Light:
1200-2000 fc. Plants require shady conditions and should be protected from bright light. Strong air movement should be provided at all times.
Temperatures:
Summer days average 82-83F (28C), and nights average 70-71F (21-22C), with a diurnal range of 12F (7C).
Humidity:
Near 85% most of the year, dropping to near 80% for 2-3 months in spring.
Water:
Rainfall is very heavy most of the year. Amounts decrease somewhat for a month or so in spring, but the habitat is never truly dry. Cultivated plants should be watered heavily while actively growing, but 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 use a balanced fertilizer throughout the year, but others prefer to use a high-nitrogen fertilizer from spring to midsummer, switching to a high-phosphate formula in late summer and autumn.
Rest period:
Winter days average 72-74F (22-23C), and nights average 61-63F (16-17C), with a diurnal range of 10-12F (6-7C). Although rainfall in the region remains heavy all year, plants grown in the dark, short-day conditions common in temperate latitude winters need less water. They should never dry out completely, however. Fertilizer should be reduced if water is reduced.
Growing media:
Hawkes (1965) suggested that "These orchids are best grown in rather shallow, perfectly-drained pots or pans, filled with a porous compost of shredded osmunda, fibrous loam, gritty sand, and chopped sphagnum moss." He stated, "Most of the Cynorkis have somewhat tuberous roots, and are at least partially deciduous. Although they require quantities of water while in active growth, when the foliage starts to become yellow and wither, moisture should be virtually stopped. Care must be taken, however, that the compost never dries our completely, or the tubers may become overly desiccated. When the new shoots again appear at the surface, water should be resumed." Plants should be repotted immediately if the medium becomes stale or remains soggy after watering as these plants are very intolerant of sour conditions at the roots. With this in mind, it is probably advisable to repot every year while the plant is dormant, particularly if chopped sphagnum moss is included in the potting mix.
