What goes wrong with Agapanthus
| Problem | What you'll see | What to do |
|---|---|---|
| Aphids | Sticky residue and distorted leaves | Spray with insecticidal soap organic option |
| Agapanthus Gall Midge | Flower buds become deformed, discolored, and fail to open. Small maggots may be found inside. | Remove and destroy affected flower heads immediately. There is no effective organic control. Systemic insecticides like acetamiprid may offer some protection if applied before budding. |
| Mealybugs | White cottony masses on stems | Apply horticultural oil or remove manually |
| Snails | Chewed leaves and slime trails | Apply iron phosphate bait or handpick |
| Root rot | Yellowing leaves and wilting | Improve drainage and reduce watering |
| Root Rot | Yellowing leaves, wilting, and a mushy crown, caused by overly wet soil. | Prevention is key. Plant in well-draining soil or containers. Allow soil to dry out between waterings. If rot occurs, repot into fresh, dry soil, removing any rotted roots. |
| Leaf spot | Brown spots on foliage | Remove affected leaves and apply copper fungicide |
