Temperature: it is most appropriate to keep it between 20-33 degrees, and it cannot be lower than 10 degrees in winter. Light: avoid strong direct light at noon in summer, and give direct light all day in winter. Watering: once every 2-3 days in summer and once every 5-7 days in winter. Soil: soil that uses air to retain water and fertilizer. Fertilization: once every 15-20 days, apply thin fertilizer frequently. In addition, pay attention to the prevention and control of diseases and pests.

1、 Temperature

It likes a warm environment. It is most suitable to keep the temperature at 20 to 33 degrees. In summer, it should not be too high, and in winter, it should not be too low, not less than 10 degrees. It may not grow or enter a dormant state below 10 degrees

2、 Illumination

It likes light and is resistant to half shade. During breeding, pay attention not to be exposed to direct light at noon in summer. It can be in the morning and evening. Direct light should be given throughout the day in winter

3、 Watering

Catharanthus roseus likes high air humidity, but avoid soil ponding. Spray more water during breeding to keep the basin soil dry and wet. Water once every 2-3 days in summer and once every 5-7 days in winter. Spray water 1-2 times a day

4、 Soil

The general soil can be cultivated, preferably the soil with air permeability, water conservation and fertilizer conservation. Rotten leaf soil, garden soil, river sand and perlite are configured in the proportion of 5:1:1:1

5、 Fertilization

It blooms and flourishes. It has more demand for scale potassium fertilizer and general demand for nitrogen fertilizer. When applying fertilizer, you can use self-made organic fertilizer or buy common fertilizer for raising flowers. The time is once every 15-20 days, and the principle is thin fertilizer and frequent application

6、 Precautions

It is relatively easy to cultivate flowers. It should be noted that the temperature should not be lower than 10 degrees. If it is lower than 5 degrees, it will be frozen. It is mainly light and moisture. It likes high humidity and needs to spray more water, but the soil should not be wet and should be watered less. Especially in summer and winter, it should be kept dry and wet. When pouring, it should be watered thoroughly. Dry refers to the dry soil of 2-3cm on the soil surface. Also note that direct light at noon must not be accepted in summer

If the humidity is too high, it will cause leaf diseases and insect pests, such as black spots and neck diseases and insect pests. So keep the water spray and the soil surface dry and wet, and don't be too violent. In case of diseases and insect pests, carbendazim or chlorothalonil can be sprayed
