Propagating orchids at home can be a rewarding experience, especially with Phalaenopsis (moth orchids). While not every orchid will produce offspring easily, Phalaenopsis sometimes forms small plantlets called keikis. Below you'll find practical advice for recognizing, separating, and potting keikis, as well as tips on cuttings and common mistakes to avoid.

What is a keiki?

A keiki is a small plantlet that grows from a node on the flower stem (spike) of a mature Phalaenopsis orchid. It develops its own leaves and roots while still attached to the mother plant. Keikis are a natural way for some orchids to reproduce, though not all Phalaenopsis will produce them spontaneously.

When and how to separate keikis

Patience is key. Only separate a keiki when it has at least 2–3 healthy roots, each about 5 cm (2 inches) long. This usually takes several months. Attempting to remove a keiki too early can damage both the keiki and the mother plant.

Step-by-step: Potting a keiki

1. Check root length: Wait until the keiki has at least 2–3 roots, each 5 cm or longer.
2. Prepare your workspace: Use clean, sharp scissors or pruning shears. Wash your hands to avoid spreading disease.
3. Remove the keiki: Gently cut the keiki from the flower stem, leaving a small section of stem attached if possible.
4. Potting: Place the keiki in a small pot with fresh, airy orchid bark. Position the roots gently and avoid burying the stem.
5. Aftercare: Mist the keiki lightly and keep it in a warm, bright spot out of direct sunlight. Avoid overwatering—let the bark dry slightly between waterings.

Common mistakes in propagation

• Separating too soon: Keikis need well-developed roots before removal.
• Overwatering: Young keikis are sensitive to rot. Let the bark dry out slightly between waterings.
• Using old or compacted bark: Always use fresh, airy orchid bark for potting keikis.
• Expecting every orchid to produce keikis: Not all Phalaenopsis will form keikis, and some hybrids rarely do.

Frequently Asked Questions

What is a keiki on an orchid?

A keiki is a baby plant that grows from a node on the flower stem of some orchids, especially Phalaenopsis. It develops its own leaves and roots while still attached to the mother plant.

How do I know when a keiki is big enough to remove?

Wait until the keiki has at least 2–3 healthy roots, each about 5 cm (2 inches) long. This ensures it can survive on its own after separation.

Can I propagate a Phalaenopsis by stem cuttings?

Phalaenopsis orchids are rarely propagated by stem cuttings. Keikis are the most reliable method for home growers. Stem cuttings usually do not root successfully in this genus.

How long does it take for a keiki to bloom?

It can take 2–3 years for a keiki to mature and produce its first flowers, depending on growing conditions and care.
