Egg shells also prevent root rot if crushed into the hole before you plant your seedlings but planted like your picture Stephanie it would take forever to breakdown 😊

Their better off ground up in a coffee grinder and add to worm farm or scattered around the plants so the garden worms can make use of them. It helps worms digest plant matter and they poop it out in there casting

I tried putting crushed egg shells into my compost to add calcium to my garden. It’s probably ten years now since we did that and I can still find pieces of shell in my soil. They simply do not break down very well. I also stopped using coffee grounds. That’s my two cents worth on the egg shells. Happy gardening… ;-)

Hi Esther, I’m glad that works for you. The studies say that the eggshells take a long time to break down to add the calcium, and even so, it’s not water soluble so it needs to be consumed by soil wildlife (like worms and insects) to be available to the plant roots. That said, it can’t hurt! If you have plenty of them then why not? I would worry about restricting the upper roots so it might be best to crack the whole eggshell, rather than just the bottom. Have fun!

great tips!
