Start with Tsi by planting it in a moist, shady spot and providing basic care.
A few Tsi plants or seeds, a container if needed, and some compost.
Plant Tsi in spring or early summer for the best results.
Use well-draining soil with a mix of light (sandy), medium, and heavy (clay) textures. Ensure containers have drainage holes.
Direct sow seeds in the ground or start them indoors 4-6 weeks before planting outside. Transplant seedlings when they are about 2 inches tall.
Keep soil consistently moist and provide partial to full shade. Monitor for any signs of stress or pests.
Water regularly, especially during dry spells, and mulch around the plants to retain moisture. Prune occasionally to maintain shape and encourage new growth.
Prune Tsi after flowering to promote a bushy habit and remove any dead or yellowing leaves as needed.
Overwatering, planting in full sun, neglecting regular pruning, using too much fertilizer, and not providing enough shade.
