1、 Do you use water in winter

Whether potted grapes need watering in winter depends on the specific winter methods. If it is placed indoors for the winter, it should be watered. Water it about once a week. Don't let it lose water, otherwise the root system will be damaged and it won't be able to survive the winter safely. If it is taken out of the flower pot and buried in the soil for winter, it needs to be watered enough before it is buried in the soil, and there is no need to water in the later stage. The humidity of the soil can ensure its safe winter

2、 How to maintain it in winter

1. Timely basin change: it needs to change the basin after winter, replace all the original soil, and trim the root system. Cut off its old roots, withered roots and weak roots, so that it can better absorb nutrients in the later stage. At this time, it should be carried out together with the application of base fertilizer. The fertilizer should be organic fertilizer after decomposition

2. Reasonable pruning: after winter, it is necessary to prune its sick and weak branches, bare long branches and Cross branches, and the branches that have borne fruit should also be pruned. The specific pruning method depends on the tree potential and variety. Generally, 1-2 bud holes are reserved for the short shoots, 4-6 bud holes are reserved for the middle shoots, and 8-10 bud holes are reserved for the long shoots. Carry out reasonable pruning, so that not only the plant shape is more beautiful, but also the growth will be more vigorous in the later stage, which is also beneficial to the winter
