Your October Landscape Watering Reminder

Post Date:10/02/2017 2:04 PM

There’s been no rainfall since late August, but cooler temps have helped many plants recover from summer’s sizzle. Conditions will be flirting with 100-degree temps this weekend, but should be cooling back down. If you haven’t adjusted your irrigation clock/timer in a while, now is the time to do so. Water needs for plants are about half as much as they were in June. Check out these step-by-step instructions to reprogram your timer to the watering schedule suggested below.

Fall is such a great time to plant, (see bonus tips below about plant sales and more), and to sow your Sonoran Desert wildflower seeds for spring bloom. Call us at 480-644-3306 or email us for a free seed packet!
