When it comes to landscaping, trimming trees and shrubs is essential for keeping them healthy and beautiful. The natural shape of a plant is usually the best option, with the upper part being narrower than the bottom to ensure that sunlight can reach all the leaves. Pruning at planting time does not have a positive effect on transplant survival and growth. Pruning is different from trimming, as it involves reducing the size of the tree without taking into account its long-term health or structural integrity. A natural pruning system accentuates a tree's natural branching habit and corrects structural defects and future problems by developing a stronger and healthier tree.
Street trees or trees along walkways should have branches tall enough to accommodate pedestrians and vehicle traffic, signs and traffic lights. The need for pruning can be reduced or eliminated by selecting the right plant for the location. Young trees can be trained using pruning techniques that will help promote plant health and longevity. The general pruning procedure applies to many large shrubs and small tree species. Tree injuries that expose wood or kill bark can allow insects or pathogenic organisms to enter the tree. Plants used in formal hedges and foundation plantations, such as yew and privet, can be trimmed with hedge shears to shape and stimulate new growth.
Evergreen nursery stock for hedges does not need to be as small as deciduous material and should not be cut when planted. While large trees that are grown for shade, protection, or wind protection may need pruning every few years, smaller ornamental trees and shrubs often require more frequent care. Pruning consists of removing or reducing certain parts of the plant that are not needed, that are no longer effective or that do not serve the plant.
