Question: How often should I water my lawn?
Answer: There is no good answer to that question. Turf needs to be allowed to dry somewhat between waterings. That encourages the grass to develop deeper, stronger roots. Frequency will vary greatly in the winter, spring and fall due to variations in the weather. However, during the hot summer weather aim to water no more often than every 4 or 5 days (3 or 4 days if temperatures exceed 100 degrees). Water heavily enough that the grass doesn't dry out any sooner than that. Leave sprinkler systems in the "Manual" mode so that they don't run when they're not needed.
