Troubleshooting
Camellia 'Water Lily' problems — and how to fix them
Camellia 'Water Lily' (Camellia x williamsii 'Water Lily') 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
Usually caused by drought stress during bud development in summer and early autumn, or by frost damage to developing buds. Water consistently and protect buds from hard frosts with fleece.
Petal blight (Ciborinia camelliae)
Causes brown blotches that spread rapidly across petals in wet spring weather. Remove affected flowers promptly and do not compost them; improving air circulation helps.
Yellowing leaves (chlorosis)
In hard-water areas or alkaline soil, iron and manganese become unavailable. Apply sequestered iron and water with rainwater. Repot containerised specimens with fresh ericaceous compost every 2-3 years.
Scale insects
Soft and hard scales can build up on stems and the underside of leaves. Treat with a horticultural oil spray in summer or apply a systemic insecticide if severe.
Frost damage to flowers
Avoid east-facing planting; early morning sun thaws frosted petals too quickly, causing browning. Wrap buds in horticultural fleece if sharp frosts are forecast during blooming.
