Watering, pruning, propagation, and repotting details from plant data
Water thoroughly when the potting medium is nearly dry, typically every 7-10 days during active growth. Reduce watering significantly in winter, allowing the pseudobulbs to shrivel slightly.
Avoid overwatering, which can lead to root rot. Ensure good drainage.
Prune away any dead, dried, or diseased pseudobulbs and leaves to maintain plant health and air circulation. Old flower spikes can be cut back to the base after blooming has finished to encourage new growth.
Avoid cutting healthy green foliage.
Propagation is typically done by division of mature pseudobulbs during repotting. Carefully separate the pseudobulbs, ensuring each section has at least 2-3 healthy pseudobulbs and some roots.
Pot them individually in a suitable orchid mix.
Repot every 2-3 years or when the potting medium breaks down, typically after flowering. Use a well-draining orchid mix, such as bark chips and perlite. Choose a pot that allows for good air circulation around the roots.
