When is the best time to fertilize grapevines
Summary: This article discusses the best time to fertilize grapevines, providing information on when and how to fertilize grapevines for optimal growth. This information will certainly be helpful to you, so let's take a look together!
1. Fertilizing during the germination period. Clear the fertilization trench 5-10 days before the beginning of spring, and start fertilizing after the spring equinox. Make a trench 30-40 cm away from the root to apply fertilizer, which is very beneficial for the growth of the grapevine plant and its branches and leaves. About 10 days after germination, pinch the tips to adjust the nutritional structure and prepare for bud formation.
2. Fertilizing during the fruiting period. Spray a 0.3% borax solution 15 days before flowering to increase the fruit setting rate. After fruit setting, apply phosphorus, potassium, and nitrogen fertilizers in small, frequent doses, which is very helpful for fruit growth. Thin out dense fruits to reduce the burden on fruiting branches, as too many fruits can result in small fruit size and affect quality.
3. Fertilizing during the expansion period. Fertilize according to the needs of the grapevine's growth and development, with different types of fertilizers for different growth stages. During the period when the grape fruits gradually expand, apply foliar fertilizers mainly, supplemented with some trace elements like calcium and boron to make the fruits larger and prevent splitting.
The above is the related explanation of when is the best time to fertilize grapevines and the optimal fertilization time for grapevines. I hope it brings a little help to your life!
