Grape cultivation: watering
In the cultivation of grapes, the watering operations take on fundamental importance. Very little water intake, as well as excessive water, negatively affects the development of the plant and, consequently, of the fruit. It is very important to be able to understand when the plant really needs water, so as to proceed with irrigation only when needed. Too little water is practically useless because it would not be able to reach the roots deeply or evaporate immediately. Generally, 25 l per plant represents a correct amount (in full ground). You must never overdo it because high water doses greatly stress the plant with very serious consequences. Watering can be done safely every 8-10 days.
How to grow the grape plant
Although the best cultivation for grapes is that in open ground, it is not impossible to grow them in pots with good satisfaction. The dimensions of the pot are very important and must have a diameter of at least 50 cm. The roots of the vine, in fact, absolutely need a lot of space. The higher the latter, the better the results in cultivation. Where there is a mild climate, the plants are carried out at the beginning of the winter season. Where it is colder, however, it is advisable to wait for the end of winter. However, this operation is carried out exclusively during the vegetative rest. The soil used must be very rich in highly mature manure to which a little pumice must be added to obtain a truly draining soil, a condition that is indispensable for the vine.
Fertilization of the vine
The vine plant must absolutely be entertained in the correct way to avoid the risk of any diseases as much as possible. Fertilization is certainly one of the inevitable operations, to be carried out scrupulously. Before winter it is, first of all, necessary to integrate the substances in the soil with good quantities of mature manure. If necessary, it will be necessary to intervene in the same way also subsequently, after the eventual formation of the fruits. It is certain that absolutely must not exceed because too much nutrition does not correspond to an improved production. Calcium and potassium are the essential elements for the vine. Nitrogen and phosphorus are also important, but less. The fertilizer must be lightly buried and made to penetrate the soil with a light watering. Green manure of legumes is perfect.
Grapes: Exposing the possible diseases of the vine
The vine is a plant with very few pretensions. To obtain a good grape, an indispensable factor is the exposure of the plant. This must absolutely be in perfectly sunny ground. The sun, in fact, positively influences the life of the plant and also the flavor of its fruits. However, neither the shaded areas nor those in which there is excessive air humidity are not good at all. Proper ventilation is also essential. The vine is a plant that unfortunately is very often the victim of diseases or parasites. Among the most frequent diseases, the so-called "downy mildew" and "botrytis" are mentioned. Both result from excessive water intake. They fight with special chemicals. Among the parasites, one of the worst is the "red spider", characterized by its very high infesting power, which must also be chemically eliminated.
