What Happens to Trees in Winter & Why It Matters

/in /by

When winter arrives, homeowners think trees are “asleep” and won’t need any attention until the spring. Although it is true that trees enter a period of dormancy during the colder months, a lot is still happening beneath the surface. Understanding how trees behave during the winter can help you protect your trees and even set your landscape up for long-term health.

Trees Enter Dormancy, But They’re Not Inactive

During winter, most trees go dormant as a survival mechanism. Dormancy allows trees to conserve energy by slowing growth and metabolic activity. Leaves fall from deciduous trees to reduce water loss and protect from freezing temperatures. Although growth pauses, trees are still alive. Roots continue to absorb nutrients when the ground isn’t frozen, and the tree is storing energy for spring. Because trees are not actively growing, winter is often less stressful for pruning and maintenance when done properly.

Cold Temperatures Change Tree Structure

As temperatures drop, wood becomes more brittle. This makes branches more sensitive and may cause them to break from the weight of the snow or even ice. Trees that are already weak,  and have things such as cracks, decay, or dead limbs, are already vulnerable during the winter. Different trees face different challenges. Heavy snow can accumulate leaves and branches, causing them to bend or snap.

Why Some Trees Fail During The Winter

Tree failures during the winter are not that common. In most cases, they result from pre-existing issues that only worsen by cold weather. Common causes may include:

  • Dead or dying branches.
  • Internal decay or hollow trunks.
  • Poor structural growth.
  • Trees planted too close to structures.

Without leaves, these problems are often easier to spot during the winter. Bare branches allow one to clearly see a tree’s structure and identify risks that might be hidden during the growing season.

Winter Is an Ideal Time for Preventive Care

Because trees are dormant, winter is actually one of the best times for professional tree care. Pruning during this season minimizes stress on the tree and reduces the risk of spreading disease or attracting pests. It also encourages a healthier, more controlled growth in the spring. Winter is also a great time to plan or perform tree removals. Frozen ground helps reduce damage to surrounding lawns and landscaping, and scheduling is often more flexible than during peak spring and summer months.

Why This Matters for Homeowners

Understanding what happens to trees in winter helps homeowners make informed decisions about safety and maintenance. Proactive care can prevent costly property damage, reduce damage after storms, and extend the life of your trees.
