Pruning is a horticultural, arboricultural, and silvicultural practice involving the selective removal of certain parts of a plant, such as branches, buds, or roots. The practice entails the targeted removal of diseased , damaged, dead, non-productive, structurally unsound, or otherwise unwanted plant material from crop and landscape plants .
Regulatory pruning: This is carried out on the tree as a whole, and is aimed at keeping the tree and its environment healthy, e.g., by keeping the centre open so that air can circulate; removing dead or diseased wood; preventing branches from becoming overcrowded (branches should be roughly 50 cm (20 in) apart and spurs not less than 25 cm (10 ...
Pollarding tends to make trees live longer by maintaining them in a partially juvenile state and by reducing the weight and windage of the top part of the tree. [6] Older pollards often become hollow, so it can be difficult to determine age accurately. Pollards tend to grow slowly, with denser growth-rings in the years immediately after cutting.
Branches of most trees are relatively horizontal, live oaks being a classic example. As the live oak grows larger, its branches do, too. And as the branches grow larger, so will the roots.
While the perceived risk of death by falling trees (a part of the "tree risk" complex) is influenced by media and often hyped (the objective risk has been reported to be close to 1 : 10.000.000, almost as low as death by lightning), [6] singular events have encouraged a "proactive" stance so that even lightly damaged trees are likely to be removed in urban and public traffic surroundings.

Branch attachment in common ash Fraxinus excelsior L. Figure 1: Anatomical drawing of the wood grain of a branch attachment in a tree. Initially branches are mechanically attached to the trunks of trees by forming interlocking wood grain patterns at the top of the joint, within what is known as 'axillary wood' (Fig. 1). [1]
Pruning shears, also called hand pruners (in American English), or secateurs (in British English), are a type of scissors used for plants. They are strong enough to prune hard branches of trees and shrubs , sometimes up to two centimetres thick.
Arboriculture (/ ˈ ɑːr b ər ɪ ˌ k ʌ l tʃ ər, ɑːr ˈ b ɔːr-/) [1] is the cultivation, management, and study of individual trees, shrubs, vines, and other perennial woody plants. The science of arboriculture studies how these plants grow and respond to cultural practices and to their environment.
