1. When should you not cut?

Generally, leeks are no longer harvested in late autumn and early winter. The main purpose is to nourish the roots, transfer nutrients to the stems and store them, and increase the yield and variety of leeks in the next year. Although leeks are perennial vegetables, they can be harvested many times a year. However, the time to cut leeks needs to be determined according to the growth of the plants, soil fertility and other conditions, so that the leeks can live longer, have a higher yield and better quality. It should be noted that the leeks planted in the same year should not be harvested, and the focus should be on root care. In addition, when cutting leeks, the standard is 7 leaves and 1 heart, and it is better to harvest them in the early morning.
