How to grow Catharanthus roseus

1. Temperature

Catharanthus roseus likes a warm environment, and the temperature generally needs to be kept around 20 to 33 degrees Celsius. It can grow well above 10 degrees or below 33 degrees.

2. Soil

Catharanthus roseus is not very demanding on soil texture, but cannot be cultivated in saline-alkali land. Also, avoid moisture and waterlogging, and provide breathable, drainable and nutrient-rich soil.

3. Lighting

Because the light intensity is different in spring, summer, autumn and winter, you should avoid sun exposure at noon in summer but it is okay in the morning and evening. It can be placed in the sun all day in winter.

4. Water

Catharanthus roseus likes high air humidity, so you can spray water on the plant frequently to keep the air dry and wet. Water once every 2-3 days in summer and once every 5-7 days in winter.
