How do you protect grapevines from the cold in winter so they survive the winter safely?

There are many grape varieties, and they are planted in every region of our country; the grape is a nutritious and delicious fruit. But how do planted grapevines overwinter? What are the common varieties?

1. How do grapevines overwinter?

In regions that are warm all year round, grapevines can basically overwinter naturally. But in regions with severe winter cold, you need to irrigate with freezing water at the right time before winter sets in, and once the water has dried a little, earth up around the vines for cold protection. Before that, you need to do a good job of winter pruning and clearing the orchard, and then the grapevines will generally be able to overwinter safely.

2. What varieties of grapevines are there?

1. Jingxiu

Jingxiu is a new variety bred by hybridizing Muscat Hamburg, Red Seedless and Pannonia varieties as parent stock; it belongs to the Eurasian species. Its berries are large, with a maximum berry weight of 11 grams and an average berry weight of 6.3 grams. The clusters are fairly large, with a maximum cluster weight of 1100 grams and an average cluster weight of 500 grams. The berries are set densely. The skin is moderately thick, the flesh is thick and especially crisp, sweet and juicy.

2. Lady's Finger

Lady's Finger is a diploid Eurasian variety bred in 1984 by the Japan Uehara Grape Research Institute from a cross of Unicorn and Baladi No. 2. Cultivated in the Jiangnan region of China, it can pass through normal dormancy; it has strong bud-break ability and vigorous growth, very large clusters, a high fruit-setting rate and good coloring, but the shoots are markedly late-maturing, and it is susceptible to white rot and severe sunburn. When cultivation and management are not done properly, this variety is indeed difficult to fruit, and its yield is extremely unstable.

3. Hutai No. 8

Hutai No. 8 grapevines grow vigorously, tolerate low temperatures, do not split, store well and have excellent quality; they have a strong ability to fruit repeatedly, and once ripe they have a distinctive aroma. In appearance, the clusters are neat, the berries are large, the bloom is thick, and they are sweet and tasty. The ripe berries contain 15-25% glucose as well as various minerals and vitamins beneficial to the human body, and are rich in the anti-cancer trace element resveratrol, making them a true treasure among fruits.

4. Kyoho

Kyoho is a European-American hybrid. When the fruit of this variety ripens, the berries on the cluster should be evenly set; the berries weigh 10-14 grams, are purple-black, have plenty of bloom, are juicy with a fleshy sac, taste sweet and sour, and have a strawberry aroma.

To let grapevines overwinter smoothly, timely and thorough management work is indispensable.
