Does anyone have a composition list for Osmocote Plus? All I can find on the Scott's web page is "15-9-12 plus 9 other essential nutrients." which doesn't mean a lot to me.
I'm using N,P,K, CSM+B, and chelted iron. Is there any reason not to just mix up N,P,K in one set of tabs, CSM+B and iron (or clay) in another, and stick those in the ground?
Is there a benefit to somthing like osmocote over that?
I'm using sand substrate if that matters.
