Red Iochroma problems — and how to fix them
Red Iochroma (Iochroma fuchsioides) 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
Moving the plant during bud development, low humidity, temperature fluctuations, or draughts frequently causes developing flower buds to abort. Choose a stable, draught-free position with 60%+ humidity and avoid repositioning once buds appear.
Aphid colonies
Soft new growth attracts aphid colonies, which cause distorted shoot tips and secrete honeydew that encourages sooty mould. Knock off with a strong jet of water, introduce biological controls (Aphidius), or spray with insecticidal soap diluted per label instructions.
Root rot
Overwatering, particularly in winter, leads to Phytophthora or Pythium root rot. Symptoms are sudden wilting despite moist soil and yellowing lower leaves. Improve drainage, reduce watering frequency, and repot into fresh well-draining mix, trimming any blackened roots.
