I did this all across my backyard starting 5 years ago. Looks great. Always have a lot of people commenting how nice it looks. And SOOOO much fruit in a little space.
In case people wonder if this method can work with any type of fruit. I have 2 different apples, 1 nadia plum, 1 yellow egg plum, 1 peach-plum, 2 different cherries, 2 different asian pears.
