How to Grow Artichokes:

Artichokes do best in cool weather and are usually planted indoors and transplanted outdoors. They grow best in humid areas where temperatures remain below 50°F for extended periods. Start seeds indoors 6 to 8 weeks before setting outdoors. Plants require temperatures of 50°F to 70 F temperatures to induce budding. Spring planting should occur as soon as the soil can be worked and after the last frost, and fall planting should be done in September, October, and November for a spring harvest. When seedlings are 2" to 4" tall, transplant them into larger pots so roots can grow properly. Protect the plants from frost. Plants become less productive in the 5th and 6th year, and new plants should be grown. Plants can grow 3 to 5 ft tall.

Soil Requirements:

Requires fertile soil in a well-drained location in the garden. Apply mulch and grass clippings, or straw around the base of the plant.

Water Requirements:

Keep seedlings and transplants consistently moist. Water well during dry and hot spells.

Fertilizer Requirements:

Use RootBlast, Vegetable Alive, and Slow Release Fertilizer when transplanting outdoors. Periodically apply Miracle-Gro.

Harvest Tips:

Cut the edible flower buds when they are 3 to 4" in diameter. After harvesting, cut the plant back one-third to encourage new buds to form.
