How to Identify Common Tree Diseases

Tree Diseases

Be vigilant when looking out for these tree diseases that could spell trouble.

Spring has finally sprung, so it is time to get back outside and start enjoying nature again. Springtime means that trees will start budding and blooming again, signalling new life and a healthy outlook on the rest of the coming year. As a homeowner, you owe it to yourself to get outdoors and enjoy your property as the weather begins to get better and better. Healthy trees are a great benefit and addition to any outdoor space, but if the trees on your property are unhealthy or diseased, they prove to be a serious risk to your home and family. Keep reading to learn some common signs of tree diseases so that you can take care of those problems before they become unmanageable.

Leaf Rust

If one of your trees has leaf rust, then it will have a distinct spotting pattern on its leaves. Keep an eye out for orange or red leaves, especially when it occurs in seasons other than autumn.

Leaf Spot

Similar to leaf rust, leaf spot can cause strange discolorations in your trees’ leaves.

Fire Blight

This disease often gives a tree a burned look on its bark and leaves.

Powdery Mildew

To ensure a tree’s health, check leaves for signs of damage or strange discolorations that look unnatural. If leaves are dusty or white, your tree may have a dusty mildew problem.


Gall is actually a specific type of fungus that tends to grow on tree trunks or branches of older trees.

Japanese Beetle Infestation

Japanese beetles are an invasive species to North America. They are insects that tend to feed on leaves of deciduous trees. Look out for Japanese beetles by looking for bugs with a brown thorax.

Emerald Ash Borers

Like Japanese beetles, emerald ash borers are also insects that can seriously affect your trees. They are bright green and can kill an entire mature tree.


Bagworms can be spotted by looking for their white, spidery nests in the branches of your trees. They house grub insects that feed on older tree leaves and branches. Gross!
