When turf and trees share the same landscape, turf is often on the short end of the relationship. Warm season grass species require a daily minimum of six hours of sunlight to survive. Any less and the turf will develop a symptom known as lodging (a spindly, weak growth habit) and the grass stand will begin to thin. In
this weakened condition, the turf is predisposed to traffic injury and oftentimes becomes overrun with weeds. However, the impact trees have on turf is not limited to the shade pattern they cast. Turf growing adjacent to trees is also negatively affected by tree root encroachment. Tree roots deprive the turf of nutrients and water resulting in drought damage, chlorosis(yellowing), and weakness.
The Agronomy team at Colleton River Club continually evaluates the relationship between the trees and the turf and selectively trims and root prunes trees to reduce their impact on the turf. During the most recent course closure, we used the Imants Root Pruner to help minimize the problems associated with root encroachment. This machine uses a series of twelve-inch rotating blades to sever surface roots and help protect the turf. Done properly this equipment can help balance the relationship between turf and trees without causing long term damage to either. Next time you are on the course, take a moment to appreciate the majestic trees and the shade they provide, but consider how they might be affecting the turf.
