I was going to say that it doesn’t seem to mind.
Grows quite happily left in the dark with a covering of shit every now and then.
Bit like mushrooms and voters.
But then I noticed that in the industrialised process the plant apparently only survives one season of forcing (because they keep picking all year long rather than just picking the initial shoots in spring and then letting the plant rest over summer and winter).
Unforced rhubarb - I’m not sure it ever dies.
You just keep dividing it until it’s taken over all available space and by then it’s probably SEP.
You can force your own rhubarb without needing heated sheds, etc. Just stick a big enough pot over the plant in winter.
