Growing And Caring For Tetrapanax

Propagation Methods For Tetrapanax Papyrifer ‘Rex’

Propagation of tetrapanax papyrifer can be done by the seed or from the shoot produced by the underground root system.

Starting a tetrapanax in containers indoors allows for an early start in the growing season and results in more mature specimens that can then be replanted outside. Plant your seeds in fertile and fast-draining soil like loamy or sandy soil at a depth equal to the length of the seeds. Water thoroughly till it germinates and continue to water the plant to keep the soil moist. 

Tetrapanax papyrifer ‘Rex’ propagation from side shoots / pups : As mentioned earlier, tetrapanax produces pups from the root system. These shoots can be cut off from the parent plant and then replanted to form a new tetrapanax plant. To do this, use a shovel to expose the root system of both the parent plant and sucker then select a sprouting sucker with established leaves above ground and severe it from the parent plant at the roots. This creates a separate specimen with a root system, stem, and leaves. 

Tetrapanax plug plants: Tetrapanax is generally not commonly bought as a plug plant, as it’s generally sold as at least a year old plant (so it has established roots)
