A YOUNG COX'S ORANGE PIPPIN APPLE TREE
This is the second year my newly planted apple tree has been in my garden and is doing well. It had a lot of blossom this year and a lot of it set to form small apples. As it us a new tree I took most of the fruit off leaving about 15 fruits. I water it well. My question is do I trim the new growth fully off, half off or leave them alone? Please see photos. I do not want the tree to get too big. It was purchased on dwarf root stock.

One of the reasons the tree is growing so vertically could be the surrounding tall shrubs, which it is trying to compete with.

If you checked the eventual height you will get from the dwarfing stock used you will not need to try to keep it smaller by pruning. Its important to choose the stock that gives you the size you want. There are several different dwarfing stocks, the smallest being for pot grown plants.
This gives you a table of the various ones with eventual heights.

There's a lot of info on pruning apples on line, and some have videos - better than trying to describe it here.
Your tree looks very nice and healthy - enjoy your apples!
