Good drainage. Protect or move indoors during freezes and multi-day rains. Happy gardening in your new home!

Well, I was talking through my hat as I did not look up kalenchoe rhombopilosa and assumed it was what I know as a kalenchoe (green leaves, bears colored flowers) - blossfeldiana, I guess. Your new little plant is not a cactus, though it may get shelved with cacti and succulents at retailers, so my advice on avoiding constant rain may not hold water (sorry, can't help myself). Not living in freeze-land, however, I don't know how they will fare for you in Orlando. Check with your neighbors, perhaps (good way to make gardening friends).

Thank you!!
