Brussels Sprouts Companion Plants

Brussels sprouts are heavy-feeding, long-season cole crops that share pests like cabbage worms, aphids, and flea beetles with the rest of the cabbage family. Traditional companion planting pairs them with strong-scented herbs and alliums to confuse those pests, low-growing greens to shade the soil, and flowers that pull in pollinators and beneficial insects. Growers pick companions to muddy pest cues and make better use of the space between the tall, slow-growing plants.

BeetsThey grow at a different depth, so they share space without much competition.

Keep Brussels Sprouts away from

PlantWhy to separate them
Other brassicas (cabbage, broccoli, kale)Planting cole crops together concentrates shared pests and diseases in one spot.
TomatoesBoth are heavy feeders that compete hard for soil nutrients and space.
StrawberriesA traditional pairing to avoid, as they are said to hold back cabbage-family growth.
Peppers and eggplantThese nightshades are hungry feeders and offer little pest benefit in return.
Pole beansTall climbers can crowd and shade the already large, slow-maturing sprouts.

Tips

Give sprouts steady, rich soil and plenty of room, then tuck fast greens and low herbs around their base while the stalks fill in. Interplant alliums and aromatic herbs through the bed rather than in one row so their scent is spread across the crop. Companion planting is a traditional practice and results vary by garden, so treat these pairings as a starting point and keep watching your own plants.
