It has one branch each for 5 different apples, one Fugi branch, Jonagold, Akane, Gravenstein and one Liberty branch. It is producing more fruit this year than last year, but not on all branches. The Jonagold and Gravenstein branches have no apples. I did not know about pollinating. Do we need to pollinate this tree, like a lemon tree? Show more
