Hello,

I have an olive tree in the garden that doesn't seem to be fruiting. It's been over 20 years, maybe more, since it was planted, and it has never produced any fruit. It's a grafted plant, and the only portion of the tree that produces fruit is the rootstock suckers.

Does this mean that I have a non-fruitng scion variety grafted on a fruiting rootstock? How can I confirm this one way or the other? Thanks in advance :)
