As the temperatures cool down this month, our plants, trees and grasses start to transition. Help this natural process of dormancy by reducing how much and how frequently you water your landscape.

For your sprinkler system, begin by reducing run times or dropping a day off your weekly watering schedule. Then, as chilly mornings turn into colder days, you can slow down watering your landscape even more, to once a week or less. You’ll notice this transition, as grasses and plants grow more slowly. This is a solid clue that your yard is moving into dormancy. At this phase, less water near your root systems is better than too much!

When should your sprinkler system be completely shut down?

When temperatures are sufficiently cold, your grass will stop growing. This means your lawn is dormant and your sprinkler system can be shut off for the winter. And don’t forget to drain and disconnect all outdoor hoses and winterize your sprinkler system before the first hard freeze. TMWA has created a short video to guide you through the process at or visit to find more tips.
