Growing it

Propagation: division
When to plant: spring
Overwintering: Keep the plant in a warm, bright location away from cold drafts. Reduce watering during the winter rest period to prevent root rot.
In containers: It thrives in containers, specifically slatted wooden baskets or pots with excellent drainage.

Division

1. Wait until the plant has finished blooming and new growth is starting.
2. Carefully remove the plant from its pot and gently shake off old medium.
3. Use a sterile blade to divide the rhizome, ensuring each section has at least three pseudobulbs.
4. Pot the divisions into fresh orchid bark.
5. Keep the new divisions slightly drier until new roots appear.

Group orchids together to create a microclimate that helps maintain higher ambient humidity.
