Soil facts and preparation

Quick facts..

  • Soil Type Fertile and Well Drained
  • Ideal Ph range 6.5 to 8.0
  • Site Full Sun
The site you choose for growing globe artichokes will be occupied by these large plants for 2 to 3 years. While the plants will live for longer, older plants tend to produce fewer, smaller buds. For the best flavored artichoke hearts, pick a spot in full sun.

The soil needs to drain well and contain plenty of organic matter for the large hungry plants to prosper. Dig in plenty of well rotted manure or fresh garden compost. For an added boost to soil fertility you can optionally add a fertilizer low in nitrogen and high in potassium and phosphorus.

Sowing and planting

Quick facts..

  • Germination 7 to 12 days
  • Sow 10mm deep
  • Sow Spacing 200mm
  • Rows 300mm apart
If you do chose to start from seed sow 2 or 3 seeds in pots of fresh compost with a view to planting out after the risk of any frost has passed.

Alternatively plants can be bought in containers and planted out. Look for healthy plants and plant in meter square spacings.

Growing a bumper crop

The soil needs to be kept moist in the summer and dry in the winter, any summer drought will affect the number and size of the flower buds.

Keep surrounding soil free of weeds, mulching in spring will help suppress the weeds and aid moisture retention. Top up mulch again before winter to protect the plants from cold weather.

Plants will not usually flower in the first year. Allow only four to six heads to develop on each new plant and remove extra buds from side shoots.

Harvesting the fruits of your labour

Quick facts..

  • Yield 340g per plant
Starting with the main bud of the stem, cut when just bigger than a golf ball and before the buds open and start to flower.

When the flower heads start to turn purple and start to open they become inedible.
