How to care for a moth orchid

The most common orchid sold as a houseplant. It likes low light, warmth and humidity, and does best on an east windowsill. Grow it in a bark-based orchid mix, not plain potting soil. Water in the morning with lukewarm water: run it through the pot in the sink, let it drain completely, and let the mix dry somewhat before the next watering, about weekly. Feed twice a month at half strength. After the flowers fade, cut the stalk just above the first node below them; it often branches and blooms again. Repot about every two years. Large white spring-blooming types need about a week of 55°F nights in autumn to set flower spikes.

Common problems

Pure sphagnum moss is hard to rewet; repot into bark mix. Never let the pot sit in water.
