Hi Grasa,
Nice video.
That guy "should" go several times in the year in that yard and report on the different crops.
Seeing trees so hard pruned is beautiful, but I'm not sure that they would really fruit a lot ... But still good ideas ( and surely lots of work, and expenses for watering ).
Seeing all the citrus trees ... Well, he is not in a 7/6 zone I guess .
I'll stick to fig trees, peach trees and pear trees - They are doing almost fine here .
