What To Know
- Fill in the remaining space with more potting mix, pressing it firmly around the base of the keiki.
- You can increase humidity by misting the keiki or placing it on a tray filled with pebbles and water.
- The time it takes for a keiki to bloom varies depending on the species and growing conditions.
Keikis, the adorable plantlets that emerge from orchid stems, are a testament to the vitality of these captivating plants. Repotting keikis is a crucial step in their development, ensuring they have the necessary resources to thrive and bloom. This comprehensive guide will empower you with the knowledge and techniques to successfully repot your orchid keikis and nurture their growth.
Understanding Keikis
Keikis are small, vegetative plantlets that develop on orchid stems or flower spikes. They are essentially miniature versions of the parent plant, complete with their own roots, stems, and leaves. Keikis are a natural means of asexual reproduction for orchids, allowing them to propagate without the need for pollination.
Signs Your Keiki Is Ready for Repotting
As your keiki grows, it will gradually develop its own root system. Once the roots are well-established and at least 2-3 inches long, it’s time to consider repotting. Other indicators of keiki readiness include:
- Visible root tips: The tips of the roots should be white and actively growing.
- Firm stem: The keiki’s stem should be firm and upright, supporting the plantlet’s weight.
- Healthy leaves: The leaves should be green and free of any pests or diseases.
Materials You’ll Need
Before embarking on the repotting process, gather the following materials:
- Sharp, sterile knife or pruning shears
- New orchid pot with drainage holes
- Orchid potting mix (specifically formulated for epiphytic plants)
- Sphagnum moss or bark (optional)
- Water
- Fungicide (optional)
Step-by-Step Repotting Instructions
1. Prepare the New Pot:
Fill the new orchid pot with a layer of orchid potting mix. Gently press down to firm it.
2. Sever the Keiki:
Using a sharp knife or pruning shears, carefully cut the keiki from the parent plant. Make a clean cut close to the base of the keiki. Dip the cut end in fungicide if desired.
3. Prepare the Keiki:
Remove any dead or damaged roots from the keiki. If the roots are tangled, gently loosen them using your fingers.
4. Plant the Keiki:
Place the keiki in the center of the prepared pot. Spread the roots out evenly and gently press them into the potting mix. Fill in the remaining space with more potting mix, pressing it firmly around the base of the keiki.
5. Top with Moss or Bark (Optional):
For added stability and moisture retention, you can top the potting mix with a layer of sphagnum moss or bark.
6. Water:
Water the keiki thoroughly, allowing the excess water to drain from the pot.
7. Provide Support:
If necessary, provide support for the keiki using a stake or wire. This will help the plantlet stand upright and prevent it from toppling over.
Post-Repotting Care
- Light: Place the repotted keiki in a bright, indirect location. Avoid exposing it to direct sunlight, which can scorch the leaves.
- Water: Water the keiki when the potting mix feels slightly dry to the touch. Allow the excess water to drain from the pot.
- Fertilizer: Fertilize the keiki monthly with a balanced orchid fertilizer.
- Humidity: Orchids thrive in humid environments. You can increase humidity by misting the keiki or placing it on a tray filled with pebbles and water.
Monitoring and Troubleshooting
Monitor the keiki regularly for signs of growth and health. If you notice any yellowing leaves, stunted growth, or pests, take appropriate action.
Wrapping Up
Repotting orchid keikis is a rewarding experience that allows you to nurture new plantlets and expand your orchid collection. By following these detailed instructions, you can ensure your keikis thrive and bring you years of blooming beauty.
FAQ
1. How often should I repot my orchid keiki?
Repot your keiki once it has developed well-established roots (at least 2-3 inches long).
2. Can I repot multiple keikis together?
Yes, but make sure the pot is large enough to accommodate all the keikis without overcrowding.
3. What type of potting mix should I use for my keiki?
Use a potting mix specifically formulated for epiphytic plants, such as orchids.
4. Do I need to use fungicide when repotting my keiki?
Using fungicide is optional, but it can help prevent fungal infections.
5. How long does it take for a keiki to bloom?
The time it takes for a keiki to bloom varies depending on the species and growing conditions. Generally, it can take several years.
