1、 Control temperature

Potted grapes should be moved indoors after cooling in winter, and pay attention to temperature control. The indoor temperature should not be too high. Just keep it between 0 ℃ and 5 ℃. Do not put it in the heating room. If the temperature is about 10 degrees, the budding eyes will germinate in advance, which is unfavorable to the later growth, flowering and results

2、 Timely watering

Although it will stop growing in winter, it needs to be watered regularly. Because if you do not water for a long time, the basin soil is dry, and the root system cannot absorb water, it is easy to be damaged, and the bud eye will dry up, which is unfavorable to the germination of next year. You don't need to water too often. Just water it once a week and let the soil slightly wet

3、 Increase the application of base fertilizer

After winter, the pot should be changed once. At this time, it should be combined with fertilization. The organic fertilizer after fermentation is OK, and the amount should not be too much. Pay attention not to put it directly near the root system, otherwise it will burn the root. After this treatment, the soil is loose and nutritious, and the plant can grow better next year

4、 Shaping and trimming

Prune in time after winter. Prune the thin and weak branches, pest branches, bare branches, through cuttings and branches after fruit bearing. The specific method should be determined according to the variety and growth trend of the grape tree. At this time, it should be re pruned to save nutrients as much as possible. After such treatment, it is beneficial to the winter and the growth of next year. If not pruned, a lot of nutrients will be consumed in the whole winter, which will affect the germination, flowering and fruit of the next year
