The rooting medium need only be 4" deep and the cutting should not be

Maybe Paghat will chime in here. I have never tried to propagate any
trees but bought the book for reference and futere use.

I have to look up "heel cuttings". Of course, why I, with a black thumb
or two would even attempt this is a mystery--except for the fact that I
love Japanese maples....
