Troubleshooting
white double camellia problems — and how to fix them
white double camellia (Camellia japonica 'Alba Plena') 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.
Petal browning
White flowers are particularly prone to browning from frost, rain, or direct sun. Site in a sheltered position facing east or north, and avoid overhead watering onto open blooms. Dead-head promptly to maintain appearance.
Bud drop
Buds develop through summer but fall without opening due to drought stress, irregular watering, or being moved during bud set. Maintain consistent moisture from July onwards and avoid relocating container plants once buds are visible.
Scale insects
Brown soft scale (Coccus hesperidum) and cushion scale colonise stems and the undersides of leaves, causing sooty mould and weakening the plant. Treat with plant oil-based insecticide or systemic neonicotinoid-free alternatives in late spring; scrub stems with a soft brush.
