Hey thanks for the information! Anecdotally, how long did it take for the eggshells to break down for you (if you kept them in). I'm not planning on using any of this until next spring/summer so I'm not too worried about what will be breaking down short-term.
Either way, I'll have a massive amount of leaves coming in this fall from my property, so this will be 90% leaves when all is said and done!
You’re welcome.
