Artichoke plants may need to be staked for support as they grow. Use a sturdy stake and tie stems gently to it using twine or plant ties.
If growing artichokes as perennials, cut plants to ground level after harvesting or when the leaves begin to yellow in autumn. Apply a thick layer of organic mulch around the stems.
Common Problems: Aphids, Powdery mildew, Slugs and snails
The globe-shaped flower buds (also sometimes called 'heads') are the part of the plant that is harvested. The entire flower bud is harvested but only the tender center of the bud (called the 'heart') is eaten.
The flower buds are ready to harvest when they reach full size and the bracts (the outer leaves surrounding the bud) just begin to open. Cut the buds from the stem using snips/secateurs, leaving 5cm of stem attached to the bud.
Eat artichoke as soon as possible after harvesting.
Store buds short term in a perforated plastic bag in the fridge. For longer term storage, whole buds or hearts can be blanched in acidulated water and frozen or hearts can be pickled or preserved in oil.
