Water Tetrapanax regularly, keeping the soil consistently moist but not waterlogged. Allow the top inch of soil to dry out slightly between waterings.

Reduce watering frequency during cooler winter months to prevent root rot. Ensure good drainage to avoid standing water.

Pruning Tetrapanax is primarily done for size control and to remove any dead or damaged stems. Cut back stems to the desired height in late winter or early spring before new growth begins.

Vigorous pruning can encourage bushier growth.

Tetrapanax can be propagated by root cuttings or division of rhizomes. In spring, carefully dig up sections of the rhizome that have at least one bud and a good root system.

Plant these in moist, well-draining potting mix and keep warm.

Repot Tetrapanax every 2-3 years, or when the plant becomes root-bound. Choose a pot that is one size larger than the current one. Use a well-draining potting mix.

Repotting is best done in early spring before active growth begins.
