Tomatillo

Physalis ixocarpa

Tomatillos are the tangy green fruits inside papery husks that form the base of Mexican salsa verde. They grow like sprawling tomato plants but are more vigorous and disease-resistant, making them surprisingly easy in the UK climate. Critically, you must grow at least two plants — tomatillos are self-incompatible and won't set fruit without cross-pollination. Sow seeds in March under cover, plant out after last frost, and stake or cage like tomatoes (plants reach 1.2m and sprawl widely). Fruits are ready when they fill the husk and the husk splits — usually August to October. Pick before the husk turns fully brown; over-ripe fruits go yellow and lose their tang. Use immediately or refrigerate in their husks for up to a month.

Time to Harvest Tomatillo

Expect to harvest approximately 4 months after sowing.

Companion Plants

Expected Yield

Each plant yields 1.5–2.5kg of fruit — two plants make plenty of salsa for a season.

Common Problems with Tomatillo

No fruit setting

Tomatillos are self-incompatible — a single plant rarely fruits. Always grow at least two plants close together to ensure pollination.

Plants sprawling everywhere

Tomatillos grow far more vigorously than tomatoes. Cage with a sturdy frame at planting or grow against a strong stake — once they sprawl they're hard to tame.

Sticky residue on fruit

The husk and skin produce a sticky natural coating. Rinse fruits in warm water after husking to remove it — perfectly harmless and washes off easily.

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.
