How do potted grape trees survive the winter? Do they need to hibernate?

1. How to spend the winter

1. Repotting: After the leaves fall in winter, you need to repot, remove the old soil, trim old roots, dead roots, weak roots, etc., and then plant in the pot after everything is done. In addition, it is necessary to apply base fertilizer once. Organic fertilizer can be used. The amount should not be too much, and it should not be applied near the root system to avoid root burn.

2. Pruning: Pruning is still required after the leaves fall. Thin branches, overgrown branches and crossed branches should be cut off, and branches after fruiting should also be pruned. The specific method depends on the growth and variety. Pruning can save a lot of nutrients, which is more conducive to wintering.

3. Insulation: Potted plants can be moved indoors in winter, but they should not 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 buds will sprout too early, which is not conducive to later flowering. You can also bury it in the soil, take it out of the pot after pruning and watering, then dig a hole and bury it. The depth of the hole should be between 30-50 cm. No watering is required during the winter, so it can safely survive the winter.

2. Do you need to hibernate?

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 early spring of next year. If it does not hibernate, it will consume too many nutrients in winter, which will affect its flowering next year and will also be detrimental to fruiting.
