1、 Breeding method

1. Soil: the nutrient rich and slightly alkaline soil mixed with garden soil, river sand and bone meal can be used to cultivate such plants

2. Watering: every time you want to water the plant, use your hand to press the place where there are few thorns on the stem of the plant. If its ball is sunken and feels soft, the pot soil of the plant will also become dry. At this time, you can water the plant and pour the pot soil thoroughly. In winter, less water should be given to the plant. At this time, the time for the plant to soften will be shorter, so there is no great demand for water

3. Light: this kind of plants like bright places, so they should be placed on the balcony with good sun light. However, in summer, too strong sunlight will damage the leaves of the plant, so after entering summer, it should be placed in a weak place or slightly shielded from the sun

4. Fertilizer: add fertilizer to the plant once a month in spring and autumn, and supplement the plant with some consumed fertilizer after the flowers wither. In winter, it doesn't need to be fertilized. At this time, the plant grows slowly

2、 Precautions

Usually put the plant in a well ventilated place, so that the plant will not be easily infected with diseases and pests
