I then put another load of muck in and covered this with soil. I then got my black plastic and put the plot away for the winter.
Black Plastic!!! May be because I am lazy, but I find it the easyist. The weeds do not bother to think about it, the soli warms up better, the worms can come and go as they please, and they do please. So all in all job done. Yes it does look a bit ugly hence the reason for trying to square it away. Either that or weeds.
