Propagating Phalaenopsis orchids from keikis is a rewarding process that allows you to grow new plants from your existing orchids. Keikis are small plantlets that develop on the flower spike or at the base of the mother plant. With proper care and patience, these tiny orchids can become mature, flowering plants.
Understanding Keikis
Keikis, a Hawaiian word meaning “baby” or “child,” are natural or induced offsets that form on orchid stems. They typically appear on the flower spike or at the base of the plant after flowering. Keikis have roots and leaves, making them capable of independent growth once established.
Identifying a Keiki
A keiki usually has a few small leaves and visible roots. It can be distinguished from a normal flower spike by its appearance and growth pattern. Keikis often develop after the plant has finished blooming and are a sign of a healthy orchid.
Preparing to Propagate
- Choose a healthy mother plant with a keiki that has at least 2-3 leaves and well-developed roots.
- Gather clean, sharp scissors or pruning shears sterilized with alcohol.
- Prepare a suitable pot with well-draining orchid mix, such as bark or sphagnum moss.
- Have a rooting hormone available (optional) to encourage root development.
Removing the Keiki
Gently remove the keiki from the mother plant using sterilized tools. Cut the keiki with a small portion of the flower spike or stem attached, ensuring it has roots and leaves. Be careful not to damage the roots or leaves during this process.
Planting the Keiki
Place the keiki into the prepared pot, positioning the roots carefully in the orchid mix. Lightly press the medium around the roots to secure the plant. If desired, dip the roots in rooting hormone before planting to promote faster root growth.
Caring for the Keiki
Keep the newly potted keiki in a warm, bright location with indirect sunlight. Maintain humidity around 50-70% and avoid overwatering. Water only when the top of the medium feels dry. Mist the plant occasionally to increase humidity if needed.
Monitoring Growth and Development
Over the next several months, the keiki should develop new roots and leaves. Be patient, as orchids grow slowly. Once the keiki has established a strong root system and new leaves, it can be gradually acclimated to normal growing conditions.
Transplanting Mature Keikis
When the keiki reaches a size comparable to the mother plant, with several roots and leaves, it can be transplanted into a larger pot. Continue caring for it as you would an adult orchid, ensuring proper watering, light, and humidity.
Tips for Success
- Always use sterilized tools to prevent infection.
- Be gentle when handling the keiki to avoid damaging roots or leaves.
- Maintain consistent watering and humidity levels.
- Provide bright, indirect light for optimal growth.
- Be patient; orchid propagation takes time.
With care and patience, propagating Phalaenopsis orchids from keikis can be a fulfilling way to expand your collection and enjoy the beauty of these elegant plants.
