How many times can I harvest leeks a year, and how long is the best interval?

Leek can be harvested all year round, with strong regeneration ability and continuous harvesting. There are many harvests in a year. Although the yield was high in that year, due to the lack of nutrients accumulated by plants, it will not only fail to maintain vigorous growth in the future, but also lead to premature aging. So it is not advisable to harvest too many times. So how many times a year is the most suitable harvest for leeks? It depends on the growth potential and the amount of fertilizer applied. Cut less if the growth is weak or the amount of fertilizer is small; On the contrary, those with strong growth or high fertilization can be cut more. Under normal circumstances, green leeks are harvested 2-3 times from the vernal equinox in spring. Under high temperature, leek grows slowly, and generally only leek flowers (flowers) are harvested. Autumn is the season for plants to accumulate nutrients, which is generally not suitable for harvesting. In winter, the softened leeks can be harvested. If harvested in this way, it can be updated every 5-6 years (even 7-8 years). For example, if you harvest 6-7 times a year, you should update it every 2-3 years. If you want to update its annual supply next year or the non-food is getting old, you can increase the number of harvests.
