Finally!!!
Found info about bonsai mixes and how to prepare...that was to the point and not at all confusing (for me, at least)! I had still been having reservations about using chicken grit in a bonsai mix and binged about it...came across this site:
http://columbusbonsai.org/cont...
Some will say, "Yes, I knew that." But for me, after countless hours of research on the internet and reading various forums, I would only come away with more questions.
So...glad to share this link for anyone who, like me, is just now venturing into "bonsai."
