Mature trees are an asset on an older Birmingham lot, and pruning is how they are kept safe to live under. The aim is to take out what is dead, broken or badly attached, and to reduce the load on limbs that extend over the house, without removing more live growth than the tree can afford. Done properly, a pruned tree does not look as though much was done to it.

  • Dead, dying and broken limbs removed from the crown
  • Branches cleared back from roofs, gutters and chimneys
  • End weight reduced on long horizontal limbs
  • Canopy raised over drives, walks and streets
  • Structural pruning for young trees

How many branches can come off?

Arborists generally keep live-wood removal to about a quarter of the canopy or less in a single year, and take less from old or stressed trees. Deadwood does not count against that limit. A request to cut a tree back by half or take all the lower limbs off in one visit should be met with a conversation about why — a competent pruner will explain what the tree can tolerate.

Topping is not pruning

Cutting the main limbs back to stubs to make a tree shorter is called topping. It removes most of the leaves the tree depends on, leaves wounds too large to seal, and triggers dense, weakly attached regrowth that is more likely to break than the limbs it replaced. If a tree has outgrown its space, the alternatives are crown reduction by a trained climber — shortening limbs back to side branches — or replacement with a smaller species.

When to prune in central Alabama

Winter dormancy is the preferred window for most trees. Structure is visible, sap flow is low and wounds begin closing with spring growth. Spring-flowering trees such as dogwood are pruned after bloom. Hazardous limbs should be removed as soon as they are noticed, whatever the month.

Common tree trimming & pruning situations in Birmingham

  • Heavy oak limbs extending over the roof
  • Deadwood overhanging a drive, deck or play area
  • Branches rubbing shingles or filling gutters
  • A canopy too low over the street or sidewalk
  • A weak fork with a visible crack or included bark

Tree Trimming & Pruning FAQs

What part of a tree should not be cut?

The top of the main leader, the branch collar and the trunk itself. Cuts are made just outside the collar — the raised ring where a branch joins — not flush with the trunk and not leaving a stub. Removing the leader or cutting into the collar exposes the tree to decay it cannot wall off.

How much does tree trimming cost?

HomeAdvisor reports a national average around $460, with most jobs from $270 to $1,800. Trees under 25 feet often cost $80 to $350; trees over 50 feet can run $300 to $1,800 or more. Work that requires climbing over a house on a sloped lot is priced toward the high end.
