How Long Should You Water In July and August?

Here's a rule of thumb: July and August call for 1.5 inches in addition to our normal rainfall (which is usually pretty-much nil) in the Waco area. But your sprinkler controller thinks in time not inches. So let's convert inches to time so you can better manage your sprinkler system and your water usage.

Rotors, the heads that shoot a stream of water and the head rotates, precipitate at about .5 inches per hour. That means it takes a whopping 3 hours a week to lay down 1.5 inches of precipitation! There always seems to be a trade-off between buying water and having a beautiful stand of grass. You will make you own decision on expenses, but 3 hours for rotors is the ticket to beautiful grass during our hot summers.

Sprays, the heads that shoot water in all directions at once, precipitate at 3 times as much as Rotors. They only need to run for an hour per week to get the same 1.5 inches of precipitation.

How often? The Waco area generally has very heavy clay soil. If you run your system for too long, it just creates runoff and wastes water. Try 3 times a week at 1 hour each for Rotors and 20 minutes for sprays. If you still have runoff, cut your time in half and double your days. For example set your controller for 30 minutes for rotors and 10 minutes for sprays and run it every day but, say, Sunday.

Your grass will thank you and your checking account will wonder what happened.

Remember to change it again when the weather breaks in September.

If you don't want to constantly tweak your sprinkler's controller but want green grass and as low a water bill as possible, consider our Rainstat Controller and Weather Station. It's not for everyone but you can check it out at our site. It's like a thermostat for your yard. You set it once and forget it.
