What could be causing small holes in the upper side of maple tree leaves causing them to turn brown and curl up as if they are drying out?
Maple trees are susceptible to a number of pests and diseases that can cause holes in the leaves, causing them to turn brown and curl up as if they are drying out. Some of the most common causes of these symptoms include:
- Insects: Several species of insects, such as aphids, lace bugs, and leaf miners, can feed on maple leaves, causing small holes to form. These holes can then allow bacteria and fungi to enter the leaves, causing them to turn brown and curl up.
- Diseases: Fungal diseases, such as anthracnose and powdery mildew, can also cause holes to form in maple leaves. These diseases can also cause the leaves to turn brown and curl up.
- Environmental factors: Drought, heat, and wind can also cause maple leaves to turn brown and curl up. These factors can damage the leaves, making them more susceptible to pests and diseases.
If you are concerned about the health of your maple tree, it is important to consult with a certified arborist. They can help you identify the cause of the problem and recommend the best course of action.
