All of my encyclia orchids are greenhouse grown. I have found that since they do have p-bulbs, they like to dry out between being watered. Late Spring, early Summer is their bloom/growth period.They all get very bright light, and heat ( sometimes it gets to 95 degrees for short periods ) in the greenhouse.Hope this helps...Oh! almost forgot! In early Spring, I start giving all encyclias blossom booster fertilizer...BettyE
