What goes wrong with Carpinus
| Problem | What you'll see | What to do |
|---|---|---|
| Aphids | Clusters of small insects on new growth; sticky honeydew on leaves. | A strong spray of water can dislodge them. Use insecticidal soap for heavier infestations. |
| Two-lined Chestnut Borer | Dieback at the top of the tree, D-shaped exit holes on the trunk. | Keep tree healthy and unstressed. Systemic insecticides may be required for treatment. |
| N/A | This tree is remarkably free of serious insect pests. | Monitor for general pests but treatment is rarely required. |
| Two-Lined Chestnut Borer | Branch dieback starting from the top of the tree, D-shaped exit holes. | Keep trees healthy and unstressed. Prune and destroy infested limbs. Systemic insecticides can be used preventatively. |
| Canker | Sunken, dead areas on branches or trunk. | Prune out infected branches well below the canker. Avoid wounding the tree. |
| Leaf Spot | Brown or black spots on leaves, sometimes causing minor defoliation. | Generally cosmetic. Rake up and destroy fallen leaves. Improve air circulation. |
