The Silver Lining of a Cold & Snowy Winter

This has been one of the coldest winters in recent memory, and the snow has lingered on the ground for an extended period. While it may feel harsh to us, snow cover provides significant benefits for trees.

One of the most important benefits is root protection. Snow acts like nature’s insulating blanket, moderating soil temperatures and reducing freeze–thaw cycles. Without this protection, soil can repeatedly expand and contract, causing “frost heaving,” where roots are pushed upward and exposed to the elements. Snow also helps prevent roots from drying out during cold, windy conditions.

As snow gradually melts, it seeps slowly into the soil rather than running off the surface. This steady infiltration improves soil moisture and helps maintain healthy groundwater levels. Snow is sometimes called “poor man’s fertilizer” because it captures small amounts of nitrogen from the atmosphere as it falls. As it melts, those nutrients are slowly released into the root zone, giving trees a gentle boost.

Additionally, prolonged snow cover can improve soil structure. It allows soil particles to settle and organic matter to continue breaking down, supporting better aeration and drainage over time. Because of the consistent, gentle snow cover we’ve had for much of this winter, I’m optimistic that our trees will respond with strong, vigorous growth this spring. When warmer weather finally arrives, we may see landscapes that are especially healthy and resilient thanks to this season’s protective blanket of snow.

Sincerely,
