Troubleshooting
Nananthus transvaalensis problems — and how to fix them
Nananthus transvaalensis (Nananthus transvaalensis) 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 rot from overwatering
The swollen taproot is the plant's most vulnerable part; wet, cold, or compacted soil rots it quickly. Keep the mix gritty and water only when fully dry, almost never in dormancy.
Etiolation
Low light causes the leaves to stretch and the rosette to loosen. Provide the brightest possible position to maintain the dense, characterful shape.
Shrivelled leaves
Pronounced shrivelling in growing season can mean underwatering or a dehydrated root; a deep soak once dry usually restores turgor. Some shrivelling in dormancy is normal.
Mealybugs and root mealybugs
Both foliage and root mealybugs target tuberous mesembs. Check the crown and roots at repotting; treat with isopropyl alcohol or a systemic insecticide.
