2. Oak Trees – Signs of Oak Decline

Many mature oaks in Charlottesville are experiencing oak decline, a term used to describe a combination of stress factors, including:

• Crown thinning and branch dieback
• Brown leaf patches
• Little to no new growth
• Root Rot, which weakens the tree’s stability and health

Prompt diagnosis and professional treatment are key to saving valuable oak trees.

3. Crape Myrtle – Bark Scale & Powdery Mildew

Crape Myrtles are susceptible to Bark Scale, an invasive insect that feeds on tree sap. Symptoms include:

• White or gray scale insects on bark and branches
• Sooty mold on bark and foliage
• Yellowing leaves and stunted growth

Powdery mildew may also appear as white, powdery patches on leaves, particularly in shady or humid conditions.

4. Maple Trees – Scale Insect Infestations

Maple trees can suffer from scale insects, which suck essential nutrients from the tree. This causes:

• Gradual canopy thinning
• Loss of vigor and poor coloration
• Premature leaf drop and decline in overall tree health

Timely treatment can help restore the health of your maple.

5. Hemlock Trees – Woolly Adelgid Infestation

Hemlock Woolly Adelgids are invasive, sap-sucking insects that appear as white, cottony clusters on the underside of needles. Symptoms include:

• Needle discoloration and drop
• Fading or browning of branches
• Complete tree dieback if left untreated

Hemlocks should be inspected regularly for signs of adelgid activity.

6. Dogwoods – Anthracnose Fungal Disease

Dogwood Anthracnose is a fungal disease common in Charlottesville that causes:

• Brown or purple spots on leaves
• Lesions on twigs and young branches
• Progressive twig dieback, especially in shaded or moist environments

Early intervention with pruning and treatment can preserve your tree’s health.
