This garden would not lend itself to machine harvest . I would think that most farmer would not go for this method unless machine could be use to harvest the food . Too time consuming to walk the whole garden to harvest . Glad someone is trying hugelkultur on a large scale . It would nice to find out what problem they ran into now and in the future .
Considering many conventionally grown fruit and vegetable crops are not harvested by machine, but by hand, I'm not sure it's a special problem that hugelkultur probably can't be harvested by machine. The need to harvest by hand is a problem faced by many or possibly most small-scale vegetable and fruit farmers.
