A living fence
I love my goats dearly, but unfortunately, they can jump a 4 1/2 foot tall fence, and don't mind the shock of an electric fence as long as they can get through to that juicy looking bush on the other side. I finally found a fence that is almost 6 foot tall and is an electric net, so they can't just slip through it. It is only meant to be a temporary fence, though, and will not last a long time or be a permanent solution.
I was staring out my kitchen window today and noticed a lilac bush that is so dense you can't even see through the many different stems. I am new to gardening, so I need the advice of people who know plants better than I do.
Would it be possible to grow a fence of lilacs in a few years that would be dense enough that a goat about the size of a very large dog would not be able to get through? If not lilac, are there any other plants that would be thick enough for this purpose?
