What is the best fertilizer for grape trees?

Fertilizing time for grape trees

Normally, fertilizer can be applied when the leaves of young grape trees grow to 8-10 leaves. After that, fertilizing the grape trees is usually carried out simultaneously with watering or rainfall. Potassium fertilizer needs to be applied twice after August.

What fertilizer to use for grape trees

It is generally more appropriate to apply urea to fertilize young grape trees, which can promote the luxuriant growth of the branches and leaves of the plants. In addition, when the plants grow taller, it is better to apply phosphorus and potassium fertilizers to them. Fertilization can promote better flowering and fruiting of the plants, ensuring high and stable yields in the following year. Base fertilizer should be applied after the grapes are harvested.

Fertilization method for grape trees

There are two main ways to fertilize grape trees. One is root topdressing, and the other is foliar spraying. Usually, root fertilization is mainly based on the application of quick-acting fertilizers. Dig a trench near the root end of the plant, and then bury the fertilizer mixed with soil in the trench, and then tamp it down and water it.

If you want to spray fertilizer on the leaves of grape trees, you need to dissolve the fertilizer in water first, and then spray it evenly on the plants at a certain concentration. This way, the fertilizer liquid will penetrate into the plant through the leaves, tender shoots, etc.
