Lilium 'Casa Blanca' problems — and how to fix them
Lilium 'Casa Blanca' (Lilium 'Casa Blanca') 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.
Scarlet lily beetle
Red beetles and sticky larvae quickly strip leaves and buds. Check plants regularly from spring and remove pests by hand or treat.
Pollen staining
The large rust-coloured anthers shed pollen that stains clothing, petals and surfaces. Remove anthers from cut stems with care.
Botrytis blight
Brown blotches on leaves and rotting buds in cool, wet, crowded conditions. Improve ventilation, water at the base and clear infected debris.
Bulb rot
Wet, heavy soil causes bulbs to rot and plants to fail to emerge. Plant on grit in free-draining soil or use gritty compost in containers.
