Worst Companion Plants for Garlic

  • Asparagus – Asparagus and garlic aren’t great companion plants and should be planted at a great distance away from each other. Allium plants, including garlic, tend to stunt the growth of asparagus.
  • Beans – Garlic can affect beans negatively when planted close together. It is best to plant beans away to prevent garlic from stunting their growth.
  • Peas – Make sure to keep peas away from your garlic because these two plants don’t do too well together. Since peas have short roots, garlic may inhibit the growth of their roots.
  • Parsley – Parsley is another plant that cannot achieve its full glory when planted near garlic or other allium plants. Its development will be stunted, so it’s better to plant this at a reasonable distance.
  • Sage – Alliums, including garlic, prefer growing in rich, slightly moist, and well-draining soil, while sage thrives in a dry and sandy environment. These two don’t grow in the same conditions, so it’s better to plant them apart.
