Grape seed germination usually takes 7- 10 days. Because of the different climatic conditions in different regions, grape germination is affected by ground temperature and air temperature. When the local temperature is above 12℃ and the average temperature is above 10℃, the grapes begin to sprout. This period is generally from April 1 day to mid-April. In the northern hemisphere, vines begin to sprout at the end of March and the beginning of April every year. With the increase of temperature, it will germinate and grow one after another, and then the leaves and branches of grapes will grow gradually. When the grapes germinate, they must be ploughed and weeded for the first time in order to ventilate and absorb rainwater. In addition, the work of eliminating pests and diseases should also start and continue until the end of July. Then the leaves and vines of the grapes also grow, and later they will grow tidbits on the vines.
