Troubleshooting
Camellia 'Alba Plena' problems — and how to fix them
Camellia 'Alba Plena' (Camellia japonica 'Alba Plena') 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 at bud set, or root disturbance; maintain steady moisture from late summer through spring without waterlogging.
Petal browning from frost
Open white blooms are easily damaged by late frosts; protect with horticultural fleece on forecast frost nights or site against a south-west facing wall.
Petal blight (Ciborinia camelliae)
Brown patches spread across flowers rapidly in wet springs; collect and bin all fallen flowers immediately and avoid soil-level watering.
Iron chlorosis
Pale, yellowing leaves with dark veins indicate iron or manganese deficiency; correct with sequestered iron and avoid lime-rich water or topdressings.
Scale insects
Brown or white scale on undersides of leaves and stems; treat with horticultural oil applied in spring when crawlers emerge.
