Are we talking about 'proper' forcing, i.e. digging up the crown and exposing the root to frost, then taking it into a warm darkened shed to produce pink rhubarb?
are we talking about placing a forcing pot or chimney/bucket over a crown of rhubarb growing in the garden to blanch the rhubarb which is produced only a short while earlier than normal?
I do the second every year with a mature crown, but I don't pull any rhubarb after the end of May/early June - this way the crown builds up again before the winter and is not damaged.
