When trees become sick, the problem isn’t always obvious. Many diseases start small — with leaf spots, fungus, or subtle wilting — but if left untreated, they can spread quickly and cause irreversible damage. At West Coast Tree Service by TimberTEKS, our certified arborists provide expert tree disease evaluation services in Vancouver WA, Portland OR, and surrounding areas to diagnose problems early and recommend effective treatment.
🕑 Why Tree Disease Evaluation Matters
- Early Detection Saves Trees – The sooner a disease is identified, the more treatment options are available.
- Prevent Spreading – Many tree diseases are contagious and can harm nearby trees.
- Protect Property Value – Healthy trees enhance curb appeal, while sick trees can become safety hazards.
- Ensure Safety – Diseased trees are often weaker, more likely to drop limbs, or fall during storms.
⚠️ Signs of Tree Disease
If you notice any of these warning signs, your tree may be diseased:
- Leaves turning yellow, brown, or spotted out of season
- Fungus, mushrooms, or cankers on bark or roots
- Sudden dieback of branches or canopy thinning
- Oozing sap, cracks, or peeling bark
- Insect activity (boring holes, sawdust at the base, visible pests)
- Growth of mildew or mold on leaves
These symptoms often point to fungal infections, bacterial disease, or pest infestations.
🌲 Common Tree Diseases in the Pacific Northwest
- Anthracnose – Causes leaf spotting and early leaf drop.
- Root Rot (Armillaria & Phytophthora) – Fungal infections that attack the root system.
- Powdery Mildew – A white, powdery coating that weakens leaves.
- Verticillium Wilt – Soil-borne fungus that causes sudden dieback.
- Rust Diseases – Orange or reddish spots on leaves and stems.
- Cytospora Canker – Bark disease that creates sunken lesions and sap oozing.
Our arborists can diagnose these and other conditions with a thorough inspection.
