Fill a flowerpot with soil.
Make a small hole in the soil with a tip of a pen, approximately 2 mm deep.
Put one seed in the hole. Do not cover the seed with soil.
Water the soil thoroughly.
Cover the pot with thin transparent plastic.
When the seed begins to grow, remove the plastic (takes about 7–10 days). Once the seed has begun to grow, water as needed. Must be moist but not wet.
After the seed pod has fallen off (at about 14 days), add plant fertilizer to the water and water the plant once a week.
Let the plant grow to a height of about 20 cm before planting it out in the garden. The best time to do this is in the spring.
