arbor day cherry rootstock
I called Arbor Day to inquire what their "dwarf" rootstock is that they graft Montmorecny and Early Richmond to. They told me it's prunus besseyi (aka sand cherry). I looked it up and it's a North American native bush type wild cherry. Does anyone have any experience trying fruiting cherry varieties grafted on this rootstock?
They said their standard rootstock is Mahaleb.
I know they ship tiny trees so I don't need to hear about that.
