Can someone explain the differences between the various strains of grass, in how they play for the golfer on putting greens? A few words on their maintenance/cost benefits would be interesting too.
I guess I'm kind of looking for a short primer on grass types, as I know next to nothing about them.
Jim, Im not a professional but I stayed at a Holiday..........
What I will say is Poa is a non-homogenous group of plants that is invasive and pervasive, particularly as Mike said in the Pac NW. Listed as a noxious weed by the State of Washington, the cool and damp conditions in the NW are perfect for Poa. It creates a softer surface and requires aggressive verticutting to remain firm. The various strains create an issue f bumpiness because strains grow at different rates during the day. Seed heads are a problem in the spring through the end of June. It also tends to be prone to disease.
With those problems, growth regulators, aggressive verticutting, grooming and wetting agents can create a tremendous putting surface in the right climate, like the Pac NW. Poa has no real grain, it can be cut very low and since it is so aggressive it is tough to kill in this area.
