What fertilizer to apply before grape vines bloom (when is the best time to apply fertilizer before grapes bloom)

Grapes generally need to go through multiple growth stages before they bloom. Starting from the budding stage, the flower organs, root systems, etc. are growing rapidly. During the budding stage, the grape inflorescence continues to differentiate and requires additional nutrients to supply nutrition .

As new shoots, inflorescences, etc. grow, the grapes will digest the nutrients stored in the plant. When the grapes enter the wound exudation period, pruning too late should be avoided to avoid nutrient loss.

Garden cleaning

In winter, the vineyards can also be cleaned up, mainly to clean up the ones that have escaped the winter cleaning.

It is recommended to remove the dead branches and old bark on the tree in time, and then spray the garden with a cleaning agent before budding. In years with more rain, Bordeaux mixture can be applied to prevent and control diseases.

Germination and fertilization

Germination fertilizer is generally applied when the grape buds begin to swell. This is also the period of continuous differentiation of flower buds. At this time, not only the new shoots grow fast, but also the flower buds grow fast.

A large amount of nutrients are needed during this period. If the root system is not in good condition or is aging, it may affect the root system's nutrient absorption.

Generally, you can apply fertilizer by digging trenches. Generally, compound fertilizer is used for digging trenches for application. You can also use Sea Elf biostimulant and high-nitrogen compound fertilizer or water-soluble fertilizer for application together.

If the tree is in the nutrition process, it is not recommended to use high nitrogen fertilizer. For those with poor root growth, it is necessary to use rooting biostimulants.

If compound fertilizer is applied in the ditch, it is usually mixed with soil and buried, and then covered with soil. If compound fertilizer is applied, it is recommended to irrigate in time after use. If there is a lot of rain, decide how to fertilize according to the situation.

Foliar Fertilization

Some orchards do not apply winter fertilizer or use less organic fertilizer in winter. You can also add biological organic fertilizer or decomposed farmyard manure when fertilizing. It is recommended to add foliar fertilizers such as boron and zinc before flowering, which will help improve the quality of flowering.
