Make your soil mineral rich

Eggshells are not just rich in calcium but have a good amount of magnesium and minerals too. Adding them to the soil will enhance its mineral content and ensure a healthy growth of plants.

Deter cats

If you find cats frequenting your garden to litter, all you need to do is spread some crushed egg shells around the area they usually trod and after stepping on them for a few times, they will understand the danger of sharp shells and won’t return.
