Do You Know When to Water?


Rain has been plentiful this year, but triple-digit temps are settling in. Before you turn the sprinkler on full blast in the middle of the day, remember there is an ideal time to water.

Year-round guidelines encourage watering your landscape before 11 a.m. or after 7 p.m. if you’re using an irrigation system or sprinkler. Also, make sure the sprinklers are not overspraying onto streets or sidewalks — this is water waste and it’s always a no-no.

The best way to keep your landscape happy in the heat is to water with a hand-held nozzle or water wand. Our clay soils generally don’t allow water to soak in rapidly so watering by hand is always the best method. Plus, it’s an enjoyable, relaxing way to spend time in your yard. And your water bill will be lower for it.
