Most Common Symptoms of an Unhealthy Tree and Solutions

The trees are sick. Like any other living thing, a tree can get sick for various reasons. If left unmanaged, they can be left astray and lose the right path. Suppose a healthy tree otherwise shows signs of illness or disease. In that case, you should take action to eliminate the cause or look for a tree disease specialist to inspect the tree and provide a course of action. Old trees can catch paralysis and rot if you are looking for a tree disease specialist so that your trees can get the most care and stay healthy. Trees contribute significantly to the value of the area, so it is important to keep them healthy.


Anthracnose is a common disease among decaying trees, especially sycamore, ash, and oak. It also affects shrubs such as privet. It creates dark, dead sores on the leaves, stems, flowers, and fruits. Anthracnose fungi need water to spread and become infected, so the disease is most common among wet, cold sources. Because it is a cosmetic problem, the tree has a serious health risk, and anthracnose usually does not need treatment. 

Other cultural practices can help prevent this, including collecting and disposing of leaves and twigs and increasing air circulation by pruning infected branches and branches while the tree is sleeping. Taking care of your trees will help them grow faster.

Scabs of Apple Plants:

Apple scab is a common disease of apple and crab trees and mountain ash and pear. This scab is caused by the fungus or bacteria that directly attacked the plant’s leaves, branches, and fruits. At the initial stage of the disease, leaves start changing their color and eventually turn brown. In the same way, the fruits infected by the disease change their color too. There are several solutions for this disease. You can consult with experts for a variety of scab-resistant apple plant types. Fungicides can also be applied to healthy trees to avoid scabs in the future.

Canker Diseases:

Various diseases affect trees, including Cytospora canker on pine, poplars, spruce, and willow. This disease is caused by bacteria or pathogens attacking the tree’s bark or wood from the wounded side. And, after some time, it completely blocks the vascular system and nutrient supply of trees. 

Depending on the location of the canker, this blockage can result in the death of the branches. Pressured trees are vulnerable to natural features, animal browsing, mechanical damage, etc. Preventive measures include growing trees suitable for the environment and conditions, preventing bark damage, proper care, and winter protection, and removing any cancerous branches. The bleach solution reduces pruning tools of canker trees between tree cuts.

Cedar-Apple Rust:

As the name implies, the cedar-apple rust is a fungus that needs two armies to complete its life cycle: In its two-life cycle, the fungus spends its first annual cycle in cedar, and in the spring season, its grains are carried out by the wind and help them to enter their second life cycle. It can be within one mile around the tree or plants. The disease causes bright yellow-orange spots on leaves and fruit and swollen bodies that bear fruit on stagnant branches. Due to rusting, leaves and fruits may fall before maturity. For the treatment, fungicides are applied to the apple cedar trees during spring to avoid rusting.

Fire Blight:

Fire damage leaves a myth report card: tree branches look like they have been set on fire, and withered leaves turn black. Fire blight attacks the branches from time to time so that you may see dead leaves in various parts of the plant. It is especially useful in warm, humid climates. To control fires, make sure you cut back to non-infected wood. Remove sterile tools during cuts in a 10 percent bleach solution. Fruit trees are the main victims of fire damage, but there are steps you can take to keep your fruit trees healthy.

Oak Wilt:

The most common disease of fungus affects oak trees. There are several families of these plants. Some are easily affected by fungus, and others are not. They quickly turn brown after getting the disease. This disease can also be transferred from one tree to another tree of generation. This disease can be avoided by avoiding cutting trees during the growing season, and if you have done this, use wound cover of trees to avoid infection.

Powdery Mildew:

It is a disease in which trees are covered with white powder. That white powder infects the tree’s leaves and turns them yellow, and eventually, leaves start falling in the growing season. It is caused by a dangerous fungus and badly harms the trees. To control this disease, plant those varieties resistant to this disease also plant them in the fresh air, but fungicides can also be used for treatment.

Phytophthora Root Rot:

The type of fungus attack infects the trees that grow in shady places. It made the tree look dry, and the leaves turned yellow and brown. This disease has no cure, but there are certain remedies to prevent them. You can control it by avoiding planting trees in wet areas and shadowy places. Or you can select the varieties of plants that are water-loving. Use covers and avoid planting them too deep.


So, here are some common symptoms of unhealthy trees and their solution. If you are looking for a tree disease specialist, check this guide for improvement.
