When will the May 18th tobacco leaves be harvested?

Wuyi eight-leaf tobacco is usually harvested from late autumn to early winter, and the specific time varies according to weather, region, planting methods and other factors. Generally speaking, if the open-air cultivation method is adopted, the leaves will turn yellow and fall off in late autumn, which is a signal of bumper harvest. If greenhouse cultivation is adopted, the best harvesting time can be judged according to the planting time and tobacco growth. In a word, it is best to determine the harvest according to the local climatic conditions and tobacco growth.
