How to Assess Winter Damage on Your Trees: What to Look For

As winter fades and spring emerges, it’s important to assess how your trees have weathered the cold months. Ice, snow, strong winds, and fluctuating temperatures can all take a toll on trees, causing damage that may not be immediately visible. Identifying and addressing these issues early can help prevent further problems and promote healthy growth as the warmer season arrives. Here’s what to look for when inspecting your trees for winter damage and how to take action.

Signs of Winter Tree Damage

Broken or Hanging Branches – Winter storms can leave behind broken or partially detached branches, which pose a safety risk. Be on the lookout for:

  • Large limbs that have snapped under the weight of snow and ice
  • Branches that appear weak, cracked, or dangling
  • Jagged or torn bark from fallen limbs

If you see broken branches, they should be carefully pruned or removed to prevent further stress on the tree and reduce the risk of falling hazards.

Cracks in the Bark (Frost Cracks) – During winter, rapid temperature changes can cause bark to expand and contract, leading to vertical splits known as frost cracks. These often appear on the trunk or large limbs and can weaken the tree over time. Look for:

  • Long, deep cracks running along the bark
  • Peeling bark or open wounds
  • Areas of discoloration or sunken spots

Minor cracks may heal naturally, but deep splits should be monitored to prevent decay or pest infestation.

Trees Leaning or Uprooted – The combination of wet soil, heavy snow, and high winds can loosen a tree’s root system, causing it to tilt. If you notice:

  • A tree leaning at a new or sharper angle
  • Exposed roots or disturbed soil at the base
  • A tree that seems unstable in the ground

It’s best to have a professional evaluate the tree. A leaning tree could be at risk of falling, especially during spring storms.

Dead or Damaged Branches – Some branches may not survive the winter, even if they aren’t broken. A simple test to check for deadwood is the scratch test:

  • Scratch the bark—if the inner layer is green, the branch is alive; if it’s brown and brittle, it’s likely dead.
  • Look for branches that have no buds or are missing bark.
  • Dead branches may also show signs of decay, such as fungi growth.

Pruning dead branches in early spring encourages healthy new growth and prevents decay from spreading.

Salt Damage from Roads & Sidewalks – If your trees are located near roads, driveways, or sidewalks, they may have been exposed to road salt or de-icing chemicals during winter. Signs of salt damage include:

  • Brown or scorched-looking leaves and needles
  • Stunted or weak new growth in spring
  • White residue near the base of the tree

To help trees recover, thoroughly rinse the soil with water in early spring to wash away excess salt and apply fresh mulch to protect the roots.

Winter Burn on Evergreens – Evergreens are especially vulnerable to winter burn, a condition caused by dry winter winds that pull moisture from the needles. Symptoms include:

  • Browning or yellowing needles, often on one side
  • Patchy or uneven needle loss
  • Foliage looking dry or scorched

Watering deeply in early spring and applying a slow-release fertilizer can help evergreens regain their health.

Pest & Disease Warning Signs – Weakened trees are more susceptible to pests and diseases. As you assess winter damage, check for:

  • Small holes in the bark (indicating insect activity)
  • Unusual growths, cankers, or fungal infections
  • Sticky residue or black mold (caused by sap-sucking insects)

Early detection of tree pests and diseases can prevent further damage. If you spot signs of infestation, professional treatment may be needed.
