Common Bean IntroductionCultivation InstructionsSeed Saving Instructions
Common beans are a diverse and important crop to Native American farmers throughout the Southwest. They are eaten young as green beans or dried and shelled. Plants can be bush, semi-pole, or pole.Beans need warm soil for best germination. Plant seeds in spring or with summer rains about 1" deep and 6" apart. If beans need a trellis, try intercropping with corn or sorghum.An annual that is generally self-pollinating, but can cross with other plants. Dried pods can be harvested throughout the growing season, or harvest whole plants. Separate varieties by 10 ft (3 m).
