Stanhopea RadiosaStanhopea radiosa

Water thoroughly when the potting medium is nearly dry, typically once a week during active growth. Reduce watering significantly during the dormant period to prevent root rot.

Ensure good drainage to avoid waterlogged conditions, especially after watering.

Pruning is generally not required for Stanhopea radiosa beyond removing spent flower spikes and any dead or damaged pseudobulbs or leaves. Dead material should be trimmed at its base to maintain plant health and aesthetics.

Propagation is primarily done through division of mature pseudobulbs. Carefully separate the plant into sections, ensuring each division has at least two or three pseudobulbs and healthy roots.

Allow the cut surfaces to callus before repotting.

Repot every 2-3 years, or when the potting medium begins to break down. Stanhopea radiosa prefers a well-draining orchid mix.

Repot after flowering, as they tend to bloom from older pseudobulbs and have a pendulous growth habit.
