Q.SOIL IMPROVEMENT I had a large delivery of soil delivered to my allotment 12 months ago. It contained a large clay content. I a
dded some compost following sieving and have grown onions reasonably successfully but not so with beans and raspberries. I am now growing some green manure for chopping and digging in late summer. Do you have any advice on a particular soil type which I might mix with this clay based item?
Thank you.
