Extended data
Although the day lily originated in the warm zone, it is cold-resistant. After autumn, although the stems and leaves are dead, the roots can still survive the winter in the soil. It is also very adaptable to soil and grows best in semi-cool and humid places. According to the climate and soil conditions in our province, it can be cultivated all over the country.
After several years of growth, underground rhizomes are easy to spread and stagger, which leads to poor plant growth and directly affects yield and quality. Therefore, it needs to be dug again every 4 ~ 5 years and propagated by ramets.
If the day lily develops well in the planting year, it can blossom. Flowers are usually picked in the second year. Flowers should be picked every morning, and it is best when the flowers are not fully open. Generally, each plant can take 2 ~ 3 kilograms of flowers every year, and the yield per mu is about 2000 ~ 3000 kilograms. 10 kg of flowers can make one kg of dried daylily, and 200-300 kg of dried daylily can be obtained per mu.
