1959. At one time Morley used to have many acres of rhubarb fields with massive but low forcing sheds. The main time for harvesting forced rhubarb was from late December to early April when little other fruit was available. When taken out of the forcing sheds the roots needed nearly two years to recuperate before they could be used inside again. Towards the end of this period they were growing well again out in the open, and a harvest of field rhubarb could be taken. This is what the photograph here shows. In the foreground are tied up bundles of field rhubarb and a lot of loose leaves from harvested stalks. In the background is a line of rhubarb pickers who are producing the bundles shown.
Field rhubarb was used for producing cheap canned rhubarb and for bulking out other canned fruits and especially for bulking out jam e.g. Tickler's jam duing the First World War.
The mill on the right hand side is probably Glen Mills though possibly Tingley Mills. The photograph was taken in May or June 1959. Photograph from the David Atkinson Archive.
