Start with spacing
Plant Edamame at its recommended spacing (6" apart) first. Don't crowd it — healthy air circulation reduces disease.
Add herbs at the edges
Aromatic companions like Corn work well tucked 6–12" around the perimeter of the Edamame planting.

Place taller companions (sunflowers, corn) on the north side of the bed so they don't shade Edamame. Low-growing herbs and flowers can go anywhere in the bed.
