1、 Curing conditions

1. Water: Catharanthus roseus is very afraid of water, so there should not be too much water in the soil, otherwise it will hinder its normal growth. It is best to keep the cultivated soil slightly wet. It is OK to keep it dry in winter. The amount of watering must not be too much. When there are many rainy seasons in summer, you should move to a place where you can't get wet in time 2. Sunlight: it likes sunlight and needs to be raised in a sunny place during maintenance, so that its design and color will be more bright. When you raise it indoors, you need to appropriately move it outdoors and give it enough light 3. Fertilization: during cultivation, sufficient base fertilizer should be applied to the basin bottom, and the fertilizer should be applied every 10 days or so during its growth. The fertilizer can be compound fertilizer or liquid fertilizer. Note that raw fertilizer cannot be used, which will burn the root of the plant

2、 Breeding method

1. Sowing: it can be carried out from March to May. Prepare breathable and drainage matrix, and sow the seeds after disinfection. Cover it with a layer of fine sand and spray water properly. Seedlings will grow in about 7-10 days 2. Cutting: the best time is from April to July. Select the shoots with good growth and cut them into about 5-7cm. Cover the bottom of the branch with a small mud mass, cut in the prepared substrate and give it a growth environment of 20-24 ℃, and small roots will grow in about 20 days
