Troubleshooting
Camellia 'Debbie' problems — and how to fix them
Camellia 'Debbie' (Camellia japonica 'Debbie') 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.
Bud drop
Caused by irregular watering, drought stress during bud development, or sudden temperature fluctuations; water consistently through autumn and avoid moving container plants.
Lime-induced chlorosis
Yellow leaves with green veins indicate iron or manganese deficiency due to high soil pH; apply sequestered iron chelate and switch to rainwater.
Scale insects
Brown scale on stems and leaf undersides; treat with horticultural oil or neem oil in late spring when crawlers are active.
Camellia petal blight
Brown, water-soaked patches on flowers caused by the fungus Ciborinia camelliae; collect and destroy fallen flowers promptly to break the disease cycle.
Sooty mould
Black coating on leaves caused by honeydew from scale or aphids; control the underlying pest and wipe leaves clean with a damp cloth.
