Use hand pruners for branches no larger than the size of your little finger. Use loppers for branches no larger than the size of your thumb. Beware of overhead utility lines, windows, and other obstructions when using a pole pruner or when you are on a ladder. If you can't locate the branch bark ridge or collar of the limb, error on the side of caution and cut further out on the branch rather than close in. Remove no more than one-third of the tree crown in any one season.
Most people grow trees for their unique features, natural form and structure.
Topiary, pleaching, pollarding and espalier are all special forms of pruning. If you prune in these ways, your tree will not grow to its natural shape. You can avoid excessive pruning if, before planting, you decide on the function of the plant. Determine the available growing space and assess other limiting factors, such as water, soil, exposure, potential for disease and insect problems, pests and maintenance. Visit older neighborhoods.
