Crown thinning Bournemouth, Poole & Dorset

Too much shade, but you love the tree as it is? Crown thinning takes out selected branches from inside the crown, so more light and wind pass through while the outline stays the same.

Crown thinning: the same outline, less weight and more light.

Crown thinning in short

Crown thinning is the removal of a proportion of the smaller branches from inside a tree's crown, evenly throughout, without changing its overall size or shape. It lets more dappled light through, reduces the weight on the main limbs and the wind resistance of the crown. It is specified as a percentage, usually 10% to 20%, and never more than the tree can safely lose.

How crown thinning works

Done well, you can't see where the branches came from, only that the tree looks lighter.

Our climber works through the crown removing crossing and rubbing branches, weak or crowded shoots, and a share of the smaller branches spread evenly through the tree. The main structure is left intact.

We take care not to strip out the inside of the crown and leave leaves only at the tips, a fault sometimes called lion-tailing. That moves the weight to the ends of the branches and makes them more likely to fail.

Thinning suits broadleaf trees with dense crowns, such as sycamore, lime, oak and beech. For conifers and for trees that are simply too big, a reduction usually does more good.

Crown thinning questions

Anything not covered here? Ask us and we'll give you a straight answer.

Ask us a question

How much of a crown can be thinned?
Usually 10% to 20% of the smaller branches, evenly through the crown. Thinning more than that at once stresses the tree and can cause a flush of weak growth.
What is the difference between crown thinning and crown reduction?
Thinning removes branches from inside the crown and keeps the size the same. Reduction makes the crown smaller in height and spread. See crown reduction vs crown thinning.
Will thinning let more light into my garden?
Yes. It lets dappled light through the crown, which helps lawns and borders under and around the tree.
How often does a tree need thinning?
Typically every three to five years, depending on the species and how fast it grows.
Do I need permission to thin a tree?
Only if it has a TPO or is in a conservation area. We check and handle the application.
