What if the leaves of Catharanthus roseus are curled and curled?

Catharanthus roseus is of ornamental value because of its evergreen seasons, various flowering and long flowering period, especially as a potted plant. As long as we pay attention to conservation and management, we can generally blossom in spring to autumn, so Catharanthus roseus has also gained a good name every day and spring. And there are many varieties of Catharanthus roseus, and they are also very adaptable to the environment, so if you pay a little attention, you can easily blow it up. However, sometimes, perhaps because of poor management and other factors, it will often lead to Catharanthus roseus leaves curling, curling and other phenomena. What's going on?

Catharanthus roseus has the characteristics of high temperature, humid and hot growth environment, but also has a certain ability to tolerate shade, but it is not resistant to cold. The best growth temperature is 20 ℃-33 ℃. Although it is resistant to semi-shade, it also likes light, and although it likes moist, it is also afraid of waterlogging. Therefore, in the usual management process, we should maintain according to its growth habits, otherwise the leaves of potted Catharanthus roseus may appear curling, curling and other bad growth phenomena, which will seriously reduce its ornamental value.

Practice has proved that the phenomenon of leaf curling and curling of Catharanthus roseus is often caused by the following factors.

First, the leaves curl upward

If the leaves of Catharanthus roseus curl upward and show a cup shape in the process of conservation and management, it is often due to excessive light or too much water loss. In this case, it often happens in summer. Although Catharanthus roseus prefers hot and hot weather, if the hot sun is exposed for too long in midsummer, the plants will lose water excessively because of the strong light, so the leaves will curl upward.

If the summer light is too strong, the necessary shading measures should be taken in time, and the potted plants can be moved to the shade of the big trees; and if the potted soil is too dry, it should be watered in time to maintain the water needed for plant growth. However, if it is hot and hot in summer, it is recommended to avoid watering during the high temperature period during the day and carry out it in the morning and evening. At the same time, you can also spray more water to cool and moisturize.

Second, the leaves curl downward

If it is found that the leaves of potted Catharanthus roseus curl downward and show a cup shape, it is probably due to the low temperature in the current plant growth environment. After all, Catharanthus roseus is a kind of plant with poor cold tolerance, when the temperature is too low, the plant will show a state of self-protection, and often show in the way of curling leaves.

The most suitable growth temperature of Catharanthus roseus is between 20 ℃-33 ℃, and it likes light, especially in winter. In order to keep the plant growing well, it is necessary to provide sufficient light for it in sunny days. But for winter, keeping warm and keeping out the cold is often more important, especially the need to control water in time, otherwise the plant will be easily frozen in winter. After all, Catharanthus roseus likes warmth, so you should not let the temperature below 10 ℃ even in winter, otherwise it may cause plants to freeze and make the leaves curl down and other poor growth phenomena.

In view of this situation, we need to move the potted plants indoors for maintenance in time, at the same time, take measures to keep warm and keep cold, and adjust the indoor temperature to more than 10 ℃, so as to ensure that the plants will not be frostbitten and provide a guarantee for their safe and smooth winter.
