Globe Artichoke
Cynara cardunculus var. scolymus
Globe artichokes are as much an architectural garden feature as they are a crop — their dramatic silvery-grey foliage and enormous thistle-like flower heads make a statement in any planting scheme. The edible part is the immature flower bud, harvested before it opens, when the thick fleshy scales and tender heart are at their best. Each plant produces 6–10 heads per season from June onwards. Cut the main head first (it's the largest), and the plant will produce smaller side heads over the following weeks. 'Green Globe Improved' is the most commonly grown variety in the UK. Plants are perennial, cropping for 4–5 years before needing replacement. They prefer sunny, sheltered spots with well-drained soil. Mulch heavily in autumn in colder areas to protect the crowns over winter. Propagate by dividing established clumps in spring — select the healthiest outer shoots.

Common Problems with Globe Artichoke
Earwigs in flower heads
Earwigs crawl into the tightly packed scales of artichoke heads, hiding in the crevices. Shake harvested heads vigorously over a bucket of water before bringing them indoors. You can also trap earwigs by placing upturned pots stuffed with straw on canes near the plants — the earwigs hide inside and can be emptied away each morning.
Aphids on young growth
Black and green aphids often cluster on the tender young shoots and around developing flower buds in spring, weakening growth and potentially spreading viruses. Blast off with a strong jet of water from the hose, or spray with diluted washing-up liquid. Encouraging natural predators like ladybirds and hoverflies provides the best long-term control.
Winter crown damage
Artichoke crowns can be damaged or killed in harsh winters, especially on exposed sites or heavy clay soils where water sits around the roots. In autumn, cut back spent stems and pile a thick mulch of straw, bracken, or bark (at least 15cm deep) over the crowns. In very cold areas, cover with fleece as well. Remove the mulch in spring as new growth appears.

Cherry Tomato
Solanum lycopersicum var. cerasiforme
Cherry tomatoes are one of the most rewarding crops for UK allotment growers. These small, sweet fruits ripen reliably even in cooler summers, producing heavy trusses from July right through to October. They thrive in grow bags, pots, or directly in the ground, making them versatile for any plot size. Pinch out side shoots regularly on cordon varieties to channel energy into fruit production. Bush varieties like 'Tumbling Tom' need no training and work brilliantly in hanging baskets. Feed weekly with a high-potash tomato feed once the first fruits set. The key to great flavour is letting them ripen fully on the vine rather than picking early.
Beefsteak Tomato
Solanum lycopersicum
Beefsteak tomatoes produce the large, meaty fruits that are perfect for slicing into sandwiches and burgers. They need a long growing season in the UK, so starting seeds early under cover is essential. These are almost always grown as cordons — train them up a single stem, removing side shoots weekly. Each truss produces fewer but much larger fruits than cherry types, often weighing 200–500g each. They benefit from greenhouse growing in cooler regions, though sheltered outdoor spots in the south can produce good results. Consistent watering is critical; irregular watering causes blossom end rot and fruit splitting. Stop the plant at 4–5 trusses to ensure fruits ripen before autumn.
Nantes Carrot
Daucus carota
Nantes carrots are the gold standard for flavour — sweet, crisp, and cylindrical with a smooth skin that barely needs peeling. They perform well in most UK soils but prefer light, stone-free ground to grow straight. If your soil is heavy clay, grow them in raised beds or deep containers filled with sandy compost. Sow thinly to avoid the need for heavy thinning, which attracts carrot fly. Cover rows with fine mesh or enviromesh as a physical barrier against carrot fly — this is far more reliable than companion planting alone. Successional sowing from March to July gives you carrots from June through to winter. Late sowings can be left in the ground over winter under a thick mulch of straw.
Butterhead Lettuce
Lactuca sativa
Butterhead lettuce produces soft, rounded heads with tender, buttery-textured leaves that melt in the mouth. It's one of the quickest salad crops to grow — ready in as little as 8 weeks from sowing. Unlike iceberg types, butterheads tolerate partial shade and are less likely to bolt in warm spells. Sow small batches every 2–3 weeks from March to September for a continuous supply. They work well as an intercrop between slower-growing vegetables like brassicas and leeks. Water consistently but avoid wetting the leaves to reduce the risk of grey mould. 'All the Year Round' is the classic UK variety and lives up to its name, performing well in almost every season.
