Start with spacing
Plant Chili Pepper at its recommended spacing (12" apart) first. Don't crowd it — healthy air circulation reduces disease.
Add herbs at the edges
Aromatic companions like Basil and Rosemary work well tucked 6–12" around the perimeter of the Chili Pepper planting.
Watch for height conflicts
Place taller companions (sunflowers, corn) on the north side of the bed so they don't shade Chili Pepper. 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.
