📐 How to Plant Snapdragon with Companions
Start with spacing
Plant Snapdragon at its recommended spacing (12" 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 Snapdragon planting.
Watch for height conflicts
Place taller companions (sunflowers, corn) on the north side of the bed so they don't shade Snapdragon. Low-growing herbs and flowers can go anywhere in the bed.
Keep incompatible plants a bed away
Even without known incompatible plants, rotate Snapdragon to a new bed each season to prevent soil depletion.
