Tree Diseases to Look Out For

We are constantly bombarded with messages reminding us to keep care of ourselves. How many times are we reminded to go to the doctor? Watch out for warning signs of certain health conditions? We are told to constantly keep our health at the forefront of our minds — and for good reason. Healthy bodies look better and perform better.

That same logic applies to our trees. Yes, really. A healthy tree looks better and is able to last the test of time. You may not have known that our trees can contract a variety of diseases that can potentially kill them — wasting many years we may have spent cultivating them to grow healthy and strong.

Whether you’re an avid gardener or have never each touched a planet in your life, take a look at some common tree diseases you should keep your eye out for. Recognizing these diseases is key to maintaining a beautiful and healthy lawn.


Anthracnose is one of the most common tree diseases around. It is derived from fungi that target twigs, leaves, and flowers of many tree species. However, the tree species most vulnerable to anthracnose are the sycamore and flowering dogwood.

The symptoms of anthracnose vary depending on what pathogen, in particular, is attacking your tree. The most common symptoms are premature defoliation of leaves. Ultimately, this fungus can result in the death of the tree.

Fire Blight

This is a disease largely caused by bacteria, mainly affecting apple and quince trees. If your tree has been infected with fire blight, you’ll notice that its blooms suddenly blacken and then become both brittle and dry.

Other symptoms include tips that begin to resemble a shepherd’s hook, as well as black twigs and branch cankers. If you see any of these, you may have a case of fire blight on your hands — well, your tree.

Apple Scab

As you might have guessed by its name, this disease many affects crabapples, so if you have a crabapple tree in your backyard — you may want to pay extra careful attention. You’ll notice scabs on your crabapples, which will eventually cause premature defoliation in your infected tree. However, most of the damage that apple scab causes your tree is mainly aesthetic issues — it won’t affect the tree much in the long term, for the most part.

Diplodia tip blight

The name of this disease is certainly a mouthful. Pine trees are especially prone to developing diplodia tip blight, a disease that usually starts from the bottom of the tree and steadily makes its way up. You’ll notice the needles on your pine tree turn brown and fall off.

If you notice your trees aren’t looking as healthy as usual, you should consider reaching out to a tree specialist like Hamlin Tree Care. They’ll be able to identify was disease your plant is suffering from and recommended the best course of treatment. In fact, they may be able to administer the treatment themselves.
