Troubleshooting
Camellia 'Hagoromo' problems — and how to fix them
Camellia 'Hagoromo' (Camellia japonica 'Hagoromo') 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
Erratic watering during late summer bud set is the most common cause. Mulch deeply and maintain consistent soil moisture from July onwards.
Petal blight
Brown patches rapidly spread over petals in wet springs. Remove affected flowers immediately, clear fallen petals, and avoid overhead irrigation.
Chlorosis
Yellow leaves with green veins indicate iron or manganese deficiency from high pH. Apply sequestered iron and switch to rainwater irrigation.
Vine weevil
Grubs are particularly damaging to container-grown camellias. Apply nematode treatments (Steinernema kraussei) in late summer and early autumn.
Aphids on new growth
Soft new shoots in spring can attract aphids. A jet of water or insecticidal soap spray is usually sufficient to control them.
