Watering Guidelines for July

July's reminder from the City of Mesa, the web version can be found at  www.mesaaz.gov/conservation/LWR.aspx

July started with high temperatures and heat advisories but increased humidity is easier on plants.

Rains have been hit or miss. Shop for a rain gauge if you don't have one (empty the dust out if you do) as these storms are localized. Turn your irrigation off if you get at least 1/2" of rain. See our tips below to
learn about grass removal and rainwater harvesting - both will save you water!

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 days
        Overseeded cool season grass (rye) – grass dies out

If trees and shrubs are on the same valve:
        Desert Adapted - once every 14 days
        High Water Use - once every 7 days

Tree watering:
        Desert Adapted - once every 16 days
        High Water Use - once every 8 days

Shrub watering:
        Desert Adapted - once every 12 days
        High Water Use - once every 5 days

Groundcover and vine watering:
        Desert Adapted - once every 12 days
        High Water Use - once every 4 days

Cacti and succulent watering - once every 21 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.
