My espalier system
On either end, I have grapes (Black Spanish and Nesbitt). Along the privacy fence behind the trellis, I have planted Bababerry raspberries and a Fry Scuppernong grapes.
That's four trees and two grape vines in a space that's about one-hundred square feet, or the space that's typically recommended for one tree in a commercial orchard.
You can't see it in this picture, but I've started to run heavy wire every couple of feet to trellis the limbs of the fruit trees, starting at one foot from ground level (for the micro-sprinkler irrigation line) and then about two feet, four feet, and six feet. (I've only run the first two wires so far.) The trellis is seven feet high, which is more or less the exact height of my comfortable reach. (I didn't use a tape measurer when building it, instead relying on my body to tell me how high the trellis should be built and how low the first wire should be strung. The first wire for the tree limbs is exactly as high as I can comfortably reach down, about two feet.)
The whole idea is a system of "human-sized" plants: I won't get on my knees nor will I climb a ladder. It's a rejection of the commercial orchard ethos -- I don't want to maximize production: Instead, I want to minimize inputs and maximize long and varied harvest -- the "backyard orchard culture" promoted by Dave Wilson. What's more, all my reading about tropical apples and pears indicates that horizontal growth and aggressive pruning is the way to maximize production.
Here is my inspiration...
