Keys to budbreak and flowering of the vineyard

The vineyard is part of the history of Spain, achieving a very high quality with denomination of origin and very good valuation worldwide. Climatic factors, soil type and management of our farmers make the Spanish wine one of the most desired.

The spring months of April and May awaken the vines, where buds and stems begin to emerge that will dress the vines prior to flowering. This stage is quite delicate from the climatological point of view, since late frosts can cause the loss of almost the entire future harvest.

At the nutritional level, this is a very sensitive stage, where it is necessary to supply nutrients lost in the previous harvest so that the crop can reach flowering and bunch set with sufficient energy.

In this article we give you some keys for the budding and flowering of the vine to meet the energy demand.

The most important nutrients during budbreak and flowering of vines

From budbreak onwards, the consumption of the main nutrients consumed by the vine shoots up, especially phosphorus content. Just between the period when the buds emerge and the first bunches appear, the consumption of this nutrient reaches its maximum, so it is important to have a soil fertilization (liquid or solid) rich in phosphorus.

Both nitrogen and phosphorus maintain a progressively increasing consumption, reaching the maximum demand that occurs during the first stages of fruit fattening.

However, in order to generate a good initial bud break in the vineyard, the homework must have been done in the previous season, recovering nitrogen, phosphorus and potassium reserves and ensuring a good supply of microelements (boron, zinc and manganese, in particular) to regulate the plant's physiology.

Nitrogen: the stage of greatest requirement in the vineyard coincides with the formation of shoots, flowering and initial fruit fattening, increasing its need progressively.
Phosphorus: the absorption of this element is at its maximum during sprouting until flowering, with a gradual reduction in its need from fruit set, fattening and veraison onwards.
Potassium: the demand for this element increases until the maximum peak that occurs during fruit set and the first stages of fattening. From this point on, and contrary to popular belief, the needs are progressively reduced until the final harvest.
Calcium: should be provided constantly throughout the period, especially in the early stages. It has been shown that late applications of calcium prevent the appearance of diseases and increase the aromas in the wine.
Magnesium: it is constantly supplied to the crop, being in charge of giving greenness to the crop and promoting the production of sugars.

Stimulants for sprouting and flowering of vines

Another of the keys to sprouting and flowering in the vineyard are stimulants. In addition to having an adequate nutritional base with fertilizers prior to sprouting and root movement, there are biostimulant and corrective products whose use promotes a greater energetic contribution to the crop, favoring greater sprouting and higher quality bunches.

During sprouting and flowering, the application of the following products is recommended:

AUGEO: liquid concentrate of Ecklonia maxima seaweed with a high auxin and cytokinin ratio. Creates a physiological stimulus that promotes sprouting and cell differentiation.

QUELATIO: micronutrients concentrate (Cu, B, Fe, Mn, Mo, Zn) with an optimal ratio for vines in the early stages. It prevents any physiopathology related to the lack of microelements, such as chlorosis.

CELERIS: liquid calcium and boron concentrate with physiological cell division promoters. Calcium and boron promote the creation and mobility of auxins, improving sprouting and flowering processes and increasing crop yield.

Seaweed extract (Augeo). Provides an ideal phytohormone ratio in auxins and cytokinins to stimulate the production of new roots.

Nutrients (Quelatio). Maintains an ideal and stable ratio of micronutrients, exactly what the plant needs to maintain the best balance and behavior of the elements.

Calcium (Celeris). Increases the number of flowers and fruit set, as well as guarantees fruit or leaf fattening and quality, preventing physiopathologies related to calcium deficiency.
