After frost and rain, root shearing poses a hidden threat to golf greens. Learn more about this issue!
Probably the most used picture in @greenkeeping this morning, after several days of hard frost we’ve had a sudden swing in temps plus heavy rain. This creates an unseen problem: root shearing, where the top profile of the green appears to be thawed but in reality, it’s only the top inch or two. This creates a problem when you walk on the greens; the motion of your feet makes the roots underneath sheer away from the top profile and bottom, creating damage that we don’t all see. Unfortunately, the short-term pain of winter greens equals long-term healthier greens.
What is Root Shearing?
Root shearing is a phenomenon that can occur when the top layer of a golf green thaws while the deeper roots remain frozen. This discrepancy can lead to damage when pressure is applied, such as when golfers walk on the greens.
Impact on Golf Course Maintenance
Understanding the effects of weather on greens is crucial for golf course maintenance. Proper care during these transitional periods can help mitigate long-term damage.
