How to prune free-flowering cymbidium

After each flowering cycle, typically late spring. Sever spent spikes at their base with sterile secateurs. Remove leafless backbulbs at the rhizome. If the clump is very crowded, divide it at repotting time rather than pruning — division refreshes vigour more effectively.

Annually; divide overcrowded clumps every 3–4 years. Free-Flowering Cymbidium produces multiple spikes and benefits from prompt post-bloom pruning to maintain vigour across repeated flowering. Cut each spent spike at the base as soon as all flowers are finished. Thin out leafless old pseudobulbs annually to improve light penetration and encourage the new growths that will produce next season's spikes.
