I’m in the same boat.
I grafted mandarin into mandarin, but grafted oranges, limes, and lemons onto eureka and meyer lemon. Hopefully they do well, but if this isn’t recommended then I’ll have to let rootstock send up shoots and thicken then regraft.
update:
so, last Wednesday and thursday, I went citrus graft crazy and did 64 grafts in about 6 hours (31 cultivars x 2 each plus one double). After a 3 hour session on Wednesday night, I wasn't really up for more... but Behl kindly let me borrow some buddy tape, and I was eager to try my hand with this new acquisition while honing my self-taught grafting skills.
hopefully the meyer lemon interstock lets a little more sugar and flavor through than the standard lemon interstock. I have a few straight rootstock and some more budwood that I'm holding onto for future grafting.
anyone know of any known incompatibility issues?
