Succulent frostbite mostly occurs in the southern region, because many southern friends are exposed even in winter, and northern friends may not understand, that is because many cities in the southern region are not lower than 0 all year round or even several years Therefore, many cities in the south have open climatic conditions, and the weather in the south is uncertain, the low temperature is temporary, and the temperature will come up again after a whileWhere can I put it?As for the protective measures, according to everyone's feedback, it seems that a simple covering film does not seem to have much effect when it is below -5. To be like the northern meat friends, there is a heated indoor or a greenhouse with circulating heating, and our southern meat friends are beyond the reach of the dust.
If our exposed succulents are unfortunately frostbitten, how should we take care of them?Here are a few key points to keep in mind:
The first point:Succulents frostbite do not immediately move the succulents to a heated or air-conditioned room, because the sudden change of the environment and excessive temperature difference will cause the self-regulation function of the plant to be disordered or even completely collapsed, animals and plants are the same, biology calls this stress disease, but many species of animals and plants have gained better adaptability in the process of evolution to overcome environmental changes, obviously most succulents are not in this list, because many unfortunate succulents die of the cause of death is also due to stress disease.
The correct way to do this is to move the frostbitten flesh to a well-lit place where the temperature is 5 or more and there is no rain or snow and shelter from the wind, and then slowly transition to higher temperatures and stronger sunlight. Note that ventilation is not so important for succulents at this time (at low temperatures), and if you struggle with ventilation at this time, a cold wind may pass and the meat will be frozen.
The thawing of succulents that have been frozen, if it is not serious, can be thawed naturally at room temperature. For those who have a super low temperature overnight and the meat has been deeply sealed in the ice and snow, you can use cold water at room temperature (do not use hot water, the consequences of using hot water are the same as suddenly putting it into a high temperature environment), until the covered ice and snow are dissolved, and then according to the previous conventional method of maintenance. This method is limited to areas with ultra-low temperatures overnight, and is limited to meat sealed in thick snow and ice. Because of the specific heat capacity of water, if you thaw it in the usual way, the snow and ice will take away a lot of heat in the process of dissolving, and at the same time, it may worsen the frostbite of the already frozen meat. Therefore, protection after snow is even more important. Many succulents that die from frostbite do not die when it snows, but after the snow melts, so you must not take it lightly when it snows, especially on a sunny night after the snow, a sunny night after the snow, a sunny night after the snow.
The second point:If it has already started to snow, please always pay attention to the weather forecast and the measured value of the thermometer in every corner, if the temperature continues to cool down in the next few days, do not leave it to chance, timely rescue is very important for the meat, sometimes their life and death are in our thoughts. If the temperature continues to rise and is higher than 0 in the next few days, then you can relax a little, but at the same time, you should pay attention to the measured value of the thermohygrometer to see if the weather forecast has released our pigeons. If the succulents are frostbitten and there is no chance that the temperature will rise in the next few days, harvest them as much as you can, and use your endless creativity to protect yourself as much as possible, at least to ensure that you don't get drenched in snow and cut off water.
The third point:Even if the succulent plant is frostbitten, do not remove the transparent leaves right away and give it a few days to recover. Depending on the species, the degree of frostbite is different, and the time it takes to heal itself is also different. Some people here may say that frostbitten leaves will become a hotbed of harmful bacteria after turning into water, once the rot will be reversed along the plant's nutrient transport organs to infect the whole plant, yes, at first I also thought so, full of several large bowls of transparent leaves, this is all on the third day after my flesh frostbite, in the case that most of the frostbitten varieties have fully recovered, I thought that these two varieties are out of play, I am afraid that the plant will be infected after the frostbitten leaves deteriorate into water, and then pick up the light at night to pick all the transparent leaves.
I'm a very emotional person, and I can't bear to throw away even dead leaves. So there's a chance to see the plucked leaves look like this a week after the cold spell has passed. As you can see, almost all of the Raul leaves, which were completely transparent, have returned to normal. In fact, when I saw this scene, my heart collapsed, so I thought it was broken and made a leaf cutting, and I went to cry for a while. Therefore, don't be anxious after frostbite, in addition to moving to a safe place, give the meat some time to heal itself, maybe it will give you a miracle.
Of course, everything must be reversed, and frostbitten leaves are definitely not okay all the time, if the leaves with deep frostbite really can't recover, next, it will become soft, it will turn into water, and it will become blown. At this time, if you don't remove it, it will really become the nutrient base of various bacteria and molds, and then these invisible little villains will really reverse infect the remaining healthy parts of the plant along the nutrient delivery organs in the plant. Therefore, at this time, you should pay close attention to the changes in the frostbitten leaves, when the leaves become crystal clear, start to soften, and are full of water with a light pinch, you must pick them. At the same time, if the stem is also watered, cut off the stem together (if possible, carbendazim can be applied to the wound to prevent infection). Keep the part with normal color and wait for the beginning of spring, if the whole plant is watered by deep frostbite, it is recommended to at least keep the base and don't throw it away, because succulents will have miracles.
There is also a situation, which is also the sequelae of frostbite, that is, the flesh in the recovery period after frostbite will fall off the leaves for no reason, I only found that the characteristics of Dharma Fu Niang are more obvious, and the leaves that fall off this kind of touch should also be cleaned up in time, otherwise the consequences are the same as the previous one.
Whether it is ornamental plants or ornamental animals, it is very important to read various articles and learn from the experience Xi of predecessors, and it is very important to stand on the shoulders of giants to see further. However, in fact, it is more important to observe and think diligently, and do not blindly listen to the experience of others, because the different regional environment, different maintenance conditions and maintenance Xi habits, and various hidden factors not mentioned in the strategy will become the risk of blind obedience. Therefore, the key to raising succulents is to improve or even surpass the former through their own observation and summary in practice after learning Xi, and it is enough to raise their own succulents.
