Oeoniella polystachys

Oeoniella polystachys, a hardy plant from Madagascar. This species is common here because of tissue culture, the price is cheap. It likes warm weather, medium light, and could tolerate its condition with alterant air humidity (but it still prefer high air humidity if possible). Water it after the pot materials dry already. I grow it two years, and it always blooms on time without enough fertilizer. I place it in a flowerpot with some barks and wood coal, and because of high temperature in summer time, I water twice a day. In the winter, it's still warm here, so once watering everyday, and if cold current comes, I would stop water it in first day, and do it when at noonday in second day.
