Specific Questions About Trees and Shrubs
If you have questions or concerns about your larger trees (or all your woody plants), you may want to contact a Massachusetts certified arborist. A certified arborist can diagnose problems and prescribe treatments (pruning, applications, removal, etc.) to improve the health of plantings. There is a local resource with a list of certified arborists.
