Culture:
Light:
1800-2500 fc. Light should be filtered or diffused, and plants should not be exposed to direct midday sun. Strong air movement should be provided at all times.
Temperatures:
Summer days average 69-70F (21C), and nights average 55-57F (13-14C), with a diurnal range of 12-14F (7-8C).
Humidity:
75-80% most of the year, but averages fall to 65-70% for a few months from early spring to early summer. WATER: Rainfall is moderate to heavy in summer and autumn, but averages are somewhat lower in winter and spring, with the driest months occurring in spring. There is not a severe or extended dry season, however, and conditions in the high-elevation, rainforest habitat are probably wetter than indicated by the data from the low-elevation weather station. Cultivated plants should be watered heavily while actively growing, but drainage must be excellent, and conditions around the roots should never become stale or soggy.
Fertilizer:
1/4-1/2 recommended strength, applied weekly when plants are actively growing. Many growers prefer to use a balanced fertilizer throughout the year; but others use a high-nitrogen fertilizer from spring to midsummer and then switch to one high in phosphates in late summer and autumn.
Rest period:
Winter days average 59-60F (15-16C), and nights average 46-47F (8C), with a diurnal range of 13F (7C). Rainfall is lower in winter and spring, but there is no actual dry season. Water should be reduced for cultivated plants in winter and spring, but the should not remain completely without water for long periods. Fertilizer should be reduced when water is reduced, with both increased gradually when new growth starts.
Growing media:
Plants may be grown in shallow, well-drained containers or mounted on tree-fern slabs. Mounted plants need high humidity, however, and during hot, dry weather they may need several waterings a day. If it is difficult to keep mounted plants moist enough, they may be grown in a shallow pot or basket filled with a very open, fast-draining medium that has excellent drainage, is well aerated, and allows the medium to dry fairly rapidly after watering. Growers generally use medium-sized fir bark or shredded tree-fern fiber and add varying amounts of chunky perlite and/or chopped sphagnum moss to keep the medium open and retain some moisture. Including charcoal in the mix also holds the medium open and prevents souring in the pot. Plants should be repotted immediately if the medium starts to break down or whenever the plant outgrows its container. Repotting should be done just as new roots start to grow. This enables the plant to become reestablished in the shortest possible time.
