Kentucky bluegrass is a very common grass planted in many areas of the United States and elsewhere. It's a sunlight-loving, cool season grass with a thirst for adequate water. This grass does not set deep roots and will brown and grow dormant during drought. If you don't mind a higher water bill, you can keep a Kentucky bluegrass lawn green with a strict watering schedule.
Water newly planted Kentucky bluegrass frequently to keep it moist. The Texas Cooperative Extension recommends watering newly planted seed two to three times a day for the at least the first two weeks, tapering off after grass emerges. You’ll need to use low water pressure to keep from washing the seeds away--use a sprinkler, but on a low setting.
Place a rain gauge in your lawn to measure how much water the grass actually receives, whether it be from rain or sprinkler.
Use a sprinkler, with regular water pressure, when necessary for established grass. Kentucky bluegrass requires up to 2 inches of water per week to stay green during warm weather, according to the Texas Cooperative Extension, and at least 1 inch should be supplied during a single watering to help the lawn establish good, deep roots. Avoid shallow, frequent watering, opting instead for deep watering once or twice a week.
Things You Will Need
- Rain (water) gauge
- According to American-Lawns, Kentucky bluegrass enjoys a lot of regular watering but can survive periods of drought by going dormant. The University of Nebraska-Lincoln advises that giving dormant bluegrass lawn at least 1/2 inch of water every two weeks will keep it alive (although not green).
- If you allow the grass to grow dormant, treat it with extra care. The University of Nebraska-Lincoln warns that heavy foot traffic and other wear to the dormant grass can cause permanent damage.
