Hi everyone! Update: the kalanchoe got powdery mildew yet again. She is overall very sickly and survived a whole lot, pests, molds, ect. over the past year. Do you have any advice for starting one over from scratch? Do I cut everything down to a stump? or propagate? You think this one has a chance at a respectable afterlife? Thank you guys! I'd really appreciate any advice on this one:)
