Sugar Snap Pea
Pisum sativum var. macrocarpon
Sugar snap peas combine the sweetness of mangetout with the plump pods of garden peas — eat the whole thing, pod and all. They're one of the most rewarding crops for kids and a brilliant early-season cropper on allotments. Sow direct from March to June in double rows 30cm apart, with twiggy pea sticks or netting for support. Most varieties reach 1.5m, though dwarf types like 'Sugar Ann' need only 60cm. Pick pods when plump but before the seeds harden inside — daily picking keeps plants productive for 4–6 weeks. Mice love pea seeds, so sow into modules under cover and transplant if mice are a problem. Mildew often strikes in late summer, so consider an autumn sowing of resistant varieties for a second crop.

When to Sow Sugar Snap Pea
Sow sugar snap pea in March, April, May, June.
Time to Harvest Sugar Snap Pea
Expect to harvest approximately 3 months after sowing.
Expected Yield
A 3m double row yields around 3–4kg of pods over 4–6 weeks.
Common Problems with Sugar Snap Pea
Powdery mildew
White powdery coating on leaves in dry summers. Water at the base, mulch to retain soil moisture, and choose resistant varieties like 'Sugar Ann'. Autumn sowings often escape mildew entirely.
Mice eating seeds
Mice can clear a whole row overnight. Start seeds in modules under cover and transplant once 10cm tall. Lay holly cuttings or prickly material over direct sowings as a deterrent.
Pea moth maggots in pods
Tiny caterpillars inside pods from eggs laid during flowering. Cover plants with fine mesh during flowering, or sow very early (March) or late (June) to avoid the egg-laying window.

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.
