5 Ways to Reuse Eggshells

An Egg-shell-ent Resource

The next time you crack a few eggs to make breakfast or a baked good, don’t toss away the shells – repurpose them! From soil additive to herb garden, eggshells provide an egg-cellent resource. See below for just a few ways you can give your eggshells new life. What’s your favorite way to repurpose eggshells?

Eggshells used as planters for seedlings and inside egg carton.

Herb Planter

1 – Prep & Wash

Use a sharp knife to remove the upper ⅓ of the egg, we recommend cutting off the smaller end, and leave the bottom ⅔ intact. After it’s cut, wash the shell thoroughly!

2 – Cut a Drainage Hole

Using a small needle or scissors prick a small hole in the base of each eggshell. This will provide drainage for your herbs. It’s best to do this when they are still wet to avoid developing any cracks.

3 – Plant

Fill each eggshell with soil (a kitchen spoon can help make this easier!) and then plant your herbs! You can use seeds or small stems.

TIPS:

  • Water with a spray bottle once per day
  • Keep in a warm & sunny spot – in front of windows are a great option for this.

Soil’s Best Friend

Crushed eggshells are an excellent soil additive 

  • The calcium from shells is welcome in garden soil, where it moderates soil acidity while providing nutrients for plants.
  • It also helps keep slugs, snails, cutworms, and cats away

Eggshell Compost

Adding eggshells to compost will help add calcium to the make-up of your final compost. This important nutrient helps plants build cell walls. Simply crush up your shells and add to your compost pile!

PRO-TIP: Did you know our cartons are also compostable?!

Calcium Water

A concentrate of eggshells in water provides a great dose of calcium that can be used to water plants.

1 – Prep

Boil a gallon of water, and then add 10 clean and dry eggshells to it. For a stronger brew, add the shells of up to 20 eggs. 

2 – Brew

Let the shells sit in the water overnight. Remove shells from water – what’s left is your concentrate!

3 – Utilize!

Pour the concentrate directly onto the soil to give plants a boost of calcium and potassium.

Succulent plants planted in eggshells and in an egg carton.

1 – Prep

Use a sharp knife to remove the upper ⅓ of the egg, we recommend cutting off the smaller end, and leave the bottom ⅔ intact. After it’s cut, wash the shell thoroughly!

2 – Fill the shells 

Using a spoon, fill each eggshell about 3/4 of the way full with potting soil

3 – Add the succulents 

Create a small well in the soil with your finger, gently place the succulent root into the well, and lightly pack the soil around it. If needed, cover with a small amount of additional soil to help anchor the succulent.

4 – Water

Immediately give the succulents a light spritz of water from a spray bottle and set them in a spot with great natural light.

As far as future watering goes, just keep an eye on the succulents. To avoid overwatering, the soil should feel completely dry to the touch before you spray with water again.
