Troubleshooting
Camellia 'Dixie Knight' problems — and how to fix them
Camellia 'Dixie Knight' (Camellia japonica 'Dixie Knight') 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
A sudden drop of buds in winter usually indicates drought stress the previous summer. Mulch generously and water consistently from July to September.
Petal blight
The large, densely petalled blooms can trap moisture and succumb to Ciborinia petal blight in wet springs. Pick off affected flowers immediately.
Chlorosis
Iron and manganese deficiency from high pH causes yellowing between leaf veins. Correct with sequestered iron and rainwater irrigation.
Frost damage to flowers
Crimson flowers show frost damage readily as browning on petals. Site away from east-facing frost pockets and protect with fleece during severe frosts.
Vine weevil
Container specimens are vulnerable; apply nematodes in late summer. Brown-edged notching on leaves is the giveaway sign of adult weevil presence.
