Once you’ve enjoyed your morning eggs, don’t waste the eggshells – they're the perfect addition to your garden. A great composting option, they also deter garden pests like slugs. Plus, chicken egg shells are comprised of about 96% calcium carbonate, which is an essential plant nutrient and moderates soil acidity.
"Fast-growing plants deplete the soil of calcium very quickly, so egg shells are an ideal supplement and feed for outdoor flowers, vegetables and fruit trees in your garden," says Gardenesque. Simply rinse them, crush them and spread them around the base of your plants for a multitude of benefits.
