Using Crushed Egg Shells in your Garden

I have written about using Kitchen ingredients in your garden to improve your soil. I love using coffee grounds in the Old House Garden as they are especially good for acid loving plants such as Azaleas and Rhododendrons. Recently, I have been trying to add more crushed egg shells to the garden as this is one organic way to improve your soil and deter slugs and snails.

We eat quite a few eggs each week and usually I would add these to my compost bin. Recently, I have been drying them and crushing them up to add to the garden.

Stopping those pesky slugs and snails

I try to garden organically and, at this time of year we always have an explosion of slugs and snails. Although we have an abundance of frogs and toads and a couple of resident hedgehogs that eat these pests, they still munch their way through my perennials. I can’t even grow delphiniums as they just don’t survive! I’ve tried beer and salt traps and these do work to a certain extent, especially in raised vegetable beds but this year I decided to add loads of crushed egg shells to see if this would make a difference. It’s definitely a deterrent as the slugs and snails don’t like crossing the barrier of crushed egg shells. Crushed egg shells also make quite a good mulch, although you do need loads!

Sewing seedlings

Broken eggs are brilliant as mini plant pots and they are biodegradable too! Pop a small amount of soil or cotton wool in each one and sew seeds of your choice.

Use them as a soil conditioner.

Egg shells are fabulous for adding calcium to the soil which plants need to make their cell walls; eggs are made of calcium carbonate. You can ground the egg shells and add them to your soil. They do take a while to break down but it’s worth it for the benefit of the plants. Tomatoes in particular love calcium so you could put some crushed egg shells in the planting hole before planting them. I also think the birds like to eat some of the crushed shell as I’ve seen them flying in to take it.

I hope you find these tips helpful.

    • Ooh thanks Cherylene. I’ll go and take a look!

  • I compost them, but I don’t put them directly into my garden. I have heard of it before. It provides a bit of calcium to the plants, too. We can get a ton of slugs sometimes. GROSS!

    • Hi there, yes, I started crushing uo the egg shells and putting them at the base of my plants and it does work to a certain extent so it’s worth a try.

  • I did not know that anyone else knew about using them for seedlings. That is how I grew some of my first when I was a little tyke. We get many for our compost only because we get compostables from the main kitchen. It is more than I would add otherwise. At home, I did not use many eggs, but saved some of the shells for coffee.

  • Interesting timing because this weekend I was visiting my mother-in-law and I saw that she had egg shells around some of her plants, and she was telling me about how they are great to deter snails and slugs. I have never heard of this– or the coffee grounds. Definitely why I call myself a novice. But glad for blogs like yours to teach me more about gardening.

    • That’s kind! It does work but you do need a lot of eggs shells! Luckily I have a teenage son who loves eating them.

  • I had no idea! What a brilliant idea and a great excuse to eat even more eggs. Which I need little encouragement to do! 🥚

    • They do work Osyth! I have them around my lupins. x
