Reproduction of this plant can be done in several ways, namely by dividing the rhizomes and seeds.
Planting rhubarb in any way requires careful soil preparation. For planting rhubarb, you must choose a place that is characterized by the absence of stagnant water. It is best to plant the plant on light loam.
Also rhubarb is suitable for other soil, which is richly fertilized with humus. Before planting a plant, humus must be added to the soil at the rate of 10 kilograms per square meter.
Also, before planting rhubarb, the soil must be fertilized with minerals in the amount of 100 grams of fertilizer per square meter of soil. Before planting this plant, the soil is cultivated to a depth of 40 centimeters.
In order to reproduce the plant in a vegetative way, it is necessary to dig out the rhubarb bushes. This action is performed in early spring. The rhizomes of the plant are divided into parts using a knife. Each part of the rhizome should have at least 2-3 growth buds with a root.
If you dig up an old plant, you can get from 5 to 10 planting roots. After separating the rhizomes, they must be planted immediately.
When planting rhubarb seeds, they must be initially soaked in water until they swell completely. Germination of seeds is carried out under moistened gauze or burlap. This material is folded in several layers and spread on a flat dish or other surface.
From time to time it is necessary to moisturize the fabric with water. When the first sprouts appear, 1-2 millimeters long, the seeds must be dried and planted in the ground.
The seeds are planted in a pre-moistened soil. After sowing, the seeds will sprout in 4-5 days. This procedure must be carried out at the end of April or at the beginning of May.
Seed planting is carried out in rows, the distance between which must be at least 25 centimeters. The planting depth is 2-3 centimeters. After the formation of three leaves at the seedlings, it is necessary to thin them out. The distance between plants in a row should be at least 20 centimeters.
Features of plant care
To ensure the full growth and development of rhubarb, he needs to provide complete care, which consists in:
- Top dressing;
Weeding this plant should be done regularly. This will not only get rid of weeds, but also significantly improve the quality of rhubarb growth. It is necessary to water the plant as the soil dries up. Rhubarb is very fond of moisture, but you should not overdo it with watering, otherwise the plant may rot.
It is best to use slurry to fertilize the plant. It must be diluted with water at a concentration of 1: 5. Humus should be applied under rhubarb once every 3 years. For fertilization, you need to take 4-5 kilograms of humus per square meter of land on which rhubarb is planted.
The depletion of the plant is carried out in the presence of flowering shoots, which is why they must be removed in time. This action is performed at the very base of the peduncle. In this case, you do not need to leave hemp through which water can enter, which will lead to root rot.
The plant can be damaged by cabbage and potato scoops. These pests on the stalk of rhubarb make moves and damage the rhizomes. Also rhubarb can be damaged by aphids. In this case, the leaves of plants shrivel and curl, which leads to their growth retardation. The sorrel beetle can also damage rhubarb leaves by making holes in them.
This plant can also be attacked by the common heartworm. This is a butterfly, which has wings in a span, 33-42 centimeters long. In the spring, caterpillars appear that damage the stems of rhubarb. As a result, the stems are damaged and break off. Damaged plants dry up, and the pest moves on to new ones.
If left unchecked, the heartworm can destroy large plantations of rhubarb. To destroy the pest, it is necessary to cut off the damaged rhubarb leaves, as well as destroy the weeds, since the females lay eggs in them.
The rhubarb weevil is a beetle that is 4-6 millimeters long. It damages the plant, causing it to dry out. The rhubarb weevil eats the leaves of the plant in the spring. Chemical preparations cannot be used to combat this pest.
This is because the leaves are used for food. That is why rhubarb is processed before and after flowering. Also, in order to combat this insect, plants damaged by it can be removed.
Rhubarb is a fairly unpretentious plant, which greatly facilitates the process of its cultivation. In this case, it is necessary to ensure that the plant is not damaged by pests, otherwise it will not be suitable for food.
