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