With my little bit of ground (L shaped garden 7metres x 22metres) I have been working on my "food forest in zone 2 combined with my zone 5(??) native trees and shrubs" and my "urban garden" close to the house in zone 1. My request for advice concerns how closely I can plant my fruit trees and natives - I'm not looking for a "glut" of fruit from a single tree, rather a variety for throughout the year. I've researched until my eyes are hanging out of my head and I haven't found how close you can plant fruit trees to restrict their growth but still have them viable and producing fruit while surrounded by other food plants "a la food forest". So far I have 8 fruit trees in the zone 1 garden mixed with iris (to take up the excess nitrogen when the trees are dormant) and I plan to put quite a few more in the "food forest area" now that my canopy trees (natives) have grown. Any advice will be welcome otherwise I will begin making "learning experiences happen" again, and again until I get it right.....but think of all the little fruit trees probably starving to death in the meantime
Zone 2 food forest is approximately 7m x 18m and the balance is zone 1 urban.
Edit: all measurements done in girl steps so may not be quite accurate (stepped out, then reduced, to get approximate length and width)
