My previous post regarding winter preparation touched on many subjects. An important practice that is completed is a sand topdressing of the greens. We topdress during the playing season as a way to firm and smooth the putting surfaces. Additionally the sand provides protection to the crown of the grass plants, which unlike most plants, is at the base of the plant. The crown is the point at which new growth takes place. If the crown is healthy and in tact, it is capable of producing new leaves. Winter weather produces conditions that threaten the health of the turf crowns that causes damage to manage in the spring.
Each Fall, prior to tarping the greens we apply a layer of sand to the greens. This year was no different, though we upped the volume of sand applied. By creating a layer of separation between the turf and any potential ice buildup stands to help keep the turf healthy without compromising air exchange and water drainage. The sand can also protect the wind from desiccating the plants when conditions are bare (common around these parts the last few years!)
The sand washes into the canopy of the turf on the greens and is not visible when spring arrives. If you check out the articles section of the website a USGA article has been posted that goes deeper into the advantages of this cultural practice. Given the crazy weather we have had in December and to begin January, I think it was a good thing to accomplish!
