Your March Landscape Watering Reminder

Post Date:03/02/2017 9:35 AM

A series of storms brought most areas a half-inch of rain or more on Tuesday. This is perfect weather for March since it is a transitional month when warm days will nudge Bermuda grass and other cold-sensitive plants out of dormancy. Having moisture available when new growth is emerging is important for a healthy start before heat sets in, and with the rains, you don’t need to provide the moisture with your irrigation system.

Many desert trees (such as mesquites, palo verdes and lysilomas) may look sparse, but it's normal! They will drop their leaves and leaf out with beautiful, fresh green leaves soon (see photo below). It is not due to a watering issue.

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

Lawn watering

  • Dormant summer grass (Bermuda) - once every 14 days
  • Overseeded cool season grass (rye) - once every 7 days

If trees and shrubs are on the same valve

  • Desert Adapted – once every 25 days
  • High Water Use – once every 12 days

Tree watering

  • Desert Adapted – once every 30 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

Annual and vegetable watering – once every 5-6 days

Native wildflowers – once every 10 days

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

How much rainfall did you get? If you don’t have a rain gauge, see what your neighborhood weather watchers are recording at You can also find rainfall information at the Maricopa County Flood Control (and click on the interactive) rainfall data maps.

Got Weeds? Weeds may compete with landscape plants for water, so this is a great time to hand pull them. It's a lot easier to pull out the entire weed, roots and all, when the soil is moist.
