Adolphe Audusson camellia problems — and how to fix them
Adolphe Audusson camellia (Camellia japonica 'Adolphe Audusson') 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
The most common complaint — buds form in summer but fall before opening. Caused by irregular watering during July–September bud set, sudden temperature fluctuations, or root disturbance. Maintain consistent moisture and avoid moving the plant while buds are forming.
Yellow leaves (chlorosis)
Yellowing between leaf veins (interveinal chlorosis) indicates iron or manganese deficiency caused by alkaline soil or hard water. Switch to rainwater, apply sequestered iron chelate, and re-pot into fresh ericaceous compost if container-grown.
Camellia leaf gall (Exobasidium camelliae)
Pale green or pinkish fleshy galls develop on young leaves in spring. Remove and destroy affected growth immediately; do not compost. Improve air circulation by selective pruning. No fungicide is generally needed if galls are caught early.
