In regards to tree maintenance, there are two types of tree trimming: the type that you commit on a tree because you are concerned that its branches are turning into a hazard, and the sort you commit on a tree as you realize that some selective pruning can improve the tree's health and longevity.

When to Trim
Arborists are united in stating that trees with damaged, diseased, pest-ridden, or dead limbs must possess those limbs removed whenever possible. They also note that in the event you've got the option, there's decidedly the best time to prune: right at the transition from winter to spring.
It is also worst to prune a tree during very hot periods, very cold periods, or very dry periods. The heat causes sap to flow faster, and a pruning harm may result in excessive sap loss.
The Way to Trim
When trimming a tree for health reasons, you'll want to decrease the branches as close to the bottom as possible, without leaving behind a stub, but without eliminating extra bark from the rest of the body of the tree.
'Topping', or haphazardly cutting the bigger branches or the whole surface of a tree, is not wise. If you will need to remove one fork of a split tree, work from the outside in, pruning that forks' branches until the fork of the trunk remains, then cut off the fork a half-inch or more away from the primary trunk's body.
