Of my 3 rhubarb plants, all grew fairly well to well last year,

I assume that I have to start again, but is that likely to mean
that I need to get new stock (as distinct from taking offsets)?

I don't know. I have never had anything other than vigorous growth out
of mine on a heavy clay soil. It gets forced most years but then left to
its own devices when we get fed up with rhubarb.

Last year was a bit peculiar with the warm weather as the unforced plant
had new shoots on Xmas day sufficient for rhubarb crumble!!!
