Features of minting grapes
Some procedures used by gardeners in the care of the vine have an ambiguous reputation among practitioners. These include the chasing of grapes. It is designed to improve plant productivity and protect it from standard problems. The expediency of the procedure is determined by the conditions of growth of the grapes and by the gardener himself.

Features of minting grapes
The summer minting of grapes consists in the removal of the upper parts of the shoots of the vine. Stems grown on the main perennial trunk, on replacing branches and fruit shoots lend themselves to such a procedure. Unlike pinching, branches are more authentic to this procedure, the removed part is much larger.
The benefits of minting grapes are as follows:
- redistributed the influx of nutrients to clusters and sleeping kidneys;
- improves airing of the bush and sun lighting of fruits;
- the vine is protected from fungal infections and putrefactive formations;
- young shoots ripen faster and prepare for wintering.
Most often minted grapes with an average ripening period: it is able to accumulate an excessive amount of green mass. Leaves consume many useful substances, slowing down the accumulation of sugars by berries, because their ripening is sometimes delayed before the onset of cold weather. Early grape varieties are rarely minted: they manage to produce a full-fledged crop faster.
Dates of the procedure
The embossing of vines begins in the period of slowing down the main growth of young shoots. A kind of signal to the beginning of the procedure is the straightening of the top of the vine. At the stage of active growth, the branches bend down, because one side of the stem is stronger, develops faster. When the development of the abdominal and dorsal sides is aligned, the shoot acquires the correct position.
For each grade, this manipulation has certain deadlines:
- for early varieties - late July-early August;
- for mid-season and late - mid-August.
Special minting dates for plants that are cultivated in greenhouses or greenhouses. Pruning of branches above 1 m of growth is carried out in July, if necessary. Subsequently, the branches are shortened at the end of August and in October to densify the tree trunk.
Stages of coinage
The procedure contributes to the early ripening of berries.
The grapes are minted in the summer by secateurs. During the process, the tops of shoots that have 16-18 leaves along the entire length are removed. The removed part should contain 4-6 leaves, their number depends on the total on the stem. The main condition is to leave at least 10-12 leaf blades above the upper bunch. Above the clusters in some vines, another 2-3 leaves are nibbled until they ripen. This helps to improve the color of the berries and contributes to their early ripening.
10-14 days after the procedure, the active growth of stepchildren begins.
They provide an accumulation of juices for the development of sleeping buds, from which inflorescences will appear next year. If pruning is done too early, stepsons increase too quickly in growth and use the plant's reserve for the winter. Such growth processes can induce early blooming of sleeping buds, which will weaken the vine and lead to a reduction in fruit ovaries in the next growing season.
In order to control the growth of the stepsons, pinch as soon as 4-6 ripe leaflets appear. They make sure that 2-3 leaves are left on each. In such quantities, they help the grapes to produce a sufficient amount of nutrients and preserve sleeping buds to form ovaries in the spring.
For some vigorous species, the chasing of grape shoots is carried out 3-4 times during the period of active vegetation. The first passes before flowering, when up to 13 leaves are left on each shoot. The following affect only stepsons growing from a pair of upper buds to a height of 5-6 cm. The same actions are necessary when caring for irrigated plants: their growth rate exceeds the ability to accumulate useful substances. Shortening the branches of grape varieties with a fast growth rate will improve the ripening of berries and shoots by autumn.
After the procedure, all branches, leaves and buds are taken out of the site and burned. This prevents the development of diseases and the transition of infections to healthy plants. If the vine was not infected, the resulting ash can be fertilized with other garden trees and shrubs, as well as the grapes themselves.
Pruning does not always positively affect the yield and well-being of the vine. There are some contraindications for this operation. The minting of grape bushes is not carried out when:
- grapes grow in regions with hot summers: a similar effect leads to superficial burns of leaves and delicate clusters;
- the variety of berries belongs to wine, not table - this grape is small and does not have excess green mass;
- the free vine grows on a gazebo, arch or veranda - it does not need chasing, because it has stronger stems, it is better lit by the sun, and it brings a good harvest;
- a kind of pruning of young grapes will not give the expected results: its vines are not ripe enough and have a small reserve of nutrients for the winter;
- the bush is weakened by illness or mechanical damage, it does not have enough strength to recover;
- Dry summers are combined with pest attacks.
The process of minting grape shoots is a useful, but optional step in the process of caring for the vine. It is carried out mainly in the summer to help the plant cope with the ripening of the fruit and for preventive purposes against diseases such as mildew and gray rot. This manipulation has its own characteristics, and therefore its need should come from the grape variety, weather conditions and the physical condition of the bush itself.
