How does the mimosa survive the winter?

Mimosa is a kind of flower that will be put away as soon as it touches the leaves, just like a little girl. It is very interesting to raise it. How does the mimosa survive the winter?

First, how does the mimosa spend the winter?

1. Watering requirements

The shy prairie comes from tropical flowers and plants that like to be humid. It likes a warm and humid environment. In summer, it is necessary to keep the basin soil moist and not too dry. In winter, it is necessary to reduce the amount of water to prevent frost damage.

2. Soil requirements

Mimosa does not have high requirements for soil, and most of the soil can meet its needs. However, it is recommended to choose a loose and fertile humus mixed soil, because the good permeability of this soil is helpful to its growth.

3. Lighting requirements

Mimosa likes light and should be placed on the sunny windowsill for maintenance in winter. Lack of light can easily lead to the yellowing and wilting of mimosa.

4. Temperature requirement

It requires a high temperature. In winter, the temperature should be maintained above 10 degrees. The low temperature plants below 10 degrees will die. In the depths of winter, you can move it indoors and keep away from air conditioning and heating. Of course, it can also be planted in a greenhouse, or a layer of plastic film can be added to the root of mimosa, and the temperature can be adjusted by some warming equipment.

5. Fertilizer requirements

Mimosa is not particularly strict in fertilizer requirements, we can give it thin fat water every ten days or half a month, so that it can meet its needs.

Second, why is the mimosa shy?

The main reason for the shyness of mimosa leaves is a physiological phenomenon, and it is also the result of long-term adaptation to the external environment in the process of phylogeny. Because the shy prairie is produced in the tropics, where there are many strong winds and torrential rain, when the storm blows the leaflets, it immediately closes the leaves to protect them from the storm, thus gradually forming this physiological phenomenon.

At the base of the petiole of mimosa, there is an inflated organ called "leaf pillow". There are many parenchyma cells in the leaf pillow, which are highly sensitive to external stimuli. Once any part of the mimosa is touched, the stimulation will be transmitted to the leaf pillow. After the leaf pillow receives the signal, the cell sap in the parenchyma cells begins to flow to the intercellular space, which reduces the expansion ability of the cells, and the pressure between the cells in the lower part of the leaf pillow decreases. As a result, the leaf closes and the petiole droops. After 1-2 minutes, the cell fluid gradually flowed back to the leaf pillow, so the leaves returned to their original appearance. This is why the mimosa closes.
