What goes wrong with Populus
| Problem | What you'll see | What to do |
|---|---|---|
| Poplar Borer | Holes in the trunk and branches, often with sawdust-like frass. | Maintain tree vigor with proper watering. Chemical controls like permethrin can be applied to the trunk during egg-laying season. There is no organic cure. |
| Aphids | Clusters of insects on new growth, sticky honeydew, and sooty mold. | A strong spray of water can dislodge them. Encourage beneficial insects. Use insecticidal soap for heavy infestations. |
| Oyster Shell Scale | Small, gray, oyster-shaped bumps on the bark. Heavy infestations can cause branch dieback. | Apply dormant horticultural oil in late winter to smother overwintering scales. Use targeted insecticides when crawlers are active in late spring. |
| Cytospora Canker | Sunken, discolored areas on bark (cankers) that ooze resin; causes branch dieback. | Prune out and destroy infected branches in dry weather. Disinfect tools. There is no chemical cure; focus on preventing stress. |
| Leaf Rust | Orange or yellow pustules on the undersides of leaves in late summer. | 'Siouxland' is resistant. For other poplars, rake and destroy fallen leaves. Fungicides are rarely necessary for landscape trees. |
| Hypoxylon Canker | Yellowing leaves, dieback, and distinctive black, crusty fungal bodies on bark. | No cure. Prune out affected branches. Prevent by maintaining tree health and avoiding drought stress. |
