It is best to start the beans in small pots, and sow two beans per pot 5cm (2in) deep (only plant the strongest plant). Place the pots outside in a coldframe, or in a sheltered position. Once the beans reach 8cm (3in) tall you can plant them out into their final positions, this will be about June or July.
