Pictured above is turfgrass that has suffered winter injury due to foot traffic over the lawn while covered with ice and snow—clearly showing footprints where the damage occured. Although the turfgrass pictured above isn’t a common grass in this area and any damage done to southern turfgrasses won’t manifest until green-up begins; it demonstrates how easily damage can and will occur, if special care isn’t taken to keep traffic off of your lawn in periods of extreme and unusually cold weather.
