Crown thinning is the process of removing selected branches from the crown of the tree to improve the balance and structure of the tree, usually these are dead, weak, overlapping or duplicated branches. Crown thinning lets more light through makes the tree appear less dense, without changing the overall size or shape of the tree. Crown thinning is generally confined to deciduous broad leaf trees and helps to reduce damage that could result from strong winds. Crown thinning reduces weight on heavy limbs and helps retain the tree's natural shape. Often when discussing crown thinning, the volume of the branches to be removed will be expressed as a percentage of the whole crown.

Qualified and experienced tree surgeons will think safety first as working on trees can be dangerous.

Tree surgeons can safely remove carefully chosen branches from the crown of the tree to give more light and make the tree safer from high winds.

Tree surgery businesses or self-employed tree surgeons should be insured for at least £5million which is the accepted level of liability in the industry.
