Hmmmm.... I could do a small experiment then, by not digging the 3x3 metre area which was covered in fresh horse manure late October, as I mentioned earlier, so just leave it and plant straight in it? No prep at all?
At the moment it is covered in plastic sheeting, as advised by someone down the allotments, should I now leave it open to the elements, or have I left everything too late to do this small experiment?
