When should I start my artichoke seeds?
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.
Is it difficult to grow artichokes from seed?
Growing Artichokes from Seed is easy, just be sure to do the right thing at the right time. Seedlings are transferred to a heating mat in the cold greenhouse after a month indoors, were temps near the roots are kept at 75º F but air is maintained at 50º.
Should you soak artichoke seeds before planting?
Soak them overnight in water, drain and place in a jar filled with moist sand before refrigerating. Or you can vernalize them naturally by setting your seedlings outside in a cold frame or other protected area while the temperature is in the 34-degree-to-50-degree range for a week or more.
How do you plant artichoke seeds?
To plant: Artichoke seeds can be started in February in a greenhouse or under a fluorescent light, planted about 1/4-inch deep in 4-inch containers. Artichokes are known as tap-rooted plants, which means their roots grow deep, even as seedlings. Be sure to plant the seeds in a deep container.
Do artichokes produce the first year?
It’s capable of budding in the first year, produces as an annual in climates as cool as Zone 3 and is still able to handle warm summers as a perennial. It reaches harvest early – at only 75 days.
Can you direct sow artichokes?
Your artichokes can be grown as short lived perennials and seed should be sown directly into the garden in the fall. When to start seeds is key to healthy flower head production. They will grow into large, bush-like plants that need a very long growing season.
Do artichokes need full sun?
Artichokes thrive in full sun to partial shade. They also need light, fertile, well-drained soil—sandy or loam is ideal. Two reasons artichoke plants fail are summer drought and winter soil that’s waterlogged. Adding compost will improve the soil’s ability to retain water in summer and to drain in winter.
When should you plant artichokes?
Artichokes are planted at different times of the year, depending on the climate. Where they are grown as annuals, they must be planted in spring. In warmer zones where they survive as perennials, they are often planted as seeds in late summer or as young plants (or transplants) in mid-autumn.
Can you grow an artichoke plant 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.
When can you transplant artichokes outside?
Transplant seedlings to the garden when plants are 6 to 8 weeks old and outdoor temperatures are at least 50°F (10°C) at night. Set out root divisions or “crowns” in late winter if the soil is easily worked or early spring about 2 weeks before the last frost.
How do you harden an artichoke?
Six weeks before your last frost date, start hardening off seedlings by gradually exposing them to bright sun, wind and cool temperatures. Set artichoke plants out in prepared beds 3 to 4 weeks before your last frost date. Exposure to cool temperatures below 45 degrees is necessary to trigger flowering.
Do artichokes like hot weather?
The plant grows best in cool, mild climates. When it receives careful attention and adequate moisture, however, an artichoke plant grows successfully in hot climates. Artichoke varieties that tolerate hot weather include Green Globe, Emerald, Purple Sicilian, Imperial Star and Madrigal.
How deep do artichokes need to be planted?
How to Plant Artichokes. Space each plant three to four feet apart in rows and leave four to five feet between the rows. Plant the shoots and dormant roots about six inches deep. The tops should be above ground level.

Where do artichokes grow naturally?
Warm climate. Artichokes grow naturally in the Mediterranean, with mild summers and cool winters, so they grow well as outdoor perennials in most of the United States—anywhere in USDA hardiness zones 7 or warmer (though hot Southern summers can be hard on the plant). Cold climate.
Can you grow artichokes in Zone 5?
With proper artichoke winter care, this perennial is hardy to USDA zone 6 and occasionally zone 5 during mild winters. Artichokes can grow and produce for up to seven years, making it beneficial to protect artichokes in winter.
