Jo, They grow pretty much like orchids...In general, filtered sun, fast draining soil, balanced fert. while in growth, drier, and no fert in winter. I grow mine outside all year in zone 10, in hanging baskets with cactus mix. When they start budding in spring, I give them some bloom food, then Osmocote through summer into fall. Let them get almost dry between waterings. Watch for mealies and scale and protect from snails/slugs. They do like to be cool in winter, so a cool, bright room , or greenhouse is the way to go. That's the "nutshell" version. Happy growing!
