Blue elderberry attracts pollinators to improve fruit set.
Lavender repels pests that might harm blueberries.
Flowering herbs draw bees, hoverflies, and parasitic wasps — improving fruit set and biological pest control.
Strong aromatics like basil, garlic, and marigold mask the olfactory cues that pests use to find their target crop.
The top companions are Blue elderberry, Lavender. 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.
Plants in the same botanical family — often share cultivation needs and pest sensitivities.
