Crown Reduction
Crown reduction is used to reduce the height and/or spread of the crown of a tree by the removal of the ends of branches whilst maintaining the tree's natural shape as far as possible.
Why have it done?
Crown reduction is often used when a tree has grown too large for its permitted space. It is preferred to topping because it results in a more natural appearance, increases the time before pruning is needed again and minimises stress.
This type of pruning can be completed for a number of reasons to achieve a range of management objectives, from purely aesthetic when used to shape an entire canopy, to the reduction of one limb where excessive weight may threaten failure.
