Topdessing Greens

Today we are starting to topdress the greens on the South Course. This is the last heavy topdressing prior to winter and it provides some protection from severe weather and eliminates the need for us to topdress the greens in the spring when conditions are moist and soft.


The following exerpts regarding topdressing in late fall are taken from the USGA Green Section Record-


From 1924:

A good many observations have been made on the effects of winter weather on putting green turf and' on the effect of covering greens for the winter months. The studies thus far conducted indicate quite clearly that there are relatively few cases where either the bents or fescues are appreciably damaged by winter factors except in situations where either the surface or sub-surface drainage is inadequate. Ice sheets may be formed even under conditions of good drainage, and these have been known to injure putting greens, but ice sheets thus formed produce injury so seldom that winter-killing may generally be regarded as a direct result of poor drainage.

From 1969:

Protects Against Winter Kill: Years of experience and research have shown that greens top-dressed just prior to the winter have fewer problems from desiccation and winter injury. The crown of the plant is protected from the winter's drying winds and wide temperature swings.
