Pole bean: Sowing, planting and harvest calendar
When and how do you sow climbing beans outdoors?
Sow climbing beans outdoors after the last frosts, once the soil has genuinely warmed. Late spring or early summer often suits temperate gardens, but adjust the start to your region. One mild day is not enough if the ground remains cold and wet: seeds may rot before emerging. Choose a climbing variety suited to the harvest you want, whether whole pods or shelled beans.
Prepare a sunny site sheltered from strong wind, with fertile soil that drains freely. Remove weeds and install the supports before sowing to avoid injuring roots later. Anchor canes or trellis securely: they must carry stems, foliage and the crop. Leave an access route so you can reach the plants without treading around their bases as they grow.
For common climbing French bean varieties, place one or two seeds about 5 cm deep at the base of each cane. Adjust the arrangement to your support and the variety's guidance. Cover and water gently if needed, without waterlogging the soil. After emergence, keep one strong plant at each point if both seeds have germinated. Check for slugs and monitor soil moisture. Guide the first twining shoots towards their support without tying them tightly.
How to care for this plant

Install plant supports
Install sturdy poles or a frame when sowing directly or planting out. Anchor them firmly before the beans climb. Guide young shoots towards the supports and check stability as they grow.
