We are adding 2 acres of fairway space, mostly in the "member" landing zones. In most areas, this is being accomplished by using aerification plugs. It is labor intensive but saves us some money on sod. More importantly, it provides a seamless transition between the existing turf and the new expansion. Sod can take 3 or 4 years to blend in but by using aerification plugs we are establishing an identical stand of turf in the new expansion zones.
