Labor Day weekend signals the start of the fall and cooling of temperatures. That means it is time to cut back on the irrigation water. If you cut back on watering days at September 1, you are going to be helping your landscape and your water bill. Because we do not know how cool or hot it is going to be, please pay attention to the needs of your plants and lawn. A1 Sprinklers recommends cutting back days not the duration. You still want to deep water.
