If you would like to leave the overall size of the tree as it is but would like to allow more light through we would suggest crown thinning. Crown thinning like crown reduction is a similar process of removing selected branches (usually dead, weak, overlapping and duplicated branches) from the tree crown to improve the balance and structure of the tree. Crown thinning lets more light through the branches and 'lightens' the tree making it appear less dense. This process increases airflow and light within the canopy which helps maintain a healthy tree.
If you would like more clearance between the base of the tree and the crown then Greenbelt Tree Surgery Specialists can lift the crown. Crown lifting is a great way of creating more usable space in your garden, we remove the lower branches of the tree which if possible should be carried out before the tree reaches maturity to prevent any large wounds.
