Hi Hemple
What a great project! I have a similar plot, though mine is the aftermath of removing a barn. I have very heavy yellow clay, and I am looking forward to testing Charles’ inspirational methods! I have started small with a raised bed full of compost, now planted up, and am going to make another one for raspberries.
I found so this advice very helpful http://www.charlesdowding.co.uk/no-dig-growing/no-dig-growing-preparation/
But don’t waste your effort digging – you will spoil the natural soul structure.
Good luck!
