It cannot be watered when it is blooming. The humidity needs to be reduced, and the humidity should be around 50%. If you water at this time, the soil temperature will decrease, and its absorptive capacity will also decrease. As a result, the fruit setting rate of flowers that bloom within three days will decrease. Therefore, do not water randomly and grasp the time well. Also, fertilize. At this time, high phosphorus fertilizer should be applied, and boron fertilizer should be sprayed before flowering to promote flowering and increase fruit setting rate.

1. Why not water during the flowering period

The management of grapes during the flowering period is very important and determines the fruit setting rate. Generally, a large amount of water should be poured before flowering to ensure soil moisture. It is not recommended to water when blooming, as long as the soil humidity is maintained at 50%. Because the temperature of the soil will decrease after watering, the absorption capacity of the plant will also decrease, and the fruit setting rate of flowering within three days will decrease. Therefore, you must grasp the watering time and do not water randomly.

However, if the soil moisture is low, less than 50%, water must be replenished. At this time, small amounts of water should be irrigated. You can use drip irrigation to allow the water to slowly penetrate inside. As long as the roots are slightly moist, do not irrigate with large amounts of water.

2. What fertilizer to apply when blooming

It consumes a lot of nutrients during the flowering period and needs to be replenished with fertilizers in time. About a week before flowering, boron fertilizer should be sprayed on the leaves, and high-phosphorus fertilizer should also be applied to promote flowering. In this way, the flowers will be healthier, the flower organs will develop better, and the fruit setting rate will be increased. In addition, fertilization should be applied after the flowers have died to supplement nutrients to facilitate the growth of the fruit in the later period.

3. Other management during the flowering period

In addition to watering and fertilizing, you should also pay attention to temperature during flowering. It likes warmth, and the warmth should not be too low or too high. The temperature during the day is 28 degrees, and the best temperature at night is between 16-18 degrees. Greenhouse cultivation should be ventilated frequently to allow better air circulation.
