Prepare pot soil: prepare soft, breathable and humus-rich soil in advance, and the pot size is moderate.
Planting in the soil: If sowing, directly scatter the seeds on the surface of the pot soil and cover them with thin soil. If you plant seedlings, dig a hole and put it in, compact the soil and water it.
Post-management: provide a warm and sunny environment and provide fertilizer and water reasonably during the growing season.
First, planting time
Catharanthus roseus likes warm environment, and has poor cold resistance and high temperature resistance. In order to promote its better growth and easy management, it is best to plant it in spring, and both cutting and sowing can ensure good growth. The specific planting time is from March to April, during which the temperature tends to be stable, which is conducive to growth, seeds can germinate better, and Catharanthus roseus seedlings can adapt to the new environment and resume growth as soon as possible.
Second, prepare the pot soil
Catharanthus roseus has strict requirements on soil. In order to promote vigorous growth, soft, breathable and humus-rich soil must be prepared. When mixing soil, humus soil, peat soil and perlite can be mixed, which can basically meet the demand. Homemade soil must be disinfected before use to prevent bacteria or eggs in it. Or you can buy special soil for planting flowers, which is usually sold in flower shops.
Third, plant underground.
If it is planted by sowing method, prepare Catharanthus roseus seeds with high maturity and full particles, directly sprinkle them on the surface of the basin soil, then cover them with a layer of fine soil and spray water appropriately to keep them moist. In the right environment, the seedlings will grow in about half a month. If you buy Catharanthus roseus seedlings, first dig a small hole in the surface of the pot soil when planting, then put the seedlings in the hole, fill the soil and tamp it, water it, and it will resume growth in a week or so when the environment is suitable.
Fourth, post-management
Catharanthus roseus likes warm and sunny environment. When it returns to growth, it should slowly increase the light and let it bask in the sun. Only when the light is sufficient can photosynthesis be better and flowers bloom as scheduled in the later stage. It has slight drought tolerance and is afraid of waterlogging. It is best to wait until the soil is dry and thoroughly watered, but water is not allowed, otherwise it will easily make the roots retch. There are more nutrients consumed in peak season and flowering period, so it is suggested to apply thin fertilizer frequently to supplement nutrients. Its cold tolerance is limited, so it is necessary to move potted plants indoors after cooling in winter and take measures to control temperature and keep warm.
