The rhubarb in the photo is a perennial plant with a large rhizome; large leaves sit on long, thick petioles. And he came to Europe only in the 18th century.
Rhubarb belongs to cold-resistant plants.... A shaded place is well tolerated, since it does not need abundant sunlight, but it hates drought. He needs moist soil. Even a slight dryness is badly reflected on the leaf rosette, the leaves are weak, and the petioles lose their juiciness and become coarse and fibrous.
Petioles are used as food for vegetable rhubarb... In terms of taste and nutritional characteristics, they resemble an apple. They contain organic acids, pectin substances, mineral salts and vitamins, which are so beneficial for human health.
Rhubarb in the photo ripens quickly and is ready to eat in May. When there are still so few fruits and vegetables. Compotes, jelly, pie fillings, kvass, juice and wine are made from it.
Traditional medicine uses rhubarb as a diuretic and laxative. Increases appetite, participates in liver cleansing and helps prevent vomiting.
In the same place, rhubarb can grow up to 10 years and give a good harvest of petioles. Plant it in fertile soil with low groundwater. Apply organic fertilizer before planting, 2 - 3 buckets of manure or compost per square meter. In the second year, the plant has uterine stems, which greatly deplete it. They must be removed. Every 3 years, add organic matter at the rate of 1 - 2 buckets per square meter.
Reproduction make by seeds or vegetatively, that is, by dividing the roots.
