2. Use Crushed Eggshells Around Garden Plants
Eggshells are often used in home gardening because of their calcium content.
Crushed shells can be mixed into garden soil, where they gradually break down.
Calcium is an essential plant nutrient and plays an important role in plant structure and growth.
However, there’s an important caveat:
Eggshells aren’t a quick fertilizer.
Their calcium isn’t immediately available to plants because the shells break down slowly.
If your soil genuinely has a calcium deficiency, a soil test and an appropriate soil amendment are usually much more reliable than simply throwing eggshells around your plants.
Still, crushed eggshells can be a useful addition to a broader composting and gardening routine.
