As much of the country braces for another round of heavy snowfall, gardeners are split on how to handle the winter weather. On one hand, a thick blanket of snow can actually be a boon for your garden beds - but it spells trouble for your trees and shrubs. The latest research from The Associated Press reveals a complex relationship between plants and the white stuff.
Snow as Natural Mulch
What this really means is that for many dormant plants, a heavy layer of snow acts as an insulating "winter mulch." As Jessica Damiano of The Gazette explains, the snow prevents the soil from repeatedly freezing and thawing, which can damage the roots, bulbs, and other underground structures of plants. As the snow melts, it also provides a gentle watering and a boost of nitrogen-rich fertilizer.
Trouble for Trees
But the same heavy, wet snow that protects your garden beds can spell disaster for trees and shrubs. Experts from North Carolina State University Extension warn that the weight of snow and ice can easily buckle or even snap the branches of evergreens and other top-heavy plants. The bigger the tree, the more vulnerable it becomes.
Preventative Measures
So what's a gardener to do? The key is to be proactive. For smaller trees and shrubs, you can try gently knocking off accumulated snow with a broom. But for larger specimens, it's best to call in a professional arborist to properly prune and support the branches. And when it comes to protecting your garden beds, The Old Farmer's Almanac recommends using breathable fabrics like burlap to create an insulating "wrap" around the plants.
The bottom line is that snow is a double-edged sword for the home gardener. While it can nurture and protect your beds, it poses a real threat to the health of your trees. By understanding the nuances and taking the right precautions, you can keep your entire landscape thriving - even in the depths of winter.
