How to cut Tongren grape seedlings and when is the easiest time to cut them?

Cutting shall be started when the local soil temperature is stable above 10℃. In North China, it is usually from late March to early April, but in North China, cutting can be carried out in mid-April, and in Central China and East China, it can be carried out in the middle and late February.

Full-light spraying green branch cutting in hot days can carry out rapid propagation of a batch of grape seedlings, and the time is about May to June (July) in summer. After more than 20 days, select semi-lignified branches with well-developed winter teeth to take root. After several months of hardening, vine species with mature branches can be obtained. Now the weather is getting colder and colder, and the post-growth period of grapes is a little shorter, so it is not easy to get high-quality seedlings. However, lignified branches can be selected for high pressure and then cuttage transplantation in winter, but the number of seedlings will be less. Why do you use branches cut in winter and stored for one winter for cutting? This is to protect the fruiting mother tree, so as to facilitate the next year's harvest and avoid the influence of pruning and bleeding in spring on the tree potential, thus affecting the grape yield.
