📐 How to Plant Eggplant with Companions
Start with spacing
Plant Eggplant at its recommended spacing (24" apart) first. Don't crowd it — healthy air circulation reduces disease.
Add herbs at the edges
Aromatic companions like Thyme work well tucked 6–12" around the perimeter of the Eggplant planting.
Watch for height conflicts
Place taller companions (sunflowers, corn) on the north side of the bed so they don't shade Eggplant. Low-growing herbs and flowers can go anywhere in the bed.
Keep incompatible plants a bed away
Fennel should be planted in a separate bed — ideally 3+ feet away — to prevent root exudate and pest crossover.
