Yes, it can be good to remove dead branches from trees. Dead branches can lead to rot in other areas of the tree. They can also cause damage if they fall on a house, shed, fence, car, pool, or other structure or property. However, it’s important that dead branch removal is done safely. If the branch is high in a tree or requires a lift or ladder to access, consider calling a professional tree removal company, as they will have the experience and equipment to do the job safely.

Deciduous shade trees (the type of trees whose leaves fall off in autumn) need to be pruned in late winter—between February and March. That’s because it’s easier to find and remove sick or dead branches when no leaves are present. And wounds close and heal faster in colder temperatures so pruning them at this time also makes them less prone to infection.

Tree roots are hearty and complex systems, so they don’t die immediately after the rest of the tree is removed. If you leave the root system in place, it takes anywhere from two to seven years for it to run out of nutrients. It is worth noting, however, that the roots stop growing and expanding after cutting down the rest of the tree.

The best time to trim trees is in late fall through winter when the tree has slowed its growing for the year. Cold weather stops insects and fungal growth from attacking a new tree wound. Summer and fall are considered the worst times to trim trees, but it’s permissible in certain scenarios, such as tree disease, damaged branches, or small, aesthetic cuts.
