Troubleshooting
Lupinus 'Chandelier' problems — and how to fix them
Lupinus 'Chandelier' (Lupinus 'Chandelier') 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.
Lupin aphid
Distinctive large grey aphids swarm spikes and sap vigour. Catch early and wash off or treat; unchecked colonies distort and collapse the flower stems.
Powdery mildew
Common on tired foliage after bloom in dry, still air. Deadhead, water at soil level, and space plants for ventilation to slow the spread.
Crown and root rot
Heavy, wet soils rot the crown over winter. Provide gritty, free-draining soil and avoid sites that stay waterlogged.
Lime-induced chlorosis
Pale, yellow-veined leaves indicate the soil is too alkaline. Lupins need neutral-to-acid conditions; acidify chalky soil or grow in raised, free-draining beds.
