For years I automatically crumbled and added eggshells to the compost, but not lately. Those eggshells pack some powerful garden nutrients, in particular calcium. Don’t waste them in the compost, instead dry the shells and then crumble them right into the garden where they will have the greatest impact.

Roses and a lot of other shrubs, perennials and annuals thrive on eggshells. Those plants that prefer an alkaline environment benefit from frequent additions of crumbled eggshells. I also like to scatter the shells around many herbs, lavender, rosemary, basil and others. And for plants plagued by slugs, a layer of crumbled eggshells can help prevent visits of those slimy pests. And, of course, you can still add eggshells to the compost mix too.
