Tree Diseases

There are many benefits to ensuring the health of your trees. Infected trees often have weak limbs, which can break and fall during a storm or in the winter. They can also pose a risk to neighboring plants and trees, threatening the health of your entire yard. It is essential to act quickly when you have a tree in distress. Our arborists at Dunbar Tree Service can effectively identify the issues affecting your trees, then recommend and implement treatment.

Many different types of tree diseases and fungi can have devastating effects on your trees. Various microorganisms such as fungi and bacteria can significantly damage and lead to the swift deterioration of the health of your trees.  There are also other factors such as environmental stress. These include droughts, excessive moisture, temperature extremes, and even polluted air.

Diagnosing Tree Diseases

Preventing, detecting, and managing tree diseases can be crucial in maintaining the health of your yard. Often, an arborist can catch potential problems in an inspection. However, while preventative care can help keep your trees from getting sick, sometimes they become diseased on their own. That’s when contacting an arborist for diagnosis is essential.

Diagnosing the problem is step one to curing any sick trees on your property. But tree diseases can be very difficult to diagnose. This is because many different diseases and environmental factors can have similar symptoms, much like symptoms of a viral or bacterial infection in people. In addition, your trees could be affected by more than one factor.

Trees can be experiencing a fungal infection while also being affected by environmental factors. This can complicate the process of identifying tree diseases and treating them. This is why it is so important to work with a company with professional, experienced arborists on staff. If you have an issue with your trees, call Dunbar Tree Service and let our certified arborists evaluate your problem trees.

Common Signs of Tree Diseases

You are the first line of defense for your trees. Identifying a problem with your trees can be done with a quick inspection if you know the signs.

The first step is to look at the trunk of the tree. You may notice some discoloration or scabs on the bark. You may also notice a fungus growing on the bark of the tree or on exposes roots. Next, you can check for excessive moisture or sogginess around the trunk of the tree. This can indicate root rot.

Then, the branches of the tree should be inspected. You may see a dusty coating on the branches. Finally, you can look at the tree’s leaves. If you notice abnormal growth, wilting, excessive dryness, discoloration, and/or patches of bare branches where there has been a large amount of “die-off” of the leaves, then it is a sign that there is something wrong with the tree.

All of these are signs that it’s time to call in a professional to identify and take care of the problem.
