Your June Landscape Watering Reminder
The party’s over! Temps will be 105-degrees and above starting Saturday. I hope your irrigation system is in working order. Be sure to water deeply at each irrigation for greatest efficiency. Are you seeing fruit drop on your citrus? Learn more below.
Did you know that starting in 2008, the National Weather Service defined our monsoon season to begin June 15 and end September 30? If you didn’t live here prior to 2008, you missed the methodical but quirky way we used to determine the start of the season. Learn more at AZ monsoon trivia. The point is, that you should be ready for wind, dust and power outages... and let's hope for some rainfall.

LAWN WATERING: If you're watering every day, you're watering too much! Our watering recommendations are based on science from the University of Arizona. It is healthier for grass if you apply .75 inch (3/4 inch) of water each time you irrigate to wet the root zone to a depth of about 8 inches. This encourages roots to go deeper into the soil where they are better protected from hot, dry winds. With this amount of water, your grass will only need watering once every 3 days in the hottest part of summer, and less often as we get into the fall months. How do you know if you're applying 3/4" of water? I thought you'd never ask! See pages 7 and 8 of our watering guide. Once you've found your run time for your specific system, you only need to change your frequency of watering through the year.
**Reduce your landscape watering 30 to 50 percent by adjusting your irrigation each season.** "Landscape Watering by the Numbers: A Guide for the Arizona Desert" will help you determine how much water to apply and how long to run your system.
