Hello all, I have a mature orange and tangerine tree that pump out a lot of great tasting fruit. Is it possible to graft a lime or lemon scion onto the mature trees? I have a small mexican lime and variegated lemon I would like to get more fruit from and was hoping to be able to graft scions from them onto the mature trees. All the grafting info I have been reading appears to show smaller trees that are being grafted rather than mature trees.

If yes, what is the best way to do this?

Thanks!
