Eggshells have this great way of benefiting the garden and how we feed the soil is where we cam begin to calculate our successes and failures.
When we compost eggshells into the soil, we’re adding calcium, this is especially important for plants growing produce. Calcium can help build cell walls which allows a plant to grow faster.
Have you ever noticed rot at the bottom of tomatoes prior to harvesting? This is due to lack of calcium in the soil.
This happened to me several years ago; it was a simple error that could have avoided.
I failed to pay attention to where I was adding shells, then went ahead and planted tomatoes in the same location as the previous year and every single piece of fruit had bottom rot.
When I figured out what was wrong, I started adding eggshells immediately and my fall harvest that same year was better.
Plants are always pulling nutrients from the ground and if the soil isn’t fed the right nutrition it will have an impact on your garden.
Eggshells offer additional perks and we’re going to take a look at those benefits and how to add this ingredient to any space.
How to add Eggshells to the Garden
Free-range chickens lay eggs with thick shells, which means they hold a lot of nutrients and why our eggshells always end up in our raised beds.
You can add any kind of eggshells to your garden we just prefer farm raised becasue they taste amazing!
Over the Fall and Winter, add Shells via Direct Composting Like This:
- I first rinse the eggshells then dig a hole in any raised bed.
- Add the shells to the hole and crush with my shovel.
- Finally, cover them up.
This takes just a few minutes and it works like a charm.

If you have resting beds and already have an idea about where you’ll be planting peppers, squash and tomatoes the next season then add eggshells directly to those areas.
This step will detour bottom rot the next growing season.
With that being said you can also add eggshells where existing plants are growing year-round. I even add them to my rose beds.
Adding directly to the soil allows nutrients to begin breaking down instantly and while they’re breaking down, nourishment is being released into the soil.
Now, if you’re a compost bin gardener then it’s easy enough to just add eggshells directly to bins as you visit the garden. Make sure that compost is added to all planting areas prior to spring planting so your plants can benefit.
Eggshells in Containers
Eggshells can also be combined into planters. A good time to do this is when your establishing new containers or transplanting.
They can even be added to houseplants because guess what? They need nutrients too and they can benefit from calcium.
I’m no expert on houseplants so make sure to do your research ahead of time.
To Add Eggshells to Containers, Follow These Steps:
- Add crushed eggshells to the bottom of the container.
- Cover with soil.
- Add new plants, seeds or bulbs (whatever your planting).
- Finish securing plant with soil and water as needed.

Adding Eggshells to Detour Pests
The final way I like to add eggshells is to mix within mulch, I normally use a combination of mulch chips, leaves, small sticks and eggshells.
If I have garden gloves on, I just crush in my hands. I found this to be faster and there’s no dishes to wash afterwards.
This step is another way to benefit the soil and detour some pests including slugs.
This isn’t a pleasant detour as it can result in pest cuts where they bleed out. I know that’s kind ugly, but it is natural…
You’ll notice I only add a few eggshells to my mixture and this is mainly for the nutritional value.
However, I think this actually helps keep the racoons and possums from messing in the garden more than it keeps bugs out.
Adding natural nutrition to improve the soil is the best way to help your plants grow their best.
This is a simple activity, easy to implement year-round by just visiting your garden, digging a hole, and emptying eggshells in the mix.
