A thirty year old forest garden (the longest standing intentional food forest garden in Britain according to Permaculture Magazine) fully equipped as a teaching space with major improvements to our household in terms of energy efficiency. Last year (2018) we have grown over a tonne of food in a fifth of an acre (800 sq metres or .08 of a hectare). Peak yield has been 1.25 metric tonnes of food. This is a yield rate pro-rata of 16 tonnes a hectare, twice what even the best chemical farmers produce here. For the last many years we have also produced our own firewood and half our electricity, and operated a working plant and tree nursery in the same space. We are now changing that arrangement as we are getting older, but the garden is still highly productive. We continue to teach courses here and off site. Our main expertise and interest are Permaculture Design (introductory, full design course, and advanced), Forest Gardening, Food Preservation and Permaculture Training of Teachers.
