1、 Curing method

1. Temperature: it likes high temperature and is relatively heat-resistant. The suitable temperature for development is between 20 ℃ and 24 ℃

2. Watering: it likes humidity and needs to keep the soil from drying and hardening for a long time. In terms of water replenishment, it needs an appropriate amount, otherwise it will lead to ponding in the basin soil and root rot

3. Fertilization: it grows rapidly and needs a lot of nutrients. The nutrients in the soil are far from enough, so it needs to supplement nutrients during its growth period. There are two ways to supplement nutrients, one is to fertilize the soil and the other is to fertilize the branches and leaves. The former is used once every two weeks and the latter is once a month. The two can be used together. To fertilize the soil, try to use fertilizer with mild fertilizer effect, such as farmyard fertilizer; Liquid fertilizer should be used for foliar fertilizer

4. Light: it likes sunshine, but it is not resistant to strong light. It needs proper shade in the maintenance process. It is OK to ensure that there is six hours of astigmatism every day

2、 Breeding skills

1. Propagation: its propagation method generally adopts the sowing method. After the spring, sprinkle the seeds into the soil, then apply water once, and maintain them at a temperature of about 20 degrees. The seedlings can emerge in about three days. After emergence, do not transplant them first, and they can be transplanted when three leaves grow

2. Weeding: if it is a large area of maintenance plants, weeds are easy to grow in the land, so it needs to be weeded in time. Herbicides can be used for weeding for two times, one when the weeds are just beginning to grow, and the other when the weeds are about to bear seeds. When weeding, it should be noted that the herbicide must be diluted according to the instructions to avoid damage to the plant due to excessive concentration

3、 Problem diagnosis

1. Insect pests: generally, it will not be infected with insects. If insects are found, it can be sprayed with carbendazim. The agent needs to be diluted before spraying

2. Pathological changes: if it is found that the branches and leaves are drooping and the flower color becomes lighter, it may be due to excessive light. At this time, it is necessary to shade the plant properly to solve this problem

4、 Other issues

1. Toxicity: it is non-toxic and can be safely raised at home without any impact

2. Whether it can be cultured indoors: it can be cultured indoors. It has little demand for light. It can meet its light demand by placing it in bright places such as the balcony at home. In addition, it also has a good absorption capacity for harmful gases. If there is a newly decorated house, you can choose to cultivate several pots of purple flowers, which can not only absorb harmful gases such as formaldehyde, but also have good ornamental value
