Black-eyed Susan how to raise black-eyed Susan breeding methods and matters needing attention

Black-eyed Susan is a plant introduced and cultivated from abroad in China, which is mainly ornamental to flowers. Black-eyed Susan's flowers are similar to chrysanthemums. In other words, they are commonly found in orange, and the stamens in the middle of the flowers are black, so they are so named. There are a lot of people raising black-eyed Susan now, but before breeding, we still need to know its breeding technology in advance.

How does black-eyed Susan raise it?

1. Black-eyed Susan sowing is usually carried out in spring, and if possible, you can also advance some time, mainly to ensure that the temperature of germination is about 20 ℃, but autumn sowing is not recommended, because black-eyed Susan is not too cold-resistant, and there are no warm measures, sowing will only waste seeds.

2. Black-eyed Susan likes fertilizer. Once planted, she should often water and fertilize from spring to autumn in order to blossom continuously. The basin soil should use nutrient-rich culture soil, and nitrogen, phosphorus and potassium compound fertilizer can also be used as base fertilizer, and liquid fertilizer should be continuously replenished in the process of cultivation. It will be more suitable to irrigate pollution-free cultivation nutrient solution regularly. Plants are often sprayed with water at the height of summer to improve environmental humidity.

3. Black-eyed Susan needs all-day sunshine or slight shade, and likes to be warmer. The medium can be mixed with 2 parts of peat, 2 parts of rotten leaf soil and 1 part of perlite or river sand. It is less tolerant to drought, quantitative watering is beneficial to growth, and pruning from time to time can make the plant grow more luxuriantly and promote flowering.

Culture method of black-eyed Susan

1. Environment. Black-eyed Susan prefers warm and humid environment, and likes to grow in sunny environment. The best growth temperature of black-eyed Susan is between 20 degrees Celsius and 30 degrees Celsius. Black-eyed Susan is not resistant to cold. Once the temperature reaches below 7 degrees Celsius, it will be difficult to maintain normal growth.

2. Fertilizer. Black-eyed Susan is a kind of plant that likes fertilizer very much. once she begins to grow, she should strictly fertilize her, which is beneficial to his flowering.

3. Soil. Black-eyed Susan's growth soil should choose nutritious soil, can use suitable fertilizer as base fertilizer, and continue to supplement in the breeding process, if regular fertilization work will be more conducive to plant growth.

4. Moisture. Black-eyed Susan is not tolerant to drought, so she must be watered in time in the breeding process and sprayed with water as a spray in summer to maintain environmental humidity.

Notes for Black-eyed Susan

1. The most suitable sowing time for Black-eyed Susan should be in March every year, and the pot should be changed gradually according to its growth state. At the final shaping time, the flowerpot is about the most suitable for 20cm. Another propagation method for Black-eyed Susan is cutting propagation.

2. The coring work can be carried out at an appropriate time, which can lead to branching, and the flower stem can be trimmed in time after flowering.

Diseases and control methods of black-eyed Susan

1. Powdery mildew. Control method: control the amount of nitrogen fertilizer used. Before the onset of the disease, 60% Dysen zinc wettable powder was sprayed every two weeks or so. At the initial stage of the disease, 1000 times of methyl topiramate or 1000-2000 times of Fenxiu Ling could be sprayed to prevent and cure the disease.

2. Grey mold. Prevention and treatment: pay attention to ventilation and light transmission, control humidity. In the initial stage of the disease, spraying 1500 times of 70% methyl topiramate or 80-1000 times of Dysenamine every 10 days can effectively carry out prevention and treatment.

3. Stem rot. Prevention and treatment: in the early stage of the disease, carbendazim can be sprayed to kill or 65% dimethazone 600-800 times, and so on.

The breeding method of black-eyed Susan is relatively simple. First of all, it is necessary to have an understanding of its growth habits, shading in summer and temperature adjustment in low temperature in winter. Otherwise, it may cause plant death.
