Rhubarb is the oldest vegetable crop.
It is a perennial plant with fleshy petioles and basal leaves forming a dense and large rosette.
Because of the petioles, along which the rainwater rolls down, it got its name: "rheos" is translated from Greek as "to flow".
For the first time, rhubarb was introduced to Europe in the Middle Ages, but 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 optimal type of soil is moist, non-acidic, fertile. 6-7 seeds are placed in one hole to a depth of about three centimeters. Rhizomes are planted at 3-4 cm depth.
It makes no sense to specially harvest the seeds: the rhubarb is cross-pollinated, so it is recommended to remove the peduncles so that the plant does not waste additional nutrients.
Rhubarb is popular among gardeners: the harvest is one of the first, and the plant has many useful properties.
