Companion Planting

Many companion-planting claims are traditional garden lore with limited scientific backing. Dill and other umbellifers genuinely attract beneficial insects (documented); aromatic herbs masking pest host-finding cues has some experimental support, but "improves flavor" claims are largely anecdotal.
