How to grow vinca roseus in spring

1. Watering

Catharanthus roseus itself is afraid of waterlogging. Even though it needs water to grow in spring, it must not be watered excessively. Generally water once every three to five days. In addition, if there is a lot of rain, drainage is required.

2. Temperature

The most suitable temperature for vinca roseus is fifteen to twenty degrees. Generally speaking, it can meet the requirements, but be careful in early spring to make sure the temperature does not drop below ten degrees. However, this is the minimum limit. If you want the plants to grow quickly, it is better to keep the temperature slightly higher.

3. Fertilization

Fertilize once a month, but be careful to use the right amount. Because it is close to the flowering period, you can use some phosphorus fertilizer and potassium fertilizer.

4. Repotting

Generally speaking, repotting is done once every one to two years, preferably in spring. It is better to choose sandy soil that is easy to drain and breathable, and avoid saline-alkali soil. When repotting, you can also prune the plant.

5. Reproduction

Spring is also a good time for breeding, specifically in May. It can be propagated by sowing or by cuttings of strong branches.
