Rhubarb is grown in the Netherlands almost all year round.
Gardening
Dutch farmers cultivate rhubarb outdoors in summer and in closed greenhouses in winter.
This is reported by the Planter magazine.
“In the open field, the crop is harvested from April to September,” the article says. "Outdoor rhubarb forms a bush with powerful stems and huge leaves."
In closed greenhouses, rhubarb stalks are harvested for sale from November to the end of March.
“Forced rhubarb from closed greenhouses is in high demand and is used to prepare a wide variety of dishes in restaurants and food service establishments,” the publication says. - The price of rhubarb from closed greenhouses is much higher than that of rhubarb from open ground, since production volumes are much lower. In general, 8 to 10 tons of forced rhubarb is obtained from an area of 1 hectare during 12 weeks of the total harvesting period, depending on the variety. From January to the end of March, prices average 3 euros per kilo. The Netherlands even exports rhubarb to Japan, where it is also in demand among gourmets. "
