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.
5. Compost additive
Eggshells are an ideal addition to your compost pile. Their calcium content balances the acidity of many kitchen wastes, contributing to a more neutral pH in the compost. The calcium also supports decomposition and enriches the resulting compost with valuable nutrients.
