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."
