How To Identify Diseased Trees On Your Irwin Property?

Healthy trees add beauty, shade, and value to your property, but when a tree becomes diseased, it can quickly turn into a safety hazard. In Irwin and the greater Pittsburgh area, weather changes, pests, and environmental stress can make local trees more vulnerable to illness. Knowing how to identify the early signs of disease can help you take action before it spreads to nearby trees or leads to costly removal.

Here’s how to spot the warning signs of diseased trees on your property and what to do about them.

Discolored or Wilting Leaves

One of the first signs of tree disease is a change in leaf color or texture outside the normal seasonal cycle. Watch for:

• Yellowing leaves in mid-summer (a possible sign of root rot or nutrient deficiency)

• Brown, crispy leaves that appear even when the tree is watered

• Wilting or curling leaves that fall prematurely

  
  

Diseases like anthracnose, oak wilt, and bacterial leaf scorch are common in Pennsylvania and often show these symptoms. If only one section of the tree shows discoloration, it may indicate infection localized to a specific branch or root zone.

Fungal Growth or Mushrooms Near the Base

Fungi are a major indicator of decay. Mushrooms or conks growing around the base of the tree or along the trunk suggest internal rot. The fungus feeds on decaying wood, which means the tree’s structural integrity is already compromised.

If you see shelf-like fungi attached to the trunk or roots, it’s important to have the tree inspected quickly. Left untreated, decay can spread and make the tree more likely to fall during storms.

Cracked, Peeling, or Sunken Bark

Healthy bark should be firm, intact, and consistent in texture. When you notice cracks, peeling sections, or deep grooves, it can mean the inner layers are dying. Bark beetles and other pests often invade through these weak spots, worsening the damage.

Sunken or cankered areas on the trunk are another warning sign of disease. These areas often ooze sap or dark fluid and may smell sour or musty, both signs of bacterial infection.

Dead or Dying Branches

Dead branches are more than just unsightly; they often point to deeper problems. If you see brittle, leafless limbs near the top or outer edges of your tree, it could mean the tree is struggling to transport water and nutrients.

Diseases such as Dutch elm disease and fire blight can cause progressive dieback from the tips downward. If multiple large branches are affected, the entire tree may already be compromised.

Holes or Sawdust at the Base

Tiny holes in the trunk, piles of sawdust, or wood shavings near the base often signal insect infestation, which can accompany or accelerate disease. Insects like emerald ash borers, carpenter ants, and bark beetles commonly attack weakened or stressed trees.

If you notice increased bird activity pecking at the trunk, that’s another hint that insects are present inside the wood.

Thinning Canopy or Uneven Growth

A sparse or uneven canopy where branches appear bare or stunted may indicate the tree is declining. While this can result from poor soil or drought, it’s also a symptom of systemic disease that affects water movement within the tree.

Compare the tree’s canopy to those of the same type on your property. If it looks patchy or lopsided, a closer inspection is needed.

When to Call a Professional

If you notice several of these warning signs, it’s time to call a certified tree service for a professional inspection. Arborists can diagnose the issue and determine whether the tree can be treated or needs removal. Acting early not only saves individual trees but also protects the rest of your landscape.
