Soaking time: Before planting radish, soak the seeds in water for about 30 minutes. If soaked for too long, the seeds may lose their activity. Method of accelerating germination: treat seeds with 25% hydrogen peroxide solution, take them out after half an hour, rinse them with water, cover them with wet cloth and accelerate germination. Planting method: Sow the treated seeds into the soil, cover with thin soil, and the seedlings will grow together in a week or so.
