Not sure that most of em are grafted on lemon stock though. They are usually grafted onto trifolia stock,mostly because of the coldhardiness and stregnth of the trifolia.

That lemon grafting is what I was told years and years ago......like the internet, it might not be right.

trifolia stock....??? Now I need to do some more studying to learn more.
