Cultivation

The cultivation method for forced rhubarb was developed in the early 1800s.
The fields were fertilised with large quantities of horse manure and '
night soil' from the nearby urban areas and woollen waste from "
mungo and
shoddy" mills.
The rhubarb plants spend two years out in the fields without being harvested. While in the fields the plants store energy from the sun in their roots as

. The roots are subjected to frost before being moved into sheds in November where they are kept in complete darkness. In the sheds the plants begin to grow in the warmth and the stored carbohydrate in the roots is transformed into

resulting in forced rhubarb's sour-sweet flavour.
The sheds are long low buildings which are heated; originally with coal, which was plentiful and relatively cheap in the area, but this has been replaced by diesel.
Forced rhubarb grown in the sheds is more tender than that grown outdoors in summer. Without daylight the rhubarb leaves are a green-yellow colour, and the stalks, measuring around , are crimson in colour with a smooth texture. Traditionally, the pickers pull the stalks in candlelight as any exposure to strong light will stop the growth. By the end of March the

History
Growing and forcing rhubarb was originally done by many hundreds of small farmers, smallholders and market gardeners. In later years some growers expanded and owned many thousands of roots and extensive forcing sheds.
In the late 19th century early forced rhubarb was sent to

for the French market. A special express train carrying rhubarb was run by the
Great Northern Railway Company from
Ardsley station every weekday night during the forced rhubarb season from Christmas until Easter. Up to 200 tons of rhubarb sent by up to 200 growers was carried daily at the peak of production before 1939.
In 1962, a rail strike caused the growers to look for alternative transport and the service ended shortly after.
Wakefield Museum has a permanent exhibition about forced rhubarb.
Rhubarb became less popular after the Second World War when more exotic fruits became more available.

EU recognition of Yorkshire forced rhubarb

Twelve farmers who farm within the Rhubarb Triangle applied to have the name "Yorkshire forced rhubarb" added to the list of foods and drinks that have their names legally protected by the European Commission's
Protected Food Name
Three European Union schemes of geographical indications and traditional specialties, known as protected designation of origin (PDO), protected geographical indication (PGI), and traditional specialities guaranteed (TSG), promote and protect nam ...
scheme.
The application was successful and the farmers in the Rhubarb Triangle were awarded Protected Designation of Origin status (PDO) in February 2010. Food protected status accesses European funding to promote the product and legal backing against other products made outside the area using the name. Other protected names include
stilton cheese,
champagne and parma ham. Leeds Central MP,
Hilary Benn, was involved in the Defra campaign to win protected status.
Culture
Wakefield Council holds an annual Rhubarb Festival in February, celebrating the area's links and promoting the surviving rhubarb industry. A Farmers' Market, cookery demonstrations, walks and tours of the forcing sheds are among the attractions.
In 2005 Wakefield council erected a sculpture depicting a rhubarb plant in Holmfield Park Wakefield.
Rhubarb growing and the 'Rhubarb Express' are featured in
Wakefield Museum.
In
Frances Brody's 2019 novel ''The Body on the Train'' (Piatkus: ) a murdered man's body is found on a rhubarb train from Ardsley, on its arrival at
King's Cross. The book's cover illustration features boxes of rhubarb on a platform beside a train.
