Richard Hentschel, host of Green side up talks about why don't fruit trees bear. In many cases, trees are too young or in a vigorous vegetative state. Fruiting can be delayed if proper scaffold training has not been done that will promote early flowering. Improper pruning can also delay flowering and fruiting. Of course there also needs to be cross pollentation for the apple trees. Making sure you have adequate pollenators blooming at the same time
