SL,
I'd like to know how much the process costs, and the down time at the various regions of the country
I can give you an example from Memphis.
In about 1991,we went from common bermuda to penncross bent--for the single,misguided reason that "everyone else is doing it".
After 25 years of fighting a losing battle,even with enough fans to power a small city,we re-grassed with Champion.As is common in this area,we re-grassed on 5 July and putted on the new greens Labor Day weekend.We have 20 greens,about 120,000 square feet in total,and the all-in cost was about $105,000.
We altered no contours but re-captured some lost edges.We did nothing to any approaches nor any surrounds.
