Benefits of Planting Together

Planting peppers, beans, and sunflowers together offers several benefits:

• Pest Repellent Properties: Sunflowers can attract pests such as aphids, diverting them from peppers and beans.
• Improved Growth: Beans enhance soil fertility by fixing nitrogen, which can improve the growth of peppers and sunflowers.
