6 Signs That a Tree Has a Disease

» Posted by on Jan 15, 2018 in Tree Disease | 0 comments

Most of us don’t know how to spot a diseased tree. We can’t blame ourselves because the first signs of a dying or diseased tree are not noticeable. Sometimes we would know that it’s already dead when the signs are really visible to our eyes. We wouldn’t know until the professionals perform a large tree removal because of the disease. So we are sharing with you signs of tree diseases to avoid the trees from dying and incurring damages to our properties.  


Hard, Gray Growths 

If your tree has a hard, hoof-shaped structure which is of gray color, your tree has a fungus named fomes fomentarius. This fungus often damages trees like Cherry, Hickory, Birch and Maple. On the bottom of the fungus, it has millions of tiny and white pores. Once the fungus attaches to your tree, it grows big until you remove it.  

Seeping Fluid 

If there’s a fluid seeping from the tree, it means that it has an alcoholic slime faux. If the case is already extreme, you would notice excess fluid pooling in the tree’s base. The fluid will leave some dark streaks in the bark of the tree and often has a sour odor. Most of the trees with this disease will produce fluid in summer and spring.  

Peeling Bark 

Another sign of a diseased tree is when it the bark is peeling. The tree’s bark is an essential part of your tree; it protects the inner core of the trunk keeping the tree healthy. If you notice the bark starting to peel, the trees could die because it can’t maintain the necessary nutrients it needs. But don’t be alarmed if you see small peeling bark because it’s normal for some trees. Be alarmed if the peeling bark is a large piece. When this happens, call a tree professional right away.  

Light Brown Shelves Near the Tree’s Base 

Another fungus that can affect the trees is the inonotus dryadeus. The fungus impedes the growth of the branches once it affects the tree. Once the fungus will reach the tree’s base, it forms a large brown shelf near the ground. This shelf will harden overtime and turn black. If you see this sign in your trees, you should have it removed before it falls off and affects your property.  

Black Flower or Shoots 

One of the most common diseases of a tree is fire blight. You will know that your tree has this disease once its shoots or flowers turn black. Once they are infected, they will bend into the shepherd’s crook shape. This signs and shapes will appear a few weeks after the infection. The bacteria doubles in population once the disease enters the system of the trees.  

Yellow or Brown Leaves 

Another sign of a diseased tree is the browning or yellowing of the leaves. If it’s coupled with slowed growth, this is because of armillaria root rot. You will notice major branches will wilt and die once they have this disease. The fungus in the soil rots attacks the tree’s roots which then lead to this disease.
