Cymbidiums are terrestrial orchids (grow in the earth); they develop long spikes with many flowers. They have grass-like leaves as opposed to paddle leaves on moth orchids. Over time, many dead (or back bulbs) remain in pot and pull energy from the new and good bulbs. The plant needs to be extracted from the pot and divided to create new plants. Remove old dead bulbs and potting material, dead roots, and trim roots back.
Keep bulbs in groups of 3 or more. If you have only 1 or 2 it may take longer to bloom.
Always sterilize your tools when working with these plants. They can become infected.
