Trimming and pruning are the same work: removing dead, damaged, or crowding limbs so the tree stays healthy and safe. We recommend removal only when a tree is dying, diseased, structurally failing, or a hazard to a home. An ISA Certified Arborist assesses every tree before we recommend either.
Homeowners say “trim.” Arborists say “prune.” It is the same job: taking out dead, damaged, diseased, or crowding limbs so the tree keeps its structure, gets light and air through the crown, and stops dropping things on your roof.
Prune it when the tree is healthy and the problem is a limb, not the tree: deadwood over the house, branches on the roof or the gutters, a crown that has gotten heavy and one-sided, a young tree that needs structure. For a valuable tree with a weak union or a split, cabling and bracing can add years.
Remove it when the tree itself is the problem: it is dying or dead, diseased in a way that will not recover, structurally failing (a rotten base, a big crack, a lean that is getting worse), or it is a hazard to a home, a power line, or the people under it. Dying trees come down before they come down on their own.
What we will not do: top a tree. Topping (cutting the main leaders back to stubs) makes a weak, ugly tree that costs more later. If a tree is too big for its spot, we will tell you whether a reduction can fix it or whether it should come out.
Every job at Trailhead starts with an ISA Certified Arborist looking at the tree in person. If it can be saved, we say so. If it needs to come out, we say that too.
