Vegetable Garden - Tips on Growing Artichoke From Seeds

The objective is to convince the Artichoke plant that it is two years old and ready to make buds, rather than a seedling ready to make only leaves. This is done by growing the plant at cool temperatures for a prescribed length of time. This cold treatment makes the seedling behave as if it is an older plant ready to flower.

Before you use the cold treatment here is information for sowing the seed.

Sowing the Artichoke Seeds

  • Artichoke Seed Depth: " (6mm)
  • Germination soil temperature: 70-80F (21-27C)
  • Days to Germination: 10-14

Sow Indoors:

  • Late winter to early spring- 10 weeks before last frost.

Sow outdoors: Not recommended.

Growing Artichoke Seeds:

  • pH range: 6.5 - 8.0
  • Growing soil temperature: 60-75F (16-24C)
  • Spacing in beds: 24" (60 cm)
  • Watering: Heavy
  • Light: 8 hours or more per day
  • Nutrient requirements: N=high, P=high, K=high
Temperatures during the cold treatment should remain below 50 F (10 C) but above 35F (2 C) for at least 250 continuous hours (about 10 days). Since it is difficult to prevent times when temperatures rise above 50 F (10 C) give the plant the cold treatment for an even longer period, let's say from four to six weeks.

Put the plants in a cold frame about six weeks before the last frost based on your location and zone. When all danger of frost is past and the soil temperature is above 60F (16C) set plants about 2 feet apart in the bed.
