Which cultural practice is recommended to reduce winter injury?

• A. Water adequately in fall and mulch
• B. Fertilize heavily in winter
• C. Prune in summer
• D. Irrigate only in spring

Answer: (A)

Winter injury in turf often comes from desiccation and stress during cold, dry conditions. The best way to reduce that risk is to support the plant with fall care that preserves moisture and shields crowns through the winter. Watering adequately in fall ensures the root zone stays moist as temperatures drop, helping the turf store energy and withstand desiccating winds. If the soil dries out before winter sets in, the exposed leaf tissues and crown can desiccate, leading to winterkill. Mulching around the base of the turf or over bare soil adds a protective layer that slows evaporation, moderates soil temperature, and cushions crowns from freeze-thaw cycles and heaving. Together, fall irrigation and mulching provide moisture and thermal protection that significantly lowers winter injury risk. Fertilizing heavily in winter is not advised because it encourages new growth when roots are withholding moisture and temperatures are unfavorable, making the turf more susceptible to winter damage and disease. Pruning in summer doesn’t address the moisture and protection needs of winter, and irrigating only in spring leaves the turf exposed to drying conditions in fall and winter. So the combination of fall water and mulch directly targets the causes of winter injury and is the most effective practice.
