Answer: What you describe sounds very suspicious! 'Owari'has oblate to rounded, medium sized fruit with slightly rough peel, becoming lumpy and fluted with maturity. The pulp is orange, of rich, subacid flavor; nearly seedless, (sometimes 1-4 seeds). The tree is small, almost thornless, large-leaved, with faint or no wings on petioles. I wonder if the rootstock has overtaken the graft and you're not growing Owari at all. Check the grafted area and follow the branches back to the trunk. You may discover that the graft has died off.
