but I would guess we know it when we hear it.

So check your ego at the door and let someone else carry the trophy.

“Truly great men and women are never terrifying. Their humility puts you at ease. - Elizabeth Goudge

Winter Covers

2011-12-08T13:37:00.000-05:00

We finished installing the covers yesterday, the last piece of the "winter preparation puzzle".

Covers provide some insurance against winter damage by moderating the temperature underneath. They do not prevent winter damage, but appear to lessen the risk.

I'll be posting more information throughout the winter on our program of "winter survival". Monitoring the turf and the snow cover is a daily occurrence in the winter. Growing healthy turf is much more difficult in the winter than the summer!

Ron Bentley

2011-12-05T09:00:00.001-05:00

(In his younger days with the ever present smile!)

Ron Bentley started with us in 2001 as an intern from Rutgers. He stayed for 10 years, working his way up to Senior Golf Course Superintendent and was not only a trusted lieutenant, but also a peer and good friend.

His attitude, kindness and work ethic did not go unnoticed. He was recruited by a vendor and recently accepted a new position as a branch/sales manager for a new John Deere distributor here in Michigan. This will be "start-up" opportunity for Ron and keeps him in the turf industry and close to home in Grand Blanc.

His shoes will be too big to fill. But this is a great opportunity and we certainly wish him the best!

All but the Covers

2011-12-04T12:21:00.000-05:00

Thanks to the staff for coming in on a Saturday and working well past dark to get the greens topdressed and all but three of the covers installed.

We'll finish covering the remaining greens this week if the ground doesn't freeze.

Winter Preparation V - Topdressing

2011-12-03T11:15:00.001-05:00

Topdressing greens heading in to the winter provides extra protection against extreme weather. It also helps to firm the putting surfaces the following spring, eliminating the need to topdress greens in April when the greens are soft.

We are making every attempt to get this done this weekend before we get blocked by poor weather.

North Course Cart Access

2011-11-25T12:00:00.000-05:00

Saturday, November 26th - Final day for carts on the North Course.

Due to weather and the damage from cart traffic, tomorrow will be the last day for carts on the North Course. Turf cannot recover from traffic damage at this time of year as it enters dormancy. We are concerned that any damage now will be present next spring so in the interest of protecting our North Course, golf will be walking only.

Thanks for your understanding. Have a great holiday season!

Cold Turkey Open

2011-11-25T09:23:00.000-05:00

No frost today. So we're good to go at 10:30!

Winter Preparations IV - Fungi

2011-11-21T14:04:00.000-05:00

"Snow Mold" includes several diseases that occur over the winter, with or without snow cover. In a typical year, these fungi will not cause widespread death of fine turfgrass if treated preventatively with a fungicide. If left untreated, the damage can be severe.

The application of fungicides must be well timed. Just prior to soil freezing and before snowfall has worked best for us here at Oakland Hills. The application is usually best before any winter topdressing is applied and before the winter covers are installed.

This week we are applying a fungicide to all greens, tees and fairways to provide insurance against a heavy onset of snow mold. Some snow mold is always present in the spring, but the damage will be minimized by this application.

Winter Preparations III - Fertilizing

2011-11-18T08:25:00.001-05:00

Turfgrass under high demand needs food (nitrogen) late in the year. It's important for turf heading into the dormant season to be strong enough to withstand the difficulties of cold weather, ice and snow. By applying a quick release fertilizer in November, the grass plant can utilize part of the nutrients now, saving the balance for early next spring.

Wells for Irrigation

2011-11-16T08:16:00.000-05:00

We have 2 wells located left of #4 green that provide water for the South Course irrigation system. Each well is surrounded by native grasses and supply a total of 950 gallons per minute when both are working in tandem. The supply line runs through number 4 fairway, in front of #7 tee, in front of #14 tee/#13 green, then across #12 fairway and terminates at the pond on #16.

Water use is driven by two factors: member expectations and turfgrass needs.

Our annual water usage for the South is 41 million gallons (the North Course averages 33 million). This would be lower if not for two low rainfall years: 2005 and 2007 when we used almost 60 million gallons on the South. In 2005 we were also recovering from the Ryder Cup and in 2007 we were preparing for the PGA, both events drive up water usage on both courses.

In 2011 we used 32.4 million gallons on the South Course and 22.9 million on the North. These below average numbers are due to a concerted effort to lower water use and also the above average rainfall we received.

Winter Preparations II - Aerification

2011-11-14T09:11:00.002-05:00

As a part of getting the golf courses ready for winter, this past week we aerified all of the South greens and a few of the winter susceptible North greens.

Aerifying this late in the year results in the holes remaining open all winter. These open holes allow for better surface drainage when the snow and ice melts. It also allows for ice to form inside the open channels, causing an expansion of the soils surrounding the hole and providing another form of soil aeration.

Walk of Fame

2011-11-10T11:03:00.001-05:00

You may recall the work we did at the Walk of Fame this spring. The grasses we used will remain through the winter to provide a nice contrast.

Winter Preparations - Irrigation

2011-11-08T08:30:00.002-05:00

The South Course is closed to play as of yesterday, November 7th. The North Course will remain open to carts as weather permits.

We need 5 - 7 days to complete all of the winter preparations so we start next spring with healthy playing surfaces: todressing greens, deep tine aerification of greens, irrigation blowout, fertilizer applications to the entire golf course, fungicide applications to protect the turf from snow mold fungi, installation of green covers and leaf cleanup.

All of this work needs to be completed in good weather (no rain) so our window is very tight. The beginning of this week is dedicated to blowing out the irrigation system.

North Pump Station

Wild Ride

2011-11-01T07:55:00.000-04:00

The operator of this mini excavator had an interesting morning while cleaning up the edge of the pond on #14 North. Operator and machine are doing well after a tow truck arrived to pull them out.

Cart Access

2011-10-27T07:14:00.001-04:00

Legitimate questions have been asked about cart access after rain events. We are responsible for making the decision regarding carts, so let me explain the process:

Member access is the ultimate goal. We try to err on the side of allowing carts, even when it's too wet. We're in the service industry, so servicing members is our role. The sole question we ask ourselves is: will the members who play tomorrow, be proud of the golf course?

Financial considerations do not factor in. Nor whose name is on the tee sheet, nor the day of the week. Usually, when there are no carts on the South, carts are allowed on the North so the members have someplace to ride. All outside events get the same consideration. We have canceled two outside events this year due to wet course conditions.

Rain events in the summer are different from the fall. In summer, long days, high temperatures and actively growing grass remove water quickly. We routinely allow carts the day following a 1" rain in the summer.

Rain events in the fall occur with less daylength, cooler temperatures and turf that cannot "drink up" the excess water because it is not growing. One tenth of an inch of precipitation in the fall under these conditions is enough to cause wet conditions.

May 1st - September 30th:

Total precip: 20.87"
Avg for this period: 16.50"
No carts North Course: 5 days
No carts South Course: 20 days
5 total days where members had no access to golf with a cart

Frost

2011-10-24T07:28:00.001-04:00

Frost is basically frozen dew that has crystallized on the grass, making it hard and brittle. A grass blade is actually 90 percent water, therefore it also freezes. Because of the short mowing height (sometimes as low as 1/8 inch) and fragile nature of the turf, putting greens are most affected by frost. Walking on frost-covered greens causes the plant to break and cell walls to rupture, thereby losing its ability to function normally. When the membrane is broken, much like an egg, it cannot be put back together.

As golf enthusiasts we do not like to delay play, but they are more concerned about turf damage and the quality of conditions for the golfer. Frost also creates a hardship on a golf facility's staff as all course preparations are put to a halt until thawing occurs. Golf carts can cause considerable damage, therefore personnel cannot maneuver around the course to mow, change cup positions, collect range balls, etc.

You can learn more about frost on the Common Questions page on this blog.

14th Annual Golden Rake Tournament

The fairway enlargements on holes 4, 6, 11, and 12 are complete. The remainder will be finished next year.

On #11, the new fairway width is 47 yards in the "member zone".

On #4 the new fairway width is 35 yards, an additional 10 yards wider.

Deep Tine

2011-10-12T09:20:00.000-04:00

"Deep Tine" is the term we use to explain aerification that goes deeper than a typical core aerification on greens, tees and fairways. A routine aerification might go to a depth of 2-3". When we use a larger machine with a longer tine the depth can reach as far down as 10 - 12" or more.

On fairways, we perform a deep tine aerification two to three times per year. Solid, 3/4" tines will penetrate below any hardpan layers (created by years of aerifying to the same depth) and shatter the soil. Fissures are created by vibration movement of the machine thus improving water and air movement.

Disturbance is minimal and the improvement in playing surfaces is enhanced.

Member Improvements VI

2011-10-10T16:04:00.001-04:00

The bentgrass sod was finished today. The staff laid about 12,500 square feet of sod on #11 fairway, thus adding a total of 1/3 acre of space to the member landing zone. The new bunker on the left is about 175 yards from the middle of the main tee pad.

All of the forward tees are finished. The fairway enlargements will take place slowly this fall as time, weather and staffing permits. The remainder will be completed in 2012.

Member Improvements V

2011-10-06T16:22:00.001-04:00

Beautiful weather eh? It helps to have some sun and dry conditions to play golf ... and to lay sod. Today we finished the bunker on #5 green and the new forward tee on #5 and made great progress on #11 fairway.

The staff worked hard to get a full semi load of sod down. We'll finish the remainder of the sodding next week.

Sewer Line Work

2011-10-03T10:52:00.000-04:00

The township is inspecting and repairing the sewer/drainage line that runs along the North side of the South Course. The work should be completed this week.

Carts

2011-09-30T12:29:00.001-04:00

Whenever we make the decision to pull carts on either golf course it disrupts not only club operations, but also the schedules of members, guests and employees. The usage of the club decreases too and that has a financial impact.

There is only one good reason to prohibit carts: to protect the golf course(s).

We are close to the wettest September on record and we have restricted carts more often than in most years. It's no fun for us to eliminate cart usage ... and it's frustrating for members. But when necessary to protect one of the great pieces of property in all of golf, carts need to be restricted.

Thanks for your patience and understanding this week.

Member Improvements IV

2011-09-29T16:08:00.001-04:00

The bunkers on #11 are close to the finish line. Today we added sand and partially sodded the perimeter.

Weather tomorrow will delay us until next week, but still anticipate finishing by next Friday.

Bunker #11 Fairway

2011-09-27T10:22:00.003-04:00

Today we finished the shaping on the new bunker on #11 fairway. Bryce Swanson from Rees Jones' office was here to approve the final look and to paint the bunker line and the new fairway edge.

It looks great and the plan is to install irrigation this week and sod at the beginning of next week.

Member Improvements III

2011-09-26T09:51:00.001-04:00

Grub Damage

2011-09-21T16:39:00.002-04:00

"Grubs" is the term used to describe the larval stage of several species of beetles. They damage turf (and lawns) by feeding on the roots of grass plants. They typically appear in the Midwest in mid to late summer after the adult beetles have laid their eggs in the soil.

The North Course fairways have been hit hard this fall even though a preventative treatment was applied in late June. We're not sure, but perhaps the heavy rain we experienced this summer caused the chemical to leach through the soil.

Most of the damage you see is from skunks and raccoons digging for their next bedtime meal. We are applying a curative treatment which will get the problem under control in a couple of weeks.

Temporary Greens II

2011-09-08T16:12:00.000-04:00

With the rain, the greens drainage project has been delayed.

We will continue to work on numbers 8 and 15 on Friday and Saturday, finishing on Monday of next week if necessary.

Temporary Greens

2011-09-07T13:04:00.000-04:00

The drainage installation on numbers 3, 8 & 15 is taking a little longer than expected and it will be necessary to use temporary greens while the work continues. We should finish by late Thursday, possibly into Friday morning.

We scheduled the work during aerification week to keep the disruption to a minimum.

Once all three greens are finished we will see a dramatic improvement in the internal drainage, just like we witnessed on #15 North and #2 South.

Thanks for your patience!

Big Day

Today we seeded the new fescue areas left of #4 and behind #3 green. We are using a blend of 40% Sheep fescue and 60% Hard fescue.

It will take 3-5 years to mature but we are confident it will continue to improve the aesthetics of the South Course. The feedback so far has been very positive.

2011-08-31T09:38:00.000-04:00

The existing fescue area on the South Course was mowed yesterday. Applications of herbicide are more effective if the product can reach the low growing weeds and for that to happen we need to cut down the grass to a reasonable height. Mowing also eliminated volunteer trees that sprout from seed.

This is a routine practice that in future years will occur later in the fall. On relatively young fescue stands it's important to get this mowing completed early so seeding can also take place while temperatures favor germination.

Here We Go!

2011-08-29T06:45:00.002-04:00

WHY AERIFY?

CORE AERATION is one of the “dirty” words of golf course maintenance. With a golf season of seven months, many would question the necessity of disrupting play each spring and fall.

An important purpose behind core aerification is the removal of unwanted organic matter, allowing roots to grow. With a healthier root system heading into the golf season, the grass plant is better able to withstand the stress of traffic. Aeration also relieves compaction, promotes air exchange and helps with water infiltration.

How much aerification is enough?

There is no rule of thumb for what percentage of surface area should be impacted each year. It would be safe to say however that it is difficult to “over aerify”. The USGA suggests that 15-20% of the surface should be aerified each year. This would dictate a larger hole size – and closer spacing between holes during the aerification process – both spring and fall. Changing from a 1/4” tine to a 1/2” tine increases the surface area impacted by four times. Using a 5/8” tine versus a 1/2” tine increases the surface area impacted by approximately 50%.

How long after aerification before the greens are back to normal?

With cooperative weather, the healing process will take 10 - 14 days. Extra fertilizer and water are applied at this time to expedite recovery.

Member Improvements II

2011-08-24T09:13:00.001-04:00

Fairway Widths

Along with adding some fescue areas to improve aesthetics, Rees Jones also added a little width in the "member landing zones". This will not affect championship play and the Green Committee felt it would enhance the member experience. The Committee has been very responsive to member commentary since the renovation in 2006 and agreed that the landing zones could be a little more generous.

We start the sodding process next month and will focus on holes 4, 6, 11 and 12.

The photos below are examples of the fairway enlargements. The red flags will be the new fairway lines.

South Course Member Improvements

2011-08-22T15:38:00.003-04:00

Rees Jones has made several "tweaks" to the South Course; minor improvements to help with member playability. In addition, he added more fescue areas. We will begin site preparation for the fescue behind #3 green and left of #4 fairway tomorrow. Both of these areas were vendor compounds and corporate villages during our prior championships and set up well to "go native".

Roundup to kill the existing vegetation will be applied tomorrow and seeding next week. Today and the remainder of this week will be spent removing the dead/poor quality Spruce and Pine trees in these locations.

As with the fescue area between #6 and #14, it will take 3-5 years to fully mature.

Fertilizing Fairways

2011-08-16T10:02:00.003-04:00

Now is the time to think about fall fertility. The next 4 - 6 weeks is the perfect time for cool season grasses to recover from the stress of summer and the grass plant requires an available food source (Nitrogen) to make that happen.

If fertilizing at the beginning of this fall cycle, a 100% coated (slow release) product is best so that the Nitrogen is available throughout the month of September into early October. It also reduces the burn potential if using a slow release (coated) fertilizer in August.

A coating refers to a covering applied to a product to modify or enhance its properties. In the case of fertilizers, it controls the release of nutrients in to the soil. The heavier the coating, the slower and longer the release rate.

This week we are fertilizing the fairways on both courses to help prepare the turf for fall aerification and to facilitate recovery from a difficult summer.

Driving Range Tee

2011-08-15T14:47:00.003-04:00

Aerification and overseeding works. At least on our bluegrass and ryegrass range tee. Overseeding greens is more inconsistent due to the close mowing height, but on our practice tee we got great germination from last weeks overseeding. The tee has a ways to go before it recovers from the heavy use it sees, but I'm confident that by late September, we'll see nearly full recovery.

The Short Game area too is getting heavy use and it's wonderful to see the members enjoy this facility. In general, the members do a great job of course care on the Short Game Facility, so keep up the good work there and on the golf course.

Flowers

2011-08-10T15:37:00.001-04:00

Our gardener, Heidi Cook has brought a fresh look to the clubhouse flower beds. New pots, new varities and new ideas have made this a great year for flowers at the club. Our big "re-do" of the Walk of Fame has been well received and we are planning new and fresh ideas for this fall and next spring.

Course Status

2011-08-09T06:00:00.000-04:00

Tuesday, August 9th: .80" as of 6 am.

South - no carts all day.

North - no carts this morning, we'll evaluate again at noon.

Fungicide

2011-08-05T13:51:00.000-04:00

Fungicides are pesticides, or plant protectants, that kill or prevent the growth of fungi that cause disease. Preventative treatment is preferable on greens and tees as lower rates can be used if you are ahead of the disease. On fairways, this approach is more expensive because the acreage is larger: we have 8 acres of greens as opposed to 60 acres of fairways.

Greens are sprayed every week and fairways are sprayed as needed, about every 14 to 21 days in the stressful period of summer, Memorial Day to Labor Day.

Course Status

2011-08-03T07:21:00.003-04:00

.70" of rain this morning.

South - No carts

North - Carts OK

Since July 27th, we have received 4.2" of precipitation.

Driving Range Tee

2011-08-01T15:18:00.000-04:00

With limited space and exceptional use, the range tee is taking a beating. In 90 degree heat, little if any seed will germinate so the tee has begun its inexorable march downward.

However, that doesn't mean we've given up and we still are giving it the "full court press" until cooler weather arrives. Today we aerified and overseeeded, fertilized and watered. It's a little hot to be aerifying but I think it's worth the risk to get some recovery.

I would expect excellent recovery later this fall.

Course Status

2011-07-28T06:45:00.002-04:00

2.3" of precipitation so far.

No carts all day South Course.

North Course will be evaluated at noon for cart access.

Irrigation Pressure

2011-07-26T17:01:00.000-04:00

The "heat dome" we are experiencing puts pressure on everything and everyone. The turf feels it and so does the irrigation system. A sophisticated watering system like ours is very reliable but it too is under enormous stress from the constant usage.

Recently, the VFD (Variable Frequency Drive) that operates the pump motors failed on the North Course pump station. Luckily, a reliable vendor was able to find a replacement in California, overnight ship it to us and had it reinstalled in about 36 hours.

We missed only 2 nights of watering and due to the pump stations capacity, we were able to catch up rather quickly.

Hand Watering

2011-07-22T11:16:00.000-04:00

Hand Watering vs. Syringing
by Shane Lohman, ISU Turfgrass Intern

Hand Watering and Syringing are two very essential watering practices used on greens during high stress periods.

Hand watering is normally done in the morning with the sole intent to move water down into the root zone for uptake by the turf.

Syringing is typically done during the midday heat to cool the leaf tissue and to remove sugars released during photosynthesis. Syringing the turf is a light application or misting that does not allow the water into the root zone.

Both of these techniques are of vital importance in maintaining consistent dry surfaces without the use of sprinkler heads. These practices allow the application of water to go exactly where it is needed.

Hand watering and/or syringing cannot be scheduled around play, and can occasionally cause some minor inconveniences to the players. Not allowing these timely needed cultural practices to avoid disrupting play can lead severely stressed turf or even turf loss.

Piper

2011-07-21T06:54:00.001-04:00

The club's annual invitational event gives us the opportunity to showcase what we do. It's fun getting the courses in tournament condition even through the weather challenges this week.

The heat is harder on the staff than it is on the turf. It is simply too hot and too dangerous to ask the staff to work the 15 hour day we would normally experience during Piper preparations. There are some things "outside the ropes" we won't attend to, but the product we provide is still tournament worthy.

Greens speeds may be a bit slower too. Our objective until the heat breaks is firm and fast conditioning ... on a living playing surface.

Rees Jones Visit

2011-07-19T15:50:00.000-04:00

The Green Committee and Board have been discussing the idea of adding more fescue to the South Course but wanted to make sure we have our architect review and approve it first. Rees came in yesterday and also looked at some of the bunkers, ladies tees and fairway widths. He will produce a report for the committee and that will be forwarded to the Board for approval.

Heat Stress

2011-07-18T18:49:00.000-04:00

It's no mystery that it's hot. The turf likes it no more than humans and it too requires frequent watering. We keep the night irrigation to a minum which means we'll be out in play hand watering "hot" spots. Please excuse the interuption but hand watering keeps the surfaces dry and firm.

North Course Fescue

2011-07-15T13:49:00.000-04:00

The North Fescue area between #12 and #14 was seeded this spring. It gives us a comparison to the fall seeding last year on the South Course.

As you see, the annual weeds are getting aggressive. We cannot safely apply herbicides in this weather so we'll plan those applications for October. It will be spectacular next year after a full season of maturity.

The seed varieties we used on the North are the same as the South but in different ratios, so the look will be similar.

Man's Best Friend - by Shane Lohman, Turfgrass Intern

2011-07-12T15:24:00.000-04:00

Man’s Best Friend

For ages the term “Man’s Best Friend” has always been a furry four legged, tail wagging bundle of joy otherwise known Canis lupus familiaris or a domestic dog. This is not the case for a golf course superintendent. The item I’m referring to as “Man’s Best Friend” is called a soil probe. Every superintendent has one with them 90 percent of the time and will not venture on the course without one.

Throughout the summer I have been asked numerous questions about this item in particular and the information gathered by its use.

“What does that tool do?”

“What does it test for?”

“What are you looking for?”

The basic definition of a soil probe is a tool used to remove a deep core from turf areas to examine root development, thatch depth, soil arrangement and soil moisture.

Some consider checking your soil profile an art form. You have to use your senses of sight, touch, and smell. (Yes even smell; Anaerobic is a term used to describe a soil that is deficient in oxygen; saturated due to poor drainage. Oxygen is imperative for healthy greens by promoting beneficial microbial activity and decomposing organic matter. Insufficient oxygen begins a downward spiral of problems that does not end well. These soils will have a very foul smell associated with them.)

While evaluating your soil probe plug general questions are asked: does the soil form a “ribbon” between the fingers or does it crumble or fall away? This gives us the information of moisture content in the underlying turf - if it ribbons it means it’s holding moisture; if the soil breaks away or crumbles, the turf is dry.

During the summer, soil moisture is the most important aspect of the keeping healthy turf that maintains consistent playability. This is very hard to tell if you don’t look at the underlining soil to identify the amount of water present. The rule is to keep the turf as dry as possible because it is much easier to add water then to take water away. And too much water can lead to higher disease pressure and maybe turf loss.

Soil probes allow the superintendent to keep adequate moisture levels and to allow more efficient watering, better playing conditions, and healthier turf.

Irrigation

2011-07-11T11:30:00.001-04:00

Most of our irrigating occurs at night between 9:00 pm and 4:00 am. On occasion, we water during the day to wash in fertilizer or as is the case today, topdressing.

Thanks to our new (2002) irrigation systems we are able to handle the current heat stress. One staff member spends all day every day checking and repairing the irrigation systems, assuring that our investment functions correctly.

Roots

2011-07-08T12:29:00.003-04:00

What goes on above ground is directly related to what is happening below ground. You cannot have good quality putting surfaces without a dense and healthy root system. Roots are the heart of any turf stand. They provide water and nutrients to the shoots of the grass plant. So superintendents are continually talking about roots.

Annual bluegrass (many of you refer to as poa) is notorious for weak and shallow roots, particularly when the shoots are constantly chopped off at .100 inches ... or less. The South greens are predominantly annual bluegrass. The newer bentgrasses were developed with a much denser and vigorous root system, allowing the shoots to tolerate closer mowing and leading to faster and smoother putting surfaces. The South practice green is comprised of L93, A1 and A4 bentgrasses with some minor annual bluegrass encroachment.

This photo shows the difference in rooting depth between the newer variety PG bentgrass plug (left side and center) and an older annual bluegrass core from #9 green (on the far right). The bentgrass roots extend into the native soil and the annual bluegrass roots do not. The deeper root system provides a better putting surface.

What's That?

2011-07-05T12:09:00.001-04:00

Number 1 tee on the South Course had a large brown spot with the shape of a footprint in the middle of it. Any guesses?

Most likely it's a player applying bug repellent on their legs or ankles. Something like "Off" when applied on a hot day, will tip burn the turf. So please apply the bug spray on a cart path or in the parking lot.

Drainage #18 South

2011-06-29T09:35:00.002-04:00

The last fairway bunker on #18 South sprouted a wet spot. Perhaps due to the wet spring or maybe just an old broken drain line. Yesterday we installed an interceptor drain to catch the ground water before it enters the bunker. At the same time we replace all the sand in the bunker that had become contaminated from constant saturation.

Topdressing

2011-06-27T15:57:00.000-04:00

Today we topdressed the North greens.

Topdressing with sand is the most effective means of diluting thatch on putting surfaces. There are additional benefits:

smooths the putting surface
helps eliminate or minimize "grain"
provides a firmer surface

Light and frequent topdressing is preferred as long as there is access to the golf course to get it done. We avoid topdressing on days when the temperatures are in the high 80's or low 90's due to the abrasive stress on the turf.

Fescue Update South Course

2011-06-25T09:31:00.000-04:00

The area between #6 and #14 is progressing well for its first season, exceeding expectations. As stated prior, it will take 3 - 5 years to fully mature, but so far, we're very happy and the feedback has been great.

The creek bank (that looks green) will need some attention and will also eventually look like the remainder of the area. We are applying a herbicide this week and again later in October to remove most of the weedy grasses along the creek.

Also in late fall we'll be making another herbicide application to remove or reduce the annual bluegrass throughout the native area.

Square Tees

2011-06-24T05:58:00.001-04:00

The Green Committee has discussed the possibility of converting our "free form" tees to "square tees". Square tees were prominent when Oakland Hills was built and are a feature on many traditional golf courses.

In an attempt to see if this is feasible, yesterday we converted #18 tee on the North Course from free form to square. This will give us the road map we need to calculate the costs and timeline to get the work done. The tees can be converted back at any time.

Dew Point

2011-06-21T13:22:00.005-04:00

The "Dew Point" is a very important metric in turfgrass management because it's an indicator of disease potential. Many fungi require free water for spore germination and thus we consider dew for extended periods to be a bad thing.

Dew is moisture formed by condensation of water vapor on a cool surface. It occurs mostly at night and for our discussion, occurs on the leaf surface.

The dew point is the temperature at which the air can no longer hold all of its water vapor and it must condense into a liquid, in our case, as dew. Simply, it's the temperature at which dew forms.

If the dew point is high on a summer night, say 72 degrees, it means that as the temperature cools to 72 degrees, dew forms. Therefore, the chance for disease is greater with a higher dew point for as you recall, fungi need free water for spore germination.

With high dew points, we scout rigorously for disease and when appropriate apply fungicides to protect the turf.

Lawn Clippings

2011-06-18T06:46:00.001-04:00

I have had several people ask about catching clippings when mowing, either here at the course or at home. Contrary to popular belief, returning leaf clippings does not substantially contribute to the buildup of thatch as leaf tissue is composed of about 90% water. (Over fertilization is the main culprit to thatch accumulation.)

Returning clippings adds needed nutrients to the soil. Research has shown that lawns where clippings are returned have a darker green color and need less Nitrogen. It is also good for the environment: removed clippings must be either stockpiled or composted.

From the Archives

2011-06-16T09:19:00.002-04:00

From the forbidden jungles, located by a team of intrepid explorers, comes a long lost manuscript from the early years of sir Al Prevost. Once thought to have perished in a suspicious blaze, this little known work was reportedly penned during one of Al's self discovery trips to the wilds of South America.

Here, for the first ... and perhaps only time, is a seminal work by one of golf's great scribes.

The Captain

Yes, I'm captain of an industry

and golfing is my game,

and when I leave the course

it never is the same,

Cause I seldom fix a bunker

or a ballmark on a green,

and my divots in the fairway

just litter up the scene.

Oh, I'm captain of an industry

and always pay my dues,

which I believe entitles me

to do just what I choose,

so I drive my little golf car

where' ere I want to be,

without regard to path or sign

or bunker, green or tee.

Hey!, I'm captain of an industry

and rules I don't abide,

I do my thing the way I want,

the way that I decide,

Codes of dress and rules of golf

I basically ignore,

for captains such as I , I'm sure,

find restrictions such a bore.

So if you see a captain

who's tearing up the course,

It's sure to test your patience

as you realize the source,

and you know it won't be helpful

no matter what you do,

but think about the way you play

so the captain isn't you.

Sir Al Prevost

Just .14" of rain last night, so no restrictions on play or access.

Monday Projects

2011-06-14T06:37:00.002-04:00

The importance of allocating time for the Golf Course Staff to do important maintenance cannot be understated. Sometimes it seems like us "greenskeepers" are pressing too hard to get the course closed one day per week to get some of this stuff done. Because we close the South Course to play after outings, here is a list of stuff we were able to do yesterday after the event finished:

sprayed South fairways
sprayed North Course greens
aerified range target greens
renovated 5 range bunkers
trimmed and edged South bunkers
topdressed South Course greens

Fescue

2011-06-13T10:10:00.001-04:00

The fescue (native) area between number six and 14 South is progressing well. The seed heads are starting to mature and in another month will turn brown. The blue color you see is from the sheep fescue, the greener grass is hard fescue.

The annual bluegrass (poa annua) is quite thick and will require an application of herbicide this fall. If we can get the annual bluegrass under control, it will make the stand much thinner and more playable.

Give this area three to five years to fully mature.

Course Update

2011-06-11T08:56:00.000-04:00

.33" of precip last night was a welcome relief for both courses. A little rain and cooler night temperatures helped the turf to recover from the prior week of heat.

Since we missed topdressing greens this past week, that is on the schedule for the South Course on Monday. With the Member/Member next weekend, most of the upcoming week will be course preparation.

The driving range tee is taking a beating. In order to have good turf on the tee in August, we'll need to use the front pad and the matts more often.

Wetting Agents

2011-06-08T13:40:00.001-04:00

Wetting agents are surfactants.They act by modifying the surface tension between water and another surface, like leaf blades or soil particles.

A wetting agent is a product used in golf course management to increases the ability of water to penetrate soils. It decreases the surface tension of soil particles making it easier for water to infiltrate and spread through the soil profile. It makes water more efficient.

We use wetting agents on both courses to improve the effectiveness of nightly irrigation. In periods of stress, the improved water effectiveness helps us combat dry spots when we hand water. It also helps roots get the water they need to keep the grass plant alive.

Heat Stress

2011-06-07T18:33:00.001-04:00

It may seem odd after that much rain in April and May but the golf courses are VERY dry and it shows. The South fairways in particular are struggling although, this is temporary. We were obligated to mow them last week when they were still a bit soft and that resulted in some scalping.

Scalping occurs when you mow off most of the leaf tissue and below the growing point of the plant. Not good. We raised the mowing height on fairways until we get through this stretch of weather and until the turf recovers, maybe next week.

The greens are doing fine, the annual bluegrass seed heads have died, turned brown and will soon disappear.

Drainage

2011-06-03T14:28:00.001-04:00

The last of the North Course bunkers to get drained, number two green, were done this past week. This was part of the North bunker and drainage project we undertook last fall. We simply ran out of time and weather at the end of the year so we finished them this spring.

Ketchup

2011-05-31T14:43:00.000-04:00

Last night we brought in a crew to mow fairways. The fairways are so long (they haven't been cut since last week) it was important to avoid the morning dew and get a dry cut. I'd like to thank my staff for coming in on their day off to get this done.

Today we were able to catch up on the mowing we haven't done since last Thursday. We cut about 75% of the rough today and should get a better cut tomorrow and the following days.

The course is still a little rough but I'm confident that in two or three days we'll be back to normal.

SRS Progress Report VI

Another bit of rain last night on 2 saturated golf courses:

No carts all day, either golf course.

7" of precip for the month of May.

Course Update

2011-05-28T09:31:00.001-04:00

As you know, the weather has been almost historical. There have been wetter years for sure, but this spring is one we will all remember. Since May 1st we have received about 6.5" of precipitation.

Currently, we are not able to mow anything but greens on the South Course, including the rough. Today we are bringing out our "mothballed" walk behind rotary mowers, kept in a storage unit the past 2 years. If we cannot use the larger rough mowers on the golf course tomorrow, we will begin hand mowing fairway perimeters on Monday.

The North Course is slightly better. Carts are OK today pending any further rain events, although it too is saturated.

If the 5 day forecast holds, the staff will make the necessary sacrifices to get the golf course mowed and back in the condition you expect. Thanks for your patience.

Course Status Thursday, 5/26

2011-05-26T05:43:00.000-04:00

2.53" of rain last night.

SOUTH COURSE:

No carts North until further notice.

Fertilizing Rough

2011-05-23T15:35:00.000-04:00

Are you kidding?

Even turf that appears healthy and vibrant in the spring will need a little food later in the summer.

The 100% slow release fertilizer we apply this week will release throughout the summer when cart traffic peaks.

Very little Nitrogen will be immediately available in the next 2 weeks while the grass is experiencing its spring growth phase.

Annual Bluegrass and the South Greens

2011-05-21T08:41:00.003-04:00

The South Course greens are composed of a mixture of several varieties of older bentgrass and Annual Bluegrass or "poa annua".

Annual bluegrass is more prolific and competitive under an ecological regime of close mowing, light frequent irrigation, high fertility, and moist soils. It is a winter annual that germinates in late summer/early fall, once soil temperatures have dropped below 70 degrees F. Seedlings mature in the fall, overwinter in the vegetative state, and produce seed in late spring and early summer. Some germination of annual bluegrass seed also occurs in the spring. The seed may lie dormant in the soil for many years before germinating, resulting in a significant build-up of indigenous seed overtime. It tends to be more prolific during wet seasons. Annual bluegrass often dies in the heat of the summer due to heat and drought stress, disease, and/or insect damage.

Annual Bluegrass is a prolific seed producer in the spring, giving the putting surface a white appearance. This seeding also causes the bumpiness you see and feel. In 10 - 14 days the seeding will subside and the greens will return to normal.

Mowing Rough

2011-05-19T06:53:00.000-04:00

A challenge in the spring is keeping up with mowing the rough. We have 5 rough mowers operating 10 hours a day and 6 hours Saturday and Sunday ... if the ground conditions permit. Losing 1 day to weather makes it virtually impossible to reschedule those lost 50 man-hours and so we find ourselves playing "catch up" most of the time.

Combine that lost mowing time with the annual seed head production of bluegrass and ryegrass and you have very thick, long rough and difficult playing conditions.

The bottom line is that rough grows aggressively in the spring, even in the absence of fertilizer applications. The result is difficult playing conditions, and this occurs every year. The only solution is to hit the ball in the fairway, play hard when it is in the rough, and know that the growth rate of the grass will slow down as spring progresses into summer.

We'll keep the blades turning as frequently as we can and drier weather will be here soon.

Status for Wee One Outing

2011-05-16T07:04:00.000-04:00

Current conditions: at this hour we are planning on allowing carts for today's Wee One Outing, however any more rain will require us to reevaluate. A final decision will be made at 11:00 am.
