I don't know what your soil is like but if the roots can
penetrate it, they can go down to forty feet.

Thanks. I had never heard that before. One (at least this one) would think
that roots going that deep, for a vine, would be pointless. There's
probably a only trace of oxygen and very little fresh water at that depth.
I don't grow grapes, so I have very little reference materials about them.
I may pick that one up, just for the helluvit. =)

I have read that carrot roots cn go down 16 feet.
