Troubleshooting
Dwarf Frailea problems — and how to fix them
Dwarf Frailea (Frailea pumila) 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.
Overwatering rot
The greatest threat. The tiny body stores little moisture and is very prone to basal rot if the substrate stays damp. Always err on the side of underwatering.
Mealybugs
Difficult to spot on such a small plant. Inspect areoles with a magnifier; treat with alcohol-tipped cotton bud.
Etiolation
Insufficient light stretches the body upward. Correct by gradually increasing light intensity over several weeks.
Failure to flower outdoors
Summer flowering is triggered by warmth; move to a sheltered outdoor spot in late spring if weather permits to encourage bud set.
