What fertilizer is good for grapes?

Overview of grape fertilization

Grapes are deciduous vines belonging to the genus Vitis in the family Vitaceae. They are light-loving and suitable for a wide range of planting, but are more suitable for planting in areas with low precipitation, watering conditions and deep soil. They are more cold-resistant and drought-resistant.

Grapes need a lot of nutrients before they sprout, especially nitrogen fertilizers. If the vineyard is well-fertilized with organic fertilizers and the trees are strong, there is no need to apply germination fertilizers.

What fertilizer is good for grapes?

Grapes require a large amount of potassium throughout their entire growth period. Under general production conditions, the ratio of nitrogen, phosphorus and potassium required by grapes is 1:0.5:1.2.

Generally, organic fertilizer is the main basal fertilizer applied in autumn. The specific amount of fertilizer should be considered according to the actual situation, and phosphorus and potassium fertilizers such as urea, superphosphate, potassium sulfate and other chemical fertilizers should be applied in combination.

How to fertilize grapes to make them grow faster

When fertilizing grape vines in spring, it is best to choose a sunny day. Do not fertilize on rainy days, as this will easily cause the fertilizer to flow away with the rain.

Fertilization in spring : Spring is the stage of vigorous growth of grapes, so it needs to be heavily fertilized, with nitrogen fertilizer being the main fertilizer in the early stage. In addition, some urea can be applied when the grape flower buds are differentiating.

Summer fertilization : Grapes grow rapidly after entering summer, so they should be topdressed with nitrogen fertilizer as the main fertilizer and phosphorus and potassium fertilizer as the auxiliary fertilizers in time. They can be applied deeply in a ring or trench shape, and then covered with soil and watered.

Key points for grape fertilization

1. If you only drip fertilizer without dripping water when planting grapes, the fertilizer in the soil will accumulate and burn the roots of the grapes. Therefore, you need to add clean water before and after dripping fertilizer so that the fertilizer will be fully dissolved, which is beneficial for the roots to absorb nutrients.

2. When the leaves of the grapes turn yellow, if it is caused by improper fertilization, you need to water them more to dilute the nutrients. If the leaves turn yellow due to the lack of nutrients in the soil, appropriate fertilization is needed.

3. Grapes are light-loving tree species. When there is insufficient light, the new shoots are thin and weak, and it is difficult to form flower buds. After fertilizing the plant, it needs to be given appropriate light to facilitate the growth of the root system.
