This is normally achieved by removing the lowest branches of the tree crown, to a specified height. It’s an operation often undertaken to provide better access under a tree, for mowing or walking, but tree crown lifting is actually a very cheap and effective way of increasing the amount of light under a tree.
Tree crown lift with care
When lifting (or raising) the crown of mature trees, care should be taken to avoid the removal of major limbs which can leave large wounds. These can provide access for decay, fungi and disease and also impair biomechanical properties. A tree crown lift should involve the removal of secondary branches or branch shortening rather than removal of branches back to the stem, provided that the desired clearance can be achieved.to top
