Buying Fruit Trees Tips
A pet hate of mine is looking at a fruit tree for sale in a nursery and not knowing whether it is a seedling, cutting grown or marcotted. You can usually tell if it is grafted as you can see the graft and it usually has this information on the label but a lot of times it does not even detail the rootstock. When you start out putting in edible trees, you think it will produce fruit in a short period of time and it just might not if it is a seedling! I have a very old Star Apple which must be 30 years old and it has never flowered nor fruited. Ref: Sheryl Backhouse
Lack of fertiliser will also be a reason for non-fruiting trees.
