How do I care for Gravel Root?
Gravel Root thrives in moist, well-draining soil and prefers full sun to partial shade, ideally at least 6 hours of direct sunlight daily. Water regularly, especially during dry periods, keeping the soil consistently moist but not waterlogged. Fertilize in early spring with a balanced fertilizer to promote healthy growth and abundant blooms. Deadhead spent flowers to encourage further flowering and prevent self-seeding if desired.
How do I propagate Gravel Root?
Gravel Root can be propagated through division, stem cuttings, or seeds. For division, carefully dig up the plant in early spring or fall and separate the root ball into smaller clumps, ensuring each clump has healthy roots and shoots. Replant the divisions in well-prepared soil. For stem cuttings, take 4-6 inch cuttings from new growth in late spring or early summer. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cuttings in moist potting mix and keep them humid until rooted. Seed propagation involves sowing seeds in spring or fall and keeping them moist until germination. Seeds may require stratification (cold treatment) for optimal germination.
