Your September Landscape Watering Reminder

From the City of Mesa:

Days are getting shorter and plant water needs have already begun to decrease. How did your plants fare the months of June, July and August?
 

The monsoon rains have been a little above average so far (Sept. 30 is the official end of the season), but we also had one of our warmest summer periods on record. The record-breaker was due to high nighttime temperatures likely caused from the urban heat island. This can be stressful for plants as they need more water and/or just a break from the heat. Learn more about the likely causes of the urban heat island at http://tinyurl.com/28we769.

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

Lawn watering:
     Summer grass (Bermuda) - once every 4 or 5 days
     Overseeded cool season grass (rye) – 4x per day for
                               1st 7 to 10 days to germinate
 

If trees and shrubs are on the same valve:
     Desert Adapted - once every 18 days
     High Water Use - once every 9 days
 

Tree watering:
     Desert Adapted - once every 21 days
     High Water Use - once every 10 days
 

Shrub watering:
     Desert Adapted - once every 16 days
     High Water Use - once every 7 days
 

Groundcover and vine watering:
     Desert Adapted - once every 16 days
     High Water Use - once every 5-6 days
 

Cacti and succulent watering - once every 28 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.
