You can plant a variety of companion plants with peppers to improve growth, deter pests, and make efficient use of garden space. Here are some of the best options:

Herbs

• Basil: Enhances pepper flavor and repels aphids, spider mites, and thrips

• Cilantro, Parsley, Rosemary, Thyme, Dill, Chamomile: Attract pollinators and beneficial insects, improve soil health, and help protect peppers from disease

• Garlic and Onions: Their pungent oils repel aphids and other pests

Vegetables and Greens

• Bush Beans and Pole Beans: Improve soil nitrogen and grow well near peppers

• Carrots: Loosen soil for better pepper root growth and attract beneficial insects

• Leafy Greens (Arugula, Mizuna, Mustard Greens, Lettuce, Spinach, Swiss Chard, Kale): Provide ground cover, shade soil, retain moisture, and suppress weeds without shading peppers

• Marigolds and Nasturtiums: Help keep pests away and attract pollinators

Other Fruiting Plants

• Tomatoes and Eggplants: Can be grown near peppers as they share similar growing conditions, but watch for shade and disease overlap

Additional Tips

• Avoid planting heavy nutrient feeders like cabbage too close unless soil is well-fertilized

• Use low-growing plants around peppers to avoid blocking sunlight.
• Companion plants can help maintain soil moisture and reduce weeds.

In summary, ideal companions for peppers include herbs like basil, cilantro, and thyme; vegetables such as carrots, beans, and leafy greens; and flowers like marigolds to deter pests and attract pollinators
