đđHappy Fourth of July! đđ
While you're celebrating with family and friends, your landscape is entering one of its toughest times of the year. Expect a string of 110°+ days ahead, making this no time for irrigation problems. Your trees, shrubs, and flowers are officially on sprinkler or drip system life support as we push through the hottest stretch of the summer.
June and early July are when plants need water the most. Long days, high daytime and nighttime temperatures, and intense sunlight all contribute to rapid moisture loss from both soil and plants. Even well-watered landscapes may show signs of stress as they work to adapt to the extreme heat.
Higher dewpoints, and a bump in humidity may feel hotter to us â but they actually help plants by reducing water loss. Still, as with most monsoon seasons, rainfall remains unpredictable and hit-or-miss (learn more below).
Your plants are counting on you to get them through the summer!Â
As we celebrate our nation's independence, it's also a good reminder that Arizona's water future depends on the choices we make every day. đ”

đ Mesa Wins National Water Conservation Challenge... Again!
 BRAVO EVERYONE!! đđ» Thanks to you, Mesa has been named a national winner in the 2026 Wyland Mayor's Challenge for Water Conservation for the second year in a row!
Although Mesa has proudly participated in the challenge for 12 years, earning back-to-back national wins is an incredible accomplishment.
Competing against cities such as Minneapolis, Tucson, Santa Ana, and Atlanta, Mesa had the highest percentage of residents take the Mayor's Pledge, committing to save more than 14 million gallons of water while also reducing energy use, waste, and emissions.
Mesa was one of just five cities nationwide recognized for top participation, reflecting our community's strong culture of sustainability and shared commitment to water stewardship. Other winners in their population categories include Laguna Beach, CA; Napa, CA; Athens, GA; and Los Angeles, CA.
Even more exciting... Because Mesa is one of the five national winners, everyone who took the Mayor's Pledge during April has been entered into a grand prize drawing for $3,000 toward their home utility bill! Woo-hoo! đ

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. đ
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.
Donât 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:

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 online landscape watering guide for a quick and easy way to determine your run times. For example, a 2-foot-diameter shrub needs about 4 gallons of water each time you irrigate. If it's watered with a 1-gallon-per-hour emitter, you'll need to run it for 4 hours to apply the correct amount.
