How to Grow

From seed

Prepare soil with fertilizer.

Sow 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 plant food.

In a pot

Globe artichoke like to spread, so ensure the pot is 1m wide and 30cm deep.

Fill pot with potting mix and plant.

Follow seed -> harvest guide.

Ready to harvest

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 reach under the plant bases and pull out the tubers, they look a bit like knotted plants.

If you've planted Globe artichokes, they're generally ready to harvest in Spring.

Pick the buds when they are firm, but just before they open.

Use a sharp knife to cut the stem and leave a few centimetres of stem,.

Tips for Care

looks_one
Seeds need 20C soil temp to germinate
looks_two
Artichokes are perennials, so they will continue to grow year after year, for up to three or four years.

Cut plants back towards the end of Autumn, and feed with fertilizer as the new shoots appear.
looks_3
If you're growing in a pot, ensure its 1M wide.

Good drainage is essential.
looks_4
Artichokes grow slowly.

They can take more than a year to get to cropping stage.

As they grow, thin out the shoots to leave only three or four of the strongest.

If you don't do this, you'll end up with small, weak heads of artichokes.

Artichokes grow to enormous sizes, don't plant anything within a 1m2 range of the plant.
