Growing potatoes and garlic together is known as companion planting and it has several benefits:
1. Pest control: Garlic is a natural pest repellent and can keep pests away from the potato plants, reducing the need for pesticides.
2. Space utilization: Garlic is a low-growing plant, so it can be planted in between the potato plants to maximize space utilization.
3. Soil improvement: Both potatoes and garlic are heavy feeders, which means they require a lot of nutrients from the soil. However, they do not compete for the same nutrients. The garlic can improve the soil quality by adding nitrogen, while the potato plant's deep roots can help to loosen the soil.
4. Flavor enhancement: Garlic can enhance the flavor of the potatoes when they are harvested together.
Overall, growing potatoes and garlic together can result in healthier plants and a more productive harvest.
