Huernia macrocarpa problems — and how to fix them
Huernia macrocarpa (Huernia macrocarpa) 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.
Stem and root rot
Overwatering or dense soil leads to soft, blackening stems. Excise affected tissue, let it callus, and re-root healthy segments in dry gritty mix.
Etiolation
Insufficient light produces pale, stretched, weak stems and poor flowering. Move to a brighter spot with some gentle direct sun.
Mealybugs
These pests hide between stems and at the base. Wipe with 70% isopropyl alcohol or treat with insecticidal soap and isolate the plant until clear.
Failure to flower
Usually too little light, over-feeding with nitrogen, or no dry winter rest. Give a bright spot, a cool dry winter, and lean feeding to trigger buds.
