Orchid Care 101: Why Everyone Kills Them and How to Not

Phalaeonopsis orchids fail for three predictable reasons. Learn the ice-cube myth, correct potting medium, and the rebloom trigger that actually works.

The grocery-store orchid is treated like a bouquet: beautiful for six weeks, then discarded. It doesn't have to be. Phalaenopsis are long-lived plants that will rebloom yearly once you stop caring for them like a houseplant.

They are not soil plants

In the wild, phalaenopsis grow on tree bark with roots exposed to air. Potting soil suffocates them. They belong in coarse bark or sphagnum in a pot with generous drainage — ideally a clear one, so you can see root color.

Reading the roots

  • Silvery green — thirsty, time to water.
  • Bright green — well hydrated, leave it alone.
  • Brown and mushy — rot, trim it out now.
  • Wandering into the air — completely normal, don't bury them.

Triggering a rebloom

After the last flower drops, cut the spike back above a lower node and give the plant a stretch of cooler nights — around ten degrees below daytime temperature for a few weeks. That temperature drop is the signal a new spike needs.

An orchid that won't rebloom is almost always an orchid that never got a cool night.

Frequently asked

Should I water my orchid with ice cubes?
No. Ice water shocks tropical roots. Run tepid water through the bark medium at the sink once a week and let it drain fully instead.
How do I get my orchid to rebloom?
Trim the spent spike above a lower node and give the plant several weeks of cooler nighttime temperatures, roughly ten degrees below daytime, to trigger a new flower spike.
