What is Moth Orchid?

Fact reviewed by Eleanor Hayes

Moth orchids are mainly epiphytic orchids with broad leathery leaves, thick aerial roots, and long-lasting flowers carried on arching spikes. Most plants sold for rooms are unnamed hybrids rather than a single species.

Look for a short central stem, a small stack of broad strap-like leaves, and thick roots that turn silvery as they dry. Flowers have a distinct central lip and are held along an arching spike.

Light

Provide bright filtered light and protect the leaves from direct midday or summer sun. An east- or west-facing windowsill is often suitable when the plant is shielded from hot glass.

Watering

Water when the bark is nearly dry and exposed roots have turned pale or silvery, then drain completely. Keep water out of the crown between the leaves to reduce the risk of bacterial rot.

Soil

Grow moth orchids in an open bark-based orchid mix, not ordinary potting soil. Air around the roots is essential, and a clear slotted nursery pot makes root moisture easier to judge.

Fertilizer

Use an orchid fertilizer at a weak concentration while Moth Orchid is actively growing. Flush the medium with plain water between feedings and reduce fertilizer during rest.

Propagation

Home propagation is usually limited to removing a naturally produced keiki after it has several roots at least about 2 cm long. Seed propagation requires sterile laboratory conditions and is not a practical beginner method.

Pruning

Remove dead Moth Orchid roots or flower spikes only with sterile tools and after confirming the tissue is no longer active. Spike-cutting rules vary by orchid genus.

Temperature

Keep Moth Orchid near 17°C - 25°C and protect it from abrupt drafts, heater blasts, and hot window glass.

Growing in a container

Moth Orchid should be repotted when roots are crowded, drainage has slowed, or the mix has broken down—not simply because a larger pot looks attractive. Increase the container only modestly and preserve the original planting depth.

Common problems

  • Wrinkled leaves or roots: Check whether roots are dry and silvery or brown and rotten before deciding to water more.
  • Black crown tissue: Keep water out of the leaf crown and remove standing water promptly.
  • No repeat bloom: Provide bright filtered light and a modest difference between day and night temperature.
