Growing Information


CULTURE: Artichokes require very fertile, well-drained soils with a pH of 6.5–8.0. Sow artichokes indoors 8–12 weeks before last spring frost date. Sow 2-3 seeds per cell in plug trays or individual containers ¼" deep. Germinate at 70–80°F (21–26°C). As soon as seedlings can be handled, transplant to 4" pots or 72-cell plug flats, if necessary, and grow at 60–70°F (15–21°C) during the day and 50–60°F (10-15°C) at night. Transplant 6- to 12-week-old plants to the field 2–3' apart in rows 4–6' apart.
MILD AREAS: Where winter low is above 14°F (-10°C), sow seeds in fall, harvest in spring.
IMPORTANT COLD TREATMENT (VERNALIZATION): Time transplanting so plants receive 10 days of 45–50°F (7.2–10°C) temperatures to induce earlier budding. Protect from frost.
HARVEST: Clip mature buds midsummer to midfall, depending on location.
SEED SPECS: SEEDS/LB.: Avg. 11,500.
PACKET: 25 seeds, unless otherwise noted.
