Diagnosis before treatment
No reputable arborist treats a tree without diagnosing it. On a Palmer visit we identify the species, examine the symptom pattern (which leaves, what color, what season, which part of the canopy), check the root flare and soil, and look for the tell-tale signs of each major disease. When the picture is ambiguous, we submit samples to the Texas Plant Disease Diagnostic Laboratory for lab confirmation before spending your money on treatment.
Oak wilt — the Palmer emergency
Oak wilt is the most serious tree disease in Ellis County: it can kill a red oak in a single season and spread tree-to-tree through grafted live-oak roots. Treatment is propiconazole macro-infusion at the correct dose per inch of trunk diameter, often paired with trenching to sever root grafts in a confirmed outbreak. Timing and dosage matter — this is not a do-it-yourself fungicide.
Bacterial leaf scorch & iron chlorosis
Bacterial leaf scorch slowly kills mature Palmer oaks — marginal leaf browning with a yellow halo, worst in late summer — and is managed with annual oxytetracycline injections. Iron chlorosis (yellow leaves, green veins) is a nutrient lock-up from our alkaline clay, corrected with chelated iron-and-manganese trunk injection that bypasses the soil entirely. Both are commonly mistaken for drought; correct identification matters.
Anthracnose, cankers & blights
Wet DFW springs bring anthracnose (leaf and twig blight on oaks, sycamores, and elms) and various canker and tip-blight fungi. Most are managed with a combination of correctly-timed protective applications, sanitation pruning of infected wood, and reducing the tree's underlying stress — not a single miracle spray.
Root & soil-borne disease
Phytophthora and other root rots attack trees in poorly-drained Palmer clay, showing up as canopy thinning and dieback that is easy to misread as a canopy problem. Diagnosis here is about the roots and drainage — treatment combines soil and grade correction, root-collar excavation, and targeted fungicide where warranted.
