Espalied Trees

I've always wanted to grow lots of things in my yard, especially fruit. I discovered a way of growing fruit trees that takes up minimal space. It's called espalied. Basically you train your trees to grow out sideways along some wires. That way they don't come out into your yard. I'm giving it a try. I have a pear, plum, cherry and two apple trees. Here is what they look like right now.
