• Tree health assessment: $150

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.

It depends on the problem, the affected part of the tree, the risk of the pathogen spreading, and the overall health of your tree. Many diseases, fungal infections, and insect infestations can be successfully treated, especially if the issue is only in a few branches. However, if a disease is too widespread, too severe, too easily spread, or in the roots, the tree will likely need to be removed.

While trees can grow in the curb strip between the sidewalk and the street, this placement often poses the problem of interfering with overhead power lines. It’s best to consult your local utility provider and tree planting service before transplanting a tree that might grow into power lines. Also, you should never work within 20 feet of a live power line to avoid the risk of electric shock. Tree branches should never touch nearby power lines, so it’s essential to ensure your tree isn’t in danger of growing too close to them.
