Primrose Huernia problems — and how to fix them
Primrose Huernia (Huernia primulina) 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
The most common issue, caused by overwatering or poorly draining soil. Stems turn brown and mushy at the base. Remove affected sections, allow cuts to callus, and repot into fresh dry mix.
Failure to flower
Insufficient light or skipping the winter dry rest prevents blooming. Ensure the plant receives bright light year-round and reduce watering significantly from October to February to trigger bud set.
Mealybugs
White, cottony clusters appear between stem ribs. Dab with isopropyl alcohol on a cotton swab or spray with neem oil solution. Inspect new plants carefully before introducing to a collection.
