Precautions for repotting Catharanthus roseus

1. Repotting during the seedling stage

Generally speaking, Catharanthus roseus is mainly cultivated as a perennial for more than one year. In the early stage, it is usually planted in a small pot. After it grows older, it is gradually transplanted into a large pot and the pot is changed at this time. Be careful not to let the soil in the pot be too wet. Choose slightly dry soil and remove the original soil ball as much as possible to avoid damaging the roots or minimize root damage and replant.

2. Repotting during the growing season

If you want to change the pot during the growing season, the time is usually chosen in spring from March to May. When repotting, be sure to take out the soil ball and process it. Remove the soil on the surface of the soil ball, trim off the old roots and curled roots underneath, and dry it in the sun or apply disinfectant.

Pruning is necessary after planting, because the roots are damaged and there is not enough water to absorb, so apply less water. When pruning, use the short-cut method, cut off a piece of the upper branch and leave 3-4 leaves at the bottom.
