September days can have widely varying temperatures, with some days getting into the 90s, but we can count on nights being longer and cooler. This means that plants do not need to be watered as often. Ramping down how often you water your yard is a great way to save money on your water bill and keep plants happy.
After spending the summer putting energy into growing leaves, flowers, and fruit, plants use the fall to store water and energy in their roots for winter survival and spring growth. Proper watering supports this activity.
Ramping down your irrigation does not mean you should stop watering altogether. If you have a lawn, cut back to two days per week. Cut back to two times a month for mature trees (4 times a month for younger trees).
See our Fall Season Watering Recommendations for general recommendations on how often and how much to water different plant types.
