1. Soil: this kind of plant can be cultivated in the soil with abundant and slightly alkaline nutrients, which is composed of garden soil, river sand and bone meal.
2. Watering: every time you want to water the plant, press the place where the stem of the plant has few thorns with your hand. If the ball of the plant sinks in and feels soft, the potting soil of the plant becomes dry. At this time, you can water the plant and thoroughly water the potting soil. In winter, less water should be given to the plants. At this time, the time when the plants become soft will be shorter, so there is no great demand for water
3. Light: this kind of plants like the place with bright light, so they should be placed on the balcony with good sun light. But in summer, too strong sunlight will hurt the leaves of the plant, so after entering summer, you should put it in the place with weak light or cover the sun a little.
4. Fertilizer: add fertilizer to the plant once a month in spring and autumn, and supplement some consumed fertilizer to the plant after the flower withers. In winter, we don't need to add fertilizer to it. At this time, the plant grows slowly.
Usually put the plant in a good position of air circulation, so that the plant will not easily infect diseases and insect pests.
