Why broad bean pods are empty.

Posted Jun 04 2009 10:01pm

Why are some mature broad bean pods empty, with immature, undeveloped beans?

  • Broad beans need the right day-length and a temperature of about 20°C at flowering. If the beans are planted too early in the spring, & there is a blip in the weather as the first beans flowered, the beans will not set well.
  • Crops planted too late will also produce low yields and will be affected by high temperatures later in the season.
  • Broad beans produce less well in windy areas. Double rows (20 cm apart) help the plants to withstand wind. Otherwise a windbreak pays dividends.


Broad bean pods tend to be empty at the start of the season, before the conditions are right for the beans to set.
