1. Plastic trimming

2. Control the temperature

3. Apply more base fertilizer

4. Water in time

Grapes maintained in pots should also be pruned in winter. Weak branches, interspersed branches, leggy branches and diseased branches should be cut off. The branches after fruiting should also be treated. The specific method will be determined according to the variety and growth condition. At this time, the temperature is low. To control the temperature, it can be placed indoors and the temperature should be controlled at 0-5 degrees. After winter, it should be combined with changing the pot and applying base fertilizer once. In addition, although it has gone dormant, it cannot lose water and needs to be watered once a week.

1. Plastic pruning

When the temperature is low in winter, it will stop growing and begin to go dormant. During this period, they need to be pruned. Weak branches, interspersed branches, leggy branches, and diseased branches should be cut off. The branches after fruiting should also be pruned. The details will be determined according to the variety and growth condition. Generally, 1-2 buds are left on the short tips, 4-6 buds are left on the middle tips, and 8-10 buds are left on the third tips. Reasonable pruning can save a lot of nutrients, which is beneficial to winter and next year's growth.

2. Control the temperature

Potted plants If the temperature under management is relatively low, you can move it indoors, but pay attention to the indoor temperature to be well controlled and maintained between 0 degrees and 5 degrees. It should not be too high. If the temperature exceeds 10 degrees, the buds will germinate early and consume nutrients, which is detrimental to the growth of the next year.

3. Apply additional base fertilizer

After winter, base fertilizer should be applied once in conjunction with repotting. Fermented organic fertilizers are sufficient, such as sesame paste residue, chicken manure or bean cake fertilizer. Be careful not to apply too much fertilizer, nor to apply it directly near the roots to avoid burning the roots.

4. Water in time

Although it will go dormant in winter, the watering of potted plants cannot be relaxed. If water loss occurs, the root system will be easily damaged and the bud eyes will dry up, which will affect next year's germination. Therefore, it is necessary to water in time, usually every week, so that the soil is slightly moist.
