When to bury northern grapevines and how to survive the winter

1. When to bury the soil

The temperature in northern regions is too low in winter, usually below minus 6 degrees Celsius. In such an environment, if the grape branches are not buried in the soil, they will be frozen, affecting germination and flowering in the second year, and may even cause the death of the plants. The time of burying the soil must be strictly controlled. It is usually carried out half a month before freezing, which is probably mid-November. If the branches are buried too early, they will sprout in a warm environment. If they are buried too late, they will be frozen.

2. How to spend the winter

1. If you want it to survive the winter safely, you must pay attention to the method. Before burying the soil, water the plants once to prevent frost damage to the roots and avoid early spring drought. When watering, make sure to water enough to saturate the soil, and then cover the soil when the ground is slightly dry.

2. In addition to watering, pruning is also necessary. Autumn pruning usually starts in mid-October every year after the leaves fall. The orchard is completely cleared of dead branches and rotten leaves, the grapes on the racks are taken down, the branches and vines are laid flat on the ground and tied with straw ropes. Be careful not to bury too much soil the first time, just make sure the branches and vines are not exposed.

3. The soil should be buried twice, and the second time should be done before the ground freezes. If young trees need to be buried early, large trees can be buried later. When burying the soil for the second time, you should also cover it with an appropriate amount of hay or corn stalks. This can increase the temperature of the roots and help prevent cold. At this time, the thickness of the soil buried on the branches and vines should not be less than 60 centimeters, and the width should be between 1.8 and 2 meters.
