Aubergine
Solanum melongena
Aubergines can be grown successfully in the UK, though they need warmth and a long season. These glossy, purple-skinned fruits are a staple of Mediterranean and Asian cooking, and home-grown specimens have a far superior flavour and texture to shop-bought. Sow seeds in late February or March on a heated propagator at 25°C — they need high temperatures to germinate. Grow on in a greenhouse or polytunnel for the best results, though modern compact varieties can crop on a sunny, sheltered patio. Pot into 25cm containers or grow bags, two per bag. Pinch out the growing tip when the plant reaches 30cm to encourage branching. Allow 5–6 fruits per plant — remove additional flowers to concentrate the plant's energy. Feed weekly with high-potash tomato fertiliser once the first fruits set. Harvest from August when the fruits are glossy and firm — dull, matt skin indicates the fruit is over-mature and will be seedy and bitter. 'Moneymaker' and 'Black Beauty' are traditional varieties; 'Slim Jim' and 'Pinstripe' produce smaller, more prolific fruits ideal for containers. In a good summer, outdoor aubergines in southern England can be very productive.

Time to Harvest Aubergine
Expect to harvest approximately 5 months after sowing.
Companion Plants
Expected Yield
5–6 fruits per plant in a greenhouse; fewer outdoors. Each fruit weighs 200–400g.
Growing Tips
Best in greenhouse; limit to 5–6 fruits per plant
Common Problems with Aubergine
Red spider mite
Tiny mites cause fine speckling on leaves, which turn bronze and dry; fine webbing visible in severe infestations. Thrives in hot, dry greenhouse conditions. Mist plants regularly to raise humidity, and introduce the biological control Phytoseiulus persimilis early in the season. Remove and destroy badly affected leaves.
Whitefly
Clouds of tiny white flies rise when the plant is disturbed, weakening the plant and depositing sticky honeydew. Use yellow sticky traps for monitoring and mass trapping. Introduce the parasitic wasp Encarsia formosa in the greenhouse from April. Spray with organic neem oil for heavy infestations.
Poor fruit set in cool summers
Aubergines need consistently warm conditions (20°C+) to set fruit. In cool UK summers, flowers may drop without producing fruit. Grow in a greenhouse or polytunnel for reliable results. Tap flower trusses gently to aid pollination. Misting flowers can also help. Choose early-maturing, compact varieties for outdoor growing.

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.
