2. How to manage

Many varieties of grapes do not require manual pollination and are pollinated by wind or bees. However, some varieties have low fruit setting rates, so artificial help is recommended. When blooming, carefully shake the male and female flower buds so that pollen will spread in the air. Or you can put on gloves and touch the male buds, so that the pollen will stick to the gloves, and then touch the female buds to achieve successful pollination. In addition, attention should also be paid to the management of the flowering period.

1. How to pollinate

There are many varieties of grapes, but most varieties are pollinated by wind or bees and do not require artificial help. However, some varieties do not help with pollination and have lower fruit setting rates. When it blooms, you can carefully shake the female and male flower buds so that the pollen will spread in the air and help pollination. Or put on gloves and touch the male buds. The pollen will stick to the gloves, and then touch the female buds. This may promote successful pollination and increase the fruit setting rate.

2. How to manage

1 Humidity: Stop watering after it blooms and maintain a good humidity environment. The optimum humidity is 50%. If you water again at this time, the soil temperature will drop, affecting absorption and thus fruit setting.

2. Temperature: It likes a warm environment. The most suitable temperature during the flowering period is between 25 and 28 degrees, and it should be controlled between 16 and 18 degrees at night. If it is grown in a greenhouse, you should pay attention to more ventilation during the day. Pay attention to temperature control at night in the open air. If it is below 15 degrees, it will affect flowering.

3. Nutrients: Fertilize appropriately before flowering, optional High phosphorus fertilizer and sufficient nutrients can promote flowering. Also spray boron fertilizer to facilitate fruit setting in the later stages. If there is a lack of nutrients, the flowering period will be shortened and the fruit setting rate will also decrease.

4. Lighting: During the flowering period, you should get more sun and put it in a place with good light every day, ensuring that the duration is between 7-9 hours. This can better produce photosynthesis and facilitate the differentiation of flower buds. .
