The best location to grow broad beans

Sunlight

The rule of thumb is that all flowering and fruiting plants need full sun exposure. That means they need more than six hours of direct light. Fava beans, however, will grow almost everywhere.

Provide a minimum of four hours of direct sun, and your broad beans will be fine. They may grow at a slower pace, but they will still produce. They may also grow skinnier stems, which will require extra support.

Soil

In general, there are no special requirements for soil for growing legumes. It just needs to be well-draining to prevent seed and root rot. Legumes are nitrogen fixers, which means they make their own Nitrogen to grow. For this reason, they are also grown as a ground cover to give the soil some rest.

Water

Being a cool-season crops, broad beans will survive on rain water unless drought is in effect. Constant moisture eliminates stress and the plants will grow healthier and stronger. Provide supplemental water before the soil goes bone-dry.

Do broad bean plants fix nitrogen in the soil?

Legumes have a symbiotic relationship with certain soil bacteria. The Rhizobia bacteria invade the legumes’ roots and feed on the nutrients and energy provided. In return, this bacteria fixes the nitrogen found in the air for the plant to use.

The multiplication of bacteria causes nodules to form on the roots; this is where Nitrogen is stored. Legumes use this Nitrogen during their growth. Extra Nitrogen is released only when the plants are dead and turned into the soil.

The only way for the soil to benefit from Nitrogen leftover from legume plants is by leaving their roots in the ground at the end of the season. Either chop down the plants and turn them into the soil or cut them at the base.
