March 2026 Watering Reminder

Desert Marigold

Whew – record highs in the low 90s wrapped up February and kicked off March! 🌡️Thankfully, a slight cooling trend is bringing us back into the 80s… just a little above normal. Normal?? What’s that? 🤔

March is a transitional month in the desert. Warmer days and nights will begin nudging Bermudagrass and other cold-sensitive plants out of dormancy. Many trees – including mesquites, palo verdes, jacarandas, and lysilomas – may look sparse right now, but that’s completely normal. They’re shedding older leaves in preparation for fresh green growth.

Don’t panic – this seasonal leaf drop is not likely a watering issue. 💧

Thinking of replacing your grass with a beautiful water-smart desert landscape? Check out the exciting update below about our Grass-to-Xeriscape Incentive program!

HOAs: We’ve got great options for you, too – including incentives up to $70,000 and free water-efficiency assessments to help determine if your common areas are being watered properly.

Can Test to Determine Your Sprinkler Run Time (Measuring Sprinkler Output) 

Can Test Photo DS

Sprinkler output can vary depending on your system design and water pressure. Find out how much water your sprinkler system applies with a one-time can test. Collect 6 to 8 shallow, flat-bottomed cans like tuna or cat food cans. Spread the cans around your lawn 4 to 5 feet apart. Then, turn on each valve or station of your sprinklers for 15 minutes. When the sprinklers turn off, measure the depth of water in each can. Write down your numbers, then visit our Lawn Watering Interactive Guide (and click on Tab 2 'know how much water your sprinkler system applies'), hit 'continue' to enter your measurements with the sliding rulers. Once all entered, hit the 'calculate' button. A screen will pop up like the one below with your sprinkler number and sprinkler run time in red. Water for that length of time every time you water. Only change the frequency as the weather changes.
