LYCASTE

The genus Lycaste produces large, waxy flowers that are long lasting and in many species, fragrant. Lycaste are noted for their roundish bulbs and broad pleated (plicate) leaves. There are two generally recognized cultural groups—the deciduous aromatica type that flowers from leafless pseudobulbs and the evergreen skinnerii type that flowers from leafy pseudo bulbs.

LIGHT Requirements vary depending on the species and growth phase. Deciduous species prefer light conditions similar to Cattleyas from 2,000 to 4,000 foot candles. Provide the higher end light when the new growths are forming. The evergreen species prefer less light overall, from 1,500 to 2,000 foot candles.

TEMPERATURES The deciduous species of Lycaste are tolerant of a wide range of temperatures from 50 degree nights to 95 degree days. The evergreen species have a narrower range from 52 to 58 degree nights to 65
to 75 degree days. They should not be allowed to reach over 75 degrees.

WATER should be applied in copious amounts during active growth, when the plants are producing new leaves and growths. Let the potting media begin to dry out before watering. Evergreen species should be kept only slightly drier when not in growth mode. The deciduous species should be kept nearly completely dry when leafless.

FERTILIZER should be used every time you water your Lycastes. Use a balanced fertilizer (20-20-20) at ½ strength in the summer growth phase. Use the same fertilizer at ¼ strength during the winter, non growth phase. Regular monthly to every 6 weeks plain water flushings will prevent salt build-ups.

HUMIDITY Lycastes love humidity. It should be maintained at 50 to 70%. Good air movement will prevent leaf spotting. The deciduous varieties should have the lower end of the humidity range when leafless. In a home growing environment, use of humidity trays partially filled with gravel and water is beneficial.

REPOTTING As with nearly all orchids, Lycastes should be repotted when new growth starts. We’ve had success with both a bark mix (fine bark, some medium bark, perlite and charcoal) and a New Zealand sphagnum moss/ perlite combination. If you divide your Lycaste, make sure each division has at least three bulbs. Pot with the back bulbs snuggled next to the rim of the pot to allow the new growths plenty of room. Provide high humidity and less water to encourage new roots to form.
