Troubleshooting
Chalice Vine problems — and how to fix them
Chalice Vine (Solandra grandiflora) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Failure to bloom
Most often caused by insufficient direct sun, excess nitrogen, or overly warm nights. Ensure at least 6 hours of full sun and apply a potassium-rich fertiliser in late spring. A brief cool period (down to 15°C) in winter can trigger flowering.
Scale insects
Soft or armoured scale can colonise stems and leaf undersides, causing yellowing and sticky honeydew. Treat with horticultural oil spray or systemic insecticide; repeat every 10–14 days until clear.
Root rot
Caused by waterlogged soil, especially in winter. Ensure pots have drainage holes, use a free-draining mix, and reduce irrigation during cooler months. Affected plants show wilting and brown roots.
