Start with Narrow Leaved Peppergrass to gain experience in growing Brassicaceae plants.
Seeds, a small trowel or scoop, and containers or garden space.
Plant in spring after the last frost or in late summer for fall harvest.
Ensure soil is well-draining with a pH between 6.0 and 7.5, and prepare containers with good drainage holes.
Direct sow seeds 1/4 inch deep in rows spaced about 30 cm apart, or start indoors and transplant seedlings after they have two true leaves.
Keep soil consistently moist and provide light shade if direct sunlight is intense.
Water regularly to keep the soil moist but not waterlogged, and mulch around plants to retain moisture. Thin seedlings to 15 cm apart as they grow.
