How to prune catasetum orchid

Late autumn to winter, once leaves have dropped and the plant is dormant. Remove spent flower spikes at their base and peel away dead dried leaf sheaths from pseudobulbs. Use sterilised scissors. Do not water during dormancy unless pseudobulbs shrivel severely. Repot and divide at the start of new growth in spring.

Annually at the start of dormancy. Catasetum orchids are deciduous — they drop their leaves naturally each autumn as they enter dormancy. This is normal, not a pruning trigger. Once the plant is leafless and dormant, remove any spent flower spikes and dead brown leaf bases. Do not cut living pseudobulbs. Resume normal watering when new growth tips emerge in spring.
