Rhubarb is the oldest vegetable crop.
This is a perennial plant with fleshy petioles and basal leaves, forming a thick and large rosette.
Because of the petioles, which rainwater rolls, it got its name: “reos” is translated from the Greek as “flow”.
For the first time rhubarb was introduced to Europe in the Middle Ages, but they began to be eaten only in the 18th century.
Rhubarb can grow up to 20 years in one place, but it is recommended to replant it every 5 years.
The optimum soil type is wet, non-acidic, fertile. In one hole to a depth of about three centimeters placed 6-7 seeds. The rhizomes are planted at 3-4 cm depth.
It makes no sense to harvest the seeds specially: rhubarb is cross-pollinated, so it is recommended to remove the flower stalks so that the plant does not waste additional nutrients.
Rhubarb is popular among gardeners: the crop is one of the first to be harvested, and the plant has many useful properties..
