How to grow cymbidium orchids from bulbs?

Cymbidium orchids grow from pseudobulbs (storage organs), not true bulbs, and propagation is straightforward! I've divided my plants for years:

The best time to divide is after flowering when new growth appears. Remove plant from pot and gently separate the pseudobulbs. Each division should have at least 3-5 healthy pseudobulbs with roots.

Use sterile tools to cut through connecting rhizomes. Dust cuts with cinnamon or fungicide. Pot each division in fresh orchid mix (pine bark chips). Water lightly initially, then normally once new roots establish.

Don't divide too small - larger divisions recover faster and flower sooner. The back bulbs (oldest, leafless pseudobulbs) can also be potted separately - they may produce new growth but take longer.

They like being slightly crowded, so only divide every 3-4 years when pots become full.
