Egg Shells for the garden use

Now I know that I could put together a big list of uses for egg shells, and I might do a top ten list someday but this post is about the shells and garden use.. if you own a small backyard flock, spring is the first flush of eggs and with the egg glut, also come lots of egg shells for your garden use

The First use is dead easy, wash, crack and throw them in the compost pile in a scattered way and cover them in the next layer and let them do their thing, I love that when you turn it, you will often find earthworms cuddled up in a half egg shell..


So tip number one, after your first really hot compost and you want to draw more worms, egg shells really seem to help on this

But if you want to use them for the next two way, they need to be dried.. you can air dry, I like to bake them at the lowest setting possible


Wet Shell crushing, it looks good to the layman but no.. this is not going to get the job done


Dry shell , now we are getting the right way.. the wet shell had a few sharp edges but over it collapsed into itself, where now we have hard and sharp but it also will have crush into bits easily, now this, this is perfect to be scatter around tender starts or any plant that needs slug or cutworm (really any soft bodied warmish), the edges cut them and after it will feed the soil when turned in at a later point


but we are not done yet, nope I took my  bits and hit them with the garden coffee grinder and voila.. 0 mile organic calcium rich soil amendment, I love this to use in the soil for each tomato plant, each large shell should make you around one scant tsp, I like to use about a tbsp. per tomato plant hole in the garden ( this ground shell is also excellent to be sprinkled back onto your hens feed)

*The main ingredient in eggshells is calcium carbonate (the same brittle white stuff that chalk, limestone, cave stalactites, sea shells, coral, and pearls are made of). The shell itself is about 95% CaCO3 (which is also the main ingredient in sea shells). The remaining 5% includes calcium phosphate and magnesium carbonate and soluble and insoluble proteins.


Do you use egg shells in your garden.. if so which method do you use and for what plants or areas

    We don’t have chickens so it’s just crush & compost here. I like the ground up idea, never thought of doing that. I do walk the beach and gather oyster shells. Break them up with a hammer and toss them into a garden hole. I also use them to catch slugs & snails and I’ve observed the black birds going through the garden flipping them & gobbling them up.

    Short answer… “Yes” & “Yes” to both of the above and more (but I’m guessing that’ll be tomorrow’s post?; )
