Trees should be pruned every two to five years, depending on its age and type. Young trees should be inspected and pruned every two to three years. Mature trees should be inspected and trimmed every three to five years, and fruit trees should be pruned annually with a careful eye on seasonal growth. Evergreens typically don’t need pruning, unless branches or limbs are damaged, diseased, or harboring pests.

Trimming a tree can take anywhere from just two hours to a full day, depending on the age of the tree, the number of trees, and the species. Young trees are generally easier to trim, as their branches are often thinner in diameter and easier to reach compared to mature trees. They also tend to be healthier. If you haven’t trimmed your trees before or it’s been a while, the process could take even longer.

Generally, you should prune around 20% of an apple tree’s growth—and never more than 30%. This means that if you have a severely overgrown tree, it can take a few seasons to prune it back enough to produce the healthiest fruit. 

If you’re dealing with a newly planted or juvenile tree, hold off on pruning beyond the initial shaping. Wait at least a couple of seasons into fruit production since pruning can increase the number of water sprouts and unproductive foliage.

We don’t recommend DIY tree trimming for a few different reasons. First, the tools required to trim a tree can be costly, up to $1,100 or more, for the ladders and specialized saws needed. 

Safety is another concern, especially when working with more mature trees. As a guideline, you should only DIY tree trimming when branches are less than two inches in diameter. Any more, and the safety risk becomes too high, which could lead to catastrophe. For this job, it’s safest to let a tree-trimming professional assess the work needed.
