Growing features
Amur white grapes are very easy to care for. Even a beginner can master the cultivation of this variety. Such a plant is cultivated on a level or slightly elevated place, you can plant it near a wall or fence to create a beautiful hedge. The grapes must be illuminated by the sun, only then will its fruits be tasty. Amursky is not planted near fruit trees, since it will quickly begin to braid them.
When growing Amur White, it is very important to loosen the soil in a timely manner, since grapes need a lot of oxygen. This should be done before watering. In addition, the variety will definitely need support. Fruiting shoots are tied up horizontally.
Landing
It is very important to correctly determine the time of planting the Amur White in the ground. Seedlings can be planted in October or April. Spring planting is especially popular with those who propagate grapes by layering. In the fall, it is better to start sowing seeds.
The soil should be medium to low acidity. If the indicators go off scale, lime or ash is added to the soil. Landing will depend on the type of soil.
If the land is sandy, then landing in trenches is practiced. You will need to dig grooves 20 cm deep and 50 cm wide. The walls of the grooves must be reinforced with stone or wood. Then sprouts are planted in the grooves.
In clay and loamy areas, it is recommended to plant grapes in ridges. The site is leveled, holes are made on it with a depth of 60 cm, on the bottom of which drainage must be placed.
Pollination
Most of the Amur white grapes are dioecious, but in rare cases bisexual specimens are also found. Male flowers appear earlier than female flowers. Pollination occurs with the help of insects, and wind plays an important role here.
Pruning
The first year of life, the plant should not be touched so that it can strengthen well. In the second year, the branches are pruned, and the tops are pinched. The pruning procedure is carried out only after antennae and inflorescences appear on the bush. Start trimming the grapes from the bottom.
Amur white experienced gardeners advise growing with a stem. Shoots on perennial branches are removed every season. Pinch the top a couple of days before flowering. During pruning, you can take green cuttings, which are then used for propagation.
Watering
Plants up to three years old need to be watered abundantly, because in the wild, such a vine is usually found near open water sources. The liquid is poured directly under the root, you will need about 6 ten-liter buckets per bush. After watering, the plants are mulched. A week before flowering, the liquid supply is completely stopped, otherwise the harvest will be poor.
Top dressing
Amur white grapes respond well to complex mineral fertilizers. If the plant grows on fertile land, one top dressing per season will be enough.In the case of poor soil, fertilizer is applied three times: in spring, before and after flowering. Important: this variety is not fertilized with organic matter.
Frost resistance and the need for shelter
In mild climates, the vines do not cover the grapes, they already feel great under the snow. The exception is young specimens, as well as cases when the temperature drops too low. In such a situation, the vine is placed on the ground, covered with agrofibre and spruce branches are placed on top. It is necessary to remove such a shelter at a time when temperature changes are no longer expected.
Diseases and pests
Amur white grapes are resistant to diseases such as mildew, oidium, gray rot. However, in conditions of high humidity and with improper agricultural technology, he can still get sick. To prevent this from happening, the gardener needs to regularly thin out the crop, removing all unnecessary, and also carry out preventive treatments with fungicides and insecticides. Works are carried out in autumn and spring.
If a grape is exposed to any disease or insect, this always affects its appearance.
Storage
If the grapes are grown for themselves, they can be kept in the refrigerator for a long time. When cultivated on an industrial scale, cool cellars are often used. The culture can be in them for several weeks. Before storing it, it is important to select rotten and spoiled berries.
