Step-by-step guide
- 1
Prepare the Growing Medium
Prepare a fertile, well-draining growing medium using quality potting soil or peat moss mixed with compost and perlite. The growing medium should retain moisture while allowing excess water to drain away to encourage healthy root development.
- 2
Sow the Seeds
Sow the seeds about 0.3–0.5 cm deep, placing 1–2 seeds in each cell or pot. Cover lightly with growing medium and water gently. Keep the growing medium consistently moist until the seeds germinate, usually within 5–10 days.
- 3
Transplant the Seedlings
When seedlings develop 3–4 true leaves and a healthy root system, transplant them into the garden or containers. Space plants 20–25 cm apart to provide enough room for compact heads to develop.
- 4
Water & Feed
Keep the soil evenly moist throughout the growing season without allowing it to become waterlogged. Apply a balanced fertilizer or diluted liquid organic fertilizer every 10–14 days to encourage healthy leaf growth.
- 5
Care for the Plants
Provide at least 5–6 hours of sunlight each day, preferably with some afternoon shade in hot weather. Inspect plants regularly for pests and diseases, remove damaged leaves, and maintain good airflow around the plants.

Harvest
Harvest individual outer leaves as needed, or cut the entire head at the base when it reaches full size, about 45–60 days after sowing. Harvest in the early morning for the freshest, crispiest leaves.
