How to grow field beans
Sow field beans 2cm deep and 10cm apart, in rows 15cm apart. Field beans will establish quickly. They are excellent nitrogen fixers, but make sure you cut them down before they start growing actual beans, as this takes the nitrogen away.
If you are following a crop rotation system, field beans should be grown in the same area as other legume plants.
Incorporating field beans into your soil
Cut down or hoe off the leaves of your field beans before digging in the whole plants four weeks before the soil is needed for your next crop and before flowering, which happens when the plants are about 30-45cm tall.
