What should I do if I allow the lawn to go dormant, but the dry weather persists through the entire summer?
Dormant lawns are in jeopardy of dying if dry conditions persist over an extended period. It's best to water the lawn if the turfgrass has been dormant for 4 to 6 weeks. Apply 1 to 1 1/2 inches of water in a single application. This will not cause the grass to green up, but it will keep the turfgrass crowns and roots alive. If the dry weather persists, water the dormant lawn approximately every 4 weeks.
