Citrus General Discussion / Re: Trifoliate graft incompatibilities?

Howdy Brian,
Traditionally, the Japanese would bridge graft between the PT/FD and the mandarin before the shouldering restricted sap flow excessively. This was typically done with yuzu scions and would extend the trees' productive lifespan indefinitely. I'm not sure if other scions would also work.
Given the horticultural skills of the Japanese, they've no doubt created a magical rootstock that eliminates the problem, but the traditional remedy might be just the ticket. I have several mandarins planted in the ground in my greenhouse and their bud unions look like yours. I plan on picking up a yuzu in the near future to give the method a shot.
