Tree diseases are not only reflected in the condition of a plant's leaves. The bark of the maple tree can also tell you something about its he alth. This is how you can recognize and treat diseases on the maple tree in good time.
Which tree diseases can be identified on the maple bark?
Black spots on the maple bark indicate sooty bark disease, red pustules indicate red pustule disease and wrinkles indicate dryness or wilt disease. Treatments include removing affected parts, applying wound closure products, or checking the soil for moisture.
What do black spots on the bark of the maple mean?
A dark, sooty fungal coating and a possible mucilaginous stain on the bark of the maple indicateSooty bark disease. In this case it is an infestation with fungal spores. The tree disease mainly affects sycamore maple, partly also Norway maple and field maple. It typically occurs in hot summer months. In this case, it is best to hire a professional. Since the spores can cause allergic reactions and inflammation of the alveoli, you should only approach the spore deposit with professional protective equipment.
Why does the maple tree have red pustules on its bark?
Pin-sized red dots on the bark of the maple indicate red pustule disease. The distinctive color means you can quickly recognize this tree disease. It is also caused by a fungus that works its way through the tree. If you don't take action, this tree disease causes cancerous ulcers on the maple trunk. As a rule, this fungus only affects the maple tree if there are errors in care or certain problems with the location. How to treat the tree:
- Cut out affected parts generously.
- Apply wound closure agent.
Why does the bark of the maple become wrinkled?
Wrinkled bark can indicate dryness or be a harbinger of the dreaded wilt disease. When wilting occurs, the branches initially sprout completely normally. The leaves then wilt and parts of the plant dry up for no apparent reason. Checking the moisture in the soil can help you determine whether the maple may simply be suffering from drought rather than a tree disease. Lack of water and drought stress can also affect the bark of the maple tree.
Tip

When planting, choose a location that is as suitable as possible for the respective maple variety. If all of the tree's needs are well served, the tree will not catch a tree disease so quickly.
