Your March Landscape Watering Reminder

March 2023 Watering Reminder

Desert Marigold

Another great winter storm passed through Wednesday providing one-half inch of rain and more in most valley areas. Check out rainfall totals at the MC Flood Control site (click on 3 Day or 7 Day Rainfall). This should be enough rain to turn your controllers to the 'rain' or 'off' setting for a week.

March is a transitional month. While it has been very cool, upcoming warmer days will nudge Bermuda grass and other cold-sensitive plants out of dormancy. Many trees (such as mesquites, palo verdes, jacarandas, and lysilomas) may look sparse, but that's normal! They will drop their older leaves and leaf out with beautiful, fresh green foliage soon. Don’t be concerned – the leaf drop is not likely due to a watering issue.

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


Lawns

  • Summer grass (dormant Bermuda) - once every 12-14 days

  • Overseeded cool season grass (rye) - once every 7 days

Trees & shrubs on same valve

  • Desert Adapted - once every 25 days
  • High Water Use - once every 11 days

Trees

Shrubs, groundcovers & vines

Wildflower watering

  • Once every once every 8-10 days if no rain

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

Landscape Watering by the Numbers: Don’t forget our online, interactive watering guide. If you input some simple information about your landscape irrigation system, it will tell you how long to water to give your plants just the right amount with these frequencies.

Can Test (for Measuring Sprinkler Output)

Sprinkler Can Test

Sprinkler output can vary depending on your system design and water pressure. Find out how much water your sprinkler system applies with a one-time can test. Collect 6 to 8 shallow, flat-bottomed cans like tuna or cat food cans. Spread the cans around your lawn 4 to 5 feet apart (cans in photo are further apart than they appear 😉)

Then, turn on each valve or station of your sprinklers for 15 minutes. When the sprinklers turn off, measure the depth of water in each can. Record your numbers on the can test worksheet, then return to our Lawn Watering Interactive Guide (and click on the 'how much water your sprinkler system applies' tab) to calculate your sprinkler number.


**Reduce your landscape water use 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.
