1、 When can't you cut it

Generally, leeks are no longer cut in late autumn and early winter. The main purpose is to raise roots, transfer nutrients to stems for storage, and improve the yield and variety of leeks in the coming year. Although leeks are perennial vegetables, they can be harvested many times a year. However, cutting leeks needs to be determined according to plant growth and soil fertility, so as to make leeks live longer, have high yield and good quality. It should be noted that the leeks planted in that year should not be harvested and should be mainly rooted. In addition, according to the standard of 7 leaves and 1 heart, the leek is harvested in the morning, and the variety is better

2、 What month does the North cut

Northern leeks can generally be cut until November, and then start harvesting leeks in spring. If it is cultured in a greenhouse, it is possible all year round. Generally, harvest every 30 days or so, and harvest 3-4 times in spring; The growth rate is slow in summer, and the harvest times will be less, mainly harvesting bolt leek or leek flower; In autumn, it can be harvested 1-2 times in order to raise roots for overwintering

3、 Growth habit

Leek is a perennial vegetable of Liliaceae, which has strong adaptability, cold resistance and heat resistance. The suitable growth temperature is between 15 ℃ and 25 ℃, and the underground part can withstand lower temperature. It can accept medium light intensity and strong negative resistance. If the light is too weak, the yield will be low, which is easy to lead to premature aging. It has strong adaptability to soil texture, and the suitable pH is between 5.5-6.5. Leek has great demand for fertilizer and strong fertilizer tolerance
