If a tree on your property is diseased, it can pose a problem for your property. After all, diseased and weakened trees can be a safety risk, especially during the winter months or periods of inclement weather. It’s important to keep an eye on the trees on your property in order to make sure there are no health or safety hazards posing a risk to your family, friends, and neighbors. If a tree on your property is sick, it will require the proper tree care in order to prevent safety issues and encourage healthy plant growth on your property. Here are the top signs that your trees may be sick.


If you have oak trees on your property, it’s a good idea to routinely check the tree’s base for fungal growth. There is a common type of fungus that affects oak trees by stunting branch growth and causing the tree to weaken. To spot this fungus, look for brown shelves along the base of the tree. If you spot this shelving, be sure to call a tree care professional, as the tree can be in danger of falling soon after the warning signs are visible.


Mildew can be a problem for just about any type of tree. This will often develop after periods of high humidity as spots of powdery white spots. Mildew is often a sign of disease in trees that can distort the shape of leaves and stunt the tree’s growth.

Fluid Seepage

One sure sign of disease in a tree is seepage of slime-like fluid. Check your trees for pools of slimy liquid at the base or dark streaks along the bark. These can be signs that your tree is seeping fluid and may require professional tree care.

Discolored Leaves

While many of us look forward to the colors of leaves changing in the fall, this can also be a sign that your trees are sick. Look for green leaves turning yellow or brown during the summer months, as this can be a sign that a tree is suffering from root rot.

Peeling Bark

Bark is the tree’s outermost layer of protection from the elements. This can keep your tree safe from boring insects or harsh weather, so peeling bark or bare patches on your tree can be a sign that the tree is vulnerable. Have trees with peeling bark inspected to ensure they are healthy.
