Try Runner Beans For Bumper Crops

Runner beans growing

by Garden News |

Runner beans are one of the most rewarding and productive crops you can grow, and take up little soil space.

Planted now under glass you'll get sizeable plants to plant out from late May, after the threat of late frost has passed, producing earlier crops than if sown directly, which you can do from mid-May till July.

Recent breeding has focused on durability, improving performance, an ability to self-pollinate, and heightened resistance to rust and leaf spot diseases.

As well as productive, runner beans are decorative, with flowers from scarlet through shell-pink to white, to bi-coloured.

Sow the seeds individually in cells or 7.5cm (2¾in) pots. They'll germinate at over 12C (54F). When they're big enough to handle, pot on seedlings into larger containers. Harden off before planting outdoors on a frame of canes or sweet pea net. If sowing outdoors, plant two seeds per station 30cm (1ft) apart, thinning to one plant.

Beans need a sheltered, warm site with a rich, light soil, plenty of moisture and feeding.

Self-fertile varieties will help pods form, but shaking the plants will ensure this by dislodging pollen. Keep plants moist, particularly when pods are forming, and harvest regularly to ensure more flowers and pods form.
