1、 Curing method

1. Temperature: wuyuyu prefers warmth to cold. The maintenance temperature should be controlled at about 25 degrees. If the temperature is too high, it can be cooled by spraying water mist. If the temperature is lower than 15 degrees, the growth of the plant will be affected. If it is lower than 10 degrees, the plant will be frostbitten. Therefore, during the maintenance process, the maintenance temperature must be controlled to avoid damage to the plant

2. Watering: summer and autumn are its growth period, so it should be watered frequently. It needs to be watered two to three times a week. Early winter and early spring are not its growth period, so it needs to control the water content. Watering once a week and ten days is enough. In winter, its ball will shrink slowly. It is necessary to keep the soil dry. Generally, it does not need watering at this time

3. Fertilization: during the growth period, it consumes nutrients quickly, and the nutrients in the soil can not meet its needs. It needs to be fertilized once a month. Compound fertilizers with low nitrogen, high potassium and phosphorus should be used. It should be noted that when fertilizing, the fertilizer should not be in direct contact with the plant

4. Light: it likes to grow in an environment with good ventilation and sufficient light. It is not resistant to strong light. Therefore, astigmatism should be the main type of light. Especially in summer, it is best to move to an indoor semi shady place for maintenance. The daily light time should be more than five hours. Except in summer, it can be under normal light in other seasons without shade

2、 Breeding skills

1. Propagation: it can be propagated by sowing method. The sowing time is in April and may every year. First, disinfect the basin soil, and use the plain sand soil disinfected by steam. Then wet the soil with basin immersion method and sprinkle the seeds on the soil surface. Because its seeds are relatively small, it is not necessary to cover the soil, and cover the soil surface with glass sheets to moisturize it. After the above steps are completed, put it in a cool place for maintenance, Control the temperature between 15 and 25 degrees, and you can sprout in about ten days

2. Pruning: generally, it does not need pruning. It will only be pruned when beheading and breeding

3、 Problem diagnosis

1. Insect pests: Black Feather jade is more likely to be infected with the invasion of pests such as red spider, and may also be infected with rust or stem rot. it can be regularly treated with pansadomycin and Triadimefon. It should be noted that in order to avoid its resistance, the control agents should be changed frequently and can not be used for a long time

2. Disease: if the plant has soft collapse of the sphere, it may be the root rot. the most direct cause of root rot is excessive watering and poor drainage of the basin soil. It is necessary to change the basin and soil

4、 Other issues

1. Toxicity: non toxic

2. Edible: not edible
