From the proper pruning of the grapes, its growth, the formation of the fruit, and the quantity and quality of the harvest obtained directly depend on it. If the bush is not cut off, a lot of shoots and flowers will appear in time.
Due to the large number of vines and leaves, sunlight will hardly penetrate. In addition, the inflorescence will not be pollinated badly. Because of this, grapes are formed too small and loose. In this case, the fruits will decrease in size.
Timely removal of excess shoots can contribute to obtaining a greater yield. At the same time, the taste qualities of fruits and their size will change for the better. Also, this procedure will greatly simplify the care of the plant. If you do not engage in the formation of a bush, it randomly grows in all directions.
Adult grapes, which are harvested for the winter, it is recommended to prune in autumn. Because of this, hiding a bush will be much easier and it will be better protected from low temperatures. In addition, care for such grapes in the spring will not cause unnecessary trouble.
Do not prune the vines in the spring. If this is done during the sap flow, “tears” will form on the branches. This can be detrimental to both the harvest and the general condition of the grapes.
With the onset of spring, when the air temperature does not fall below +5 degrees, you can carefully trim the young shrubs that have not yet begun to bear fruit. You can also cut off the seedlings that were planted in the fall soil.
In fact, summer pruning is not involved. During this period pluck on the plant unnecessary shoots, as well as perform pasynkovanie and remove excess branches. Such actions are aimed at combating certain diseases that a plant can suffer. Thanks to this, the bush will be better ventilated, and the sun’s rays will be directed to the ripening bunches.
In addition, due to timely and competent removal of excess shoots, the influx of nutrients to the bunches will increase. You can also cut some leaves.
Nuances of pruning
Experienced specialists recommend leaving a few kidneys on the knot. Approximately 4 will be enough. On the fruit arrow it is necessary to leave about 11-13 kidneys. There are several explanations for this method.
Mostly this is done in order to hedge for the winter. Since, with the onset of spring, the remaining buds that are on the substitutional knot will allow you to select those processes on which the largest inflorescences were formed. The remaining shoots can be removed.
If the grapes grow in the northern regions, then on the fruit arrow the first few kidneys can be unfruitful. Because they begin to form in the beginning of summer, when the weather is still cool and they do not have enough solar heat.
In this case, up to the seventh kidney, inflorescences of medium size can form. The remaining eyes should give large inflorescences. Since they begin to develop in July, the weather at this time is the most acceptable.
Pruning for increased yield:
1. In early September, it is necessary to get rid of the young shoots that formed on the first 50 centimeters of the perennial sleeve;
2. on shoots that have grown higher it is worth cutting off the tops and removing all stepsons;
3. After the leaves are all fallen off, it is necessary to select two well-developed shoots at a height of up to 80 centimeters above the ground;
4. Then you can proceed to the formation of a bough replacement, for this you need the lowest process, which was formed on the sleeve to cut to 3-4 kidneys;
5. The second shoot should be cut, leaving 5-13 eyes, it will become a fruit arrow, while you need to leave a few more kidneys, in case the grapes freeze.
