How to deal with potted grapes in winter and how to overwinter

1. Control the temperature

Potted grape vines should be moved indoors when the temperature drops in winter, and attention should be paid to temperature control. The indoor temperature should not be too high, just maintain it between 0 and 5 degrees. Do not place it in a heated room. If the temperature is around 10 degrees, the buds will germinate prematurely, which will be detrimental to later growth, flowering, and fruiting.

2. Water in time

Although it stops growing in the winter, it still needs regular watering. Because if you don't water it for a long time, the soil in the pot will dry out and the roots will not be able to absorb water, which will easily cause damage and the buds will dry up, which will be detrimental to germination next year. You don't need to water too often, just once a week to keep the soil slightly moist.

3. Increase the application of basal fertilizer

The pot should be changed once after winter, and fertilization should be applied at this time. Fertilizer can be fermented organic fertilizer, not too much. Be careful not to put it directly near the root system, otherwise it will burn the roots. After this treatment, the soil will be loose and nutritious, so the plants can grow better next year.

4. Plastic Sculpting

After winter, pruning should be done in time, and weak branches, diseased and insect-infested branches, overgrown branches, interlaced branches and branches after fruiting should all be pruned once. The specific method should be determined according to the variety and growth of the grape vine. At this time, heavy pruning is required to save nutrients as much as possible. This treatment will be beneficial for wintering and growth next year. If not pruned, a lot of nutrients will be consumed throughout the winter, which will affect germination, flowering and fruiting in the next year.
