Preparing for Winter Series #1: Watering Your Lawn & Landscape
How much to water in the fall? Not at all!
Turn off your irrigation! Your lawn and landscape does not need supplemental water in typically cool, moist, fall weather. This is the time to encourage roots to grow deep and strong: resilient and ready for hot and dry weather next summer.
However, as a final treat to your plants, and their roots, before heading into the long cold winter, you might need to give them a long deep drink, making sure there is plenty of moisture way down in the soil before your irrigation system is shut down for the winter. How to do that?
First, test to see how deep your moisture lies (need a moisture meter?). It needs to be at least 6” deep. If it is wet, all is well. If it is dry down there, water away. It could mean for hours: think the equivalent of a day or two of rain. Consider dividing watering into two consecutive days to allow water to penetrate, especially in heavier soils.
