Every Sunday, I make a great big breakfast that results in the entire family being pleasantly stuffed and ready to take on a full day of gardening and (in fall) football-watching. Because we have a big family, we go through a dozen eggs every Sunday. Happily, there are several great ways to put all of those eggshells to use in the garden.
How to Use Eggshells in the Garden
1. Compost them. Rinse them out (or not. I rarely bother with rinsing mine), crush them up, and toss them in your compost bin.
2. Add to planting holes. Crops that are prone to blossom end rot, such as tomatoes and eggplants, appreciate a little extra calcium in the soil. Simply crush and sprinkle a few eggshells into each hole at planting time.
3. Deter slugs and snails. This tip is hit-or-miss for some people, but it’s worth a try if your lettuce or hostas have become a snack bar for these slimy buggers. Crush up a few eggshells and sprinkle them on the surface of the soil around any plants you’re trying to protect. The sharp edges will (hopefully) irritate the underside of the slugs or snails when they try to slide over them, and they’ll stay away.
4. Seed starting pots. If you are careful about cracking your eggs, and only crack up the top part, you can save the bottom, intact part of the eggshell and use it as a pot for planting seeds. Simply fill it with seed starting mix, plant your seeds, and watch them grow (you may want to try to poke a hole or two in the bottom of your shell to ensure adequate drainage). Best of all, once it’s time to plant, simply plant the whole thing, egg shell and all.
I hope these tips have you looking at eggshells in a new way — they are so useful in the garden!
