Troubleshooting
Japanese Camellia problems — and how to fix them
Japanese Camellia (Camellia japonica) 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
Buds form but fall before opening, usually from dryness at the roots in late summer or sudden temperature swings. Water consistently from midsummer and mulch to keep the root zone moist.
Brown, scorched flowers
Early-morning sun on frosted blooms thaws them too quickly. Plant where morning sun does not strike the flowers and avoid cold, exposed east-facing sites.
Leaf yellowing (chlorosis)
Yellow leaves with green veins signal alkaline soil or hard water locking up iron. Use ericaceous compost, water with rainwater, and apply sequestered iron if needed.
Camellia petal blight and scale
Brown rotting petals indicate petal blight; clear fallen blooms to reduce spread. Sooty mould on leaves points to scale insects, which can be wiped off or treated.
