Five Ways to Use Eggshells in Your Garden

A normal person looks at an egg and thinks “omelet” or “frittata.” A gardener (especially one who tends to be on the obsessive end of the spectrum) looks at an egg and thinks “yes! Eggshells!”

Five Ways to Use Eggshells in Your Garden

1. Add crushed eggshells to the bottom of planting holes, especially for tomatoes, peppers, and eggplant. These crops are susceptible to blossom end rot, which is caused by calcium deficiency. While this deficiency is most often caused by improper watering, there’s no harm in making sure your plants have a steady source of calcium. As the eggshells break down, they’ll nourish the soil, and your plants.

2. Use eggshells as pots for starting plants from seed. Then plant the seedling, “pot” and all, into the garden.

3. Use crushed eggshells to deter slugs, snails, and cutworms. These garden pests are a real pain in the gardener’s neck, and cutworms are the worst, killing seedlings by severing the stems at soil level. All three of these pests have soft undersides, and dislike slithering across anything sharp. Crushed eggshells, applied to the soil’s surface, may help deter these pests.

4. Add them to the compost pile. If you aren’t planting tomatoes or trying to deter slugs, add the eggshells to your compost pile, where they’ll add calcium to your finished compost.

5. If you are feeding birds in your yard, crush up the eggshells and add them to a dish near the feeder. Female birds, particularly those who are getting ready to lay eggs or recently finished laying, require extra calcium and will definitely appreciate it!

No matter how you want to use them, be sure to rinse the shells out well before using them in the garden.

Happy blogging!

    This sounds easy. I don’t have a green thumb, but I do eat a lot of eggs. I will try this and come back with my results.

    I have done this. I would add that you should not only rinse the shells, but lay them out on the counter or somewhere where they can dry completely, so they do not develop any mold!
    Then, crush them in your hands and fill up a can or jar under the sink (if it’s good and dry) or some other cool, dry place.
    Once your container is full, spread out the shells on a cookie sheet and bake in the oven at about 200 to 250 degrees, for about 20 to 30 minutes to kill any salmonella .
    Then, I ground the shells up into a fine powder in my blender.
    I did this so the calcium could break down more easily, and also so pets or critters travelling through your garden would not learn to be tempted by eggs and shells as a food source!
