Companion planting is an effective gardening method that enhances plant health, boosts yield, and naturally deters pests. Selecting the right pepper companion plants can lead to stronger growth, better flavor, and fewer plant diseases.
This guide highlights the best plants to grow alongside peppers, plants to avoid, and how to structure a garden for optimal results.
Best Companion Plants for Peppers
1. Basil 🌿
Basil helps keep pests like aphids, spider mites, and mosquitoes away from peppers while also enhancing their flavor.
2. Tomatoes 🍅
As members of the nightshade family, tomatoes and peppers share similar growing conditions. However, proper spacing is necessary to prevent competition for nutrients.
3. Onions and Garlic 🧄🧅
These pungent plants naturally repel aphids, beetles, and other insects that commonly attack peppers, making them excellent companion choices.
4. Marigolds 🌼
Marigolds help keep nematodes and harmful insects away while also attracting beneficial pollinators to the garden.
5. Carrots 🥕
Carrots and peppers make good companions since carrots grow deep in the soil while peppers have shallow roots, allowing both plants to thrive without competing for nutrients.
6. Spinach and Lettuce 🥬
Leafy greens like spinach and lettuce provide ground cover, which helps retain soil moisture and suppress weeds around pepper plants.
7. Beans and Peas 🌱
These legumes improve soil quality by adding nitrogen, an essential nutrient for healthy pepper growth.
8. Nasturtiums 🌸
Nasturtiums serve as a trap crop, drawing pests like aphids away from peppers while also attracting pollinators.
Plants to Avoid Growing Near Peppers
While some plants benefit peppers, others can hinder their growth:
🚫 Brassicas (Cabbage, Broccoli, Cauliflower, Kale) – These vegetables compete for nutrients and can slow down pepper development.
🚫 Fennel – Produces chemicals that may inhibit pepper growth.
🚫 Potatoes – Susceptible to similar pests and diseases as peppers, increasing the risk of infestation.
🚫 Corn – Attracts pests like aphids and armyworms, which may also target peppers.
🚫 Apricot Trees – Some varieties are prone to fungal infections that could spread to peppers.
How to Plan a Pepper Companion Garden
- Group plants with similar sunlight and water needs. Peppers thrive in full sun and well-draining soil, so selecting companions that require similar conditions is key.
- Use herbs and flowers for natural pest control. Basil, marigolds, and nasturtiums are excellent choices to reduce harmful insects.
- Incorporate taller plants for shade in hotter climates. Beans and corn can provide some relief from excessive heat.
- Rotate crops yearly. Moving peppers to a new location each season helps prevent soil depletion and disease buildup.
