What goes wrong with Liriodendron
| Problem | What you'll see | What to do |
|---|---|---|
| Tulip Tree Scale | Gray, crusty bumps on twigs and branches, causing branch dieback. | Apply dormant horticultural oil in late winter. Use a systemic insecticide for heavy infestations. |
| Tulip Tree Aphids | Sticky honeydew dripping from leaves, often leading to sooty mold. | Release ladybugs or lacewings. Spray with insecticidal soap or use systemic insecticides like imidacloprid for severe cases. |
| Tulip Tree Aphid | Large colonies on leaf undersides produce copious sticky honeydew, leading to sooty mold. | Often controlled by natural predators; spray with horticultural oil or insecticidal soap; systemic insecticides for severe cases. |
| Verticillium Wilt | Sudden wilting, yellowing, and dieback of one or more branches. | Prune out infected branches. Improve soil drainage and avoid high-nitrogen fertilizers. There is no chemical cure. |
| Powdery Mildew | White, powdery patches on leaves, especially in late summer. | Ensure good air circulation. Apply horticultural oil or a fungicide containing potassium bicarbonate. Chemical fungicides can also be used. |
