Landscape Watering Reminder - August
Hot-hot-hot is the best
description for these dog days of summer. While higher
humidity makes us feel more uncomfortable, it does
decrease the water needs of plants a little.
If you've been hit, rather
than missed by the unpredictable monsoon rains, consider
yourself lucky. Many areas of the Valley have still not
received significant amounts (see tips below).
Lightning can mean power
outages. 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.
Recommendations are for plants that are established in
the landscape (in the ground about 2 years).

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
Desert Adapted -once every 17 days
High Water Use - once every 9 days
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
Annual & vegetable watering - once every 2-3 days
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. Visit the
interactive Web version or request a free copy of the booklet at
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

Where does all that water go? Did you know that a typical pool loses about 2,500
gallons to evaporation in July? Learn how to

Rainwater is a clean, salt-free source
of water that contains many beneficial ingredients for
plants. Check out our resources below for harvesting
rainwater from our monsoon storms:
Rainwater for the Landscape will help you learn
how to harvest this free resource.
Rain amounts vary greatly
across the Valley, so if you are not sure how much fell
in your yard, visit
www.rainlog.org to see what your
neighborhood weather watchers recorded. 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.
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.
