What fertilizer is good for grape vines?

Overview of Grapevine Fertilization

Grapevines are plants of the genus Vitis in the family Vitaceae. They are suitable for growing in fertile land that is well-ventilated, sunny and well-drained. They require more water in the early stages of growth or during the vegetative growth period. During the normal growth period, they need a certain intensity of light to ensure their normal growth.

Generally speaking, if you want to fertilize grape vines, you can apply farmyard manure, organic fertilizer, or fermented farmyard manure. These are high-quality base fertilizers for grape vines. These fertilizers have a relatively long fertilizer effect, mild fertilizer effect, and more comprehensive nutrients, which can provide sufficient nutrients for the growth of the plants.

What fertilizer is good for grape vines?

Normally, different fertilizers need to be applied to grape vines at different times. It is better to apply organic fertilizer and inorganic fertilizer 5-10 days before the beginning of spring. The combination of the two can promote plant germination. The specific fertilizers applied are manure, urea, calcium sulfate, potassium sulfate, zinc sulfate, boric fertilizer and ferrous sulfate.

After the plant sprouts, if the branches grow weakly or sprout unevenly, you need to apply urea, calcium sulfate and potassium sulfate to fertilize and strengthen the branches.

How to fertilize grape vines to make them grow faster

The method of fertilizing grape vines is relatively simple. Just dig a ditch on both sides of the grape vines, apply the prepared organic fertilizer, then fill it and water it.

When digging trenches and applying fertilizer to grape vines, be careful not to dig trenches in the same location every time you apply fertilizer, as this will damage the newly grown roots from the previous year.

1. Fertilization in spring

Spring fertilization is generally carried out around April. At this time, nitrogen is one of the nutrients that grapevines require in larger quantities, so it is necessary to apply nitrogen-containing fertilizers to the plants in time to promote vigorous growth.

2. Fertilization in summer

In summer, fertilizer is generally applied from June to July. At this time, the grape vines have a relatively high demand for phosphorus, so fertilizers containing phosphorus need to be applied to them to promote the enlargement of the grapes.

3. Fertilize in autumn

It is more appropriate to apply fertilizer in mid-October in autumn. At this time, the grapevines need a certain amount of potassium, so it is necessary to apply fertilizer containing potassium to give the plants sufficient nutrients to resume growth.

4. Fertilize in winter

It is more appropriate to apply fertilizer in November and December in winter, and the fertilizer should mainly be decomposed human feces or urea, wood ash and other quick-acting fertilizers.

Key points to note when fertilizing grapevines

In order to prevent fertilizer damage and root burn when fertilizing grape vines, you should not use too concentrated fertilizers, and the amount applied should not be too much.

To prevent the leaves of the grape vines from turning yellow, it is necessary to use a combination of inorganic fertilizers and organic fertilizers, and a combination of chemical fertilizers and microbial fertilizers to achieve full nutrient fertilization, which can prevent the leaves from turning yellow.

Grapes are light-loving plants with high requirements for light, so after fertilizing, it is necessary to ensure sufficient light to promote the growth and development of the grape vines, and to increase yield and quality.
