5 Common Types Of Tree Diseases

Trees are an essential part of our environment, which help in enhancing the aesthetics of our yards and keeping our environment free of pollution.

Trees are living beings and like all living things, require care and attention. Lack of care can result in trees becoming susceptible to diseases. These diseases can affect the health of the tree or damage it to a point where you have no choice but to remove it altogether.

These diseases are not just limited to your yard. They can spread and cause several health problems for homeowners.

You can avoid these problems by identifying the signs of tree diseases. Here are five most common types of tree diseases.


This is a disease, which occurs when a group of fungi targets the leaves, flowers, twigs, and the fruits of your tree. The symptoms of the disease are different and depend on the hosts and pathogens. Some symptoms of this disease include:

  • Leaves dying or turning spotty
  • The foliage starts falling during the later stages of Summer
  • Reduction in the rate of growth

This disease results in dead branches and the death of the tree.

Apple Scab

This is a leaf disease that affects crabapples. You can identify this if there is a formation of scab like lesions on leafs of your tree. This disease causes leaves to fall.

Oak Wilt

This is a systematic fungal disease, which can result in the death of your tree. Infected beetles transmit this disease to the tree through the root grafts.

You can identify if your tree has this disease by the following symptoms:

  • Wilting
  • Leaves rapidly losing color
  • Leaves falling
  • The veins of the tree turn yellow and then brown

Thousand Canker Disease

This disease specifically attacks Walnuts. Walnut twig beetles are responsible for infecting the trees with this disease. These insects form cankers on the tree. Over time, the cankers start accumulating over branches and stems.

It takes a long time for the tree to show signs of this disease. When a tree has this disease, the leaves in the upper branches turn yellow and there is a decline in tree wilt.

Powdery Mildew

The fungal pathogens, which grow on the surface of the plant and produce fungal threads known as White Mycelia and spores are responsible for causing the disease known as Powdery mildew.

The fungus attacks the young tissue, which results in the stunting of, leafs and the flowers. As the fungus gets more powerful, the tissue turns brown and dries up. It also results in the loss of leaves.

The disease also prevents the growth of flowers.
