Frostproof
Sow as early as possible in frost-free soil or in August for overwintering, 2 - 3 cm deep with 30 cm row spacing. Lay seeds flat, cover with soil and keep moist. Separate vigorous plants to 5 - 10 cm apart. Likes sunny to semi-shady locations and sandy-humic, deep loose soil, not freshly fertilized. Keep evenly moist. Do not damage roots when harvesting, twist off leaves and store wrapped vertically in sand. Harvesting possible even after frost, as winter-hardy.
