It is better to plant the seedling away from other crops: grapes do not like the neighborhood of fruit trees. You cannot plant a seedling in the shade or in a draft - in such conditions, the culture will not grow properly, and the harvest will be weak. The planting of grapes is planned at the beginning or end of the growing season.
Landing in the soil
The planting pit is prepared a month before planting the seedling. The optimum depth for the hole is 90 cm (this depth is enough for a large root system of grapes to grow). As fertilizer for the planting pit, compost or ordinary manure diluted with water is used.
If several seedlings are planted at once, there should be a distance of at least 3-4 m between them. After immersion in the hole, the seedling is covered with soil, which is rammed. The young shoot is watered (at least 5-10 liters of water are used).The water is preheated in the sun. Additionally, a support is installed - it will allow the seedling to grow up correctly. The height of such a support is at least 1.5 m. After planting, for the first month, the bush is watered abundantly, and then the irrigation and fertilization regime is established.
Plant care
When growing Korinka Russian, watering, fertilization of the soil and pruning of excess vines are organized. Abundant watering is needed during the warm season. The warmer it is outside, the more moisture is introduced. The soil is fertilized no more than once a season. Do not apply too much organic or mineral fertilizers.
For the rapid growth of Korinka Russian, trimming of excess lashes is needed. Broken branches are pruned as needed: the main procedure is carried out in early spring before fruit formation. Diseased branches are cut, which can cause illness of the entire bush. The cut site is treated with a disinfectant solution.
Once a season, the soil is loosened: such measures can improve the throughput of the soil, and increase the efficiency of irrigation. Loosening helps to get rid of the spores of the fungus, which can be stored in the ground. For a frost-resistant crop, no shelter is made for the winter: as soon as the processes in the bush slow down, watering and fertilization of the soil stops.
