Crown reduction is reducing the overall height and span of the tree. The size of the crown is reduced while preserving its natural shape
as much as possible. This can be done in conjunction with crown lifting to create a balanced shape.
The removal of dead, dying, diseased, weakly attached and low vigour branches from the crown. This
procedure is important for maintaining the health of the tree and preventing decay and disease. Cleaning
the crown is a relatively simple and inexpensive way to greatly improve the health and appearance of a tree.
Thinning out the Crown
Removing a selected proportion of secondary branches from within the crown. Thinning allows greater
light penetration into the crown, which helps to improve the health of the remaining branches. This
is done by visually assessing the structure of the crown and selecting the most appropriate limbs to
remove to maintain a sound branching structure.
Lifting the Crown
This is simply the removal of lower branches from the base of the tree, for convenience or aesthetics, for example,
increasing clearance for pedestrians and traffic. Experienced tree surgeons understand which pruning methods are most
appropriate and how different trees respond to these methods.
