Tetrapanax produces suckers that spread out from the root system and emerge from the soil near the plant. You can cut and replant these suckers to create new Tetrapanax specimens. The first step in propagation is to expose the root system of the sucker and parent plant using a small shovel or hoe. Select a sucker with an established stem and several leaves growing above the ground. The plant's root sucker is severed from the parent plant at the roots, creating a separate plant consisting of a stem, leaves and roots. Clean any soil from the roots of the sucker and place it in a pot partially filled with potting soil. Fill around the roots until they are completely covered. Use a pot that accommodate the future growth of the sucker and grow it in the pot until the following spring, to allow ample time for it to establish a new root system.
