The heat is here! And this time, we’re talking more than one way. June means our temperatures will start to climb to over 100 degree days. But if you haven’t heard, on May 18, Mesa enacted the first step in our plan to deal with water shortages. While there are currently no mandatory water reductions or restrictions, we ask guests to take voluntary steps to conserve water in any way possible. Efficiently watering your landscape is one of the best and easiest ways to do this. See our June watering recommendations below.
How do we balance water scarcity with the water needs of our landscape?
We must keep in mind that trees, shrubs and our landscape plants provide multiple benefits to our environment. Trees help shade and cool our neighborhoods, as well as filter harmful pollutants from the air and reduce noise pollution. They also play a central role in the water cycle by absorbing water from the ground and returning water vapor to the atmosphere. Without trees, our desert climate can become much hotter and drier. This is just one more reason why we recommend planting desert-adapted plants and trees in our landscapes, as they can survive on rainfall after establishment.
Monsoon Season: Speaking of the water cycle, forecasts indicate that we could have a very wet and active monsoon season this summer. If so, this will be a great opportunity to turn off irrigation systems if rainfall provides enough water for your landscape. If you get at least a half inch of rain, you can skip a watering cycle. The monsoon season runs from June 15 to September 30, so be prepared for wind, dust and power outages…and hope for the remarkable rainfall forecast.
The recommendations below are for plants that are established in the landscape (in the ground about two years).
- Warm season grass (Bermuda) – once every 3 days
- Overseeded cool season grass (rye) – grass dies
Trees and shrubs on the same valve
- Adapted desert – once every 14 days
- High water consumption – once every 7 days
- Adapted desert – once every 16 days
- High water consumption – once every 8 days
Shrubs, ground covers and vines
- Adapted desert – once every 12 days
- High water consumption – once every 5 days
Watering cacti and succulents
Annuals and watering vegetables
- Spring wildflowers die, go to seed and can be uprooted
To note: These recommendations are a general guideline only and may need to be modified for your specific site conditions.
Landscape irrigation in numbers Don’t forget our online interactive watering guide. If you enter some simple information about your landscape irrigation system, it will tell you how long to water to give your plants the right amount with those frequencies.
