Tree Crown Reduction
Usually carried out to prevent the tree limbs from growing too large (which can result in them breaking off) or if the customer simply decides that the tree is too big or too close to a building. The whole crown of the tree will be worked on.
Crown reduction is the reduction in height and/or spread of the crown (the foliage bearing portions of a tree) and can be carried out on all varieties of tree. Crown reduction may be used to reduce mechanical stress on individual branches or the whole tree, making the tree more suited to its immediate environment, or to reduce the effects of shading and light loss, etc.
The final result should be to retain the main framework of the crown, which is a significant proportion of the leaf bearing structure and to leave a similar, although smaller outline and not necessarily achieve symmetry for its own sake. Pruning a tree into a perfect circle, nicknamed ‘Lollypopping’ is not the correct way to reduce a tree.
Crown reduction cuts should be as small as possible and in general not exceed 100mm diameter unless there is an overriding need to do so.
Reductions will be specified by actual measurements, where possible, and reflect the finished result, e.g. ‘crown reduce in height by 2.0m and lateral spread by 1.0m. Reduction should not be confused with ‘topping’, which is an indiscriminate and harmful treatment.
