When can I cut the grass?

Petunia is not only colorful flowers, but also very rich in color, whether used in flower beds or family pot cultivation, is a good choice. Petunia has a strong ability to reproduce and germinate, grows very fast, and more importantly, its florescence is also very long, so it is very suitable for viewing. Just imagine, in the blooming season of petunia, surrounded by petunias, what a pleasant mood it will bring us!

Many flowers and plants can breed young plants by cutting, and cutting can be divided into leaf cutting, stem cutting and root cutting and so on. So, can petunia be cut? If so, when is it suitable for cutting? This also needs to start from the conditions of flower and plant cutting.

The cutting process of flowers and plants is actually a process of asexual reproduction, mainly through different organs and tissues of plants as cuttings, which is a common means of cultivating young plants. Cutting should not only have the objective conditions suitable for growth, such as temperature, humidity and soil quality, but also have the function of cutting germination.

First of all, in terms of objective factors, we need to create a suitable basic environment for cutting germination and growth of petunia. The temperature should be kept between 20-25 ℃, the soil moisture should be kept at about 50%, the air humidity should be kept at about 75%, and the light should be kept at about 30%. In the case of light, temperature and medium conditions are satisfied, as to whether cutting can be carried out, the rest is mainly to see whether Petunia has the function of cutting propagation.

Through practice, it is found that petunia can be cut under suitable external conditions. As the petunia has a very strong germination ability, the original as long as the temperature is suitable, basically can be cut throughout the year. However, there are some requirements in the selection of cuttings. Usually, after the adult petunia blossoms, the shoots at the top of the plant should be cut off as cuttings, and the length should be kept at about 10 cm. After cuttings, if the maintenance conditions are met, they can generally take root in 2-3 weeks, and can basically be potted and transplanted after growing for 1 month.

However, in the outdoor natural environment for cutting, in addition to the preparation of nutritious soil, it is also necessary to meet the conditions of temperature and humidity. According to its germination conditions and growth requirements, cuttings can only be carried out in spring and summer, because the objective conditions can be more satisfied in these two seasons. Therefore, the survival rate of cuttings is relatively high.
