Answer: Turfgrass requires one inch of water per week in order to grow and thrive. There are few grasses that will get along with less than that so you if you are unable to provide a deep soaking once or twice a week, you may want to reconsider having lawn at all. Turf under stress is more prone to insect and disease problems so eventually you might want to consider replacing your lawn with a groundcover. In the meantime, most lawns are a mixture of several grasses; most commonly Kentucky bluegrass plus turftype fescue and some perennial rye. You can overseed the bare areas with fescue or perennial rye to help it green up. These grasses will have the same water requirements as your Kentucky blue. Good luck with your lawn!
