How to Plant Rosemary with Companions
Start with spacing
Plant Rosemary at its recommended spacing (24" apart) first. Don't crowd it — healthy air circulation reduces disease.
Add herbs at the edges
Aromatic companions like Sage work well tucked 6–12" around the perimeter of the Rosemary planting.
Watch for height conflicts
Place taller companions (sunflowers, corn) on the north side of the bed so they don't shade Rosemary. Low-growing herbs and flowers can go anywhere in the bed.
Keep incompatible plants a bed away
Even without known incompatible plants, rotate Rosemary to a new bed each season to prevent soil depletion.
