I've had no success grafting Satsuma Mandarin onto a rough lemon rootstock. All my other grafts (Meyer Lemon, Seedless Lime, Navel Orange, Red Grapefruit) on this rootstock were reasonably successful. Is there an incompatability problem here?
I'm raising some Sour Orange rootstock to try on that.
By the way, I'm cleft grafting pencil-thickness root and scion, as it works any time of the year here.
Thanks for any suggestions.
