Your August Landscape Watering Reminder - RAIN!

Post Date:08/03/2017 6:09 PM

Well it’s a perfect day for your watering reminder. Hopefully, you were hit, rather than missed, with tonight’s drenching monsoon rains. Check out the Maricopa County Flood Control Rainfall Map to see what was measured near your neighborhood. Lightning can mean power outages, so make sure you’ve replaced the battery in your irrigation timer within the past year (if it has that option). Battery backup will maintain your programs during an outage. See photo below.

Are you wondering how you can capture more of the rain for your landscape plants? You’re in luck! That's the topic of our Sustainability Savings Tip this month!

These recommendations are for plants that are established in the landscape (in the ground about 2 years).


Lawn watering

  • Summer grass (Bermuda) - once every 3-4 days
  • Overseeded cool season grass (rye) - grass dies out

If trees and shrubs are on the same valve

  • Desert Adapted - once every 15 days
  • High Water Use - once every 8 days

Tree watering

  • Desert Adapted - once every 17 days
  • High Water Use - once every 9 days

Shrub watering

  • Desert Adapted - once every 13 days
  • High Water Use - once every 6 days

Groundcover and vine watering

  • Desert Adapted - once every 12 days
  • High Water Use - once every 5 days

Cacti and succulent watering - once every 22 days

Annual & vegetable watering - once every 2-3 days

Note: These recommendations are a general guideline only and may need to be modified for your specific site conditions.


+++ BONUS TIPS +++

RAINWATER is a clean, salt-free source of water that contains many beneficial ingredients for plants.

  • See our August Sustainability Savings Tip about rainwater harvesting.
  • TIP: Anytime you receive at least one-half inch of rain, use the 'off' 'stop' or 'rain' setting on your controller to stop the watering cycle without disturbing your programs.
  • See a great video from Town of Gilbert on how to shut off your timer after rainfall.
  • Did you see the ABC15 news piece about a Mesa homeowner who collects rainwater in cisterns?

CONVERTING YOUR GRASS TO XERISCAPE in summer is best because it's easiest to kill the grass when it is actively growing. Mesa has resources to help! Find out about our $500 rebate, our Top 10 reasons to take out your grass, and our brochure Good Reasons to Take Out Your Grass.

MARK YOUR CALENDAR:

  • Aug. 12, SRP Shade Tree Planting Workshop – Get two free shade trees from SRP to reduce cooling costs, improve air quality and lower the urban heat effect without using a lot of water! You’ll also learn about planting and caring for trees. RSVP because it fills up quickly. Two classes, 8 or 10 a.m. at Mesa Community College Dobson Campus. Those who attend the class can pick up their free trees on Sept. 16 to plant in their yard – a cooler time to plant. (Note: There is also a Phoenix workshop on July 29).
  • Sep. 30, Mesa Urban Garden Open House & Volunteer Fair! Want to learn more about the Mesa Urban Garden? Looking for a great place to learn more about gardening or lease a bed? Want to help contribute to your community directly with your time & talents?

HOW LONG SHOULD YOU RUN YOUR SPRINKLERS? Each time you water your grass, be sure to water long enough to wet the soil to a depth of 6-10 inches. Applying 3/4" of water will do this, but how long does that take? For many pop-up sprinklers, it takes about 20 minutes, but systems vary so much, it's best to perform a Can Test (see pg. 5). This will determine your run time that you use every time you irrigate. The adjustment you'll make through the seasons will be the frequency.

**Reduce your landscape watering 30 to 50 percent by adjusting your irrigation each season.** “Landscape Watering by the Numbers: A Guide for the Arizona Desert” will help you determine how much water to apply and how long to run your system.
