What Is Black Fungus?

Black fungus is a common sign of black knot disease, a severe fungal infection that can wreak havoc on a tree’s health, appearance, and structure. It often starts as a white or velvety green fungus and gradually turns black over time. The disease can make tree branches appear swollen and hard while generating large black knots along the limbs.

Although many tree species can contract black knot disease, cherry and plum trees are the most susceptible.

Common signs of black knot disease include:

  • Wilting and browning leaves
  • Infected limbs tilt to a specific side
  • Black knots form along branches
  • Rot and decay

Removing Fungus From Tree Bark: Best Practices

Homeowners can treat black knot disease if they act quickly. The longer you take to treat infected trees, the harder it is to eliminate the disease. Use the following fungal tree disease control tips to learn how to get rid of black fungus on trees.

Prune Infected Branches

Pruning is more than an effective tree health preservation practice. It’s also one of the best treatments for back knot disease and can help the tree regrow healthy branches. 

Use sharp shears to cut 2 to 4 inches below the knot to remove infected limbs. 

Once cut, burn or properly dispose of the branches to prevent them from infecting other trees. Also, sanitize your shears before cutting additional limbs to prevent the spread of the disease.

Apply Fungicide

Many home improvement stores sell fungicides that eradicate fungus and black mold on trees without jeopardizing their health. However, before applying the fungicide, trim infected branches and properly discard them. 

After cutting infected branches, follow the tree fungus treatment’s directions and spray it along the tree’s structure. It’s best to apply fungicide during spring when the temperature surpasses 60 degrees. 

It’s important to note that not all fungicides are tree-safe. Always check the fungicide’s label to ensure it won’t harm the tree before application.
