4 Big Ways Snow Can Benefit the Garden
Snow insulates plants and trees
Snow cover protects plants from harsh, drying winter winds which can freeze the ground and damage the root systems of shrubs and trees. In fact, without snow, cold weather could freeze the soil and further damage root systems in trees. You could say that snow it acts like an insulating blanket, and in wintertime, who doesn’t want an insulating blanket to stay warm? It works by trapping pockets of air that hold in heat for the plants. Mother Nature is a wondrous thing!
Beneath one foot of snow, the soil and the organisms within it are protected from changes in the air temperature above the snow surface. The moist surface of snow influences how much heat and moisture circulate between the ground and the atmosphere. For every inch of snow, you get 1 R-value of insulation. (R-value is a way to measure insulation). Although the R-value can vary with the type of snow, you can get a good idea of how insulating this really is to the garden.
Snow adds nutrients to the soil in the spring
The University of New Hampshire’s Department of Natural Sciences states that snow contains nutrients that penetrate into the soil and does some good for the plants that will grow in that soil later on in the year. Nutrients include nitrogen (most prevalent), along with some sulfur and other trace elements. Studies even claim there are more of these nutrients bound up in snow than in the corresponding amount of rain.
