You should hire a professional team for their treatment so that your trees stay safe, healthy, and in good shape. 

6 Common Diseases of Pennsylvania Trees

Pennsylvania offers a healthy environment for trees. If you do not take timely steps, tree health can get worse. Let’s discuss in detail how to identify and treat them:

Apple Scab Tree Disease

Apple Scab is a common tree disease in Pennsylvania. It is caused by a fungal infection that thrives in wet and humid conditions. It affects apple trees and other related species. 

Signs of apple scab disease include yellowing leaves, as well as black and velvety spots that may appear on leaves. You may also notice premature leaf drop. In severe cases, the fruit may become deformed. Here is what to do after identifying the disease:

  • Remove fallen leaves and debris.
  • Apply fungicide in early spring.
  • Prune infected branches.
  • Choose resistant tree varieties.
  • Water trees at the base.

Cedar Apple Rust

Cedar Apple Rust is a fungal disease. It affects both cedar and apple trees. The disease requires both trees to complete its life cycle. The fungus spreads through wind-blown spores.

Common signs of this disease include bright orange-yellow spots on leaves. You may also see gelatinous galls on cedars. These galls swell during rainy weather. Apple trees may show distorted, deformed fruit. Treatment for this disease includes:

  • Remove infected branches and galls.
  • Apply fungicide during early spring.
  • Avoid planting cedars near apple trees.
  • Rake and dispose of fallen leaves.
  • Prune trees to increase airflow.

Anthracnose Disease

It’s a fungal disease that affects many tree species in Pennsylvania. The disease spreads during wet, cool weather, which is most active in spring and fall. Affected trees will show signs like dark, sunken spots on leaves. You may also notice dead areas on twigs. Trees like ash, oak, and sycamore are commonly affected, and their leaves may curl on drop early. Here are some tips to treat your trees:

  • Prune infected branches and twigs
  • Apply fungicide during wet seasons
  • Rake and remove fallen leaves
  • Water trees at ground level, and
  • Ensure proper tree spacing for airflow

Verticillium Wilt

Another fungus-infected disease which is caused by soil-borne fungi. It blocks water movement with the tree, which leads to wilting. The disease affects many types of trees, such as maples, elms, willows, and boxwoods. 

You should be aware of signs like yellowing or wilting leaves, while infected branches may die back. Taking the following tips may help with treatment:

  • Remove and destroy infected branches.
  • Avoid planting in infected soil.
  • Water trees deeply at the roots.
  • Use resistant tree varieties.
  • Improve soil drainage around trees.

Powdery Mildew

If you notice signs like white, powdery spots on leaves or curly leaves in your lilac, dogwood, and roses, then they can be signs of powdery mildew. You should contact a professional team immediately. Otherwise, trees can be stunted if you don’t take quick action. Professionals will:

  • Remove infected leaves and branches
  • Apply fungicide during early spring
  • Ensure good air circulation around trees
  • Water trees at the base only, and 
  • Prune to reduce tree density

Signs of a diseased tree include wilting or yellowing leaves, unusual leaf spots, cankers (sunken or dead areas on the bark), fungal growth, and excessive dead branches. If you notice these symptoms, a professional tree inspection is recommended.
