Why not graft the pecan to the dwarf hickory?
Well, Gordon,
That had crossed my mind, but I don't know how well that would work - I'd
be concerned that the more vigorous pecan, on top of a hickory rootstock,
or even a hardy pecan root with a 'dwarfing' hickory interstem, would
'outgrow' the hickory, and be prone to breakover at the graft union.
Perhaps it's a misplaced concern, but some of the long-timers in the KNGA
had warned me about this phenomenon when I first got started playing with
nut trees, but I've not actually seen it.
