Hi Mike

Thank you for the reply. The reason I am sitting it on pond liner and slabs
is as my mum doesnt really have anywhere that I can put a raised bed
directly in the earth. I am currently restricted to containers but I wanted
to get a raised bed so I could sow more.

The link is http://www.suttons.co.uk/pd_566926_Raised_Bed_Kit.htm for the
kit that I am looking at.

Thank you
Donna
