I only have a year of experience with Primulina spp., but they do respond well to fertilizer and watering. I'm not used to watering my plants as often as they seem to like. But they do like very porous soil. Being from a wet environments, I assume they prefer acid soil. Now that I have a metal roof, it is so much easier to collect rain water. Makes a big difference compared to the high pH city water. And especially for cactus..... who woulda thought?
