At this time of year the collars start to show some wear and tear from the traffic, compaction and the heat and humidity of the summer. Collars typically recieve twice the wear of a green. Golfers tend to walk on the collar, we go over it with the greens mower, collar mower and the roller. Often turning is avoided on the collar, but sometimes bunker placement and greenside mounds make turning on the collar unavoidable. This morning we vented the collars with needle tines and followed up with an overseeding of bentgrass and a roll. This is a very nondisruptive process and will show great benefit in the long run.
