  • Brassicas (kale, cabbage, and broccoli) should not be planted near peppers as they release compounds that can inhibit pepper growth.
  • Fennel negatively affects pepper growth and flavor due to the chemicals it produces.
  • Apricot trees release a chemical called allelopathy that can inhibit the growth of pepper plants.

When it comes to planting a successful pepper garden, choosing the right companion plants can make a big difference. Companion planting involves strategically planting different species together to enhance growth, repel pests, and improve overall garden health. While some plants thrive alongside peppers, there are certain plants that should be avoided due to their negative effects on pepper growth. In this article, we will explore the plants that should not be planted next to peppers, based on information from various reliable sources.

Brassicas – Kale, Cabbage, and Broccoli

According to Martha Stewart, one plant group to avoid planting near peppers is Brassicas, which includes kale, cabbage, and broccoli. Brassicas are known to release compounds that can inhibit pepper growth. These plants belong to the same family as peppers, the nightshade family (Solanaceae), and can compete for nutrients and space in the garden.


Fennel is another plant that should not be planted near peppers. According to The Spruce, fennel can negatively affect pepper growth and flavor. Fennel produces chemicals that can hinder the growth of neighboring plants, including peppers. It is best to keep fennel away from your pepper plants to ensure their optimal growth.

Apricot Trees

If you have apricot trees in your garden, it is advisable to avoid planting peppers nearby. According to The Spruce, apricot trees release a chemical called allelopathy, which can inhibit the growth of pepper plants. These chemicals are released through the roots, leaves, and fallen fruit of the apricot tree, creating an unfavorable environment for peppers.


Beans are not recommended to be planted next to peppers. According to The Spruce, beans and peppers have different nutritional requirements, and planting them together can result in competition for nutrients. Additionally, beans can also cast shade on pepper plants, which may negatively impact their growth.


In summary, it is best to avoid planting peppers next to brassicas like kale, cabbage, and broccoli, as well as fennel, apricot trees, and beans. These plants can either inhibit pepper growth, compete for resources, or create unfavorable conditions that can hinder the health and productivity of your pepper plants.
