When the succulent leaves gradually become completely transparent, and the waves wither, some even darken, and there are a few traces of water, and according to the ultra-low temperature for several months, it can usually be judged to be mild frostbite.
The more common feature is that the leaves become loose and fall off, this degree is more suitable to control, just quickly move the plant to a warm place in the room, or preferably cold measures, in fact, to keep the working temperature above zero, the succulent plant will be basically repaired in these two months. There is no way to save the leaves that have been frozen for a long time, and it will gradually wither and rot away. We just need to get rid of it immediately and the succulents will survive the winter safely.
How does a succulent person with severe frostbite manifest itself? Even most of the succulent leaves will shrink and become more and more transparent gray-black, and even the underground stems show signs of withering.
For succulents with severe frostbite, the first step is to move the plant to a warm place, then prune off the frozen leaves, and finally place them in a place of astigmatism. It is best to put the plants in an environment with an ambient temperature greater than 10 degrees, which will take a week. During this period, always maintain a good level of natural ventilation in the environment, do a good job of draining water, and observe the growth and development of leaves.
If it does not solidify again, it is a sign that the succulent is gradually getting better. If the main stem of the braised pork is also frozen, then it is necessary to start the "haircut" and cut it again in a suitable environment. In fact, as long as the succulent root system and the main stem are completed, there is a high probability that the growth can be repaired even if the leaves are severely frostbitten.
Most of the leaves of the succulent plant have also been frozen, and the stems have solidified the level, and the flowers only tell you to throw them away, which is already beyond rescue. Succulents are a painful lesson to us, remember to take precautions before the next winter to prevent this situation from happening again.

1. Pay attention to the weather forecast in time, 2. Reduce watering, 3. Build a greenhouse to keep warm, 4. Keep warm indoors. These three methods can prevent succulent frostbite. Succulents can prevent frostbite through the 4 measures in this article during the winter, and if they accidentally get frostbitten, they can be treated according to 3 conditions.
Of course, prevention is the best cure.
-
Slowly lower the ambient temperature to get the succulents used to low temperature and open raising; Pay attention to changes in the temperature in the area, preferably above freezing, to reduce the chance of frostbite. Pay more attention to the changes in the planting environment, and never "drink the northwest wind";
-
This is to put the flesh in the house when the temperature is lower than five degrees, otherwise it will be easy to get frostbitten.

After frostbite occurs in the succulent, it needs to be placed in an environment of 5 degrees Celsius for a day to determine the frostbite of the plant. If the leaves appear transparent and watery, they need to be transplanted to an environment with a temperature of 10 to 15 degrees Celsius for cultivation, and if the leaves have a large area of frostbite and hydration, it is necessary to depot, cut off the frostbitten part, and then replant.
When the succulent frostbite is damaged, it needs to be moved to an environment with a temperature of about 5 degrees Celsius for a day to judge the frostbite of the plant. If the leaves appear transparent and watery, they need to be transplanted to an environment of 10 to 15 degrees Celsius to ensure a well-ventilated and sunny growing environment.
After a few days of culture, the frostbitten leaves will slowly become shriveled, a large amount of water evaporates, and finally it will become smaller and smaller, as the temperature rises, new leaves will grow, frostbitten leaves will disappear, and after fermentation, it can be used as a base fertilizer for breeding to promote better growth of plants.
However, if the succulent plant is hydrated, and a large area of leaves is frostbitten, it is necessary to cut off the frostbitten part in time to avoid the rotten wound from being in contact with the air, which is easy to be infected with germs and affect the growth and health of the plant.
It is also necessary to cut off the frostbitten part to avoid the ability of the root system to absorb water and nutrients in the soil, which can lead to malnutrition in growth. After pruning is completed, the wound needs to be coated with plant ash or carbendazim solution in time, and wait until the wound is completely healed before planting.

1. Slight frostbite: succulents have traces of frostbite on the leaves, and the obvious feature is that the leaves appear to be hydrated and shrunken, becoming transparent, or even ashed, but some leaves appear frostbite. In this case, as long as the next maintenance environment does not tend to 0 (preferably 10+) succulents will have no problem surviving, and the frostbitten leaves will not recover, and sooner or later they will shrink and fall off.
Wait until spring to repot, cut off the frozen leaves.
2. Severe frostbite: Most of the leaves and even stems of succulents have traces of frostbite, obvious hydration and shrinkage, becoming transparent or even gray and blackened, like this situation is more complicated. If only the leaves show signs of frostbite and the stems are not transparent and blackened, then place the succulents in a 10+, bright and slightly ventilated environment for about a week, do not water during the period, remove the obvious frostbite leaves, and observe slightly, if there is no tendency to hydrate, you can generally continue to survive strongly.
If the stem shows signs of hyalification and softening, cut off the frostbitten stem (be sure to cut it clean, it will spread all the way if it is not removed), apply carbendazim to the wound, and then place it for observation, and wait for a period of time before cutting. If part of the stem already shows signs of frostbite in the first place, remove the frostbitten part and repeat the above steps.

I think it's okay to apply a certain amount of fertilizer and then take measures to protect it from the cold and try not to let it blow cold wind.
-
Don't rush to put the succulent in the house, just put it in a place where the temperature is higher than 5. Don't let it get blown by the wind or get caught in the rain. It takes time to get used to it.
-
At this time, it is necessary to move it indoors quickly, then water it, fertilize it, bask in the sun, and take care of them carefully for a while, and his condition will improve in the future.
If you want the succulent to grow in a good state, you need to maintain a certain temperature difference when it grows rapidly, and the temperature is suitable in spring and autumn, which is the time when the temperature difference is large, and it is a good time to color.
The fire festival is also called the autumn fire lotus, belongs to the sedum family succulents, many clusters, the leaf surface has hairy spots, likes the environment with sufficient sunlight, sufficient light can avoid the plant from growing, make the leaves red, and enhance the ornamentality. The leaves of the plant are oblong, the leaves are full and densely covered with small wart points, and the leaves are not smooth and a little pitted. The leaves of the plants are intersecting and closely arranged. >>>More
