Watering, pruning, propagation, and repotting details from plant data
Water thoroughly when the potting medium is nearly dry, typically once a week. Ensure excellent drainage to prevent root rot.
Reduce watering significantly during the cooler, dormant winter months, allowing the potting mix to dry out more between waterings to encourage blooming.
Remove spent flower spikes after blooming. Cut them back to the base of the pseudobulb. Dead or damaged leaves and roots can be trimmed at any time of year to maintain plant health and prevent disease.
No other regular pruning is typically necessary.
Propagate Prosthechea radiata through division.
When the plant becomes overcrowded, typically in spring, divide the pseudobulbs into sections, ensuring each section has at least three healthy pseudobulbs and a good root system.
Replant divisions immediately into appropriate orchid medium.
Repot every 1-2 years, or when the potting medium begins to break down. Choose a well-draining orchid mix, such as bark or sphagnum moss. Repot after flowering, preferably when new root growth is evident.
Avoid disturbing the roots excessively.
