Beetroot

Beta vulgaris

Beetroot is one of the most versatile and forgiving vegetables for UK growers. Each 'seed' is actually a cluster of seeds, so thin seedlings early to prevent overcrowding. 'Boltardy' is the go-to variety for early sowings as it resists bolting in cool conditions. For something different, try golden beetroot ('Burpee's Golden') or the stunning candy-striped 'Chioggia'. Beetroot is ready to harvest when the roots are golf-ball to tennis-ball size — don't let them get too large or they become woody. Both the roots and the young leaves are edible; baby beet leaves make an excellent addition to salads. Successional sowing from March to July provides a continuous supply. Beetroot stores well — twist off the leaves (don't cut, as this causes bleeding) and store in boxes of damp sand in a cool shed through winter.

Common Problems with Beetroot

Bolting

Beetroot bolts (runs to seed) when young plants experience a cold snap — typically when sown too early into cold soil before it has warmed to at least 7°C. Wait until mid-April for outdoor sowings, or use 'Boltardy', which is specifically bred to resist cold-triggered bolting. Covering early sowings with fleece helps maintain soil warmth.

Leaf miner

Pale, winding tunnels appear inside the leaves where larvae of the beet leaf miner fly are feeding between the upper and lower leaf surfaces. The damage is mostly cosmetic and rarely affects root development. Remove and destroy affected leaves to break the lifecycle, and cover plants with fine horticultural fleece to prevent the adult flies from laying eggs.

Woody roots

Beetroot left too long in the ground becomes tough, woody, and fibrous, with a coarse texture and dull flavour. Harvest at golf-ball to tennis-ball size for the best eating quality — don't be tempted to grow them bigger. Successional sowing every 3–4 weeks ensures a steady supply of tender young roots rather than a glut of overgrown ones.

Cherry Tomato

Solanum lycopersicum var. cerasiforme

vegetable

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

vegetable

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

vegetable

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

vegetable

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.
