Tree pruning explained
Quick answer: Crown reduction shortens the tree's overall size, crown thinning removes some branches to let in light, and crown lifting removes lower branches. Topping, cutting main branches back to stumps, is generally poor practice because it can damage the tree.
Tree surgeons use specific terms, and a clear brief avoids misunderstandings. Ask for the result you want, and how much will be removed.
Common terms
| Term | What it means |
|---|---|
| Crown reduction | Reducing the overall height and spread of the crown, cutting back to suitable growth points |
| Crown thinning | Removing a proportion of branches evenly to let in more light and air, without changing the overall shape |
| Crown lifting | Removing lower branches to raise the crown and give clearance |
| Deadwooding | Removing dead, dying or diseased branches |
| Pollarding | Regularly cutting back to the same point on suitable species, usually started when the tree is young |
| Topping | Cutting main branches back to stubs. Generally poor practice, because it can cause weak regrowth and decay |
Tell your tree surgeon what you want
- More light, less overhang, a clearer view or less risk?
- How much to remove, as a percentage or a target height.
- Any protected status. See permission to cut down a tree.
When to prune
Many trees can be pruned in late autumn or winter when dormant, but timing depends on the species, and you must avoid disturbing nesting birds. Ask your tree surgeon. See tree work and nesting birds.
Frequently asked questions
What is the difference between crown reduction and crown thinning?
Crown reduction shortens the tree overall; crown thinning removes some branches to let in light without changing the overall size.
Is topping a tree ever a good idea?
Generally not. It can leave weak regrowth and open the tree to decay. Ask for crown reduction or another method instead.
