Temperatures have consistently been below freezing and periodic snowstorms are spinning through the area. Ladies and Gentlemen, we are in the heart of winter! Looking out your window, you may be wondering how all this cold weather and heavy snow cover could be good for your garden.
The truth is snow is beneficial for your landscape! It acts as a winter mulch, providing insulation from the harsh winds and minimizing the effects of the freeze thaw cycle. Snowpack slows the deep, subgrade soil freezes and reduces the chances that perennials you divided in the fall will heave and expose their roots to the elements. Once temperatures warm and the sun begins to shine, the snow melts and our plants use that water to jump start the spring growing season! Snowpack is a good thing!
OK, so snow on the ground is great, but what about the snow that is bending my arborvitae or weighing my boxwood branches down to the ground? While heavy snow is not ideal, plants that we use in our gardens have evolved over time and have adapted to the weighty snows that winter may bring. While your shrubs may look stressed, the snow will eventually melt from their bent branches and they will reclaim the form you are accustomed to seeing. However, if you can’t help yourself and you feel you have to remove the snow and “save your plants”, do so slowly and when temperatures are not bitterly cold. The colder the air temperature, the more susceptible branches are to snapping, thus negating your attempts to “help” your shrubs. Whatever you do, do not shake the snow from the branches!
As snowfalls continue to roll through the area, please take caution to not stack snow on top of or around your plant material. Large piles of snow resting on your plants add extra weight and increase the likelihood of winter damage. Those snow mounds can also allow resource starved rabbits and deer to reach higher into the plant possibly causing more foliage damage than during the growing season.
As our winter persists, enjoy the changing seasons, remember that your shrubs will survive and embrace all the beauty that winter has to offer!
