For those living in rural areas, eggshells can even help keep deer away. Deer reportedly dislike the smell of eggs, so spreading broken shells around your garden can discourage them from wandering too close to your plants.
10. Use Eggshells as Seed Starters
Eggshells make great biodegradable seed pots. Simply rinse out the shells, fill them with a bit of soil, and plant your seeds inside. Keep them in an egg carton by a sunny window until the seedlings sprout. When it’s time to transplant them, place the entire shell directly into the ground — it will naturally decompose, enriching the soil and providing extra calcium for your growing plants.

12. Balance the Soil’s pH Levels
The pH level of your soil plays a big role in how your plants grow — and even what color some flowers turn out to be. Hydrangeas, for instance, can turn pink or blue depending on the soil’s acidity. If your soil is too acidic, adding crushed eggshells can help balance the pH and create a more neutral environment for your plants.
13. Add Eggshells to Your Compost
Finally, eggshells are an excellent addition to your compost pile. When crushed, they break down faster and add valuable calcium and minerals to your compost mix, enriching the final product. Remember to crush them first so they decompose efficiently.
