When will Lu Binghua sow?

Lubinghua belongs to the legume family, and its stem grows upright. There are many small branches from the base, and the whole tree has brown bristles. So, when will Lu Binghua sow seeds?

When will Lu Binghua sow

The seeds of Lubinghua can be sowed in spring or autumn. The sowing time is from February to April in spring and from September to October in autumn. But it is most suitable to sow in autumn. After sowing in autumn, it will blossom in April-June of the following year. Most of the seeds were sown with a hole plate, one grain per plate, and the soil with loose and uniform, water-retaining and breathable soil was used for breeding.

II. Daily management of planting of Lubinghua

1. Temperature

Lu Binghua likes a cool climate and can't stand the heat. Winter can temporarily withstand a low temperature of about zero degrees, so it is recommended to plant it indoors when the temperature is below ten degrees. Lu Binghua also can not stand the high temperature, when the temperature is higher than 30 degrees, it will dormant. Many potted people choose to sow in autumn and watch the flowers bear fruit in early summer, so as to avoid the high temperature in summer. Spring sowing potted friends should pay attention to summer conservation, because Lu Bing flowers are extremely prone to diseases.

2. Lighting

Lu Binghua likes light, grows well in sufficient light, has strong branches, thick and long spikes, and many and bright flowers. Under the condition of slight tolerance to shade and lack of light, it is easy to grow, the branches are thin, the leaf color is dim, the spike is small and the seed setting rate is low, which greatly affects the ornamental value.

3. Soil

Lu Bing flowers have certain requirements on the soil, and they are suitable for growing in weakly acidic soil. When planting in the north, you should pay attention to avoid the long-term use of ferrous sulfate and aluminum sulfate to regulate the acidity and basicity of the soil, because the cations in these two types of regulators will accumulate in the soil and be toxic to flowers. It is suggested that we should use pond mud mixed humus soil as a pot soil for planting Lubing flowers.

4. Fertilization

Lu Binghua does not have high requirements for nitrogen fertilizer because the rhizobium parasitic on their roots can fix nitrogen and provide nitrogen fertilizer for plant growth. However, they have higher requirements for phosphorus and potassium fertilizer, sufficient phosphorus and potassium fertilizer can promote flower bud differentiation, increase the length of flower spike and make the flower color bright, and can improve the seed setting rate after flowering.

5. Reproduction

The reproduction of Lubinghua is mainly seed sowing, and most potted people choose to sow in autumn, watch the leaves in the process of maintenance in winter, enjoy the flowers in spring, and die after seeding in summer. this avoids the difficulty of nursing in the high temperature disease-prone period in summer. There are also some potted friends who cut the branches from the roots in spring and cut them into small segments of 10 centimeters, soak them in rooting powder and cut them in clean wet sand. Generally, a complete root system can be developed in about a month and a half. Transplant.

6. Diseases and insect pests

The common diseases of Lubing flower are root rot, rust and powdery mildew, which are all caused by fungi, which are related to high temperature, high humidity and poor permeability caused by excessive planting density. In order to avoid the disease, some flower beds will spray regularly to prevent the disease, so that the bacteria will develop drug resistance over a long period of time, and it will be more difficult for potted friends to deal with the disease when they buy back the flowers, so they should pay attention to observation when buying. Those leaves with white residue had better not be bought back.
