I repotted my Huernia Zebrina and Huernia Schneideriana I battled mealies on these since I got them from a nursery last year. It nearly killed them, especially the Schneideriana, most of which rotted. I managed to destroy the infestation and salvage some stems and they are finally fit enough for new pots.
