If You Could Turn Back Time … Wait, You Can!

Daylight saving time ends Sunday, Nov. 7. Remember to adjust the clock on your irrigation controller too.

Fall brings on many changes: cool, more satisfying temperatures, less pollen and most importantly, less work in the landscape.

One of the most important changes is the turning back of all our clocks — including the one on your irrigation system controller. While you’re adjusting the controller clock, it’s also a good time to fine-tune the settings for the dormant season, aka no watering necessary.

Plants don’t need the water they did in summertime. Days are shorter, there’s less sunshine and many plants lose their leaves in preparation for dormancy. As a result, less moisture evaporates from the soil. Although plant roots continue to grow at a snail’s pace throughout winter, they don’t require a lot of hydration.

Cut run times on the controller by two thirds or use the seasonal adjust setting to decrease all the times to 20 percent or even 10 percent.

Also, make sure your controller isn’t running unnecessary programs or start times. Most in-ground sprinkler system controllers need only one start time to run an entire series of zones.

Extra or stacked times can quadruple your average water use.
