Reuse eggshells – don’t throw them away! If you’ve been tossing your eggshells, I’m about to convince you to keep them. We eat a lot of eggs around here, thanks to our backyard hens. But you won’t find any eggshells in my trash cans. I reuse my eggshells and you can too! There are so many ways you can reuse eggshells right on your homestead.

8 Fantastic Ways to Reuse Eggshells on the Homestead

1 – Compost them!

Eggshells add lovely calcium and other trace minerals to your compost. Then later when you use your compost those minerals will help your garden grow. You can put eggshells straight into your compost bin or let them dry out, crush or pulverize to a fine powder for faster breakdown. Also see 10 Things to NEVER Compost

2 – Feed them back to your hens!

Yep, that same calcium you can feed to your compost can also be fed back to your hens. This will give them stronger egg shells (win!). Let your eggshells dry out a day or two. Then crush them and lay them out in a single layer on a cookie sheet. Bake the crushed eggshells at 350 for about 5 minutes. Before you feed them to the girls, you want to make sure they don’t look like eggs (don’t want to teach them any nasty habits); so you can crush them down a bit finer after baking. Then just mix this up with their regular feed.

3 – Start some seeds in them!



You can reuse your eggshells as seed starters. Forget buying pots – eggshells are the ORIGINAL biodegradable seed pot. Check out Frugal DIY Seed Starters on how to use your eggshells for seeds.

4 – Give them to your tomatoes!

If you grow tomatoes then you know all about the dreaded blossom rot. Well, did you know that eggshells can help you fight it? Use a coffee bean grinder to make your eggshells into a powder (you’ll need a dozen per plant). When you’re ready to plant your tomato seedlings, just add the powder to the hole first. This will give your plants a boost of calcium (easier to use as a powder) right at the source. See How to Grow Tomatoes

5 – Keep nasty pests out of your garden!

Use eggshell powder to dust leaves – killing beetles and preventing their return. Crushed eggshells in the soil can prevent slugs and snails who prefer to steer clear of the sharp edges. Also see Dealing the Aphids Naturally

6 – Clean your garbage disposal with them!

Ok, I know you’ve heard that eggshells in the garbage disposal are a BIG no no. But in moderation they can help clean off the yuck down there. Don’t believe me – check out Fix It Yourself.

7 – Use them in your vermicomposting!

If you’re vermicomposting you can feed your little worm workers by reusing your eggshells as worm food! You’ll want to pulverize your eggshells to make the easier for the worms to eat. According to Uncle Jim’s Worm Farm eggshells can be a great food source and bedding material.
