Rhubarb is a fairly common perennial herb with a powerful root system and very large fleshy leaves that sit on thick petioles.
Varietal features and good care allow you to grow rhubarb, the petiole part of which reaches a mass of one kilogram. In our country, several species of this culture are grown with green or red petioles. The color scheme varies in intensity.
Rhubarb belongs to cold-resistant plants and in our climatic conditions not only grows well, but also hibernates without shelters and gives a stable and high yield. Plant care is practically not required.
However, it must be borne in mind that the lack of water and high temperature indicators prevent the leaf outlet from developing fully, and the quality of the edible petioles is greatly reduced. They become coarse and not juicy enough, their fiberiness increases.
Description of varieties
In summer cottages and household plots, it is recommended to grow several varieties of rhubarb at once. A good option is the cultivation of species with different ripening periods, as well as different colors. Of green petioles, mashed potatoes are most often prepared; with their use, very tasty and vitamin green cabbage soup are obtained. It is advisable to use red-hot plants for cooking compote, jelly or in the manufacture of filling for pies.
The following varieties are considered the most popular and fruitful:
- Moscow-42 - A very early variety with high productivity and excellent taste. The length of the petioles is not more than 70 centimeters, and their thickness does not exceed 3 centimeters. Petioles are smooth, green, with a red stripe near the base.
- "Victoria" - early and fruitful variety. The flavoring qualities of rhubarb of this variety are excellent, which makes its use universal. The length of the petiole is a little over 60 centimeters. The disadvantage of the variety is abundant flowering.
- Tukumsky-5 - A very early and productive variety, characterized by a wonderful taste of rounded and juicy petioles. The length of the petiole is about 70 centimeters, and the average weight of one petiole can reach 150 grams.
- Ogrsky-13 refers to mid-ripening and high-yielding varieties. It grows well and forms petioles in shading. The pulp of long and thick petioles is very juicy and tender. A pair of generative shoots forms on the plant.
How to care for rhubarb
Rhubarb can be propagated vegetatively or by seed. The first option involves dividing the bush, whose age is no more than five years. You can not carry out vegetative propagation of the plant at the flowering stage.
Bush division performed in spring or early fall, before the first frost. A bush dug from the soil should be divided into several parts. A healthy root with a pair of large apical buds is suitable for planting. In the process of planting, the kidneys should be buried no more than one and a half centimeters.
Plant propagation by seeds involves soaking them four days before sowing for a period of not more than ten hours. To get seeds from their own plants, one of the three-year-old plants should leave one of the most developed and powerful peduncle. After the inflorescences acquire a brown color, the seeds must be collected and dried.
Care and feeding
Rhubarb is very unpretentious and tolerates minor errors of agricultural technology. Plant care is simple and consists of the following activities:
- loosening of soil around the bushes in the spring, after the snow melts and the soil warms up;
- the soil for planting rhubarb has been dug up since the autumn, the digging depth should be about 30 centimeters;
- timely harvesting a year after planting with breaking out, rather than trimming, the petiole;
- for longer storage on broken petioles, it is necessary to leave about five centimeters of the leaf part;
- when steadily frosty days occur, the entire aerial part of the plant is subject to cutting.
Standard plant care includes top dressing in compliance with the following basic requirements:
- for every square meter of planting, at least 8 kilograms of organic fertilizers should be applied, which is recommended to use peat compost or manure;
- care of the plant in the spring involves digging and making 30 grams of ammonium nitrate, which is supplemented by superphosphate and potassium salt;
- each season, it is necessary to feed the rhubarb once with the following composition: a little more than a teaspoon of urea, a tablespoon of nitrophoska and 500 grams of mullein should be added to a bucket of water.
The main area of nutrition, which should be provided to the culture for full growth, is about a square meter per bush. Despite the fact that caring for the plant is minimal, some features of the culture should be taken into account:
- although the plant is shade tolerant, it prefers sufficiently lighted areas for planting;
- young rhubarb bushes are characterized by special sensitivity to lighting;
- rhubarb is best when grown on loamy areas and moisture-intensive soils enriched with organic matter;
- Rhubarb is a water-loving plant and during drought requires watering at least once a week in the amount of at least 15 liters of water per square meter.

Diseases and Pests
Like any cultivated plant grown in household plots, rhubarb is prone to some problems associated with plant damage by pests and diseases. The category of the most common and capable of causing maximum harm to the plant includes diseases such as white spotting, rust, and downy mildew.
Most often, the use of strong chemicals to combat the defeat is not required. Folk remedies have sufficient effectiveness. A good result can be achieved through a mixed planting of rhubarb with onions and garlic, which protect the crop.
It should be remembered that rhubarb should not be harvested from mid-summer. This is due to the accumulation in the petiole of oxalic acid, which in excessive amounts is not a useful substance for humans.
