When it blooms, you need to prune the inflorescences. Generally, only 1-2 inflorescences are left on thick fruit branches, and the excess is cut off. Boron fertilizer should also be sprayed before flowering. Once the plant is deficient in boron, it will affect the differentiation of flower buds and reduce the fruit setting rate. Just spray a boron fertilizer solution once or twice before flowering, which is also beneficial to the growth of later fruit. In addition, you should also pay attention to controlling the amount of water after the flowers bloom, and do not water frequently, otherwise it will affect its absorption of nutrients and water, but it will also be detrimental to fruit setting.

1. How to deal with it

1. Thinning the inflorescence: When it blooms, it is necessary to prune the inflorescence, leaving only 1-2 inflorescences on the thick fruit branches, and remove the excess and long thin ones. Cut it off, too much will affect the growth of the fruit later.

2. Spray boron fertilizer: when pollen grains germinate Boron fertilizer should be sprayed. If boron deficiency will affect flower bud differentiation, pollen development will also be affected. Just spray the boron fertilizer solution once or twice before flowering, which can increase the fruit setting rate and improve the yield and quality of the fruit.

3. Control the amount of water: Strictly control the water after flowering. Do not water frequently, otherwise the soil temperature will drop, which will affect its ability to absorb water, nutrients, and moisture, which will also reduce the fruit setting rate. Just add an appropriate amount of water before blooming. After the flowers bloom, don't water until the soil is dry.

2. How to artificially pollinate

Many varieties of grapes do not require manual pollination and can be pollinated by bees or wind. However, some varieties require manual help, otherwise the fruit setting rate will be very low. During pollination, the male and female flower buds can be shaken, and the pollen will fall and spread in the air. Or put on gloves and touch the male buds first, then the female buds, so that the pollen will stick to the female buds, which can help pollination succeed and increase the fruit setting rate.
