Tree Service questions, answered by experts

Pruning is an effective way to prevent a diseased branch from infecting the rest of the tree. If the infection isn’t caught early enough and the pathogen has spread to the trunk or the majority of the branches though, it is too late to prune off the affected areas and you’ll likely need to remove the tree.

In most cases, leaving tree roots underground is not a problem if the stump has been removed or ground below the soil. However, some larger roots may decompose, leaving dents in your soil. Additionally, some aggressive trees, including willows, oaks, elms, maples, and poplars may grow back from roots. Large aggressive trees with established root systems are more likely to grow back.

Only trim palm trees as needed, which is usually about once per year. However, don't stick to that schedule if the palm tree doesn't need it. Avoid trimming palm trees when possible. It’s best to trim palm trees only when you notice a buildup of dead fronds. That said, leave the brown fronds during the dormant season because this organic matter helps protect the tree from the cooler weather.

Often, it’s the homeowner’s responsibility to handle the aftermath when a neighbor’s tree falls on their property. But if a tree has been obviously dead for a significant period of time and caused damage when it fell, a case can be made that the owner should have removed it, especially if the neighbor wrote you a letter about the tree or asked you to take it down. This can be grounds for a successful lawsuit in claims court and is a good reason to always pay attention to your trees and remove dead trees before they fall.

The best time to transplant a tree is when it is dormant. For many trees, this means either in the fall after the leaves have dropped (around October or November) or in early spring before new growth begins (around March). The ideal timing can depend on the type of tree. Deciduous trees do well when moved in early spring or fall, while evergreens are best transplanted in early spring or late summer. For example, pine trees are best moved in early fall, but maples prefer late fall. Avoid transplanting in winter, as the frozen or hard, cold soil poses a significant risk to the roots and prevents the tree from acclimating properly.
