How to Divide Sinningia Tubers

Sinningia is a genus of flowering plants in the gesneriad family. Most Sinningias, such as the Sinningia speciosa varieties (gloxinias), grow from underground storage structures called tubers. No matter what kind of Sinningias you have, they self-propagate and multiply. The tubers can be dug up, divided and replanted in the early summer or late spring -- but note that success is difficult, which is why sinningias are usually propagated from leaf cuttings.

1. • 1

     Dig up sinningia tubers with a shovel, spade or garden fork. Dig carefully around the clump of flowers about 2 inches deep, getting underneath the tubers so that you don't damage them. Gently lift the tubers out of the soil.

     Shake off the excess soil. Wash away the remaining dirt with water, if desired, so that you can better see what you're working with.

     Pull apart the tubers with your hands. Separate them with a sharp utility knife if necessary. Make sure each tuber has at least one growth point. Replant the divided tubers soon as possible.
