Question: can zoysia grass be overwatered?
Answer: Frequent watering can be too much of a good thing for a lawn. For example, warm-season grasses, such as Bermuda and zoysia grasses, need 1/2 inch to 3/4 inch of water as infrequently as every one to three weeks. ... Too much water interferes with healthy grass growth and makes the lawn susceptible to pests and diseases.
