A tree may need pruning for a variety of reasons:
· to remove diseased or storm-damaged branches
· to thin the crown to permit new growth and better air circulation
· to reduce the height of a tree
· to remove obstructing lower branches
· to shape a tree for design purposes
In horticulture, the removal or reduction of parts of a plant, tree, or vine that are not requisite to growth or production, are no longer visually pleasing, or are injurious to the health or development of the plant. Pruning is common practice in orchard and vineyard management for the improvement of flowering and fruiting.
In the case of a large tree where you want to remove big branches in the upper area of the crown, it may be best to hire experts. Large tree pruning, in particular, can require climbing and or even ariel devices and chain saws. This is a job that should be left to trained and experienced professionals. Never compromise personal safety in pruning a tree.
