Just got the keys to the house with a small wilderness attached. There had been a lot of rubbish in the garden and it seems that the previous owner piled all that, plus household detritus plus BOOKS!!!!!!! (sorry to shout) into a big heap and set fire to it. We now have a hollow area about 5ft x 5ft which is full of ash and left over bits of unburnt metal.
What, if anything, should we do to it? Friend says dig it in and grow carrots. OH's back says digging not an option without mechanical assistance.
Advice please? We've never had a big garden before and certainly never one in this kind of state.
