Every so often I get a call to divide Cymbidium Orchids. I'm no orchid expert. But Cymbidiums are usually fairly easy. They do like to be crowded. But when they get so much dead growth and are climbing out of their pot, it's time to divide. You can make more plants to keep or give away.
I pull the plant out of the pot and rip it apart! This one was so big and root bound that I needed to use my shovel to slice the middle of the roots. Then I butterflied it, open, ripped out the dead stuff and made one plant into three.
