Eggshells: Nature’s Perfect Seed Starters

Eggshells: Nature’s Perfect Seed Starters

It might not be spring yet, but the time to start planting seeds is just about here! If you have a greenhouse, or a sunny window at home, you can begin planting and growing seeds indoors now, to transplant in your kitchen garden. Gardeners know the importance of enriching the soil. So, here’s an easy, natural and inexpensive way to give your vegetable plants a great start and enrich your garden bed in the process.

Save your egg cartons and organic eggshells. Keep an empty egg carton in the kitchen. As you crack an egg, place the empty shell halves in the egg carton. If the egg didn’t crack evenly, place it in the egg carton anyway. You can place another eggshell on top of it. When your carton is filled with eggshells, you’re ready to fill them with a quality potting soil, seeds and water. Place in front of a sunny window, or beneath a grow light to give your spring planting a jump start.

When it’s time to transfer your seedlings outdoors, tap the bottom of the eggshell with a hand trowel to crack it and plant the seedling within its shell directly into your garden bed. Cracking the shell will ensure proper drainage and allow the shell to start decomposing and nourishing the plant roots and garden soil.

Eggshells are an organic, biodegradable plant pot that adds calcium, nitrogen and phosphoric acid to your garden soil. Eggshells are also useful as a snail deterrent, protecting tender garden plants.

Happy Spring Gardening!

My grandpa always crunched up eggshells and coffee grounds directly into the garden, especially for tomatoes. I picked up on this but never thought to put those nutrients to use by planting in the eggshells. Wonderful idea. Thanks!

By the way, I try very hard to plant by the moon. Planted the seeds with the moon, in egg shells and they are doing great. I’ve planted with the moon for 43 yrs, Gramma Sturtevant taught me. No other way is there? Seeds and plants grow but not as well as with the moon. People laugh at me when I talk about it but I don’t care. I know it works!

I did this. They are by far the best plants. The seeds that were planted in plugs are ok but not as good as the ones in the egg shells!

This would be especially good starting cucumbers as they loved egg shells.

My grandfather was using this method, back in the 60’s. Just thought it was being frugal.

Thank you so much for this brand new exciting way to start seeds, I’ve been gardening a lot of a lot of years, and this is the first time I’ve seen this idea. So unique. Definitely will be using this technique starting right now.

Hi Anne, No. All “organic” means for eggs is that the chickens are fed organic feed. Any old eggs will do.

Do the egg shells need to be organic?

If you notice a hole in the upper left-hand corner of your Farmers' Almanac, don't return it to the store! That hole isn't a defect; it's a part of history. Starting with the first edition of the Farmers' Almanac in 1818, readers used to nail holes into the corners to hang it up in their homes, barns, and outhouses (to provide both reading material and toilet paper). In 1919, the Almanac's publishers began pre-drilling holes in the corners to make it even easier for readers to keep all of that invaluable information (and paper) handy.
