Start indoors 6-8 weeks before last frost, harden off 3–4 days, then transplant after last frost. Ideally, place in a heated propagator or cover with a polythene bag and keep at 70˚F (20°C.) Seed is very fine so mix some with horticultural sand to make it easier to handle. Keep watering of plants to a minimum as seedlings are prone to ‘damping off’ and always water from the bottom. After first year cut plants back each spring to renew growth, fresh form is more flavorful. Leaves are used and stem is commonly discarded. Harvest starting the second year. Once established can be picked all year. Replace after about five years, cuttings are easy to root. Surface sow, press into soil, do not cover. Soil pH 6.1-8.5. Hardiness zones 4-10. Perennial.
