How to prune zygopetalum 'redvale'

After blooming for spike removal; at repotting (every 2–3 years) for old pseudobulb cleanup. Cut finished flower spikes at their base with a sterilised blade. At repotting, remove fully dry, leafless back-bulbs by cutting at the rhizome. Dust any cut surfaces with cinnamon or powdered sulphur to deter rot.

As needed — once per bloom cycle; back-bulb cleanup every 2–3 years. Zygopetalum 'Redvale' needs very little pruning. Remove spent flower spikes at the base after all blooms are finished. Old, completely leafless pseudobulbs can be detached at repotting time. Do not cut healthy pseudobulbs or green foliage — the plant relies on them for nutrient storage and future flowering.
