Scientific name: Geranium
Benefits: Attracting pests such as Japanese beetles and cabbage worms away from peppers.

Geraniums are a perfect choice if you’re looking for a plant that will protect your peppers from pests. They act as a diversion plant that will attract pests instead of letting them attack your pepper plant. The pests they attract are Japanese beetles and cabbage worms. While they are excellent at attracting destructive insects that may harm your pepper plant, they are not pollinator-friendly. If you are looking to attract more pollinators in your garden, it would be wise to plant some flowering plants that appeal to bees.

Before choosing companion plants for your peppers, it is vital to research which plants can benefit them and which may have harmful effects. While many companion plants work as an excellent addition to pepper plants, certain plants can only negatively affect peppers’ growth. These plants may share the same predators or attract potential diseases and fungi or tend to take up all the nutrients, preventing peppers from thriving.

  • Peas: Add nitrogen to the soil, preventing peppers’ healthy growth.
  • Cabbage: Takes up most of the nutrients from the soil.
  • Corn: Takes most of the sunlight away from peppers.
  • Beans: Takes up most nutrients and add nitrogen to the soil.
  • Sunflowers: Takes away most of the sunlight, leaving peppers in the shade.
  • Cauliflower: Depletes the soil of essential nutrients.
  • Fennel: Attracts many harmful pests.
