Moth Orchid
Phalaenopsis
Moth Orchids are known for long-lasting blooms that look a bit like moth wings. Native to Southeast Asia, these epiphytes grow on trees in the wild and draw moisture from air and rain. They are among the easiest orchids for typical homes and can flower for months.

Care Notes
Light
Place in bright, filtered light such as an east window. Direct midday sun burns the thick leaves.
Water
Water about once a week when the bark mix feels nearly dry. Use lukewarm water and keep it out of the crown between the leaves, where rot starts. Morning watering is best.
Soil
Grow in orchid bark, sphagnum, or a bark mix with perlite and charcoal. Clear pots with drainage holes make it easier to check root health. Repot every 1 to 2 years when the medium breaks down.
Humidity and Temperature
Keep temperatures between 65°F and 85°F. A slight night drop in fall can help trigger blooms. Aim for humidity around 50% to 70% with a pebble tray or humidifier. After flowers fade, cut the spike to the base to rest the plant, or cut above a node for a possible second flush.
Common Issues
Yellow, mushy roots mean overwatering. Wrinkled leaves often mean underwatering or a depleted mix. Spotted leaves can follow sunburn or water left in the crown.
