When there is an extended drought and inadequate rainfall, survivability of turf is always a question. Most cool-season grasses, especially tall turf fescue, can withstand extended high temperatures and insufficient moisture. Provided that your fescue lawn is growing on deep, non-compacted soil, its deep root system could very likely have brought it through the drought. However, damage and thinning of grass can occur.
To determine the condition of your lawn, observe individual crowns of several plants to look for signs of life. Even if you see some green tissue, you will not know until the break in dormancy the extent of recovery. Then make a decision on whether to overseed or renovate the lawn. If possible, do not overseed or renovate until the weather, especially night temperatures, is cooler. Generally, cool-season grasses can be established during the early fall. Whether you need to establish a new turf, renovate, or overseed, guidelines for making good cultural decisions and seed selections are available from your local Extension office.
