Well, I was trying to put a pic of what we've done in our in-town backyard, but am having trouble getting that to work. Anyway, we built a garden bed around the periphery of the back half of the back yard. So it's like one big garden bed about 2.5 feet wide (didn't want it too wide since we can only reach it from one side. Then we have some freestanding garden beds in the yard (also back half--tried to leave the front half for dogs and kids to use as well as putting up the pool in summer). We never had success with fruit trees prior, so this time we planted them in the garden bed on the periphery, and the enriched soil seems to be helping them. They've grown well this time. In that bed, we have an apple tree, two peach trees, and two cherry trees (one tart and one sweet). Nearby, but not in a bed, we have a second apple tree for pollination. In the front yard, we have a large old mulberry tree that came with the place and produces well. We added two pear trees last year, and a self-pollinating plum tree just last weekend.
P.S. Just wanted to add that the only downside I've really had as to having the garden towards the back of our yard (which is about 60 feet wide) is the occasional time when I need to water with the hose. Got to have a long hose!
Updating to say I got pics to work!
