When to Call an Arborist, and When You Can Handle It Yourself

Call an arborist when the work needs a ladder, a chainsaw off the ground or anything near power lines. The same applies to large limbs over your house or a storm-damaged tree. You also need one when you don't know what's wrong with a tree. Light pruning from the ground, watering and mulching are fine to do yourself.

Some tree care suits a handy homeowner with the right tools. Other jobs carry consequences serious enough that you should call someone. This guide explains where that line sits, both for your safety and for the tree's health.

What tree work can you do yourself?

You can safely do light work from the ground on small trees. Here's what usually falls on the DIY side.

Light pruning from the ground. Clipping small branches on young trees, removing water sprouts and cutting suckers at the base all carry little risk. Hand pruners, loppers and a handsaw handle most of it. A pole pruner also works for branches a bit higher, as long as you stand on firm ground.

Small tree and shrub care. Most homeowners can safely trim hedges, shape small shrubs and prune young trees they can reach from the ground.

Stump treatment. After a professional removal, you can apply a stump treatment to discourage regrowth.

Cutting up a small fallen tree. If a small tree is fully on the ground in an open spot, cutting it up is reasonable work. That's only true when the trunk isn't bent or pinched by the way it fell. See the section on storm wood below.

Watering and mulching. Watering during droughts and keeping a mulch ring around young trees do a lot of good. Better still, they carry almost no risk.

Where does the risk increase?

The risk jumps once you leave the ground, pick up a chainsaw near the tree or work near lines.

Anything that needs a ladder. This is the biggest dividing line. Ladders are unstable in trees, and branches move in ways you don't expect when cut. Add a chainsaw, and a kickback from a shaky perch can be catastrophic. So if the job needs a ladder and a power tool, think hard before you do it.

Chainsaw work off the ground. On the ground, with training and protective gear, chainsaw risk is manageable. Up on a ladder or a slope, however, a slip becomes far more serious. Professional climbers use saws aloft because they have the rigging, training and positioning gear. Without those, the risk is different.

The International Society of Arboriculture says it plainly in its Pruning Mature Trees guide: "Pruning large trees can be dangerous." It adds that work above the ground or with power equipment belongs with a trained professional.

Storm-damaged trees and wood under tension. This deserves special care. A log that seems to lie flat may be bent under its own weight or pinned by another tree. Cut in the wrong place, and the wood can snap shut on the saw or spring up suddenly. Experienced crews read those forces before every cut.

Work near overhead lines. Any tree touching a line, or close to one, is not DIY territory. That includes the service line from the pole to your house. OSHA's 29 CFR 1910.333 keeps untrained workers 10 feet from live overhead lines of 50 kV or less. Closer work needs the utility to cut power or a crew trained for it. See tree removal near power lines.

Felling a tree of any real size. Felling means planning the direction of fall, reading the lean and keeping an escape route clear. If the tree goes the wrong way, it can hit a house, a car, a line or a person. In an open field, a trained, experienced person can handle small removals. Near structures or lines, though, it's professional work.

Customers notice when a crew takes safety seriously. As Rob R. put it, "We also could see that safety was a concern for everyone."

When do you specifically need an arborist?

You need an arborist when the question is about judgment, not just labor. Here are the common cases.

When you don't know what's wrong. A declining tree with odd symptoms needs a diagnosis, not a guess. Acting first can make things worse. For example, heavy pruning on a diseased tree can speed its decline.

When you need documentation. Insurance claims, HOA disputes, boundary-tree conflicts and property sales may call for written professional findings. That's an arborist's job.

When the structure is complex. Think of trees with weak forks, old topping cuts or other defects. Pruning them means knowing how each cut changes the rest of the tree. You can't judge that from the ground.

When the stakes are high. A big oak over your roof is no place to experiment. Professional pruning costs a fraction of a roof repair.

Does hiring a professional make economic sense?

Usually, yes, once you count the real alternatives. Professional tree work costs what it does because of the equipment, insurance, training and physical risk. But you're not comparing a pro's fee with doing it for free.

Instead, you're comparing it with the cost of an injury, a damaged roof or a tree made worse. For risky work, the professional option usually wins, even before you count safety.
