All about growing French Beans from seed
Growing Guide
French Beans give you two crops for the price of one: enjoy the pods when they're young and tender, or leave them to dry on the plant for use as haricot beans. Easy to grow and heavy cropping. A tender crop, wait until at least April to begin sowing these. Choose either dwarf or climing varieites to suit your growing space.
Sow seeds indoors from mid April for transplanting later on, or direct sow outdoors from late May to July.
Indoors, sow bean seeds at a depth of 4cm in 7.5cm pots or trays of free-draining, seed sowing compost. Place in a propagator or seal container inside a plastic bag until germination. Do not exclude light as this helps germination, and keep pots moist. Once germinated, grow on in cooler conditions until all risk of frost has passed and the plants are large enough to be transplanted.
Gradually acclimatise them to outdoor conditions over 7 - 10 days before planting French beans outdoors in rich fertile, well drained soil in full sun with protection from strong winds.
When growing beans, hoe between plants often and water regularly. Provide a compost mulch around the base of bean plants to combat dry periods.

Top Tip
Don’t be tempted to plant out your beans until the risk of frost is over. The shock of lower temperatures could kill them. Harden off your plants by putting them outside for a short time each day and bringing them in each night until they’ve acclimatised.
Picking the beans stimulates your plants to produce more and gives you a
longer harvest period. Although some bean varieties stay tender as they
grow, others become more tough and stringy. Beans are best picked when
they are still small and tender.
Climbing beans need something to cling to as they grow and everyone has their own preferred support method, whether that’s a few sticks in a container, a wigwam made of canes or something more purpose made. Whatever you do be sure to give them the support they need, or perhaps try trailing them from a windowbox for something a bit different.
