Over the past weeks, we have had many opinions expressed about how desirable snow is, both for all of us humans, as well as the garden.
One major benefit of a good snow cover is snow functions as an excellent insulator of the soil. Without snow, very cold temperatures can freeze the soil deeper and deeper. This could lead to damage of root systems of trees and shrubs. The insulation effect of snow also helps protect perennials, bulbs, ground covers, and strawberry plantings from alternating freezing and thawing cycles. Without snow, milder temperatures and the sun could warm the soil surface, leading to damage from soil heaving, which can break roots and dry out plant parts. Snow also helps conserve soil moisture over the winter.
However, at the same time heavy snow can damage trees and shrubs as the weight accumulates on branches.
One final positive about snow is the enhanced visibility of some landscape plantings. Trees and shrubs with ornamental bark, such as red twig dogwood or river birches, look more brilliant.
Evergreens may look much greener, especially when a bright red cardinal is sitting in them.
For some of us, snow cover can make winter complete.
