April Landscape Watering

El Niño showers bring spring flowers, but we might not see much more rain as April through June are typically dryer as temperatures warm up. This is a great time to do an irrigation system tune-up so that your landscape will have reliable water into summer.

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 days
Overseeded cool season grass (rye) - once every 4 days 
If trees and shrubs are on the same valve:
Desert Adapted – once every 20 days
High Water Use – once every 10 days
Tree watering:
Desert Adapted – once every 24 days
High Water Use – once every 12 days
Shrub watering:
Desert Adapted – once every 16 days
High Water Use – once every 8 days
Groundcover and vine watering:
Desert Adapted – once every 16 days
High Water Use – once every 8 days
Cacti and succulent watering – once every 28 days 
Annuals watering – once every 4 days 
Native wildflowers – once every 7 days

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

**Reduce your landscape watering 30 to 50 percent by adjusting your irrigation each season.
