Growing ArtichokesFrom Seed: A Comprehensive Guide

Artichokes, with their unique appearance and delicious taste, are both an ornamental and culinary delight. Originating from the Mediterranean, these perennial plants have found their way into gardens across various climates, thanks to careful cultivation practices. Here's how you can grow your own artichokes:

Understanding the Artichoke

The globe artichoke (Cynara scolymus) is not just a vegetable but also an attractive plant with silvery-green, lobed leaves that resemble a giant fern. The edible part is the immature flower bud, which, when cooked, offers a tender heart and the base of the petals. Artichokes thrive in USDA zones 7-10 but can be grown as annuals in cooler zones with the right precautions.

Planting Artichokes

  • Location: Choose a spot with full sun, at least 6-8 hours daily. The soil should be well-draining but moisture-retentive, with a pH between 6.0 and 8.0.
  • Starting from Seed: Start seeds indoors 10-12 weeks before the last expected frost. Artichokes need warmth for germination, so using a heat mat or placing them in a warm location can help.
  • Sowing Depth: Sow at a depth of 1/2" under topsoil.
  • Transplanting: Once the danger of frost has passed, transplant seedlings or shoots into the garden. Space plants 3-4 feet apart to allow for their significant growth.

Care and Maintenance

  • Watering: Artichokes require consistent moisture, especially during bud development. Using soaker hoses can help maintain soil moisture without wetting the foliage excessively.
  • Mulching: Apply mulch around plants to keep the soil cool during hot summers, which can prevent premature flowering.
  • Fertilization: Feed with a balanced fertilizer monthly during the growing season. Compost can also be used as a natural fertilizer.
  • Pruning: Remove old leaves and spent buds to encourage new growth. In cooler climates, cut back plants after the first frost to about 6 inches above the ground.

Overwintering and Division

  • In Zones 7-10: Artichokes can overwinter in the ground with protection. Mulch heavily around the base after cutting back.
  • In Colder Zones: Dig up the roots in fall, store them in slightly moist sand in a cool, frost-free place, and replant in spring.
  • Division: Every few years, divide the plant by cutting offshoots from the main root mass in spring. This rejuvenates the plant and helps control its size.

Pests and Diseases

  • Aphids and Slugs: These are common pests. Regularly inspect under leaves, and use water jets to dislodge aphids or employ natural predators like ladybugs. For slugs, consider using beer traps or diatomaceous earth.
  • Diseases: Watch for botrytis (grey mold) in damp conditions. Good air circulation and avoiding overhead watering can mitigate this.

Harvesting

  • When to Harvest: Buds are ready when they're firm and tight. Typically, this is 85-100 days from planting for annual types. The main bud is at the top, with smaller ones below.
  • How to Harvest: Use a sharp knife to cut the stem with the bud, leaving a few inches of stem attached.

Culinary Use

Artichokes are not only delicious steamed or boiled but also grilled or roasted. The heart and the base of the inner leaves are particularly prized for their taste.

Conclusion

Growing artichokes can be a rewarding endeavor, offering both aesthetic garden appeal and a gourmet treat. With proper care, even gardeners outside the traditional Mediterranean climate can enjoy this unique plant's bounty. Remember, patience and attention to detail are key, as artichokes require a bit more care than common garden vegetables but are well worth the effort for their unique flavor and beauty.
