Eggs are delicious and nutritious. Most people throw away the shells, which is the best part—for plants at least. Instead of throwing away this resource, consider using it to improve the soil in your garden, as eggshells are a good source of calcium for your plants, and can help make a great fertilizer. You can easily add minerals and nutrients to soil using crushed eggshells or eggshell tea. You can also use eggshells as seed starters to ensure that your seedlings get off to a good start.
