I appreciate the video links, I find it very interesting what Campbell is attempting to do. I do see a few discrepancies in his comments, maybe I heard him wrong, he mentions that trees are planted at about 10 ft apart. and in one part of the video says he will increase the amount of trees per half acre, later he says he might have to pull some out.
It will be interesting to see if he is able to keep plants dwarfed solely by pushing production. having so many trees so close together, with little circulation seems like an invitation for fungal problems down the line. and although I always support the idea of keeping the garden industrial chemical free, and love the idea of trying to be sustainable as possible, its seems like this will be very labor intensive, pruning 250 trees, and doing almost all other labor manually. I do respect his experience, and learned a few things in these videos, also gave me some ideas of my own.
I am not too clear on the so called proprietary varieties he intends to patent, are these non-mentioned varieties or the ones he mentioned in the video? could they be the new hybrids mentioned by Noris in another thread?
