Troubleshooting
Finger Mesemb problems — and how to fix them
Finger Mesemb (Dactylopsis digitata) 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.
Summer rot
Watering in summer dormancy rapidly causes rot. The plant must be kept dry from late spring to early autumn without exception.
Etiolation
Elongated, pale cylindrical leaves indicate insufficient light. Move to a brighter location or use a grow light.
Mealybugs
Check among the leaf bases where mealybugs can shelter. Treat with isopropyl alcohol on a cotton swab.
Cold damage
Temperatures below 5°C cause damage. Keep frost-free at all times; bring indoors well before autumn frosts.
