How to care for Moth Orchid
Phalaenopsis amabilis · Orchidaceae
The moth orchid is the world's most popular houseplant orchid for good reason: its arching sprays of blooms last for months, and it thrives at ordinary room temperatures. It grows in bark rather than soil, with thick silvery roots that photosynthesize. Once you unlearn soil-plant habits, it is genuinely easy. Water roughly every 7 days while it's growing (about every 10 in winter), give it bright, indirect light, kept above 61°F (16°C) — average room humidity suits it.
Care at a glance
Water when the roots turn silvery and the bark is dry — soak the pot thoroughly, drain completely, and never leave water in the crown or cachepot.
An east window is classic; leaves should be olive green — very dark green means too little light, red-tinged means too much.
Quarter-strength orchid fertilizer every other watering — 'weakly, weekly' beats occasional strong doses.
Mistakes that kill this plant
- Leaving it standing in water inside a decorative pot with no drainage.
- Watering into the crown and letting water sit there, causing crown rot.
- Never repotting, so the bark decomposes into a root-smothering mush.
Seasonal tips
- A few weeks of cooler autumn nights (around 61–64°F (16–18°C)) triggers a new bloom spike.
- After flowering, cut the spent spike above a node for a possible rebloom, or at the base to let the plant rest.
- Repot into fresh bark every couple of years — old, broken-down bark suffocates roots even with perfect watering.
