Globe Artichoke is a perennial, so will come back year after year - therefore plant them in a permanent position.
They grow to approx 1m so need a bit of space. Plant 1-1.5m apart.
Choose a sheltered, sunny site with well drained soil.
They look great in beds and borders.
Water plants well until established and make sure they don’t dry out in hot weather.
In the first year your artichoke plants need to put all their energy into making growth, so remove any flowerheads as they form.
In the second year, allow the edible heads to develop for harvesting in summer.
If you want to provide food for bees, allow some of the artichokes to flower
Cut back stems in late autumn (after they have finished flowering) and protect the remaining crown over winter with a thick mulch of straw or other material. They’ll grow again the following year. In mild areas, they may even produce new growth in autumn and winter.
Problems & Pests:
Earwigs - can often live in the fruits. Try rolling newspaper and dampening it, then leave near the base of the plant. If fruits are affected, try soaking them in a bowl of water with splash vinegar for a few minutes, then rinse out before cooking.
Aphids/blackfly - small black bugs may gather in clusters on stems and stalk. Hose them off, or cut off the affected foliage if possible. Find something yellow and sticky to deter them - e.g. a yellow bucket smeared with vaseline.
Small fruits - not enough water during summer months/fruiting season. (Fruits also tend to be small in the 1st year of growth - next year’s will be bigger.)
Harvest from the second year onwards, in summer. Start with the top bud first, when it’s large and swollen, but before the scales have started to open.
Pick the side buds when they have reached a decent size.
Some fruits will have sharp, spiky scales, so be careful.
They will only store for a day or two at room temperature, and are much the best eaten freshly harvested.
