Good Companions for Eggplant

Bush BeanPhaseolus vulgaris
BeneficialNutrient SharingSupported

Bush beans fix atmospheric nitrogen via Rhizobium symbiosis, increasing soil available N for the heavy-feeding eggplant. Bean foliage also acts as living mulch, suppressing weeds and moderating soil temperature.

Plant bush beans between eggplant rows. Both prefer warm soil and full sun.
