The most important decision to make on when to prune trees is whether the action will actually benefit the tree in some way. Only prune the tree if it will benefit its growth and life span.
Pruning trees then is not always a necessity but is often helpful in maximizing their growth and/or producing greater flowering and fruit production. Sometimes, of course, pruning is essential. Particularly if strong winds have broken branches-off leaving unsightly breaks. Or, if branches are dangerously hanging off near properties or public areas which could lead to potential injury.
Trees over ten years old will compete with others for sunlight, nutrients, water and space. Removing larger branches will allow other trees to receive their share of valuable sunlight and air. A tree planted too close to another isn't practical. If there are trees too close together it may be an idea to remove some completely for better growth. Pruning can also help reduce disease and decay.
Fruit trees in particular, survive much better after pruning. Apple trees, for example, can produce many branches each baring leaves that block sunlight. Pruning the tree will help apples to grow larger. If branches need to be removed higher up the tree, then call experts out who have proper safety harnesses and equipment to do the job safely and professionally.
There are different ways of pruning a tree; 'crown raising' is implemented to create space near the lower level of the tree for pedestrians to walk round/ past; 'crown thinning' is implemented to allow more sunlight to the tree; 'crown reduction' may be undertaken to lower a tree which has grown too high for its position. Like any type of gardening, however, it is incredibly important to do your research first.
Different methods are often required when pruning different trees. Sometimes different tools are needed. Larger branches will require a chainsaw, while smaller, thinner branches can be pruned with shears or a saw. It will also depend on the amount of branches that need pruning. Assess the tree first and figure out which is the most effective method to use.
A license is often required to use a chainsaw and strict safety precautions must be adhered to. If branches need to be supported as you cut them, don't do it yourself. The chainsaw must be supported with both hands to eliminate accidents. When using the chainsaw, don't cut too close to the trunk as you may strip it of bark. Instead, cut a short way out to avoid the problem.
