1、 Curing method

1. Temperature: it can withstand low temperature and high temperature. There is basically no requirement for maintenance temperature. It can be planted in both the South and north of China

2. Watering: you don't need watering unless you encounter dry weather, because it can withstand drought. If the drought lasts for more than a month, it needs to be watered manually, usually once a week, until the soil is completely wet

3. Fertilization: it is resistant to barrenness and has low demand for nutrients, but this does not mean that it does not need topdressing. In order to promote growth, it is best to fertilize it once a month. Farmyard fertilizer or compound fertilizer with sufficient nutrients can be used. It should be noted that thin fertilizer should be used for fertilization, otherwise it is easy to cause fertilizer damage

4. Light: it can accept strong light environment and semi shade environment. Therefore, there is no need to tangle with the problem of light in the maintenance process. It is OK to breed normally

2、 Breeding skills

1. Propagation: it can be propagated by root splitting method. First, take out the underground rhizome, and then cut it into 10 cm segments for propagation. What should be paid attention to is that the incision needs to be disinfected before planting to avoid diseases and pests

2. Pruning: generally, it doesn't need pruning, just prune the dry and rotten branches

3、 Problem diagnosis

1. Pests: it has strong toxicity and is basically free of pests

2. Pathological changes: if its branches and leaves turn yellow, it is mostly caused by improper watering. If there is water in the soil, you need to control the water temporarily. When the water in the soil is completely dry, you can water it. If it is caused by too little water, you need to water it, but don't pour too much at one time. Just pour it until the soil is completely wet

4、 Other issues

1. Edible: it is inedible

2. Toxicity: its rhizome contains a lot of toxins and must not be eaten. The more developed its root system grows, the stronger its toxicity. For example, if the roots of other plants grow with their roots, it is difficult for other plants to survive. If you eat it carelessly, drink plenty of water and dilute the venom, otherwise it will make people have diarrhea
