Troubleshooting
Cocoon Plant problems — and how to fix them
Cocoon Plant (Senecio haworthii) 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.
Fungal rot of woolly leaves
White hairs trap moisture and harbour fungal spores in humid conditions. Improve air circulation, reduce watering, and never wet the foliage. Remove any affected leaves promptly and treat with a fungicide if spreading.
Stretching and loss of compact form
Caused by low light levels. Stems elongate and gaps appear between leaves. Move to the brightest available window or supplement with a grow light placed 20–30 cm above the plant.
Root rot
Overwatering in combination with slow-draining soil is the primary killer. Symptoms include yellowing, mushy stems at the base, and leaf drop. Unpot, trim rotten roots, dust with sulfur, and repot into fresh, dry gritty mix.
Prevent cocoon plant problems before they start
Most cocoon plant issues are care-mismatch, not bad luck. Dial in the basics:
