Most people throw away eggshells but don’t realize how important they are!

3. Sow starter pots

Eggshells make excellent biodegradable seed pots. Fill each half-shell with potting soil, sow your seeds and place them in an egg carton for stability. When it’s time to transplant, simply crush the eggshell and plant the whole thing in the garden. The eggshell decomposes and provides the young plant with nutrients.

4. Soil improvement

In addition to calcium, eggshells contain small amounts of other essential minerals such as magnesium and potassium. When eggshells are crushed and mixed into the soil, they improve its structure and provide your plants with these vital nutrients. Over time, this can lead to healthier and more productive gardens.
