Troubleshooting
Canary Island Monanthes problems — and how to fix them
Canary Island Monanthes (Monanthes subcrassicaulis) 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 and stem rot
Overwatering quickly causes fatal rot at the stem base. Ensure soil is bone dry before watering and that pots drain freely. Terracotta pots help prevent moisture buildup.
Etiolation in winter
The plant stretches toward low winter light. Rotate the pot regularly and supplement with artificial lighting to maintain compact rosette form through shorter days.
Mealybugs
White waxy pests shelter in leaf axils. Remove manually with alcohol-soaked cotton swabs and follow up with diluted neem oil. Inspect new plants before introducing to a collection.
