Living in London or Southwestern Ontario? You might be wondering when to tackle those overgrown branches. The ideal time to prune most trees is late winter to early spring (February through early April).
Pruning while your trees are dormant minimizes stress and accelerates healing when the warmer weather hits. Crucially, winter pruning protects your trees from local threats like Oak Wilt and Dutch Elm Disease, which are more active during the growing season.
5 Warning Signs Your Tree Needs Immediate Pruning

Trees in Southwestern Ontario face tough conditions, from ice storms in Exeter to high winds off the lake in Grand Bend. Ignoring structural issues can lead to expensive property damage.
Check your trees for these five red flags:
"Widow Makers" (Dead or Hanging Limbs):Â These broken branches are often left behind by winter storms. They pose a serious safety risk to your family and home and need removal immediately.
Rubbing Branches:Â When limbs cross and grind against one another, they strip away protective bark. This open wound invites pests and fungi common in Middlesex County.
Structural Encroachment:Â Are branches scraping your roof or tangling with power lines in St. Thomas? This is a fire hazard and a pathway for pests to enter your home.
Overcrowded Canopy:Â A dense tree blocks sunlight and airflow. Thinning the canopy prevents the damp conditions where fungal diseases thrive during humid Ontario summers.
Suckers and Water Sprouts:Â These fast-growing, weak shoots near the base steal energy from the healthy parts of the tree.
DIY vs. Professional Arborists: When to Call for Help
Trimming a small hedge is a great weekend project. However, large tree work carries significant risks. In the London area, follow this simple rule: If you need a ladder or a chainsaw above shoulder height, call a professional.
Improper pruning can permanently damage your tree or cause severe injury. If your tree is leaning, close to utility lines, or showing signs of internal rot, trust the certified team at Out on a Limb Tree Experts. We use specialized equipment from Bucket Trucks for high-reach limbs to Cabling & Bracing for structural support—to handle the job safely.
