December's Watering Reminder

From the City of Mesa:

Yes, some areas did get a trace of rain overnight on December 5, otherwise most areas last saw rain on August 23. It’s dry, dry, dry, and humidity has dropped and wind has picked up. This can also dry out your plants. Point is, while plant usage is at its lowest point in December, make sure you’re still irrigating, as your plants will fare cold temps and frosts better if hydrated.

Our typical first frost is around December 12, though we're already seeing unseasonably warm temperatures. But, it's still good to be prepared for a cold snap. Learn how to protect your plants from frost in a University of Arizona publication. For frost warning advisories, visit the National Weather Service Phoenix Web site and click on "Read watches, warnings and advisories."

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

Lawn watering
Summer grass (dormant Bermuda) - once every 21-30 days
Overseeded cool season grass (rye) - once every 10-14 days.

If trees and shrubs are on the same valve
Desert Adapted - once every 35 days
High Water Use - once every 18 days

Tree watering
Desert Adapted - once every 45 days
High Water Use - once every 21 days

Shrub, groundcover & vine watering
Desert Adapted - once every 28 days
High Water Use - once every 14 days

Cacti and succulent watering - if needed

Annuals watering - once every 7-10 days

Wildflower watering - once every 10-15 days

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