Troubleshooting
Camellia 'Kramer's Supreme' problems — and how to fix them
Camellia 'Kramer's Supreme' (Camellia japonica 'Kramer's Supreme') 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
Moisture stress or root zone disturbance in autumn is the most common trigger; water consistently and avoid repotting container plants after buds form.
Botrytis on peony blooms
The dense petal clusters of peony-form flowers trap moisture; improve air circulation and remove spent blooms before they rot.
Camellia scale
Flat, brown-grey scale insects on stems and leaf undersides; apply horticultural oil spray in spring when crawlers are active.
Chlorosis
Iron deficiency in neutral to alkaline soils causes interveinal yellowing; apply sequestered iron chelate and switch to rainwater irrigation.
Frost damage to flowers
Red flowers show less colour-fade from frost than white or pink cultivars, but a fleece cover on forecast frost nights protects open blooms from browning.
