When cymbidiums finish flowering, large plants can be divided. Proper care yields healthy cymbidiums that bear plenty of colorful flowers. Once flowering ceases is an ideal time to divide overgrown specimens.
Cymbidiums are easy to grow but often difficult to divide.
Dislodging a clump firmly established in its container may require breaking the vessel. Miniature hybrids often do well for five or six years before needing division and repotting. By then, a multilead clump is huge. To dislodge a specimen, turn the pot upside down on the edge of an outdoor bench and slap the pot on the top and sides. The vibration usually loosens roots adhering to the container's walls.
