Step by step: plant pole Beans
Pole beans are frost-tender climbers that must be sown outdoors only after all risk of frost has passed, typically from mid-May through June in temperate Europe. Choose a site in full sun with well-drained loam or sandy soil. Before sowing, dig in a generous amount of well-rotted compost or manure to improve soil structure and moisture retention, but avoid excessive nitrogen, which encourages leafy growth at the expense of pods. Beans fix their own nitrogen, so soil needn't be overly rich. Sow seeds directly into the ground 3–4 cm deep and 30 cm apart. If you're growing beans up canes, wigwams, or netting, position seeds at the base of each support. For rows, erect sturdy poles or a trellis at least 2 metres tall before sowing; pole beans will quickly climb to 150–300 cm. You can also sow two or three seeds per station and thin to the strongest seedling once they've germinated, usually within 7–14 days depending on soil warmth. Water the drills gently after sowing to settle the soil, but avoid waterlogging. Germination is best when soil temperature is above 12°C. Once seedlings emerge, guide the young shoots gently around the supports in an anti-clockwise direction to encourage climbing. Mulch lightly around the base with compost or straw to conserve moisture and suppress weeds, but keep mulch clear of the stems to prevent rot. If late frosts threaten, cover young plants with fleece overnight.
