How do you start an artichoke indoors?
Start indoors in late winter, four to six weeks before the last frost date. Keep seedlings under bright lights. Sow two seeds per pot, 5mm (¼”) deep. Keep moist in a warm place until seeds germinate in 10 to 21 days.
How long does it take artichoke seeds to germinate?
To begin germinating, artichoke seeds need a temperature around 70 to 75 degrees F. (20 C.) and will take two to three weeks to sprout; another thing that should be taken into account when deciding when to start your artichoke plants.
How do you germinate an artichoke seed?
Plant seeds ¼ inch deep in seed starting mix. The soil temperature must be 60 to 80 degrees for the seeds to germinate, so a heated seed-starting mat can be used to ensure the proper temperature. In 10 days to three weeks, the seeds will germinate.
Are artichokes difficult to grow?
With long, silvery leaves and strikingly attractive blooms, the artichoke is a unique addition to your vegetable garden. Growing artichokes isn't difficult, and with the proper planting, watering and pruning, you can enjoy a bountiful harvest of edible chokes.

When should I transplant my artichoke seedlings?
Transplanting artichokes is best done in early spring. If starting from seed, transplant seedlings out around 2 or 3 weeks after your average last frost date. Transplanting mature plants or removed pups (offshoots) off mother plants is also best done in spring, but can be done any time of the year outside of winter.
How long does artichoke take to grow?

What temperature do artichokes grow in?
Temperature and Humidity
When grown as perennials, artichokes favor areas with mild winters (50 to 60 degrees Fahrenheit) and cool, moist summers (70 to 80 degrees Fahrenheit). Very hot soil will make the plants flower too quickly, so apply a thick mulch around the base of the plants to keep the soil cool.
Can you winter sow artichokes?
Sow seed in late winter, giving plants 8 to 10 weeks to grow before you move them outdoors. In USDA Zones 7 and warmer, artichokes are perennials that first produce buds in their second year, but in the North we need to fool the plants into producing in the first season.
Can you root an artichoke?
Modern-day gardeners wishing to cultivate artichokes in other climates can do so by planting artichoke from seeds and growing them as annuals. Rooting artichoke cuttings is another method of artichoke plant propagation and is used in areas where they can be grown as perennials.
How do you stratify artichoke seeds?
Sowing: Stratify seeds by putting them in damp sand in the fridge for 2 weeks. Then germinate seeds indoors 8-12 weeks before last frost. Plant them 1/4" deep, in 4" pots, and keep the seedlings at a temperature of 60-70 degrees.
Can I grow an artichoke from an artichoke?
Yes, you can. But you're limited to only Jerusalem artichokes, which will grow like weeds if you give them the love they need. As for traditional artichokes, you can't. You'll need to either propagate them from seed, root cutting, or from the nursery as a transplanted plant.
