📐 How to Plant Pumpkin with Companions
Start with spacing
Plant Pumpkin at its recommended spacing (60" apart) first. Don't crowd it — healthy air circulation reduces disease.
Add herbs at the edges
Aromatic companions like Marigold and Nasturtium work well tucked 6–12" around the perimeter of the Pumpkin planting.
Watch for height conflicts
Place taller companions (sunflowers, corn) on the north side of the bed so they don't shade Pumpkin. Low-growing herbs and flowers can go anywhere in the bed.

Potato should be planted in a separate bed — ideally 3+ feet away — to prevent root exudate and pest crossover.
