The tree in the background is an old apple tree. I'd guess we can think of it as a single tree, for all the different major branches emerge from the same trunk.

Hehe, yes, I think that a good gardening philosophy is to only plant that much one can easily take care of - too much stuff growing and it might turn to a stress factor, if one constantly feels that there is always a pressure of things-to-be-done. So, having time to admire the beans growing happily sounds like a gardening success to me - after all, it is meant to be a source of joy and happiness =)
