Some common reasons for tree surgery:
- Dead trees
- Risk of direct damage
- Indirect damage (subsidence)
- Space Competition
- Increasing fruit production
- Increasing light or opening views

Main types of tree surgery:

Crown lifting / crown raising: to increase walking space, light and wind under the tree, the removal of the lowest branches, side branches, or parts of branches. The process is usually defined by the height of the lowest branches after surgery, for example "raise crown to 3 m above ground level".

Crown thinning: The even removal throughout the crown of selected branches, side branches, or parts of branches back to growing points. Usually a fraction of the crown is removed, for example "thin crown by up to a third". Thinning lets more light and wind through the tree.

Crown reduction: The removal of the outermost parts of branches, or side branches, back to growing points, to reduce the tree's height and spread. Reduction is usually defined as a fraction of the crown to be removed, for example "reduce crown by up to a fifth", and/or by the maximum length of branch to be removed, and/or the size of the tree afterwards, for example "reduce crown, removing up to 4 m, to leave crown 15m high by 10 m wide". The process lets more light and wind above and around the tree.

Often a combination of crown lifting, thinning, and reduction may be used. Other work like dead wooding, removal of dead and/or dying branches, and cleaning out (removal of broken branches, crossing branches, stubs from previous bad pruning, and climbers like honeysuckle, ivy, wild clematis).

Coppice and pollards: Trees can be cut back regularly to the same points and stay healthy only if this is done from an early age by somebody with experience. Coppicing (cutting to ground level in woods) and pollarding (cutting to a 6'-15' stump in wood pasture) were traditionally used to produce poles for building and fuel. In gardens, coppicing can be useful to stabilise steep slopes. In streets or gardens a form of pollarding can be used which leaves a framework of branches. Like pollarding, it should be started when the tree is young.
