Eggshell seed planters are perfect for kids! Plant a sampling of seeds inside of eggshells and when the weather warms up plant the entire thing into your garden! A fun lesson on composting and reusing everyday products for a new purpose. This post was originally shared in 2015 and has been updated to include a step by step video.

We’re always anxious to start planting once March rolls around, but it’s still a little too cold to have our seeds outside. Eggshell seed planters are a great option! Start the seeds inside, then transplant the entire shell into your garden in a few weeks!
Not only are eggshells practical, they are good for your garden too! With 6 happy hens wandering around our yard, we have lots of fresh eggs and lots of fresh egg shells.
We’ve grown vegetable and flower seeds in eggshells with great results!
How to Make Eggshell Seed Planters
Eggshell Seed Planter Supplies
- egg carton or egg holder
Step 1: Collect Egg Shells
Every time I used an egg I rinse out the shells and set it aside. It doesn’t take long to save up enough to start a dozen seedlings—the perfect amount for a sample starter pack for a kids garden. Grow a dozen different little plants of a few of each, it’s up to you!
Step 2: Find something to hold egg shells
You can use an egg carton to hold your seed planters and toss it in the recycle bin when you are ready to plant your shells, but I chose to use one of my ceramic egg holders.
Step 3: fill each shell with soil
Fill each shell with potting soil.
Step 4: add a few seeds to each egg shell
Add your seeds and cover lightly with soil. Kaylee chose to plant chives this time. We like planting a few more seeds than we think we will actually need. This way we have a better chance of having some sprout. You can always thin the seedlings out later.
Step 5: Water
Spritz with water and place them in a sunny location. You can cover them with a piece of plastic wrap until they start to sprout to hold in moisture too. We found it easier to spray them with water when they needed moisture vs. trying to pour water into each shell.
Step 6: Watch the seeds grow!
Place planters in a sunny location and watch them grow! What a fun way to re-use eggshells. Not only are the little shells practical, but they are good for our plants too.
What is the best potting mixture to use for eggshell seed planters?
I used the same soil that we use in our raised beds, but the ideal mixture would be a seed starter mix that does not contain soil. You can buy this at your local gardening store.
Can I use an egg carton instead of eggshells for starting seeds?
Yep! Egg cartons are biodegradable. You can do the same exact thing as you do with the eggshell. Cut out a section of the egg carton after the seeds have sprouted and plant the entire section in your garden. Source.
Are there other ways to use eggshells in a garden?
Eggshells are a great way to add minerals into your garden. You can till them into your garden, add them to the bottom of a hole before adding a plant or sprinkle them liberally across the top. They take a while to break down so you can add them in the fall and again in the spring for year-round results.
