Your May Landscape Watering Reminder

Post Date:05/05/2017 12:51 PM

On Wednesday, we hit our first triple digit temps of the year. Even though we’ll get a nice cool down over the weekend, it looks like we’ll be climbing back up by the end of next week. Mid-May through October is considered our summer season. Bermuda grass and many landscape plants may look a little stressed as they transition from our spring to summer temperatures.

Humidity levels are low and there are lots of windy days. What this means for plants is a lot of moisture gets lost from the soil surface and through the leaves. Make sure you are giving plants a good drink of water, especially during or after a dry, windy day (don’t use sprinklers during windy days).

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

Lawn watering

  • Summer grass (Bermuda) – once every 4-5 days
  • Overseeded cool season grass (rye) – once every 3 days

If trees and shrubs are on the same valve

  • Desert Adapted – once every 17 days
  • High Water Use – once every 8 days

Tree watering

  • Desert Adapted – once every 20 days
  • High Water Use – once every 10 days

Shrub watering

  • Desert Adapted – once every 14 days
  • High Water Use – once every 6 days

Groundcover and vine watering

  • Desert Adapted – once every 14 days
  • High Water Use – once every 6 days

Cacti and succulent watering – once every 24 days

Annuals watering – once every 3-4 days

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

Have you ever performed the sprinkler can test for your lawn sprinklers? If not, it's a lot of fun and the results will tell you just how long you need to water each time you irrigate. Find instructions on page 5 of Landscape Watering by the Numbers.

After your audit, if you decide it’s time to replace some of your sprinkler heads, consider using 'rotating stream sprinkler heads' which apply water much more efficiently and are particularly good for slopes to reduce runoff. Learn more about this new technology at the Water Use It Wisely site.

Denver Water has a hilarious (but very instructional) video about the three Checks to make before firing up your sprinkler system!

Just because Arbor Day has passed, doesn't mean you stop taking care of your trees. Find resources on planting, pruning, selecting a tree care professional and more on our Arbor Day page.

**Reduce your landscape watering 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.
