Figure 2: The second stage of formation of sleeves No shoots are allowed to develop in the reserve zone, except if it is necessary to restore the annual vine in case of its damage or death. The excess length of perennial wood in the reserve zone can be used to move the second zone on the sleeve (fruiting zone) at any distance from the place of planting, which allows this method to grow grapes on the roof, pergola, balcony of a high-rise house and other places inaccessible to conventional formation. This is a very important advantage of the method, because thanks to him on a garden plot you can grow dozens of varieties and get hundreds of kilograms of grapes almost without taking up space, so necessary for other crops. If this is not necessary (in commercial cultivation on a trellis), the excess of the reserve zone is rolled up into rings and placed at the base of the bush. The diameter of the rings and the number of turns in the reserve spiral are chosen depending on the total length of the reserve zone at this time, so that the base of one-year growth is at the beginning of the left or right parts of the arms development at the height of the first trellis wire. From the base of the one-year shoot on the sleeve and up to about half of its length, the second zone or fruiting zone is distinguished. This part of the annual shoot is tied strictly horizontally to the first wire of the trellis. Its size regulates the load on the sleeve. Formation of fruiting shoots in this zone is carried out according to the technology of traditional formations, regulating their habitus and rationing, if necessary, the amount of yield on each shoot. Up to 6 years of age, removal of fruit-bearing shoots from the second zone (fruiting) is carried out in stages, half in autumn, and the other half after limiting formation in early next summer and gradually, as shoots grow back in the fruiting and growth zones of the next year. Starting from the 7th year after planting, it is possible to remove all fruit-bearing shoots in the fruiting zone from autumn. This becomes possible because the sleeve becomes long enough, and the removed shoots will no longer constitute such a significant part of the above-ground crown already present in the grape plant, and therefore there will be no depression of its root system next spring. Further, on the one-year shoot, the third zone or stimulation zone is distinguished on its second half. All appearing shoots are to be removed on it. It is started after completion of weeping (shoots of this zone allow to fulfill its first task at the beginning of vegetation - to increase the number of sugar consumption points from roots, and after passing the critical period for the root system, they should be removed). Regular and complete removal of shoots allows to successfully solve the second task of this zone - to create a large stock of plastic substances, for very intensive development of the latter on the sleeve - the growth zone. The shoot length of the stimulation zone is used to transfer the position of the vine from horizontal to vertical, but slightly away from the place of development of fruiting shoots. If length allows, it is better to curl the shoot of this zone in a ring. And the last one on the annual vine is the fourth zone or growth zone. At the beginning of the period, it is only one well-developed terminal shoot of our sleeve continuation.
