1. Watering

Catharanthus roseus itself is afraid of waterlogging. Even if there is a demand for water in spring, do not water too much. It is generally watered every three to five days. In addition, if there is more rain, waterlogging needs to be drained

2. Temperature

The most suitable for Catharanthus roseus is 15 to 20 degrees. Generally speaking, it can meet the requirements. At the beginning of spring, pay attention not to be lower than 10 degrees. However, this is the minimum. If you want the plant to grow rapidly, it's better to have a slightly higher temperature

3. Fertilization

Fertilize once a month and pay attention to the appropriate amount. Because it is close to flowering, some phosphate and potassium fertilizer can be used

4. Change Basin

Changing pots is generally once to twice a year, which is more appropriate in spring. It is better to choose sandy soil that is easy to drain and breathe, rather than saline alkali soil. While changing the basin, you can also trim it

5. Reproduction

Spring is also a good time for breeding. It can be in May. It can be sown and propagated, or strong branches can be selected for cutting propagation< a>
