Phalaenopsis orchids are among the most popular houseplants, admired for their stunning, long-lasting flowers. A common question among orchid enthusiasts is how to propagate these plants using keikis, which are small plantlets that develop on the mother plant. Understanding how to properly harvest and care for keikis is essential for successful propagation and healthy plant growth.
What is a Keiki?
A keiki is a Hawaiian term meaning “baby” or “child.” In the context of orchids, it refers to a small plant that naturally forms on the flower spike or at the base of the mother plant. Keikis contain roots and leaves, and with proper care, they can be separated and grown into independent plants.
Identifying a Keiki on Your Orchid
Keikis typically appear as small, new plantlets with roots and leaves. They often develop along the flower spike, usually near the base of a flower or at the node. Sometimes, keikis can also form at the base of the plant, especially if the orchid is healthy and well-cared for.
When to Harvest a Keiki
Wait until the keiki has developed a healthy root system, ideally at least 2-3 inches long. The leaves should be well-formed and green, indicating the plantlet is strong enough to survive on its own. Harvesting too early can jeopardize the keiki’s chances of successful growth.
How to Carefully Remove a Keiki
Use sterilized scissors or pruning shears to gently cut the keiki from the mother plant. Cut as close to the base of the keiki as possible without damaging the roots. Handle the plantlet carefully to avoid breaking delicate roots or leaves.
Planting and Caring for Your Keiki
Choose a small pot with drainage holes and use a well-draining orchid mix. Plant the keiki so that the roots are covered but the leaves remain above the soil. Keep the environment humid and maintain bright, indirect light. Water sparingly, allowing the medium to dry slightly between waterings.
Additional Care Tips
- Maintain consistent temperature between 65-75°F (18-24°C).
- Use a diluted orchid fertilizer every 2-4 weeks.
- Ensure good air circulation around the plant.
- Avoid direct sunlight, which can scorch the leaves.
Patience and Growth
Growing a healthy Phalaenopsis orchid from a keiki requires patience. It may take several months for the keiki to develop a mature root system and start blooming. Consistent care and proper environment are key to successful propagation.
Conclusion
Harvesting and growing keikis is a rewarding way to propagate your Phalaenopsis orchids. By waiting for the right development stage, handling the plantlet carefully, and providing optimal care, you can enjoy new orchids thriving in your home or classroom. Happy gardening!
