There is no law in the UK that prohibits anyone from cutting down trees or pruning hedges at any time of the year. However, it is recommended to do any work on the trees during the winter months, when you can see inside the tree and the tree itself is dormant. If the tree, or trees, add up to 5 cubic meters of wood by volume, it is usually an offense to cut them down without a logging license. When deciding to prune or remove a branch, it is important to consider when to perform the work.
Pruning should usually occur after the leaves have “blushed” and hardened, from late spring to summer. However, there are some exceptions, since some species such as birch, walnut and maples, will “bleed” the sap and risk losing valuable sugars in the process if pruned in early spring. Therefore, pruning of these trees should be carried out when this risk is low: during the nesting season of birds according to Natural England which begins on March 1 and runs until July 31. It should be noted that birds may nest before and after this period of time. This may be the case even if tree conservation orders are not enforced or if the property is not within a conservation area.
RHS tree experts no longer recommend pruning or painting wounds in most cases, as they seem to inhibit healing and can actually promote rot. These reasons could include improving the structure of the tree, removing dangerous or defective branches; reducing shade, reducing wind load, or to provide space between the tree and a structure. Depending on the nature of the tree, all trees have different seasons when it is the optimal time to prune them. For most other deciduous trees, pruning in winter is easier as the branches are more visible, but it is better to do this before Christmas, as subsequent pruning can cause bleeding. Deliberately cutting down, uprooting or destroying a tree protected by a tree conservation order without a permit is a crime.

Falling outdoor temperatures also help to play its role in stopping the growth of trees. They are created to protect trees that are considered to have significant service value within the local area. Certain fungi and bacteria can enter the tree through these wounds and cause decay of the tree's woody structure. Subsequently, they will need to be reduced, which will allow the selected shoots to regrow and return an attractive shape to the tree. Because each cut has the potential to change the growth of the tree, no branch should be removed without a reason.
