Troubleshooting
Camellia 'Brushfield's Yellow' problems — and how to fix them
Camellia 'Brushfield's Yellow' (Camellia japonica 'Brushfield's Yellow') 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
Drought stress during late-summer bud formation is the primary cause. Maintain consistent soil moisture and apply a deep bark mulch.
Chlorosis
Yellow leaves indicate lime-induced iron or manganese deficiency. Apply chelated iron and use rainwater for irrigation.
Petal blight
Brown spots on petals in wet springs spread rapidly. Remove affected flowers promptly and clear all fallen petals.
Slow growth / poor flowering
This cultivar is naturally slow-growing. Ensure correct pH and adequate feeding; root disturbance can set flowering back by 1-2 years.
Scale insects
Can infest older wood; treat with horticultural oil in summer when crawlers are active.
