I've collected quite a lot of cuttings from fruit trees and some are bearing roots. It includes apple, peach, plum, nectarine, apricot, cherry, grape and more.
I want to plant them all pretty close together- about 1.5 meters apart- along my fence. I've read this way they'll self-prune each other and I can fit a lot of different fruit trees in a small space like mine.
How many years should it take before these small cuttings will bear fruit? I've heard maybe 7 years? I'm wondering if it's better to just buy dwarf trees at $30 each which will produce fruit within about 3 years.
Also, is it just a fantasy to fit lots of trees close together this way and actually work?
