Black finger grapes: description of the raisin variety, planting and cultivation

Seedless grape varieties are especially popular with gardeners for their taste. Not every variety takes root in the domestic climate, but, thanks to the work of breeders, today every summer resident living in the middle lane can grow seedless berries. The Black Finger grape variety is considered the largest of the seedless varieties and has a late ripening period.

On the creation of Black Finger grapes

Kishmish grape variety is popular due to the lack of seeds. However, he also has disadvantages - this is a small size of berries, not exceeding 3 grams by weight.Scientists from the Israeli Center for Heredity and Variation have managed to create a hybrid that does not have seeds and at the same time has a large size.

There is an opinion that biotechnology was used in the development of a new variety. There was also a version that such grapes are a product of genetic engineering.

Description and characteristics

A brief description and characteristics of Black Finger table grapes are as follows:

1. The ripening period is late, 155 days are needed from the moment the vegetation begins to fully ripen.
2. Percentage of sugar content - more than 20.
3. Destination - for human consumption.
4. The average weight of one bunch of grapes is about 1500 grams.
5. Bunch shape - cylindrical, asymmetric.
6. The taste of fruits is harmonious, pleasant, with barely perceptible notes of nutmeg. The skin is firm, but quite edible, and the flesh is sweet and juicy, crispy.
7. The shape and weight of the berries is slightly elongated, about 14 grams.
8. Fruit color - dark purple, almost black.
9. Resistant to cold - withstands temperatures down to -22 degrees.
10. Transportability is high, grapes carry long distances without loss of presentation.

Pros and cons of the variety

Those who have already tried growing Black Finger raisins in their backyards have noted the advantages and disadvantages of the hybrid.

Pros and consHigh yields with proper care and a large weight of clusters.Excellent taste and aroma of berries.Lack of seeds with a large fruit size.Good transportability, which allows you to grow grapes for subsequent sale.The need for shelter in the northern areas.Short shelf life of berries.The impossibility of using grapes for making wine, it is suitable only for fresh consumption.Low resistance to common crop diseases and the need for regular preventive treatments.

Features of growing crops

Kishmish Black Finger grapes were created by breeders for cultivation in a warm Mediterranean climate, so the hybrid is not suitable for cultivation in the northern regions, where there is a significant decrease in temperature in winter. Even in the middle lane, the culture will have to be significantly insulated before the onset of cold weather.

When is the best time to plant

Planting Black Finger grape seedlings is allowed both in spring and early autumn, it all depends on the growing region.In the southern regions, autumn planting is preferred, and in regions with a cool climate, work is carried out in the spring, in which case young bushes will have time to adapt to a new place.

Where to plant on the plot

For planting, plants select a site on a small hill so that groundwater in a rainy summer does not damage the roots of the crop.

It is important that the first half of the day the place is in the sun. They also pay attention that the site is not in drafts, as the heat-loving plant does not tolerate gusts of wind.

How to plant

A week before planting, the selected area is dug up and, if necessary, fertilized. Also be sure to choose the roots of weeds so that they do not subsequently drown out young grape seedlings.

Planting a plant is carried out according to the following algorithm:

1. Dig holes at a distance of 2 meters from each other, width and depth - 100x100 cm.
2. A drainage layer of fine gravel or crushed brick is laid at the bottom of the hole. It will retain moisture and prevent it from spoiling the roots of the culture.
3. The selected soil is mixed with nutrients and half is poured into the hole.
4. The seedling is placed on a small mound of soil and the roots are carefully spread in different directions.
5. After that, sprinkle with the remnants of the earth, lightly tamp and tie to a support.
6. Plentifully water the seedling and spread a layer of mulch around it, consisting of organic materials. It will prevent the evaporation of moisture necessary for full rooting, and will not allow weeds to germinate.

How to care for a variety

Without regular care of the hybrid, it is impossible to harvest a rich harvest. The vine needs to be watered, fertilized and carried out preventive spraying. Also grapes need sanitary and formative pruning.

Irrigation and fertilization

Irrigation is carried out, focusing on the condition of the soil - a dry crust should not be allowed. In hot weather, watering is carried out every 7 days, using about 20 liters of water for each bush. It needs to be warmed up in the sun. If there are prolonged rains, they refuse to irrigate, as excess moisture leads to the development of dangerous fungal diseases, to which the hybrid has weak immunity.

Feeding starts from the second year. In the spring, nitrogen fertilizers are used, and at the end of summer, potash and phosphorus fertilizers are used. The formulations are diluted according to the instructions for use attached to each fertilizer.

How to trim

Growing Black Finger grapes is recommended on trellises. Therefore, at first, for 4 years, a bole is formed to the desired height, and after that fruit-bearing side shoots are distributed in a horizontal plane.

Susceptibility to diseases and pests

The hybrid, bred by Israeli experts, has a weak immunity to fungal pathologies. Carry out preventive spraying of the vine twice a season, using fungicidal preparations. From insects, grapes are affected by spider mites. Acaricide formulations are used to control the pest.

Collection and storage

Since the Black Finger is a late variety, harvesting begins in early November. Berries can be stored in the refrigerator for up to 2 weeks.
