After that, pruning is required to cut off thin branches, leggy branches and cross branches, which can save a lot of nutrients and help survive the winter. After cooling down, move it indoors and control the temperature between 0-5 degrees.

1. How to survive the winter

1. Repot: After the leaves fall in winter, you need to repot, dispose of the old pot soil, prune old roots, dead roots, thin roots, etc., and then repot Plant in pots. In addition, base fertilizer must be applied once. Organic fertilizer is sufficient. The amount should not be too much, and it should not be applied near the root system to avoid root burning.

2. Pruning: Pruning should be done after the leaves fall. Cut off thin branches, leggy branches and crossing branches, as well as branches after they bear fruit. The specific method depends on the growth and variety. Pruning can save a lot of nutrients, which is more conducive to winter.

3. Insulation: Potted plants can be moved indoors in winter. , but it cannot be placed in a heated room. The temperature should be between 0-5 degrees. If the temperature is around 10 degrees for a long time, the bud eyes will germinate as early as possible, which is not conducive to later flowering.

You don't need to water it during the period, so you can survive the winter safely.

Potted grapes need to hibernate. Only by hibernating can they accumulate enough nutrients so that they can germinate, bloom, and bear fruit better in the spring next year. If they are not dormant and consume too much nutrients in winter, it will affect the flowering of the next year and be detrimental to the results.
