In 2021 we experience a catastrophe known well by many farmers.  Hail completely destroyed the crop just days before the harvest.  In about 3 weeks the plants grew back to about 30% of their normal full yield.  We held a Saturday-only harvest event that was attended by a much smaller than usual group of rhubarb enthusiasts.  The attendance matched the low yield perfectly.  Just enough rhubarb for those who came.
