Scorzonera
Scorzonera hispanica
Often called black salsify, scorzonera produces long, slender black-skinned roots with sweet white flesh and a subtle nutty flavour. Treat it much like salsify: sow direct in April or May into deep, well-worked soil, thin to 10cm, and leave alone through summer. Roots reach pencil thickness by autumn but are best lifted from late October onwards — flavour improves after frost. Fully hardy, so leave in the ground and harvest as required through winter. The yellow daisy-like flowers attract hoverflies in the second year if you leave a few roots, and unopened flower shoots are delicious cooked like sprouting broccoli. A genuine gourmet crop with almost no pest problems.

When to Sow Scorzonera
Sow scorzonera in April, May.
Time to Harvest Scorzonera
Expect to harvest approximately 6 months after sowing.
Companion Plants
Expected Yield
Expect around 3kg of roots from a 3m row.
Common Problems with Scorzonera
Brittle roots snap when lifting
Roots can reach 30cm deep. Loosen the full depth with a fork well alongside the row before easing each root out — never pull from the top.
Slow to germinate
Seed loses viability quickly. Always use fresh seed (current year), sow into warm moist soil and don't let the surface dry before emergence.
Black skin staining hands
The sap is harmless but stains. Wear gloves and peel under water, or boil whole then rub off skins after cooling.

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.
