Species and hybrid Lycaste Orchids are becoming very popular for their large numbers of large long lasting flowers offering a wide range of colors. “Lycastes” have their ancestry in the high cloud forests of above 85%F during the day, throughout the year. the more closely these conditions can be duplicated in home, the yard, or the greenhouse, the better the plant will grow and bloom.
Filtered, indirect light ranging from 1000 to 1500 foot-candles is appropriate for Lycaste. Direct sun will burn the leaves, and too little will result in few if any flowers. The leaves should be bright green. Yellowish green leaves indicate too much light while dark green leaves indicate not enough light.
Temperature & Humidity
Minimum night temperatures of 55%F and maximum daytime temperatures of 85%F are ideal, though the plants will tolerate slightly higher or lower temperatures for short periods of time. Extra shading will help keep the temperatures down in warm area.
The ideal humidity is between 50 to 75%, with as much ventilations on air movement as possible. Growing plants on gravel trays or misting on bright days will also help keep humidity up, as will grouping several plants together.
Watering & Fertilizing
Plants grown in a mixture of fir bark and perlite or sphagnum moss need to be kept moist, not soggy, or the roots will be killed very quickly. Mature
plants should approach dryness particularly from blooming time until the new growth appears; seedlings should be kept evenly moist.
Feed with a balance fertilizer (20-20-20) at 1/2 strength every other watering.
Repotting is done after bloom when the plant’s new growth is 3-6″
tall, in the early spring through the early summer, but never during the hot summer months. Clean off the old potting mix. If dividing plants, keep the divisions in clumps of three to five mature bulbs. Plants grown in sphagnum moss should be potted in net pots or well drained plastic pots. Select a pot size that will just accommodate the roots, do not over-pot
