Key traits and growing stats from plant data
Watering, pruning, propagation, and repotting details from plant data
Water thoroughly when the growing medium is nearly dry. Avoid waterlogged conditions, which can lead to root rot. Reduce watering slightly during cooler months when growth slows.
Ensure good drainage to prevent moisture buildup around the roots.
Remove spent flower spikes and any dead or yellowing leaves. Trim away overcrowded pseudobulbs to improve air circulation and plant health. Pruning encourages new growth and helps maintain a tidy appearance.
Propagate by division when the plant has outgrown its pot. Separate healthy pseudobulbs with at least two leaves and a healthy root system.
Allow the divisions to air dry for a day or two before repotting into a suitable orchid mix.
Repot every 1-2 years or when the potting medium begins to break down. Use a well-draining orchid mix, such as bark or sphagnum moss.
Repot after flowering, typically in spring, to minimize stress and allow roots to establish.
