I have read your posted recommendation and several others with singular directions but, as you said pruning will stimulate rapid long shooters - this is what I am experiencing because, it was pruned by the garden center before I purchased the tree.....now I have the problem. When purchased April this year, the tree was 10 feet tall and had been pruned. Now I have about 15 limbs growing virtually straight 6 to 10 feet long and because of their length, horizontal to the ground. Now I need your best advise with this situation!
