10 Common Tree Diseases: Recognizing the Signs

Almost every homeowner would love to have a property surrounded by lush greenery and tall trees. But that dream can become derailed if your trees fall victim to disease. Not only can these diseases often be spread from tree to tree, but they can also pose a safety threat to your property. As diseased trees weaken, they could potentially fall onto your home or cause injury to someone you love.

As a result, you’ll want to learn how to recognize the signs of the most common tree diseases. And if you do spot them, you’ll want to conduct an internet search for “tree removal companies near me” right away. Here’s what you should keep an eye out for when inspecting your property:

  1. Dusty Leaves: Take a close look at the leaves on your trees. Do they seem to be covered in a white powder? If snow is out of the question and it looks like the tree has been dusted with flour, it could be powdery mildew. This fungal disease can take away a plant’s nutrients and make it much harder for the tree to thrive.

  2. Torched Trees: If some of your trees’ leaves look as if they’ve been held up to a flame, you could be dealing with fire blight. This is a contagious disease that often affects fruit trees. When a tree looks like it’s been torched and you know there hasn’t been a blaze nearby, you’ll want to Google “tree removal companies near me” to obtain guidance.

  3. Rust Spots: Leaves aren’t made of metal, so they can’t actually rust. But a parasite known as leaf rust can cause circular marks (or pustules) to form on a tree’s leaves. A quick glance might make you think it’s merely time for the foliage to turn. However, you’ll want to take action to ensure the problem doesn’t get worse.

  4. Tumor-Like Growths: Have you noticed an odd growth forming on a tree trunk or branch? It could be what’s known as gall. In some cases, it can even form on leaves. This fungus can destroy trees if left unaddressed, so you won’t want to delay in calling an expert.

  5. Tree Cankers: Much like sores that might develop on our skin, unsightly cankers can appear and blemish the trunk of a tree. They typically show up on isolated dead areas of a tree, like on branches, twigs, or bark. Because cankers can make a tree even more vulnerable to bacteria, insects, fungus, and damage, it’s essential to call a professional when this sign is spotted.

  6. Branch Deformities: Often called “witch’s broom,” a common tree deformity is marked by major changes in branch structures wherein many shoots grow from a single point. The result looks like a bird’s nest or a broom. Fungi, insects, and viruses can cause this problem, though sometimes human error (like over-pruning) can also be to blame.

  7. Japanese Beetles: These highly invasive insects can spell disaster for a tree. These bugs resemble brown-colored ladybugs, but they can do an immense amount of damage. While there are insecticides available that can lessen the issue, you might lose some of your favorite trees and plants if you don’t obtain expert help.

  8. Black Blemishes: A condition known as leaf spot can also harm your trees. Caused by fungi or bacteria, these circular and dark blemishes can be found on leaves. Although it’s usually more of a cosmetic problem than anything else, you’ll want to do what you can to keep it from spreading.

  9. Bagworms: Unfortunately, beetles aren’t the only creatures who like to munch on your landscaping. Bagworms, which are actually caterpillars, tend to feed on the branches and leaves of mature trees. They get their name from the “bags” they create — which can hold up to 1,000 eggs. These bags can also be found on your tree branches, so you’ll need to get rid of them before they hatch.

  10. Emerald Beetles: There are a number of insects who can do harm to your trees — and the emerald ash borer is another example. These jewel-green bugs belong to an invasive species that will feed on ash trees and destroy them. In fact, this beetle has singlehandedly led to the destruction of hundreds of millions of these trees in at least 35 different states.
