Bob,

I was really trying to keep it simple, but of course you are right on
both counts. Rooting harmone is such a natural part of the process
that I don't really think about it consciously. However, I am less
sure he will find lots of naturally layered rootings. I've found very
few, and I have looked at hundreds (thousands?) of wild muscadines....
