Apple Tree on a Terrace?

Yes, it is possible. And the apples are growing quite well. I have watered all my 'garden' and now we are sitting in our garden chairs, smoking shisha and watching the sunset. It is a warm and quite summer evening and the time when wild animals walk out of the woods into the meadow to graze - just in front of our apartment house. It is usually hares we can observe, but today, for the first time a roebuck has visited us. I am glad to be able to see these beautiful creature so close.
