1、 Before germination

Before the germination and growth in spring, it is a critical period for watering. At this time, if sufficient water supply is provided, it can play a role in promoting new buds. At this time, watering can be sufficient. It is just in the period of water demand. The roots can absorb it and meet the needs of germination and branching. At this time, if you do not pay attention to water application, the effect of germination will be greatly reduced

2、 Before flowering

About 10 days before flowering, it is also a stage that needs water. Before flowering, the grapes in the pot will grow rapidly, the new shoots and inflorescences will grow faster, and the effect of transpiration and evaporation is also strong. Therefore, there is a lot of water demand, and timely water replenishment is needed. However, it should be noted that water should not be applied during the flowering period to prevent flower buds from falling

3、 Flower lag

Within 10 days after the flower falls, the new shoots begin to thicken rapidly and have strong growth capacity. At this time, the leaves also increase rapidly and the root absorption capacity becomes stronger. At this time, it is very necessary to apply water

4、 When coloring

Although the number of berries grown in potted plants is limited, the coloring period is also the peak of growth. At this time, the growth rate is also very rapid. If there is no sufficient water and nutrient support, the quality of grapes is not good
