Culture:
Light:
1200-1800 fc. Plants require shady conditions and initiate flower spikes even in extremely low light. They should be protected from high light. Strong air movement should be provided at all times.
Temperatures:
Summer days average 82–84F (28–29C), and nights average 64–65F (18C), with a diurnal range of 17–20F (9–11C). These temperatures are the average conditions under which this species grows.
Humidity:
75–80% most of the year, dropping to 65–70% for about 4 months in late winter and spring.
Water:
Rainfall is moderate to very heavy from late spring to autumn. Average rainfall then drops rapidly into a five–month dry season that starts in late autumn and lasts until early spring. Cultivated plants should be watered heavily while actively growing, but their roots must dry rapidly after watering.
Fertilizer:
1/4–1/2 recommended strength, applied weekly. A high-nitrogen fertilizer is beneficial from spring to midsummer, but a fertilizer high in phosphates should be used in late summer and autumn.
Rest period:
Winter days average 72–74F (22–23C), and nights average 52–54F (11–12C), with a diurnal range of 19–22F (11–12C). Rainfall in the habitat is low from autumn to early spring and in the northern parts of the island the dry season lasts even longer. Humidity is high throughout the year, however, so considerable moisture is available from heavy dew and late-night mist. Cultivated plants need less water in late autumn through winter, but they should be watered periodically to prevent excessive drying. Occasional early-morning mistings between infrequent light waterings should provide sufficient moisture in most growing areas. Water should be increased somewhat if leaves shrivel or show signs of stress. Fertilizer should be eliminated until new growth starts and heavier watering is resumed in spring.
Growing media:
Plants seem to grow better when mounted on slabs of cork with a pad of sphagnum under the base of the plant. Hillerman & Holst (1986) reported that plants must dry out between mistings, however, and suggested mounted plants be misted or drenched 4-6 times per week. If pots must be used, a very open medium that allows good air movement around the roots should be used, and the plant must dry out between waterings. Baskets or undersized clay pots probably produce better results than do plastic pots. Repotting should be done just as new root growth is starting in order for the plant to become established in the shortest possible time.
