I have 3 clivia plants and have also given away at least 6 cuttings. My plants acquired a fungus or powdery mildew from an orchid plant I was advised to use insecticidal soap, which seemed to get rid of the powdery mildew. But none of them has bloomed for the past 2 or 3 years since being infected. Any suggestions?
