How to raise a succulent plant in winter
4hw.org: the temperature is low in winter and there is little sunshine. The outdoor meat is not good for the winter. It is easy to freeze to death and frostbite. If there is no heating in the room, it is also very difficult to have more meat for the winter. But do you want to be afraid? Here are a few ways to remedy the frostbite and protect the fleshy winter. You may as well try.
The fleshy frostbite is irreversible. It depends on whether the degree of frostbite exceeds the tolerance of plants. The artificial treatment is very limited. If there are many frozen fleshy stems with black frozen spots, but the top leaves are intact, then the meat can be beheaded and the parts without frostbite can be preserved for cutting. If the whole frostbite can't be recovered after a period of observation, it's almost hopeless.
The chilling injury of succulent plants includes chilling injury and freezing injury. Chilling injury is the harm of low temperature above freezing point to succulent plants, and chilling injury is the harm of low temperature below freezing point to plants. Some meat can't bear the cold injury, let alone the freeze injury. The cold injury will also cause many meat casualties. Under normal circumstances, when the outdoor temperature is 5 ℃, it should be moved indoors. At the same time, when the temperature drops to about 15 ℃, watering should be reduced gradually.
As for the freezing damage of succulent plants, this situation is mainly caused by long-term low temperature or short-term strong cooling, and there will be no situation for succulent plants in a short time after being injured. In the later stage of growth, the frost damage will show slowly, and even the newly grown leaves will have the same frostbite. This kind of succulent plant immune ability decline, very easy to catch mold disease, it needs to increase the sunshine time at the same time, so that the meat is healthy. At the same time, we need to slow down the state of meat. The temperature of about 15 ℃ is the most appropriate, so that the meat has a transition period of temperature will be better.
Direct injury refers to the occurrence of plant lesions within a few hours after being affected by low temperature, indicating that this effect has invaded the cell and directly destroyed the activity of protoplasm. Indirect injury mainly refers to the injury caused by metabolic disorder caused by low temperature. The plant morphology was normal after low temperature, at least five or six days later, the tissue was soft and wilted. However, these changes are caused by the slow changes of physiology and biochemistry after metabolic disorders, not by low temperature.
If you don't pay attention to the weather changes or you just want to abuse the plants and they are frozen through the leaves, take them into the room in time and put them in the place with a temperature of about 5 ℃ for a day, observe the changes. If their leaves become transparent and paddle like, they can be placed in the place with a little ventilation and bright light at room temperature of 10 to 15 ℃, so they are frozen after a few days Transparent leaves will evaporate excess water and become shriveled as new leaves grow, and frozen leaves will be consumed.
If it's a succulent plant placed outdoors, and you don't want or want to move indoors, there's another small way, which is to make a self-made heat preservation space. The easiest way is to cover it with a large transparent plastic film. Don't close completely, leave room for ventilation, or cover each basin with plastic bags. Watering is especially important for succulent plants in winter. By this time the succulent plants had stopped growing. So you don't have to water it often. But if the balcony is very dry, and the basin soil is also dry, you can water it occasionally on a sunny day, without any hindrance.
