Your July Landscape Watering Reminder

July 2025 Watering Reminder

Citrus Tree Wilting

This is no time to have irrigation problems! We’re in the thick of it – with a string of 110°+ days behind us and the tease of monsoon activity fading. Your landscape is officially on sprinkler or drip system life support as we push through the hottest stretch of the year.

June and early July are when plants need water the most. Long days, high daytime and nighttime temps, and intense sunlight all contribute to rapid moisture loss from both soil and plants. Even well-watered landscapes may show signs of stress as plants struggle to adapt to the extreme heat.

Some cloud cover, higher dewpoints, and a bump in humidity may feel hotter to us – but it actually helps plants by reducing water loss. Still, as with most monsoon seasons, rainfall remains unpredictable and hit-or-miss (learn more below).

Stay vigilant. Keep your irrigation system in top shape and watch for signs of heat stress. Your plants are counting on you to get them through it!

Recommendations below are for plants that are established in the landscape (in the ground about two years).


Lawns

  • Warm season grass (Bermuda) - once every 3 days

  • Overseeded cool season grass (rye) - grass dies out

Trees & shrubs on same valve

  • Desert Adapted - once every 14 days
  • High Water Use - once every 7 days

Trees

  • Desert Adapted - once every 16 days
  • High Water Use - once every 8 days

Shrubs, groundcovers & vines

  • Desert Adapted - once every 12 days
  • High Water Use - once every 5 days

Cacti and succulent watering

  • Once every 18-20 days

Annuals & vegetable watering

  • Once every 1-3 days

Note: These recommendations are a general guideline only and may need to be modified for your specific site conditions.

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.

Mesa Wins National Water Conservation Challenge

Mesa Wins Water Conservation Challenge

BRAVO EVERYONE!! 👏🏻 Thanks to you, Mesa was named a national winner in the 2025 Wyland Mayor’s Challenge for Water Conservation, placing first among cities in its population category. Competing against cities like Minneapolis, Tucson, Santa Ana, and Atlanta, Mesa had the highest percentage of residents take the pledge – committing to save over 22 million gallons of water, along with actions that reduce energy use, waste, and emissions. Mesa was one of just five cities nationwide recognized for top participation, reflecting our strong culture of sustainability and shared commitment to water stewardship. Other winning cities in their respective population categories include Laguna Beach, CA; Union City, NJ; Jersey City, NJ; and Columbus, OH. Learn more

Even more exciting... as one of the five national winners, all Mesa residents who took the Mayor’s Pledge in April are now entered into a grand prize drawing for up to $3,000 toward their home utility bill! Woo--hoo! 🎉


Rainwater Harvesting

Rain Chain

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:


Monsoon Melodies

Something Fun! Monsoon Melodies

Monsoons are music to our ears! That's why our Water – Use It Wisely outreach campaign curated a special playlist on Spotify of rain-themed songs. Yes, it's still a bit dry outside, but the playlist includes classics like I Wish It Would Rain by the Temptations and No Rain by Blind Melon. Check it out and get in the rainy day spirit!

It's Swimming Pool Season

High water bill? Well, if you have a pool, over 2,500 gallons just evaporated in one month! POOF!

Swimming pool

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?

Irrigation drip emitter

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 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!
