When does the herb Yu Mei usually sow and blossom? How long is the growth cycle? How do you plant it?

Yu Mei, also known as Lichun, Sai Peony, Manyuan Spring, Artemisia annua, Yumei Grass, Dance Grass, is commonly cultivated in various parts of China. So when does it usually sow and blossom? How long is the growth cycle? How do you plant it? According to the data of Papaveraceae, Yumei is a biennial herb. Big purple, white, pink or red flowers bloom in April and May, which are very beautiful. Native to Europe and northern Asia, it is especially loved by Belgians and is designated as the national flower.

When does the herb Yu Mei usually sow and blossom?

1. Sowing time of Beauty Yu

The sowing time of Yu beauty is from March to April in spring or from September to October in autumn. The temperature at which Yu Mei sprouts is about 20 degrees, so the specific situation can be determined according to the local temperature.

2. Yu Mei needs to sow seeds in the autumn of that year, then survive the winter safely, and will not blossom until April and May of the following year. However, this kind of farming needs to go through a winter, so it needs to go through a long cycle.

3. The suitable temperature for the growth and development of Yumei is 5 ~ 25 °C. the flowering period is shortened and the temperature difference between day and night is large in the area with high temperature in spring and summer. The low temperature at night is beneficial to the growth and flowering, and grows well in the high altitude mountain area, and the flower color is more colorful. The life span is 3 to 5 years. Cold-resistant, afraid of summer heat, like sunny environment, like good drainage, fertile sandy loam. Do not tolerate transplanting, avoid continuous cropping and stagnant water. It can broadcast itself. The florescence is from May to August.

How do you grow beauty Yu?

1. Yumei is mainly propagated by sowing and is usually cultivated for 2 years. Yumei flowers and plants of the same genus are taproot, few fibrous roots, and are not resistant to transplant, so direct seeding is applied. If it is needed for garden layout, it is best to use a nutrition bowl or small paper basin to raise seedlings, even a bowl or pot transplant, otherwise it is difficult to survive or grow poorly. The sowing date is determined according to the climatic characteristics, and the northeast region is relatively cold, which can sprout as early as possible in spring. Small seeds, fine sowing, using strip sowing, row spacing of 25-30 cm, cover the surface with hay to protect against cold in severe winter. The suitable temperature for seed germination is 20 ℃. Families can broadcast live in flowerpots.

2. Sowing and reproduction. It can be sown in spring and autumn, generally speaking, spring sowing is from March to April, florescence is from June to July, autumn sowing is from September to November, and florescence is from May to June of the following year. In order to collect seeds, it is best to sow in autumn. The soil should be cleaned up fine, make the bed watered, and then sow or strip sow. Because the seeds of Yu Mei are small, when sowing, the soil should be leveled and beaten finely. After sowing, there is no need to cover the soil, but it can also be covered with a thin layer of fine sand. The thickness of the covered soil should not be seen (0.2-0.3 cm). In North China, because of the severe cold in winter, it is difficult for seedlings to survive the winter, so the direct seeding of "Lesser Snow" in early winter is often used, so that it can germinate and grow as soon as possible in spring.

3. It is also possible to make Yu Mei blossom when she is planting that year, but you need to master certain skills.

First of all, it is necessary to sow Yu beauty in spring. The sowing time is in the early March, and after the soil begins to thaw, you can choose to sow seeds in the open field or in pots. The method of sowing is not difficult. If sowing in a pot, the soil needs to be sorted out, put into a basin, and then watered thoroughly. After the water is completely permeated, the local seeds of Yumei are mixed with fine sand, and then sprinkled evenly in the flowerpot without covering the soil when sowing.

The second is the maintenance of Yu Mei. After sowing, Yu beauty needs the best work such as moisturizing and shading, which can be covered with plastic film. After the seedlings grow out, you can take off the plastic film. With the growth of seedlings, seedlings can be properly intersprouted.

There is also a very important point is water management. During the period from April to May, the growth of Yu Meimei will gradually accelerate. At this time, it is necessary to ensure adequate water and fertilizer and apply thin fertilizer once a week. In this way, the beauty of Yu will blossom around the middle of May.
