1、 How to spend the winter

1. Changing pots: after falling leaves in winter, replace the pots, dispose of the old pot soil, trim the old roots, dry roots, fine and weak roots, and then plant in the pots. In addition, the base fertilizer should be applied once. The amount of organic fertilizer in the fertilizer should not be too much, nor should it be applied near the root system to avoid burning the root

2. Pruning: after falling leaves, prune the thin and weak branches, bare branches and Cross branches, and prune the branches after results. The specific method depends on the growth and variety. Pruning can save a lot of nutrients, which is more conducive to winter

3. Thermal insulation: potted plants can be moved indoors in winter, but can not be placed in a heated room. The temperature is between 0-5 degrees. If it is at about 10 degrees for a long time, the bud eye will germinate as soon as possible, which is not conducive to late flowering. It can also be buried in the soil. After pruning and watering, take it out of the flower pot, and then dig a pit and bury it. The depth of the pit is between 30-50cm. There is no need to water during this period, so it can survive the winter safely

2、 Do you need to hibernate

Potted grapes need hibernation. Only by hibernating can they accumulate enough nutrients, so that they can better germinate, blossom and bear fruit at the beginning of next spring. If it is not dormant and consumes too much nutrients in winter, it will affect the flowering of the next year and be unfavorable to the fruit
