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