Cardoon

Cynara cardunculus

INTRODUCTION

Cardoons or Cardon, related and similar in appearance to Globe Artichokes, are grown for their stalks and midribs (traditionally blanched before harvest) instead of the flower buds being consumed. When grown well, and after blanching for several weeks and prepped in the kitchen, the finished article resembles sticks of Celery and have an Artichoke-like flavour.

This leafy frost-tender perennial originates from the Mediterranean and North Africa. It may not be everyone's favourite vegetable, but if you fancy something a bit different Cardoons could be for you.

Soil Preparation

Cardoons require well-drained, fertile soil preferably in a sheltered position away from prevailing winds.

They will be at their happiest in full sun.

Prepare the ground by incorporating well-rotted manure or garden compost into the soil.

Sowing & Planting

Plants can be put out into their final growing positions from April until August.

If sowing seed, this can be carried out during spring.

Either sow in situ or as an alternative, raise seedlings undercover and when large enough to handle prick out into 9cm pots.

Harden fully before planting out.

Cardoon plants are sizable when fully mature and need plenty of space.

Plant at 90cm (36 inches) spacings between plants and rows.

Growing & General Cultivation

Allow plants in their first growing season to fully establish. Remove any flowering spikes in year one to enable the plant to put all of its energy into rooting.

Keep plants weed-free and well-watered during the growing season.

Mulch well to conserve moisture.

Feed as necessary.

During the summer and before harvesting (at least 6 weeks before) gather up the foliage and tie together. Surround the gathered bundle with cardboard to blanche the foliage inside. This blanching process makes the resulting stems less bitter when eaten.

In the autumn, plants will naturally die down like any other perennial plant and all foliage can be cut away and removed.

If severe weather is forecast, mulch plants to protect roots, especially while plants are young.

Pests & Diseases

Cardoons, in general, are trouble-free. The odd issue may arise:

Slugs and Snails can be a problem for young plants and emerging growth in the spring. For remedies - see product directory.

Powdery Mildew is a white powdery deposit that can cover stems and foliage. It is usually associated with dry weather and to prevent, avoid plants from drying out. Remove affected foliage as needed or in severe outbreaks, use a suitable fungicide - see Product Directory.

Black Fly can sometimes attack the developing buds, especially during warm weather. Spray with an organic pesticide - see Product Directory.

Harvesting

After 6 weeks of blanching, the Cardoons should have taken on a pale colouration and be less bitter in taste.

Remove the stems and strip the foliage leaving what looks like sticks of Celery.

Always consume fresh.
