Dizzy, is it necessary to cut them and put them on sticks? Having read your first post, I rushed out and bought some Covington variety. I have them uncut in tubs with water half-way up the tuber. Wouldn't this amount to the same thing?
Has anyone got a link to sound advise in these creatures? I have space in the polytunnel but am not sure about whether to manure/use black plastic/seaweed etc.
