Any way you could plant right down the center of that plot and hinge the crap out of everything on the south plot edge to knock down the towering height of those trees casting the shadow half way across the plot? You would be farther out from the trees(and their root systems) on the north edge(all edges for that matter) and get tons more sunlight on not only on the center, but the south plot edge as well. Win-win in the long run. You could still plant the strips outside the line of trees that run down the center, maybe LC mix on one side and brassicas on the other and then rotate them each season.[/QUOTe
That thought had crossed my mind. But the wife isn't to keen about cutting more trees.
