Crown thinning is used for specific purposes such as to let in additional light through the canopy or reducing the sail area.
When crown thinning, we keep an even density of foliage and ensure the branches are balanced. Ideally, no more than one third of the leaf-bearing area should be removed during crown thinning and both branches and foliage should be kept as even as possible.
It is often necessary to remove weak, defective, hazardous and/or crossing branches so we take care to retain a balanced look to the tree, should this be required.
