1、 Curing method

1. Temperature: it has low requirements for temperature. Because of its cold resistance, it can also be planted in the north. As long as the temperature is not less than minus 10 degrees, it will not be frostbitten. The curing temperature should be controlled between 18 ℃ and 28 ℃, which is the best temperature range for plant growth

2. Watering: its growth consumes little water, and because it is relatively drought resistant, it needs to control the water slightly in the maintenance process. It needs to be watered every time when the soil is completely dry. The amount of watering is appropriate to wet the soil surface. Generally, watering once a week is enough

3. Fertilization: its growth consumes a lot of nutrients, especially during the growth period. According to its growth state, it needs topdressing once or twice a month. Each fertilization needs to dilute the fertilizer, otherwise it is easy to burn roots. Compound fertilizer can be used for fertilizer seeds, and farmyard fertilizer can also be used

4. Light: it has little demand for light. Generally, two to five hours of light a day can meet its demand. Avoid strong light every time. If the light is too strong, it is easy to burn branches and leaves

2、 Breeding skills

1. Reproduction: it can reproduce by sowing. Breeding seeds should be those of the current year, because the seeds are short-lived seeds and are not suitable for use every other year. When sowing, after selecting the seeds, soak them in warm water for four hours, and then plant them into the cultivation base and water them once. Generally, seedlings can develop in a week or two

2. Colonization: colonization shall be carried out as soon as possible after plant division. The soil with flat terrain and good drainage shall be selected for colonization. Open the hole at a distance of 50 cm from the row. When opening the hole, use pig manure as the base fertilizer, then put it into the plant, spread the roots of the plant, press the soil, and finally pour a fixed root water

3、 Problem diagnosis

1. Yellowing of leaves: the yellowing of leaves of plants may be caused by too strong light. It is necessary to transplant the plants to a cool place for a period of time. After it slows down, they can be cultured normally

2. Rotten roots: the rotten root strips may be caused by excessive watering. It needs to be dug out, the rotten root strips shall be removed, and the cuts shall be disinfected before replanting

4、 Other issues

1. Edible: it is edible. Starch can be extracted from the root and wine can also be made

2. Other functions: it can be used as medicine to treat joint pain
