In the Summer provide intermediate temperatures, plentiful water, good air circulation and very dilute fertiliser occasionally. Mist several times a day if mounted on cork bark. Light levels should be bright but no direct sun or foliage will burn.
In the Winter, give the plant a drier (not dry) rest in brighter light but only early morning direct sun. Temperatures can drop to near freezing without damaging the plant, providing it is kept very dry. It must have dried out before temperatures drop in the afternoon.
If grown intermediate, regular misting is still needed if it is mounted, but needs to be only every couple of days - or less -depending on the prevailing weather. Good air circulation is needed.
Water sparingly if potted.
