- Division: Splitting established plants in spring or fall helps rejuvenate older plants.
π Step-by-Step Instructions
For seeds: Sow them in well-draining soil, lightly cover with soil, and keep moist until germination occurs.
For cuttings: Cut 4-6 inch stems from healthy plants, remove the lower leaves, and place them in water or soil until roots develop.
For division: Carefully dig up the plant, separate it into sections, and replant immediately to ensure they thrive.
By following these methods, you can easily expand your Bugleweed collection and enjoy its beauty in various parts of your garden. Whether you choose seeds, cuttings, or division, each method offers a rewarding experience in nurturing new life.
