I watched several of his videos. There were some neat things he did around a pond, creating a heat/cool sink, and a sort of guild around it that allows him to grow papayas. It created a space with a more stable temperature. Also, he uses some of his trees to create frost-free spaces underneath, apart form the pond. It was quite neat to see how quickly they developed this extensive garden, just a couple years.
