Phalaenopsis
BeginnerPhalaenopsis spp.
Japan's most beloved gift orchid with butterfly-like blooms lasting weeks. Epiphytic, typically grown in sphagnum moss. Proper care allows re-blooming multiple times a year.
About
Phalaenopsis, commonly known as moth orchids, is a genus of approximately 70 species in the family Orchidaceae, native to tropical and subtropical Asia—particularly the Philippines and Indonesia—as well as New Guinea and northern Australia. These monopodial epiphytes grow on tree trunks and rocky surfaces in humid rainforests, producing long, coarse aerial roots adapted to absorb moisture from the atmosphere. The flat, symmetrical flowers, arranged on arching or branching inflorescences, bear ten or more blooms that persist for several months. Flower colors span pure white, pink, purple, yellow, and intricate multicolored patterns. Watering is best timed when aerial roots turn silvery-white. The combination of long-lasting blooms, diverse coloration, and adaptability to indoor environments has made Phalaenopsis the world's most commercially successful potted orchid.

Growing Tips
Light & Placement
From spring to autumn, keep it in a bright indoor spot behind a sheer curtain. Direct sun scorches the leaves, so avoid it.
Watering
Water once the sphagnum moss has dried. Silver-white roots signal watering time; avoiding overwatering is the key to long-term success.
Temperature & Overwintering
Grow it at 18-30°C (ideally 20-25°C) and keep it above 15°C in winter. Keep it away from cold drafts by windows.
Soil & Repotting
Pot in sphagnum moss or bark. Aim for 50-70% humidity, and replace the medium once it breaks down.
Fertilizer
From spring to autumn, give diluted liquid fertilizer twice a month. Growth slows in winter, so hold off on feeding and water only after the medium dries.
Pruning & Shaping
After flowering, cutting the spike back above a node may produce a side branch that blooms again. If the plant is weak, cut the spike at the base instead.
