How to prune cattleya 'why not'

Remove spent flower spikes at the base of the sheath once blooms have dropped. Leave all pseudobulbs intact, including older back-bulbs that still show green. Only remove fully desiccated back-bulbs. Repotting every 2–3 years manages plant size more effectively than pruning.
