It is a light loving plant, which likes to grow in the sun very much. During the growing period, sufficient light should be ensured so as to make the leaves shiny and the flowers bright. Therefore, it can be placed in a place with good light. You can't stay in a dark place for a long time. If you stay in shade, your growth will be affected, causing the leaves to turn yellow and fall.
Catharanthus roseus has strong adaptability and can stand barren soil, but it can't grow in alkaline soil, and it can't grow in hard and airtight soil, which is easy to cause yellow leaves and difficult to bloom normally. The sapropel can be mixed with coarse sand, which can meet the two requirements of the soil.
The suitable temperature for different growth periods is different. It can be kept at 18-24 ℃ from March to July. From September to march of the next year, the temperature can be kept at 13-18 ℃. In winter, it can not be lower than 10 ℃.
Water supplement does not need too much. If it is too wet, it will lead to water accumulation in the basin, which will rot the root and affect the growth and development. Especially in winter, it must be strictly controlled.
A layer of basal fertilizer was applied before potting, and then compound fertilizer was applied every 10 days during growth.
