Although it isn’t essential, it’s possible you’ll even soak fava bean seeds for loads of hours to hurry up germination. That is notably useful if the native climate continues to be dry must you plant and likewise you may wish to be sure that the seeds germinate.

The leaves are susceptible to fungal rust, an airborne plant pathogen, so retaining them dry with good air circulation is essential.

Like completely completely different legumes, fava beans do not want nitrogen fertilizer (assuming your soil is midway first price—at most, it is doable you may amend with compost after you’ve pulled out final season’s crops).

They’ve the distinctive means to work with the rhizobia of their roots to make nitrogen from the air, and over-fertilization might very successfully stunt manufacturing of the pods.
