Tree and shrub services in Cumberland, Maine.

All of Cumberland County lies inside the state's emerald ash borer quarantine. Ash logs, branches and stumps and hardwood firewood cannot leave the quarantine area without Maine Forest Service approval, so ash pruning debris stays local.

Pruning inside the shoreland zone also has limits. Maine DEP's vegetation guidelines keep a buffer 100 feet from great ponds and rivers and 75 feet from other waters, cap tree removal at 40 percent of volume in ten years, and allow no canopy openings over 250 square feet. Cumberland's own Chapter 226 extends the shoreland zone 250 feet from the coast, lakes and wetlands, so structural pruning for a view on a Foreside lot is planned to stay inside those rules.

Shrub trimming is timed by plant: spring-flowering shrubs right after bloom, most others in late winter when the structure is easy to see.

Invasive vines are the other recurring problem. The town plan lists Asiatic bittersweet and black swallowwort among Cumberland's common invasives, and bittersweet in particular climbs into and strangles trees along field and forest edges, so cutting it back is often part of a pruning visit.

Plant health care also means reading a tree against its site. A tree in the zone 6a Foreside faces salt air and wind off the bay, while one in zone 5b West Cumberland deals with a colder winter, and pruning and treatment are adjusted to that.
