What do you need to know about grape pruning?

There are many nuances that are well known to experienced gardeners. For example, why do four kidneys on a branch leave, as well as in reserve on the fruit arrow of about twelve buds? This can be explained by the fact that experienced grapes do everything so that when spring, when they already begin to form, it is easy to choose the best and fruitful branches, and the bad cut. If you leave only about four pieces at once, then you can lose, suddenly something will not succeed, and they will not give the expected result? And so, the specified stock, in some way — reinsurance. The same with the kidneys on the stems, where the flowers are best bloomed, they leave them. Thus, this makes it possible to choose the most optimal and rational option.
