BigBill said:I heard a talk on these types of plants by Leon Glichtenstein last June and just as Ursula has suggested, a fluffy mix featuring peat is highly recommended. When they go dormant, he dries them completely and puts them in very dim light and with holds water.
He moves them gradually to brighter light and provides them with a little water come late winter. I believe he said late winter to spring. Time and months would vary due to your geographic location. But then these guys start to awaken. He reports very infrequently.
