Troubleshooting
Camellia 'Jury's Yellow' problems — and how to fix them
Camellia 'Jury's Yellow' (Camellia x williamsii 'Jury'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.
Yellow colour fading
The primrose-yellow petaloids fade quickly in strong sunlight; grow in partial shade to preserve the colour display for as long as possible.
Bud drop
Less common in williamsii hybrids than japonicas, but prolonged autumn drought or root disturbance can still cause losses; water steadily from August.
Chlorosis
Pale, yellowing leaves result from alkaline soil; apply sequestered iron and acidify with ericaceous compost mulch.
Petal blight
Ciborinia camelliae causes brown, soggy patches on open flowers; collect fallen blooms daily and do not compost them.
Scale insects
Apply horticultural oil in spring to manage scale; check undersides of leaves and stem junctions for colonies.
