1、 What season to sow

Catharanthus roseus is a perennial flower. Generally, it takes one year to take root and needs to grow to a certain size to bloom. Its sowing is generally carried out in spring or autumn. If the conditions at home are good and the temperature is appropriate in winter, sowing can be carried out in autumn. If the temperature is less than 10 degrees in winter, sowing should be carried out in spring

2、 Specific sowing time

The sowing time of Catharanthus roseus is from March to may in spring and from September to October in autumn. In addition, it should be noted that it is best not to sow in advance in autumn, because the temperature is too high, which is very unfavorable to its germination. If you want it to blossom early in spring, you can sow it in the greenhouse in advance
