Growing grapes Marinovsky
Main characteristics
The parental pair is the July and Amur grapes. These species have contrasting properties, which led to a high resistance of the crop to frosts down to -30 ° C. It does not need to be covered for the winter, hence the name of the grape - uncovered. Temperature extremes can slow down the ripening rate of the bunches.
Marinovsky grapes are unpretentious to the soil, loves water, but easily tolerates its lack, does not need constant fertilization. The bunches are stored and transported for a long time without damage, the yield is high: up to 10 kg from one bush. The species is winey but is often grown for fresh consumption.
Description of the bush and vine
The bush has a high density of dark green leaves, grows quickly. Due to this property, it is often used for garden decoration. The vine has a high fruitfulness, which often puts stress on the bush.
In order to avoid a decrease in berries in size, gardeners recommend cutting off the shoots, leaving about 5 eyes. This reduces the number of bunches but increases the size of the berries.
Fruit characteristics
The clusters are medium in size, cylindrical in shape, the berries are densely packed. The mass reaches 220-310g. the grapes are small, their diameter is 12 mm. They are round in shape, deep blue in color. The skin is strong, the flesh is rich.
Caloric content is about 650 kcal / kg. Marinovsky grapes are rich in glucose, which is quickly absorbed, helps blood formation, and reduces cholesterol levels. The acidity reaches 5 g per 1 liter.
Landing
According to the description, Marinovsky uncovering grapes are propagated by seedlings, which it is desirable to acquire in proven nurseries, since they are susceptible to disease and there is a risk of buying a sick specimen.
The planting process takes place according to the following scheme:
- Digging a hole of at least 60 × 60 cm for free placement of the roots. Ideally, fertile soil with a medium acidity level is used, but sandy loam will also work. In the case of a high clay content, it is advisable to mix the soil with sand. The procedure is carried out in the fall.
- Application of a layer of organic fertilizers, which is covered with a layer of earth.
- After spring warming (temperature not less than 19 ° C), planting seedlings in pre-prepared depressions. They are sprinkled with earth and tamped.
- Watering each bush with a bucket of warm water if the ground is dry.
The first 2 points include preparing the soil in the fall for direct planting in the spring.
Maturation
Temperature affects the ripening time of berries
The Marinovsky variety has an average late ripening period. The process takes 135 to 150 days.The crop is harvested in the fall, from late September to mid-October. It depends on the air temperature (the higher it is, the faster the fruits will ripen).
Plant care
The variety does not require frequent fertilization. Watering with a lot of water is not necessary due to the lobular roots located close to the ground. Removing excess moisture is also unnecessary.
Prerequisites: timely pruning and periodic disease prevention. Despite the frost resistance, young seedlings need to be covered for the winter.
Cleaning the vineyard
This subspecies grows rapidly, reaching 2 m in height, prone to overload, so it needs to be pruned periodically. This is done in the spring or fall. In the first case, the shoots are cut off and 4 to 6 eyes are left. In the second, about 7 eyes are preserved, since some of them can be damaged by cold weather.
If there is an excess of bunches on the vine, cut off a few so that there are enough nutrients for the ripening of large and sweet berries. For this purpose, young fruit-bearing vines are cut in the summer. At the end of summer, to provide access to the sun's rays, excess live and dried leaves are removed from the lower layers of the bush.
Diseases and pests
The Marinovsky variety is resistant to mildew and gray rot, practically not subject to mechanical damage from birds and insects, thanks to its dense skin. The main threat to the crop can be powdery mildew or powdery mildew disease.
By resorting to the following steps, you can reduce the likelihood of a seedling disease:
- spraying the bushes in early spring with a fungicide ("Azofos", "Skor");
- spraying ground sulfur on leaves, vines and soil around the bush;
- treatment of plants in the fall with a 3-5th solution of copper or iron sulfate.
The disease is fungal and prefers wine grapes. Oidium is not easy to remove: its pathogen dies only at low temperatures, so it is worthwhile to carry out prophylaxis systematically. Inspection, cleaning of dead shoots and leaves will help improve the condition of the seedling.
Conclusion
Marinovsky is a noteworthy open grape that will delight lovers of homemade wine and help visually improve the garden.
