FAQ
Q: Can I use eggshells for all plants?
A: Most plants benefit from calcium, but avoid using large amounts on acid-loving plants like blueberries or azaleas, as it can raise soil pH.
Q: How often should I use eggshells?
A: A light sprinkle every few weeks is usually enough. Crushed shells can remain in soil for several months, slowly releasing nutrients.
Q: Do eggshells actually prevent pests?
A: They can deter soft-bodied pests like slugs and snails when used around plants, but they aren’t a complete pest solution.
