How to grow artichoke at home:
Planting artichoke is very simple but you just need to make sure that the soil is well prepared.

  1. Start by preparing the garden bed with organic compost and soil improver and plant fertiliser. If soil is acidic, mix in a small amount of liquid lime and dolomite before planting.
  2. Sow your artichoke seeds, suckers or tubers directly where they are to grow, cover lightly with seed raising mix, gently firm down and keep moist. Thin seedlings to 60cm apart and feed every two weeks with liquid plant food.

How to grow artichoke in pots:
Can you grow artichokes in pots? Yes you can! You just need a pot 30cm or wider.

  1. Globe artichokes like to spread, so ensure the pot is 1m wide and at least 30cm deep. Fill pot with a quality potting mix enriched with dynamic lifter and plant artichoke seeds or tubers.

When to harvest artichoke:
Jerusalem artichokes are usually harvested five to six months from planting. If you’ve planted Jerusalem artichokes, in autumn the plants begin to die back and, when they’re completely brown, the harvest can begin. Use your hands to ‘bandicoot’ under the plant bases and pull out the tubers.

Globe artichokes, on the other hand are generally ready to harvest in spring. Pick the buds when they are firm, but just before they open. Tip: Use a sharp knife to cut the stem and leave a few centimetres of stem.

Storing artichoke at home:
Storing artichokes can be a little difficult. Raw artichokes do not keep well and should be eaten right away. If not eaten fresh artichokes should be refrigerated. Place artichokes in a plastic vegetable bag and used as quickly as possible. Cooked artichokes can be kept in the refrigerator for 2-3 days.

Artichoke care and common problems:
Plants can be affected by caterpillars, nematodes, slugs and two-spotted mites and the tubers must be handled with care as the skin is thin and easily bruised.

Water the base of the artichoke plant, early in the day so the leaves have time to dry before nightfall; this will help keep the plants disease free.
