How many trees are you planning? I have two orchards one with 15 trees and the other with 24. I have opted to fence each tree enstead of a fence around the orchard. You can use 4 to 5' tall 2x4 welded wire in 12' to 15' lenghts to make roughly a 5' diameter cage. This will keep the deer out since they cannot jump inside. It does make pruning and orther maintenance a little more work. But for a small orchard it is more cost affective. I close the cages with cable ties so it is real easy to open them to work on the trees.
