Snow cover is good for your garden, as it will insulate against any intense cold and fluctuating winter temperatures. The snow cover will help mitigate the temperature extremes and reduce the penetration of cold on days and nights when temperatures are very cold (in the teens and below). Without snow, the ground can freeze more deeply. Plants that were produced in containers and installed last year can heave out of the ground because of the freeze/thaw cycles that typically occur in late winter and early spring, if they were not mulched last fall. Think of the snow as mulch for your garden, in addition to creating a beautiful winter scene.
