Tansy is used in traditional orchards to deter ants and some flying pests.
Tansy is traditionally used at berry patch edges; keep it managed.
Strong aromatics like basil, garlic, and marigold mask the olfactory cues that pests use to find their target crop.
The top companions are Apple, Red raspberry. See above for the full list with mechanisms.
Aromatic companions deter many pests through scent masking and alarm pheromones. Effect varies by pest species and density — most effective as part of a polyculture, not a one-plant solution.
Some mechanisms are well-documented (legume nitrogen fixation, allelopathy in walnut and fennel, nematode suppression by marigolds). Others are traditional pairings with anecdotal support. We cite both, but mark mechanism strength where available.
