The end of February or beginning of March is a good time to sow broad beans.
They can be sown directly into the ground, but will need the protection of a cloche early in the season.
Alternatively they can be sown into deep pots in a polytunnel, greenhouse or cold frame and planted into the garden in April or early May.
Sow the seeds 5 cm deep and 23 cm apart.
Mice and birds like the seeds and young shoots so try to discourage them with nets.
Broad bean plants have a tendency to flop over so it is a good idea to support them with canes and string (see photo).
