I am trying to convert an area previously covered by shingle into grass with
a flower bed on either side. after digging up the shingle I discovered hard
clay, with large large pebbles underneath. I have turned much of this, and
removed much of the stones. I have been trying to improve the quality of
the soil, so that the flower bed would be useable by adding multi purpose
compost. I have read that adding gypsum helps to soften/ break up the
clay. When I went to Wickes to get this they look at me blankly.... can I
just but 'finishing plaster' or does this have cement in it already?

You can get gypsum from the Organic Gardening Catalogue at
http://www.organiccatalog.com/cgi-bin/index.cgi
Price is 6.60 for 5kg, 19.65 for 25kg. According to their web site
you should apply 250-500g per sq.m
