Electric fence material

I started with the 2 row fence when I started my orchard in 2015. I have about 115 trees in about 1 acre. I put 2 outer strands and 3 inner strands. I have never baited the fence. The fence worked great until that fall when I started to see a little browsing and deer inside. A year later, it had 3 outer strands up to 36" high and 5 inner strands up to about 60". The top inner strand is the yellow stuff, the rest is steel wire. They still get in but usually more to feed on grass and weeds rather than the trees. I had a little buck rub on one tree’s branches last fall. I have a bunch of small cages on various trees and no cages on the rest, mostly larger trees. I have been lucky that nothing has really been damaged. Since I planted out some bench grafts and did t-budding, not having the trees caged was nice for working on them. If I had to do it over, I would transplant from the nursery and cage.
