Good Companions for Rutabaga
OnionAllium cepa
BeneficialPest SuppressionSupported
Onion volatile-mediated pest suppression of cabbage root fly (Delia radicum), the primary pest of rutabaga roots. Rutabaga's long growing season (90+ days) benefits from sustained allium protection.
Plant onion sets among rutabaga rows. Rutabaga needs more time than turnip, so companion protection is more valuable.
