Your February Landscape Watering Reminder

Post Date:02/01/2018 11:00 AM

Conditions continue to be mild (even warm) but dry, with little rainfall this season. The beautiful 70-degree days are perfect for some irrigation repairs or upgrades. For trees, moving emitters out to the drip line as they grow or adding more emitters is a good idea. It’s also a perfect time to check emitters to ensure that they are working properly and that you don’t have any leaks in the system. When you’re testing the irrigation, you’ll be giving added moisture to your plants. Get our irrigation maintenance checklist at

Recommendations below are for plants that are established in the landscape (in the ground about 2 years).

Lawn watering:

Summer grass (Bermuda) - once every 21 days
Overseeded cool season grass (rye) – once every 7-9 days

If trees and shrubs are on the same valve:

Desert Adapted - once every 28 days
High Water Use - once every 12 days

Tree watering:

Desert Adapted - once every 36 days
High Water Use - once every 14 days

Shrub watering:

Desert Adapted - once every 21 days
High Water Use - once every 10 days

Groundcover and vine watering:

Desert Adapted - once every 21 days
High Water Use - once every 10 days

Cacti and succulent watering – once every 28 days

Annuals watering - once every 6-9 days

Wildflower watering – once every 9-12 days

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

**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.

AT LEAST ONE-HALF INCH OF RAIN MEANS IT'S TIME TO TURN YOUR IRRIGATION OFF!  Any time you get one-half inch of rain or more, use the 'off', 'stop', or 'rain' setting on your controller or timer to stop the watering cycle without disturbing your programs. Skip an irrigation cycle or two and keep an eye on your landscape to determine when you need to turn the controller back on. Visit to see rainfall totals in your neighborhood.
