Cabbage Companion Plants

Cabbage is a heavy-feeding brassica that draws its share of pests, so gardeners have long paired it with strong-scented herbs, flowers, and alliums meant to mask its smell, pull pests away, or invite the beneficial insects that keep those pests in check. Low, leafy companions can also share space and shade the soil while the heads size up. Companion planting is a traditional practice rather than a guaranteed method, so treat these pairings as a helpful starting point and expect results to vary with your climate, soil, and pest pressure.

Keep Cabbage away from

PlantWhy to separate them
Other brassicas (broccoli, cauliflower, kale)They share the same pests, diseases, and heavy nutrient needs, which concentrates problems.
TomatoesBoth are hungry feeders that compete for nutrients and room.
StrawberriesA long-standing pairing to avoid, as the two are said to grow poorly together.
Pole beansTheir sprawling vines can crowd and shade cabbage as it tries to head up.
GrapesTraditional guidance holds that cabbage planted close by can set back grapevines.

Tips

Give cabbage rich, steady soil and space each plant well so air moves freely and heads have room to fill out. Tuck aromatic herbs and alliums along the edges and between plants, and add a few flowering companions to pull in helpful insects while you scout for eggs and worms by hand. Rotate cabbage and its brassica relatives to a fresh bed each year, since planting them in the same spot invites a buildup of shared pests and soil diseases.
