Benefits of Planting Together

Planting potatoes, chives, and cosmos together offers several advantages. Chives help repel aphids and Japanese beetles, common pests for potatoes, while enhancing their flavor. Cosmos attract beneficial insects like bees and butterflies, promoting pollination and biodiversity. The combination of these plants also maximizes space and improves soil health by diversifying root structures and nutrient uptake.
