How do I prune my trees for Winter?
Winter Tree-Care for Safety and Power Line Protection
Overview
Freezing temperatures, ice, and high winds can turn neglected or unhealthy trees into hazards, especially near power lines. Proactive pruning and maintenance now can help prevent limbs or trees from falling and causing outages or safety risks. Below is a guide for homeowners on how to inspect, prune, and care for trees during the colder months, along with links to trusted resources.
Why Winter Tree Maintenance Matters
Cold, ice, and wind can stress trees, roots may freeze, limbs can crack, and weak trunks may topple. Even mild Texas winters can damage trees, according to the Texas A&M Forest Service. Unmaintained or dead trees near power lines pose serious risks, including outages and fire hazards. Regular care keeps trees healthy and protects utility infrastructure.
When to Prune
• Mid-winter is best for major pruning since trees are dormant and recover faster
• Avoid pruning immediately after a freeze or during extreme cold
• Don’t prune oaks from February through June to prevent Oak Wilt
How to Prune
• Remove dead, diseased, or weak branches, especially near power lines.
• Make clean cuts just outside the branch collar.
• Maintain several feet of clearance from power lines, contact professionals if unsure.
• Never prune limbs directly touching utility lines.
Other Winter Tree Care Tips
• Inspect for cracks, cavities, or crossing limbs.
• Keep soil moist before freezes and apply 2–3 inches of mulch, a few inches away from the trunk.
• Clear debris and avoid piling mulch against the base.
• Wait until spring to assess freeze damage before major trimming
When to Call a Professional
• Large limbs hang near power lines
• The tree leans or roots lift from the ground
• You see disease or decay
• Utility lines run close to the tree
