Recent research suggests that evening watering of the roots increases pod set and subsequent cropping. Sow under cover in April for early crops, planting out in late May. For early crops sown outdoors, protect with fleece or cloches to warm the soil and protect the young plants. Sow outside 5–7.5cm (2–3") deep, spacing seeds 15cm (6") apart in double rows 45cm (18") apart. Allow a further 1.5m (5') between double rows. (Alternatively if space is limited, sow in circles and grow up canes in a ‘wigwam’ format.) Insert long cane supports or netting soon after germination/planting. Plants will reach a height of 1.8–2.1m (6–7').
