3. Pot each division separately in a well-draining orchid mix.
4. Water slightly and add some fertilizer.

Keiki Paste

Keiki paste is a plant hormone that promotes the formation of new buds or shoots from the nodes of orchids. Keiki paste can be applied to the aerial roots of Listrostachys pulchella Kraenzl. to encourage the formation of baby plants. Here are the steps:

1. Prepare keiki paste following the manufacturer's instructions.
2. Apply the paste onto a few of the aerial roots using a clean and sterile brush.
3. Cover the roots with a plastic wrap and secure it in place using twist ties.
4. Wait for a few weeks or until you see some buds forming from the covered roots.
5. When the baby plant is large enough, carefully remove it from the parent plant and pot it separately.

Seed Propagation

Propagation via seed is the most difficult but the most exciting way to reproduce Listrostachys pulchella Kraenzl. Seed propagation requires sterilization and special growing conditions. Here are the steps:

1. Collect the mature seeds and rinse them with a fungicide solution.
2. Spread the seeds on a sterile medium such as agar or sphagnum moss.
3. Place the medium and seeds in a sealed container to maintain high humidity but with good ventilation. Keep away from light until germination.
4. After germination, gradually introduce the seedlings to a brighter location and more air movement.
5. Pot the seedlings individually in a well-drained medium mix when they are large enough to handle.

Whichever method you choose, patience and attention to detail are necessary for propagating Listrostachys pulchella Kraenzl. Happy propagating!
