The Q&A Archives: Watering In Winter

Question: We live where we average 5-6 inches of rain per year. I have lots of lawn, trees, bulbs, and regular plants. We have Tule fog for several months. My husband thinks no watering is necessary because of the fog. Can use please explain about proper watering in these conditions?

Answer: Shrubs, trees and lawns need about one inch of water per week when they're actively growing, regardless of fog. Most plants slow their rates of growth during the winter months and will require less water than in the summer months, but turfgrass and many shrubs and trees will continue to grow as long as the soil temperature is above 40 degrees. If your plants look healthy, and they've been in the landscape for more than one year, regular watering probably isn't necessary during the winter months. If the leaves begin to wilt, or the plants look stressed, supply water once every week to 10 days regardless of the time of year.
