Seeds or young plants, a container with drainage holes, potting soil.
Plant in spring after the last frost, or start seeds indoors about 4 weeks before planting outdoors.
Use well-draining soil with a pH between 6.5 and 7. Ensure your container is at least 30 cm deep.
Direct sow seeds 1-2 cm deep, spacing them about 15 cm apart. Transplant young plants when they have several leaves.
Keep the soil consistently moist and provide partial shade to help seedlings establish.
Water regularly, especially during dry spells, and mulch around the base for moisture retention. Fertilize lightly every 4-6 weeks.
Pinch back shoots to encourage bushy growth and prevent leggy stems. Harvest leaves as needed throughout the growing season.
