It’s been a dry fall and early winter throughout most of Colorado — in spite of the recent snow (that’s rapidly disappearing as I write this). Little precipitation, combined with windy, sunny and warm days, is a pretty good recipe for some winter turf injury (aka “winterkill”). Throw in some alternating extreme cold with the warm days and things get potentially worse for turf, trees and shrubs in our landscapes. But not all “winterkill” is the same when it comes to turf. Turf, trees, shrubs and other landscape plants may not be growing and, thus, using much water during the winter. But when it’s dry, windy, sunny and humidity is low, our landscape plants are losing water. When we don’t receive enough snow to provide periods of snow cover during the winter and plants aren’t mulched (like turf), are young and not fully established, or have poorly developed root systems, winter watering can be essential for preventing winter injury or death. When weather allows (above freezing for a day or two), run a hose and sprinkler out to the drier parts of your landscape (especially south- and west-facing parts of your landscape), to new sod, trees and shrubs, and to areas where you have experienced winter injury in the past (perhaps from turf mites). Apply enough water to moisten the crowns of the turf plants and to get some water into the root zone of new trees and shrubs. The goal isn’t deep watering, but rather to prevent desiccation of crowns and young root systems.
