The term crown thinning refers to the removal of smaller branches that are usually situated towards the outer crown of the tree. This practice helps to create uniformity and can reduce excess weight, but does not change the shape or size of the tree. As a guide, no more than 30% should be removed at any one time. Once the crown has been thinned once, it is likely that large amounts of *epicormic fast growth will occur, that will need to managed again in time.
*epicormic – New growth that arises from dormant or new buds directly from main stems/trunks or branches.
