Thanks to everyone who gave some insight about germination for the
plants that I posted a few days ago!

This is the first time that I finally have the space and facilities
to do things right, so I'm excited and looking forward to lots
of new plants this year.  Hopefully I'll do ok! 

I have a question about acid scarification.  A couple of the trees
that I was going to try growing (Cercis and Koelreuteria) require
acid scarification.  Fortunately, I was able to get my hands on (not
literally, of course) some sulfuric acid concentrate.

I don't know if I'll have access to it in the future, though.  What
do all of you do?  The archives suggest using a rock tumbler, but
I don't have access to one of those, either.  Can I just soak the
seeds in Liquid Plumber?  Or is there a source for sulfuric acid?

Thanks,

Chris
