It’s summer and we want to keep the grass green so what do you do? Possibly one of the most asked questions this time of the year, “How long do I run my sprinkler system?” There are several factors that go into answering this question. What kind of heads do you have, how much grass is in the area, is it on a hill, has it been raining, etc. The biggest thing to remember is don’t water everyday for short periods of time. Water long and deep.
