Start with spacing
Plant Tarragon at its recommended spacing (12" apart) first. Don't crowd it — healthy air circulation reduces disease.
Add herbs at the edges
Aromatic companions like Eggplant work well tucked 6–12" around the perimeter of the Tarragon planting.
Watch for height conflicts
Place taller companions (sunflowers, corn) on the north side of the bed so they don't shade Tarragon. Low-growing herbs and flowers can go anywhere in the bed.
Keep incompatible plants a bed away
Even without known incompatible plants, rotate Tarragon to a new bed each season to prevent soil depletion.
