Hi Everyone, All the suggestions I've received on here have worked, so thanks to everyone who's responded in the past. Anyway, I'm taking care of my parents Christmas Cactus, complete with fungus gnats and related fungus. Here are a few questions: 1) what is the best fungicide for a succulent? 2) Will this fungicide (or the hopeful lack of fungus) eventually kill off the fungus gnats? 3) How far away from other houseplants should I keep the infected Christmas Cactus. (I've been fortunate to avoid fungus gnat problems and would love to keep it that way).
