I'm not sure what 'plain old juniper' is, so I can't answer that so well. I matched the foliage and bark to my tree books, and 'virginianus' was my best match, but I really don't know .

Why do you recommend clay rather than perlite? This whole soil thing is quite interesting to me, and I am trying to understand better.

And oops on the grow box wood. I have built a lovely 30" 48" x 12" box, but of pressured treated from Lowes, so it is undoubtedly the deck material.
Will the bad chemicals harm the tree?

Thanks.
