Sunsatia Plus Coconut Nemesia problems — and how to fix them
Sunsatia Plus Coconut Nemesia (Nemesia fruticans) 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.
Root rot in waterlogged conditions
The shrubby root system is vulnerable to prolonged wet soil; ensure excellent drainage and reduce watering in cool, cloudy periods.
Aphids
Soft new growth attracts aphid colonies; apply insecticidal soap at first sighting before populations establish.
Powdery mildew
Pale powdery patches on leaves in warm, dry or humid weather; treat with dilute sodium bicarbonate spray and thin congested growth.
Legginess after first flush
Cut plants back by up to one-third after the first main flowering to encourage a compact second flush of blooms.
Winter dieback in cold climates
Frost-tender in UK winters outside zone H3; take cuttings in late summer and overwinter young plants frost-free as insurance.
