How can I effectively repurpose peanut shells in my garden to improve soil quality and promote plant growth?

To effectively repurpose peanut shells in your garden, you can crush them into small pieces and mix them into the soil. Peanut shells are rich in nutrients like nitrogen and potassium, which can help improve soil quality and promote plant growth. Over time, the shells will decompose, releasing these nutrients into the soil. This can enhance soil fertility and provide a sustainable way to recycle peanut shells in your garden.
