1、 Pot change at Seedling Stage

Generally speaking, Catharanthus roseus is mainly cultivated for more than one year. In the initial stage, it is usually planted in a small basin, and then gradually transplanted into a large basin. At this time, the basin is changed. The original pot should be removed as little as possible and the roots should not be damaged

2、 Changing pots during growing period

If you change pots during the growth period, the time is generally from March to may in spring. When changing the basin, pay attention to the treatment after taking out the soil ball, remove the soil on the upper surface of the soil ball, trim the old roots and curled roots below, and dry them in the air or apply disinfectant

Pruning should be carried out after planting, because there is not so much water for absorption when the root is damaged. Less water should be applied. When pruning, the method of short cutting should be adopted. Cut a piece of the upper branch and leave 3-4 leaves at the bottom
