TEMPERATURES: Summer days average 75-75F (23-24C), and nights average 61-62F (16-17C), with a diurnal range of 12-14F (7-8C).

GROWING MEDIA: In the wild, plants produce a very long rhizome and often grows in thick layers of moss or deep layers of leafy humus. They are best cultivated in an open, well-drained medium that stays moist without becoming soggy. Even though these plants often grow on or near limestone, adding limestone chips to a potting mix is not recommended. Limestone dissolves rapidly in cold water and can easily cause a toxic buildup of calcium in the medium.  Cultivated plants can be somewhat difficult to manage because they produce new growths on an elongated rhizome. Growths may be as much as 6 in. (15 cm) apart. Because of its growth habit, new growths can be trapped inside the pot which damages the new growth and if rot develops, it may endanger the entire plant. Many growers use hanging baskets or broad, shallow bulb-pan type pots in which to cultivate this species. Growers feel that their plants seem healthier if repotted every year in a fresh medium.  Most growers use fine or medium grade fir bark mixed with perlite or other moisture retaining additives. Chopped sphagnum is often added to the mix, especially in drier areas with low humidity. Charcoal may be included to keep the medium open and keep it from becoming sour. Because plants grow on limestone cliffs in nature, some growers recommend adding limestone chips to the medium. Growers are cautioned that limestone dissolves rapidly in cold water, however, and this may result in a buildup of toxic levels of calcium. Growers in areas with highly mineralized water should not add limestone to the potting mix.  Plants may be repotted at any time, but it is usually done in early spring immediately after flowering. This gives the plant a chance to recover and become established before the stress of summer heat. When repotting, the junction of the roots and stem should be about one inch. (2.5 cm) below the top rim of the pot and about 1/2 in. (1.3 cm) below the top of the medium. If the medium settles so that the junction is exposed, more medium should be added to cover it.
