The period from the middle of May through October is considered our summer
season. Temperatures will continue to rise, and many plants will look a
little stressed as they transition into the summer period. These
recommendations are for plants that are established in the landscape (in
the ground about two 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
