I've been playing with the living fence thingy for a few years now with small successes but overall not much headway. Until this year. This winter I noticed a willow that had fallen over a couple years ago, and had sprouted vertical sprouts that now are 20' tall and 2" around each. Those "shoots" form a picket type fence the length of the fallen log. It inspired me to try to create that same situation, and when I woke up one morning in March with my cows in the road, I found my motivation!
So, I came up with an idea, that I would lay willows over by making a back cut about halfway through the tree and pushing it over. Basically forcing a barber chair type felling situation, so the tree would stay connected to the roots on one side. Well, I did that to some areas I was struggling with fencing, and for a while just the laying down logs were enough to contain the animals. The cows and sheep loved to graze all the new shoots, so the inner parts are pretty leafless at the moment. Due to their foraging I added a little woven wire to this section to keep them out of it. I think in a couple years this is going to impenetrable!
Here's a couple photos. All of the little green shoots you see in the near background are new in the last few months. The future fence.
