Horseradish
Armoracia rusticana
Horseradish is a hardy perennial root crop with a fierce, pungent flavour — the essential ingredient in homemade horseradish sauce for roast beef. It's incredibly easy to grow, almost to a fault: it spreads readily from any piece of root left in the soil, so contain it in a deep pot, an old dustbin, or a dedicated corner of the plot you don't mind giving over to it permanently. Plant root cuttings (thongs) in March, 30cm deep with the top just below soil level. The first season focuses on leaf growth; harvest substantial roots from autumn of year two onwards. Lift roots as needed from October to February — flavour is strongest after the first frosts. Grate fresh for the best heat; flavour fades within minutes of grating.

Companion Plants
Expected Yield
Established plants yield 1–2kg of roots per crown per year.
Common Problems with Horseradish
Spreading invasively
Any root fragment regrows. Grow in a buried dustbin or large container with the bottom removed, or commit to a permanent corner of the plot. Dig the whole patch annually to control spread.
Forked or stunted roots
Caused by stony, compacted soil. Dig deeply before planting and remove stones. Grow in raised beds or large containers for clean, straight roots.
Loss of flavour after grating
Volatile oils dissipate within 30 minutes of grating. Always grate fresh and use immediately, or preserve by mixing with vinegar straight after grating.

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.
