Choose a location with light to medium soil that is moist. Ensure good drainage.
Direct sow seeds 1 cm deep, spaced 30-45 cm apart. Transplant young plants in the same spacing.
Water regularly to keep soil moist but not waterlogged. Monitor for pests and diseases.
Provide full sun, regular watering, and occasional fertilization with compost. Mulch around plants to retain moisture.
Prune dead leaves and stems to encourage new growth and maintain plant health.
