Time and method of fertilizing grapes

1. Before germination

When the plants just start to sprout and swell in early spring, you can apply some quick-acting nitrogen fertilizer. Just apply the fertilizer near the roots. The roots can absorb it, which can promote the newly grown shoots to become strong and can also help increase the yield. Fertilization is very critical at this time.

2. Before flowering

Fertilization can be done two weeks before flowering. At this stage, the main fertilization is foliar fertilization. After preparing the medicine, spray it on the leaves. The main type of fertilizer is boron fertilizer, and some microbial sweeteners can also be selected. The effect of fertilization at this time is still quite significant. It can improve the progress of photosynthesis and transform substances. It has a good effect on later flowering, fertilization, fruit setting, etc.

3. Young fruit stage

After the flowers have faded, when the young fruits are just beginning to swell, topdressing can be done, mainly with nitrogen fertilizer, which can also be combined with potassium and phosphorus fertilizers. The fertilization method should be combined with tilling the soil. First, turn the soil deeply, and then bury the fertilizer in a small hole about 30-50 cm away from the plant.

4. Berry Ripening Period

When the fruit begins to turn color, it is also an important time to apply fertilizer, mainly fertilizers containing potassium and calcium. The method of fertilization is not only to apply it to the roots, but also to spray it on the leaves.
