How to care for Catharanthus in winter
Let's talk about how to care for Catharanthus in winter and the cultivation methods and precautions of green plants and flowers. Here are the details:
Catharanthus, also known as the evergreen chrysanthemum, has been cultivated into several varieties in Taiwan, and the flowers are also getting larger. Catharanthus is not only ornamental but also a member of Chinese herbal medicine, with good anti-tumor effects. So, how should Catharanthus be cultivated? Today, the editor will share with you the cultivation methods of Catharanthus in winter. Let's take a look together.
1. Indoor care
Usually, Catharanthus is cultivated outdoors to better absorb the public and maintain good ventilation. However, as the temperature drops in late autumn and winter, it is very easy to suffer from low-temperature frostbite if it is placed outdoors again. Therefore, it needs to be moved indoors in winter, while controlling the room temperature above 10 degrees Celsius, so that it can safely survive the winter.
2. Increase sunlight
When cultivating indoors, it should also be placed in a place that can be exposed to sunlight to allow it to receive adequate sunlight, which can help it photosynthesize better. Moreover, sunlight can increase the ambient temperature, making it grow better. If it is cloudy and dark, artificial lighting can be used to supplement the light for Catharanthus.
3. Fertilization and water management
In winter, Catharanthus's demand for fertilizer and water will decrease significantly, so it is important to control the application of fertilizer and water during maintenance. Generally, water it once a week, preferably in the middle of the day when the temperature is higher, with water similar in temperature to the room temperature, to prevent the soil temperature from dropping due to low water temperature, which is very detrimental to plant growth. Before winter, a long-acting base fertilizer can be applied, and then an appropriate amount of phosphorus and potassium fertilizer can be applied to ensure sufficient nutrients for wintering.

4. Pruning branches and leaves
Catharanthus has very dense branches and leaves, so it also needs to be pruned in winter. Mainly, the weak branches and diseased branches at the top of the plant should be pruned, and the overlong branches should be cut, which can prevent excessive consumption of nutrients and save nutrients, allowing it to survive the winter safely.
5. Using a plastic bag to increase temperature
In winter, a plastic bag can be placed over the pot to keep warm, to prevent the cold wind and temperature drop, thus ensuring its normal growth. Alternatively, plastic film can be used to cover it, creating a small insulating greenhouse to keep it from frostbite during the winter.
