Large pruning wounds, such as those left behind in trees after topping, may become entry points for pathogens and may result in extensive decay. Decay undermines, to greater or lesser extent, the long-term health and physical stability of trees; most notably in those species which compartmentalize decay less effectively. Should a tree survive ...
Topping: Topping is a very severe form of pruning which involves removing all branches and growths down to a few large branches or to the trunk of the tree. When performed correctly it is used on very young trees, and can be used to begin training younger trees for pollarding or for trellising to form an espalier .
[23] [29]: 70 [30] Pruning above a leaf node can steer plant growth in the direction of the natural placement of that leaf bud. [5] [4] Pruning may also be used to keep a design free of unwanted branches and to reduce canopy size. [23] [30] Pruning is sometimes the only technique used to craft a project. Deciduous trees are mainly pruned in ...
Some trees may be rejuvenated by pollarding – for example, Bradford pear (Pyrus calleryana 'Bradford'), a flowering species that becomes brittle and top-heavy when older. [ citation needed ] Oaks, when very old, can form new trunks from the growth of pollard branches; that is, surviving branches which have split away from the main branch ...
An apple tree sprout is being converted to a branched, fruit-bearing spur by an arborist. Numbers show the sequence of cuts, which occurred during two years. Plants form new tissue in an area called the meristem, located near the tips of roots and shoots, where active cell division takes place.
When pruning older trees, prune out dead, weak, diseased and insect-infested branches and also remove low, broken and crossing branches. [19] The quality of pruning has significant effect on the infection by fungal pathogens, which can consequently cause stem disease.

Tree shaping (also known by several other alternative names) uses living trees and other woody plants as the medium to create structures and art. There are a few different methods [2] used by the various artists to shape their trees, which share a common heritage with other artistic horticultural and agricultural practices, such as pleaching, bonsai, espalier, and topiary, and employing some ...
Professional pruning shears often have replaceable blades. There are three different blade designs for pruning shears: anvil, bypass and parrot-beak. Anvil pruners have only one blade, which closes onto a flat surface; unlike bypass blades it can be sharpened from both sides and remains reliable when slightly blunt. Anvil pruners are useful for ...
