There's a right way and a wrong way to cut a tree β and the difference shows up for decades. Here's how ISA Certified Arborists prune trees correctly, following ANSI A300 industry standards.
Every cut you make on a tree is permanent. A good cut heals cleanly and makes the tree stronger; a bad cut invites decay, weakens structure, and can shorten the tree's life by decades. That's why professional pruning isn't about owning a chainsaw β it's about knowing exactly which branch to cut, where on the branch to cut it, how much to remove, and when. Escamilla Tree Service's ISA Certified Arborists prune to ANSI A300 β the American National Standard for tree care β on every job across metro Atlanta.
This page is a homeowner's guide to how proper pruning is actually done. Understanding the techniques helps you recognize quality work β and avoid the "tree guys" whose cheap cuts cost you a tree.
The most important part of any pruning cut is location. A tree heals by growing new tissue over the wound, and it can only do that if the cut is made in the right place:
ANSI A300 defines several distinct pruning types. The right one depends on the tree and the goal:
The golden rule: never remove more than ~25% of a tree's live canopy in one growing season β and far less for mature trees. Over-pruning starves a tree of the energy it makes through its leaves. Any "expert" who wants to strip your tree bare is about to damage it.
An ISA Certified Arborist identifies the tree's species, condition, and goals, then chooses the right pruning type and defines exactly what comes off β and what stays.
Every cut follows ANSI A300 β correct location at the branch collar, prune to laterals, three-cut method on heavy limbs, and conservative live-wood removal.
We rig and climb in ways that protect the tree and your property, then chip and haul all debris and leave the site spotless.

When a company says it prunes "to ANSI A300," it means cuts are made at the proper location, the right techniques are used, and live-wood removal stays within safe limits. Our ISA Certified Arborists follow it on every job.
Topping does make a tree smaller temporarily, but at a severe cost. The stubs decay, the tree responds with a flush of weak, fast-growing shoots that are poorly attached, and the exposed bark can sunscald. Within a few years the tree is taller, denser, weaker, and more dangerous than before β and it never recovers its natural form. Proper crown reduction achieves height control without the harm.
As a general rule, no more than about 25% of the live canopy in a single growing season for a healthy young or mid-life tree β and considerably less for mature or stressed trees. Leaves are how a tree makes its food, so removing too many at once starves and stresses it.
Just outside the branch collar β the slightly swollen ring where the branch joins the trunk or parent limb. Cutting there preserves the tree's natural defense zone so it can seal the wound. Cutting flush into the trunk, or leaving a long stub, both lead to decay.
No. Research has shown wound dressings and pruning paints don't speed healing and can actually trap moisture and promote decay. A properly placed cut on a healthy tree seals itself. The exception some arborists make is dormant oaks in oak-wilt areas, where a light sealant on fresh cuts can deter beetles.
You can safely handle small, low, light pruning β deadheading shrubs, trimming a low branch you can reach from the ground. But anything requiring a ladder or chainsaw, anything near power lines, and any structural or large-limb work is genuinely dangerous and easy to do wrong. Improper cuts can permanently damage a valuable tree, and falls and chainsaw injuries are common. For anything beyond arm's reach, hire an insured professional.
Ask whether they're ISA Certified and prune to ANSI A300, whether they're licensed and insured, and how much of the canopy they plan to remove. Walk away from anyone who offers to "top" your tree, uses climbing spikes for a non-removal, or wants to strip out most of the canopy. Good arborists remove less than you'd expect, and explain every cut.
