Culture:
Light:
200-2000 fc. Plants need moderate shade and protection from direct sun. Strong air movement should be provided at all times.
Temperatures:
Summer days average 79-80F (26-27C), and nights average 62F (17C), with a diurnal range of 17-18F (10C).
Humidity:
80-85% most of the year, dropping to near 75% for about 2 months in late winter and early spring.
Water:
Rainfall in the habitat is heavy most of the year, with 2-3 rather dry months in winter. Cultivated plants should be watered heavily while actively growing. Water should be reduced somewhat in late autumn.
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, then switch to one high in phosphates in late summer and autumn.
Rest period:
Winter days average 75-77F (24-25C), and nights average 58-60F (14-16C), with a diurnal range of 17-19F (10C). Rainfall in the region is lower in winter, but it may not be quite as low in the higher-elevation habitat as indicated by the averages at the low-elevation weather station. Also, moisture from heavy dew and late-night mist is often available to the plants but is not part of the rainfall averages. Cultivated plants need less in winter, but they should never get completely dry. Fertilizer should be reduced or eliminated when water is reduced.
Growing media:
To accommodate their lengthy stems, these plants are probably most easily managed if grown in fairly large, shallow, well-drained containers to which long stakes or long moss-covered poles, branches, or tree-fern poles have been attached. The stems can then be tied to these stakes until they are attached by their own growing roots. Plants need high humidity, and during hot, dry weather they may need several waterings a day. The container should be 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 to coarse fir bark or shredded tree-fern fiber or cork nuggets 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. Repotting should be done just as new roots start to grow. This enables the plant to become reestablished in the shortest possible time.
Miscellaneous notes:
Long blooming and frequent blooming orchid species.
