Caralluma europaea problems — and how to fix them
Caralluma europaea (Caralluma europaea) 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 rot from overwatering
Soft, blackening, collapsing stems mean the roots and base are rotting. Cut back to firm tissue, let it callus, and replant in dry gritty mix; water far less.
Mealybugs
White cottony clusters hide in the stem angles and at the soil line. Dab with 70% isopropyl alcohol and treat the roots, where root mealybugs also lurk.
Etiolation in low light
Pale, stretched, thin stems reaching for a window signal too little light. Move to direct sun; etiolated growth will not revert but new growth stays compact.
Winter cold-wet damage
Watering during cool dormancy causes translucent, mushy stem bases. Keep nearly dry and above 12C from autumn to early spring.
