We planted over fifty different fruit trees in the garden of our Blackberry Lane house. They were planted in an area of compacted and contaminated road fill outside the shed that had once been a truck maintenance garage and a car demolition yard. After clearing it and bringing in countless truckloads of new top soil we used an industrial post hole digger to break down through the compacted layer which was like concrete. We found much archaeology from car parts to bottles and broken crockery.
The trees thrived and were just beginning to fruit heavily when we left. We knew we would be feeding the birds more than ourselves but that still made us happy.
