Ok, so there are dozens of things you can compost, here's a list from pet hair to bee droppings, if you have either of those things lying around. You can actually compost the droppings from any vegetarian animal. In case anyone was wondering...

Moving on to eggs, my friend gave me this bag of eggshells when we were planting some seedlings one night. You may have seen on Pinterest it's popular to take the eggshell uncrushed and plant directly inside it. 

Turns out eggshells have a high concentration of calcium, which is important for building cell walls and can prevent Blossom End Rot. Ever gotten a tomato that looks like this? If so, your soil may be calcium deficient. 

Now it's important to note that the eggshells likely won't break down within the season, so if you're having this problem it's probably best to remedy it with something recommended by your gardener or head on down to the Home Depot. But planting seedlings inside them is a great idea, first of all they're compostable so they'll break down in the soil over time and once they do, they'll provide an additional boost of calcium around the plant.

If you really want to take adding calcium to your garden seriously, you're probably going to have to add lots and lots of eggshells. If you're not bashful you can collect them from people you're close to friends and family who aren't using them. I got mine as a gardening gift. Some of you probably think that's weird, I don't blame you. It's boring, buuut it's part of my life. 

Next thing that eggshells can help with is crawling insects. The sharp edges of the egg shells can cut slugs and snails, acting as a deterrent and keeping them out of your garden. 

So, if you're convinced you've got use for eggshells in your garden here's what you'll need:

  • Eggshells
  • A plastic bag
  • A rolling pin


  • First off, you're going to wash them, any raw egg material brings the threat of salmonella. If you want to be extra cautious you can place them inside the oven on 250Β° for 10-20 minutes just make sure to keep an eye on them. The heat does not damage the calcium content, but you don't want to burn them. 
  • It'll be easier to smash your eggshells if they're a bit dried out. So, if you're not putting yours in the oven it's best to keep them on the counter for a few days just to dry out. 
  • Place dried eggshells inside a large plastic freezer bag and put them on a hard surface. Roll over them with a rolling pin. If you have little ones, they might like smashing the eggshells with their little hands, of you can smash 'em with your big hands if you've had a bad day.
