Good Companions for Kohlrabi

OnionAllium cepa
BeneficialPest SuppressionSupported

Onion volatiles mask kohlrabi host-plant cues from cabbage root fly and flea beetles. Onion and kohlrabi occupy different root zones, reducing competition.

Interplant in alternating rows. Both are cool-season crops with similar cultural needs.

LettuceLactuca sativa
BeneficialPhysical SupportSupported

Lettuce intercropped with kohlrabi provides ground cover that conserves moisture and suppresses weeds. Different growth habits and root depths reduce competition. Efficient use of bed space.

Plant lettuce between kohlrabi. Harvest lettuce as kohlrabi bulbs expand.
