When irrigating lawns, too much water is not always a good thing!! Keep tabs on how much water your lawn is getting.
Just putting the irrigation system on a routine and leaving it is not a good thing
Too much irrigation not only wastes water, it hurts your lawn.
Most warm-season perennial grasses — centipede, Bermuda, Saint Augustine and zoysia grasses — require about 1 inch of water a week.
Overwatering your lawn can result in a shallow root system and reduced drought tolerance, more diseases, more weeds, an increase in damaging insect populations, more thatch and excessive growth, and reduced tolerance to shade and soil problems
Let your lawn tell you when to water
Don’t duplicate Mother Nature’s efforts. If rain is forecast for your area, turn off your sprinkler system. Lawns only need about 1 inch of irrigation a week, so one summer thunderstorm might get the job done.
