I know some gardeners are getting very anxious to get back into the garden already this year. They would have a tough time though, because the garden is covered with about two feet of snow. This is called snowpack, and it is not a bad thing.

Snowpack acts as a crucial protective blanket for gardens, insulating soil to prevent extreme temperature swings and harmful frost heave that can damage plant roots. As the snow melts, it provides slow-release moisture into the soil, prevents drying winds from harming perennials, and deposits nitrogen and essential nutrients into the ground. 

Here is why snowpack is beneficial for your garden:

  • Insulation: Snow keeps the soil temperature more stable, preventing deep freezing that can damage roots or bulbs.
  • Preventing Frost Heave: By keeping soil temperatures consistent, it stops the freeze and thaw cycle that pushes plants out of the ground.
  • Moisture Reservoir: As snow melts, it provides a slow, deep watering to the soil, which is often more effective than rapid spring rains.
  • Poor Man's Fertilizer: Snow captures nitrogen, sulfur, and other nutrients from the atmosphere as it falls, depositing them into the soil when it melts.
  • Protection from Elements: It protects plants from drying winter winds and damaging sun.
  • Pest Control: Deep, consistent snow cover can help kill overwintering insects and pests.
