10 Best Brussel Sprouts Companion Plants

Brussels sprouts, a member of the Brassicaceae family, benefit greatly from companion planting. This approach involves strategically positioning plants near each other to enhance growth, ward off pests, and improve flavors.

Selecting the right companion plants for Brussels sprouts can significantly contribute to a healthier and more productive garden.

Key Takeaways

1. Benefits of Good Companions

  • Flavor Enhancement: Certain companions like carrots and chamomile can improve the flavor of Brussels sprouts.
  • Pest Control: Plants like mint, basil, and garlic repel harmful pests, reducing the need for chemical pesticides.
  • Soil Improvement: Legumes such as peas and beans enrich the soil by fixing nitrogen.
  • Pollinator Attraction: Dill attracts bees, crucial for pollination and enhancing overall garden health.

2. Risks of Bad Companions

  • Nutrient Competition: Plants like eggplants and tomatoes can deplete essential nutrients, hindering the growth of Brussels sprouts.
  • Shade and Light Reduction: Tall or bushy plants like peppers may block sunlight, impacting Brussels sprouts’ development.
  • Pest Attraction: Certain plants, including potatoes and mustard greens, may attract pests that could harm Brussels sprouts.
