Phalaenopsis — the moth orchid — is the orchid you see in every supermarket, and it's genuinely easy if you follow its rules. The catch: those rules are different from regular houseplants. Get four things right and it will bloom for months, then rebloom for years.

1. It Grows in Bark, Not Soil

Orchids are epiphytes: in nature they grow on trees, roots exposed to air. They must be potted in coarse orchid bark, not potting soil. Never repot a phalaenopsis into regular soil — it will suffocate and rot. Repot every 2-3 years when the bark breaks down.

2. Water by Soaking, on a Schedule

Water roughly every 7-10 days: place the pot in a sink of room-temperature water for 10-15 minutes so the bark soaks, then let it drain completely. Read the roots: silvery-gray roots need water; plump green roots are fine. If in doubt, wait — overwatering is the top orchid killer.

3. Bright, Indirect Light — Not a Dark Corner

Moth orchids want bright, indirect light — an east window or a shaded south window is ideal. Pale, floppy leaves mean too little light; red-tinted or scorched leaves mean too much direct sun. Never let direct afternoon sun hit the leaves.

4. Cool Nights Trigger Reblooming

After the flowers drop, cut the spike just above a node (the little bumps on the stem) and keep caring for the plant. To trigger a new spike, give it cooler nights — around 55-65°F (13-18°C) for 2-4 weeks in autumn. That temperature drop tells the orchid it's time to bloom. New spikes appear, then buds form over several weeks.

Common Mistakes

  • Ice cubes: orchids are tropical; cold water stresses the roots. Use room-temperature soaks instead.
  • Overwatering: bark should be nearly dry between waterings. Roots need air.
  • Potting in soil: covered above — bark only.
  • Cutting healthy green roots: only remove dry, mushy, or papery roots.
  • Moving it while blooming: buds drop from sudden changes. Pick a spot and keep it.
