So... I saw this pin on pinterest that alleged that if you ground up eggshells in a coffee grinder and sprinkled them among your plants, they'd work much like diatomaceous earth... getting inside the exoskeletons of garden-raiding insects.
I eat a lot of eggs. This is a resource I have in abundance.
So - what could it hurt? I just used a rolling pin though (probably won't be as good, but we'll see).
If nothing else, I'm adding needed calcium to my veggie soil.
Did I say that I/we eat a lot of eggs? Yes? Good. ;)
Last year my lettuces looked like lacework. I have lettuce planted in between my tomato plants, and I'd dearly like to eat it this year.. wish me luck!
