Tree Health & Risk Assessments in Alpharetta, GA

Tree health and risk assessments answer one question for each tree: is it likely to fail, and if so, what can be done about it? For Alpharetta homeowners, that question usually starts with something they noticed: a pine turning yellow at the top, bark sloughing off an oak, mushrooms at the base of a trunk, a new lean after a storm, or a big tree beside a recent addition or pool. Sometimes the answer is that the tree is fine. Sometimes it needs pruning, treatment or removal. Either way, a clear answer lets you decide with real information.

What we look at

A visual assessment starts at the ground and works up. At the base: root flare buried or exposed, girdling roots, fungal fruiting bodies, cracks, cavities and soil heaving. On the trunk: seams, cankers, loose bark, old wounds and lean. In the crown: dead branches, thinning or off-color foliage, weak V-shaped forks with included bark, and limbs that hang over targets like the house or a play area. We also look at what has changed around the tree, since that is often the cause.

Pines and bark beetles

The Georgia Forestry Commission links Ips engraver beetle outbreaks to drought, and lists the signs: a discolored crown, dying branches, pitch tubes, red sawdust on the bark and frass in spider webs at the base, with I-, H- or Y-shaped galleries under loose bark. Preventive systemic insecticides may help protect a high-value pine before it is attacked, but once symptoms appear the tree cannot be saved. Our job is to tell you which pines are already lost, which nearby ones are at risk, and which are healthy.

Oaks, hypoxylon and construction

The USDA Forest Service describes hypoxylon canker as a fungus that lives in the bark of healthy oaks and other hardwoods and does little harm until the tree is weakened by drought, root disease, mechanical injury or construction. Then it can kill the tree. That pattern is common in North Fulton, where houses, pools and additions are built inside the root zones of large oaks. UGA Extension notes that active roots grow mostly in the top 18 inches of soil and that the root zone can span 1 to 1.5 times the tree's height, so damage from trenching or heavy equipment often shows up in the crown a few years later.

Emerald ash borer

Emerald ash borer was first detected in Georgia in 2013 in Fulton and DeKalb counties and had been found in 53 Georgia counties by 2023. Ash is not a dominant yard tree here, but where green or white ash grows near a house, it is worth checking for thinning crowns, woodpecker damage and D-shaped exit holes.

Specimen trees and permits

Alpharetta protects larger specimen trees, and city rules call for a closer look before they can come out. An assessment helps in two directions: it can show that a declining specimen tree has a real reason to be removed, or it can show that a healthy one is worth keeping with some pruning or support. Assessments are visual and practical, and if a tree needs advanced testing such as resistance drilling or a formal written risk report, we will tell you.
