Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Water regularly, keeping the soil consistently moist but not waterlogged. Allow the top 2-3 cm of soil to dry out between waterings.
Reduce watering during the dormant winter months, but do not let the soil become completely dry. Ensure good drainage to prevent root rot.
Prune away any dead, damaged, or yellowing leaves to maintain a tidy appearance and promote healthy growth. Remove spent flower stalks after blooming to encourage further flower production.
Pruning can be done at any time of year as needed.
Easily propagated by division of the rhizomes. Separate healthy rhizome sections, each with at least one pseudobulb and a few roots, during repotting. Plant them in well-draining potting mix.
New plants will emerge in the spring.
Repot every 2-3 years or when the plant outgrows its container, typically in early spring before new growth begins. Use a well-draining potting mix formulated for epiphytes or orchids.
Choose a pot that is only slightly larger than the current root ball.
