Phalaenopsis Orchid Care & Maintenance

Phalaenopsis orchids are sometimes known as "moth orchids" because the flowers resemble moths in flight. The genus Phalaenopsis contains more than 55 species of plants native to tropical Asia. The plants are characterized by arching flower spikes with blooms in shades from purest white to pinks, purples, yellows and bi-colors.
  1. Getting Started

    • Most orchids are purchased in bud or in bloom, growing in a special bark-like medium. Place the orchid in a window where it will receive bright, indirect light. While the plant cannot be placed in standing water, setting it in a pebble tray with water in the bottom ensures desirable humidity levels.

    Temperature

    • Phalaenopsis thrives when temperatures are about 65 degrees Fahrenheit at night and 10 degrees warmer during the day. Lower temperatures (50 to 60 degrees F) in September and October help stimulate flowering.

    Food and Water

    • Water only when the potting medium is dry. Stand the pot in water for 10 to 15 minutes, then remove it, letting any excess drain away. Feed the orchid once a month, using fertilizer specifically designed for orchids or a balanced 15-15-15 fertilizer.
