Your October Landscape Watering Reminder

Post Date:10/02/2018

Remnants from Tropical Storm Rosa have brought major showers (over an inch in most areas) that will likely continue through Wednesday. If you haven’t already done so, use the 'off' 'stop' or 'rain' setting on your controller to stop the watering cycle without disturbing your programs.

Once it dries out and you turn your timer back on, be sure to adjust your frequencies. Remember that water needs for plants are about half as much as they were in June. Check out these step-by-step instructions to reprogram your timer to the watering schedule suggested below.

Fall is such a great time to plant, (see bonus tips below about plant sales and more), and to sow your Sonoran Desert wildflower seeds for spring bloom.

These recommendations are for plants that are established in the landscape (in the ground about 2 years).

Lawn watering

  • Summer grass (Bermuda) - once every 7-10 days
  • Overseeded cool season grass (rye) – 4x per day for 1st 7 to 10 days to germinate, then once every 3 days

If trees and shrubs are on the same valve

  • Desert Adapted - once every 21 days
  • High Water Use - once every 10 days

Tree watering

  • Desert Adapted - once every 24 days
  • High Water Use - once every 12 days

Shrub, Groundcover and Vine watering

  • Desert Adapted - once every 18 days
  • High Water Use - once every 9 days

Groundcover and vine watering

  • Desert Adapted - once every 18 days
  • High Water Use - once every 8 days

Cacti and succulent watering - once every 28 days

Annuals watering - once every 4-5 days

Wildflower watering – once every 1-2 days to germinate (only if no rains), then once every 7-10 days

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