NasturtiumTropaeolum majusacts as a trap crop
Nasturtium can draw aphids away from young raspberry growth.
What to plant with Red raspberry
Rubus idaeus
Red raspberry grows best when paired with plants that acts as a trap crop, repels pests, attracts pollinators. We've catalogued 9 beneficial companions and 1 antagonist to avoid. Every pairing below cites its mechanism — pest deterrence, nitrogen fixing, allelopathy, or shared disease.

Management warning: fennel is traditionally grown apart because it can inhibit neighbouring crops and disrupt guild balance.
IV
How these mechanisms work
trap crop
A sacrificial crop draws pests away from the main harvest.
pest repellent
Strong aromatics like basil, garlic, and marigold mask the olfactory cues that pests use to find their target crop.
pollinator attractor
Flowering herbs draw bees, hoverflies, and parasitic wasps — improving fruit set and biological pest control.

Frequently asked
What are the best companion plants for Red raspberry?
The top companions are Nasturtium, Tansy, Bergamot. 6 more pairings are catalogued above with their mechanisms.
What should I NOT plant near Red raspberry?
Avoid Fennel. Reasons vary — allelopathy, shared pests, or resource competition. See the section above for each plant's specific issue.
Can companion planting reduce pest damage on Red raspberry?
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.
Is companion planting scientifically proven?
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.
