Good Companions for Turnip
Snap PeaPisum sativum var. macrocarpon
BeneficialNutrient SharingSupported
Pea nitrogen fixation benefits turnip growth. Both are cool-season crops. Pea vines provide light shade that moderates soil temperature for turnip root development.
Sow together in early spring. Harvest turnip greens while peas establish, then harvest turnip roots.

OnionAllium cepa
BeneficialPest SuppressionSupported
Onion volatiles deter flea beetles and cabbage root fly on turnip. Both occupy different root zones, reducing below-ground competition.
Interplant in alternating rows for best volatile coverage.
