Another effective propagation method is the division of rhizomes. This is best done in early spring or fall when the plant is not actively growing. Carefully dig up the rhizomes and separate them into sections, ensuring each piece has at least one bud for successful growth.

⏰ Timing and Conditions

For optimal results, plant the divided rhizomes in well-drained soil within a shaded environment. This will provide the best conditions for the new plants to thrive and establish themselves in your garden.
