Tree Health Assessment in McKinney, TX

Understand What's Happening With Your Trees

A tree that looks fine from a distance can be silently declining. Fungal infections, boring insects, root rot, nutrient deficiencies, and internal decay often develop for months or years before visible symptoms appear — and by then, treatment options may be limited. NTX Tree Experts provides comprehensive tree health assessments that catch problems early, when intervention is most effective and least expensive. Our evaluations cover everything from canopy condition and bark integrity to root zone health and soil composition.

North Texas trees face a specific set of threats. Oak wilt is an aggressive fungal disease that has killed thousands of red oaks and live oaks across Collin County. Hypoxylon canker attacks stressed post oaks and other hardwoods, especially after drought. Emerald ash borer, while still moving through Texas, poses a growing threat to ash populations. Bacterial leaf scorch, cotton root rot, and various scale and borer infestations are also common in the McKinney area. Our arborists know these local threats inside and out and can identify the telltale signs that general landscapers often miss.

During a health assessment, we examine the entire tree systematically: the crown for dieback, discoloration, and thinning; the trunk for cankers, cracks, fungal fruiting bodies, and boring insect activity; the root flare for girdling roots, soil compaction, and signs of decay; and the surrounding soil for drainage problems and nutrient issues. When deeper investigation is needed, we use tools like resistograph drilling to map internal decay and soil probes to assess root zone conditions.

Every assessment ends with a clear, written report that includes our findings, a risk rating, and a recommended treatment plan. If the tree can be saved, we outline the steps — whether that is targeted pruning, fungicide injection, insecticide treatment, soil amendment, or a combination of approaches. If the tree is beyond recovery or poses an unacceptable safety risk, we will tell you that honestly and help you plan for removal and replacement.

What Our Assessment Covers

• Canopy evaluation — Crown density, dieback patterns, leaf discoloration, and abnormal growth.
• Trunk and bark inspection — Cankers, cracks, cavities, fungal conks, and insect boring activity.
• Root zone analysis — Girdling roots, soil compaction, drainage issues, and root decay indicators.
• Pest identification — Species-specific diagnosis of insect infestations and boring damage.
• Disease diagnosis — Identification of oak wilt, hypoxylon canker, bacterial leaf scorch, cotton root rot, and other local diseases.
• Written report and treatment plan — Clear findings, risk rating, and recommended next steps.

What the Texas A&M Forest Service Reports on Two Local Threats

Emerald ash borer is confirmed in Collin County. As of June 2026, the Texas A&M Forest Service lists 40 Texas counties with confirmed emerald ash borer, Collin County among them. Its larvae feed under the bark of ash trees. Once an ash is infested it is likely to die, and where the insect is well established it can kill an ash within one year of the first infestation. Signs include dark green adult beetles about one-half inch long, which fly between May and June, and D-shaped exit holes in the bark about one-eighth of an inch wide. Because the beetle can survive for up to two years after a tree is cut down, the agency advises chipping, burning or burying an infested tree where it is rather than moving it.

Oak wilt spreads through fresh wounds and connected roots. Sap beetles carry oak wilt spores to new trees and are very active in late winter and early spring. The Forest Service advises against pruning or wounding oaks from February through June, and says every oak wound, including those from pruning, construction, lawnmowers, string trimmers and storms, should be painted over. Underground, oak wilt spreads an average of 75 feet a year through connected roots, mostly in live oaks. Signs include yellow and brown veins in live oak leaves and, in red oaks, leaves turning red or brown during the summer.
