How to prune a tree where a branch meets the trunk
To prune a tree well, find the branch collar first. It is the slightly swollen ring where a branch meets the trunk, and the final cut sits just outside it.
Undercut
For a heavy limb, make a shallow cut from below a short distance from the trunk. This keeps the bark from tearing down the stem.
Weight cut
A second cut from the top, a little farther out, drops the limb.
Final cut
The short stub comes off just outside the collar. The collar stays whole, and the tree seals the wound from there.
Flush cut
A flush cut is wrong. It slices into the trunk and leaves a larger wound.
Long stub
A long stub is also wrong. The stub dies back slowly and rot follows it in.
Back to a side branch
This cut is right when you need to shorten a limb instead of removing it.
Learn these to judge a plan, not to climb with a saw. Texas A&M Forest Service draws each cut in its mature-tree guide, listed under Sources.
Cutting back trees hard without topping one
Tree topping cuts big limbs back to stubs to make a tree smaller, and it weakens the tree. Topping causes many fast-growing sprouts that attach weakly and can break in the next storm, so Texas Tree Tops does not top trees.

Tree topping
Topping leaves stubs, a burst of fast-growing shoots and weaker upper branches within a few seasons. Then you face the same work again.
Cut back the right way
Shorten limbs back to side branches. This keeps the tree's natural shape and reduces repeat work.
If a tree has outgrown its space, careful trimming can buy time, but large tree removal may be the final answer. Cutting it back hard every spring will not keep a large tree small.
Pruning a young tree you can reach from the ground
Choose one main trunk
If two stems compete to become the trunk, they may form a weak fork. Choose one early and shorten the other.
Keep some low limbs
Lower branches feed a thin trunk. Take them off over several years, never in one visit.
Hand pruners for thin stems
A sharp blade cuts clean. Crushed bark closes slowly.
Use long-handled cutters only on small branches
If the tool strains or crushes wood, the branch has outgrown it.
Stop when the job needs a ladder, a chainsaw or a limb you can't control as it falls.
Tree pruning checklist before anyone climbs
- Name the tree, or photograph its leaves and bark.
- Point to the exact branch and the trouble it causes.
- Note when it changed, and whether a storm came first.
- List what sits below, such as a roof, fence, pool, cars or beds.
- Measure the side gate and flag any soft ground.
- Ask how much live canopy comes off, and why.
- Agree on cleanup and who removes the cut branches before work starts.
When pruning needs a crew
Above your head
Call a crew for any cut that requires a ladder or climbing into the branches.
Over something that breaks
Limbs above a roof, fence, pool or parked car need ropes so the crew can lower them safely.
Near a power line
Stop and call the utility. Wires belong to them and their contractors.
