Moth Orchid (Phalaenopsis) Care Guide

The moth orchid is the one you see everywhere, from supermarkets to hotel lobbies, and there is a reason for that: it is by far the easiest orchid to grow. Its elegant arching stems carry flowers that last for weeks, sometimes months, in shades of white, pink, purple, yellow and spotted patterns. Once you understand its few quirks, it is surprisingly low-maintenance.

Good to know

Orchids are not parasites. In the wild, phalaenopsis grows on tree branches, using the bark for support and pulling moisture from the humid air. That is why it is potted in bark chips rather than soil. Those silvery-green aerial roots growing out of the pot are completely normal and healthy, do not cut them off or bury them.

Light

Bright, indirect light. An east-facing window with gentle morning sun is ideal. Avoid direct afternoon sun, which burns the leaves, and avoid deep shade, where it will not flower. If the leaves are a healthy medium green, the light is right. Dark green leaves mean too little light.

Water & humidity

Water every seven to ten days by soaking the pot in room-temperature water for 10 to 15 minutes, then letting it drain completely. Never let water pool in the crown of the plant, which causes rot. The roots should go from silvery-grey (dry) to green (wet) when watered, which is a handy visual guide. Reduce watering in winter. Normal to slightly raised humidity is fine.

Feeding

Feed every two weeks through the growing season with a specialised orchid fertiliser at half strength. Reduce to monthly in winter.

Repotting & soil

Repot every one to two years, or when the bark has broken down and become soggy. Use orchid bark, not potting soil. A clear plastic pot is ideal because it lets you see the root condition and allows light to reach the roots.
