This is no time to have irrigation problems! We have brutally hot 110+ temps and little monsoon activity happening so far. Your plants are on sprinkler or drip system 'life support' as we get through the next few weeks.
The water needs of plants are the greatest in June and early July. Long days, high temps (day and night), and intense sunlight all mean greater water loss from soil and plants. Even adequately watered plants may show signs of stress as they adapt to the extreme heat.
If we get more cloud cover and higher dewpoints and humidity like we had recently, that will help. It might feel hotter to us, but it is easier on plants. As is typical of our summer monsoons, the rainfall can be hit or miss. Learn more below.

Landscape Watering by the Numbers: Don’t forget our online, interactive watering guide. If you input some simple information about your landscape irrigation system, it will tell you how long to water to give your plants just the right amount with these frequencies.
Rainwater Harvesting
Since summer monsoon storms can be localized, shop for a rain gauge if you don't have one, or empty the dust out if you do. 😉
If you get at least 1/2" of rain you can skip an irrigation cycle. If you are not sure how much fell in your yard (and you didn't buy a rain gauge yet), visit rainlog.org or Maricopa County Flood Control Rainfall Map. Turning off controllers during rain events is a great way to save water and help out with the drought.
Don’t miss out on using this clean, salt-free source of water that contains many beneficial ingredients for plants. Check out our resources below for harvesting rainwater from our monsoon storms:

It's Swimming Pool Season
Well, if you have a pool, over 2,500 gallons just evaporated in one month! POOF!
|
Thinking of installing or removing a pool??
There is a great new resource page available developed by water providers in the Tucson area. You can learn about what resources (water, energy, maintenance) it takes to have a pool. There is also advice on pool removal benefits and options to do so. Learn more!
How long should you run your irrigation?
Each time you water, be sure to water deeply. About 1 foot for groundcover, 2 feet for shrubs, and 3 feet for trees. How long is that? See our interactive landscape watering guide for a quick and easy way to determine your run times. For example, a 2-foot diameter shrub would need about 4 gallons of water each time you water. If you have a 1-gallon per hour emitter on that shrub, your run time would be 4 hours!
