What is the lowest temperature that carnations can tolerate?
Today's focus is to introduce the lowest temperature that carnations can tolerate and to understand the methods for overwintering carnations in the aspect of green plants and flowers. Let's get to know more about it.
After watching the news for half a morning, the editor has just opened the document to prepare for today's article. He was originally hesitant about what kind of flower to write about until he opened the flower growth record file and decided to talk about the related knowledge of caring for carnations in winter today. As for why he chose it, it's actually simple, because the editor found that the 4 pots of carnations at home are more cold-tolerant than what everyone discusses online. The editor has not taken any保温 measures to manage them, and they are still healthy and not frozen. Therefore, it seems necessary to specifically explain it to let more people understand it.
Firstly, is it correct that the breeding temperature should not be lower than 9 degrees?
The editor randomly checked the cold-tolerance temperature of carnations before and found that different posts basically answer with 9 degrees. However, the 4 pots of carnations at the editor's home have been placed in a place with temperatures of 5 to minus 5 degrees throughout the winter without any attention, and they have not been frozen or killed by this temperature. Therefore, the editor can still confirm that the cold tolerance of carnations is not as poor as what everyone says online, at least it can withstand the low temperature of minus 5 degrees. And during the recent cold spell with temperatures below minus ten degrees, there were two days when the indoor temperature was almost minus 5 to 8 degrees, and the carnations did not freeze to death. It can be concluded that carnations will not freeze to death in a short time at minus 5 to 8 degrees.
However, although they were not frozen, their growth rate was extremely slow compared to November. Although the buds look much larger than two months ago, they have not yet bloomed even though they have shown color. It can be seen that while minus 5 to minus 5 degrees will not cause it to die, it will definitely cause it to stop growing and flowering. The following picture shows the condition of the carnation buds in November.
The picture below is what the editor took today, and you can see that the buds have grown a lot, and some have already shown color. If the indoor temperature at the editor's home can reach十几 degrees, it is believed that even in winter it can bloom normally. Therefore, as long as the temperature is not consistently below minus 5 degrees for a long time during the winter, it is still possible to ensure that the carnations are alive. However, due to variety differences, some cold-sensitive carnations will freeze at minus 5 degrees. Therefore, for safety, it is advisable to move them to a well-lit indoor area before 0 degrees, and if the temperature is lower than what the editor described, it is necessary to cover the pot with a bag and preferably place the pot in a polystyrene box. If the indoor temperature can be maintained at around 10 degrees at night and 10 degrees higher than at night during the day, then the carnations will not only continue to grow and bloom but also continue to flower.
Secondly, they prefer sunlight, so they need to maintain adequate light in winter
After mastering the temperature, it is actually only necessary to ensure that the location where the pot is placed always has sufficient light. However, it should be noted that carnations are also very prone to etiolation. If you find that the side that is often exposed to the sun is higher than the other sides, you should rotate the pot to allow each side to grow evenly. But remember not to move the location of the pot, because carnations are also very sensitive plants, and frequent changes in the breeding environment can easily lead to stimulation and yellowing of the leaves. If the temperature is up to standard and there is sufficient light, the growth of carnations will be very rapid, and they will bloom more.
Like the editor's home, most of the rooms are facing east, so there is a lack of light. The editor looked at the weather forecast recently, and the lowest temperature is minus 2 degrees, and most of the time it is above 0 degrees, so the carnations were moved to the west staircases, where they can still get sunlight in the afternoon. The picture below still looks a bit elongated, so today the editor turned the shorter side towards the west.

Furthermore, water when dry and be careful not to water the leaf heart
The most difficult part of growing flowers in winter is usually watering, and many新手 flower friends have killed their plants at this stage. An editor friend of the Green Plant Enthusiast website could even kill a cactus, and when he sent a picture to the editor, it looked typical of overwatering, with root rot. Many authors will tell flower friends to water when the potting soil turns white, but this view is also inaccurate. Taking the editor's home as an example, we are in the north, even though I mixed several acidic substrates when buying soil to plant flowers, but because I can't use fruit peel water or other acidic water to water every time, the alkalinity of the potting soil will gradually increase, and the surface substrate will turn white. However, turning white does not mean that it is short of water, especially in winter. Many times, the pot has separated from the potting soil, and when you stick your finger in to test, the potting soil is still moist.
Therefore, the editor waters the carnations in winter as usual by observing the bamboo stakes left in the pot, just like the picture taken today. The editor only rubbed the bamboo stake with his finger and could see a few dust particles on his finger, and there was no dirty stain left by wet mud on the fingertip, which means that the potting soil has completely dried. So you can water it now. Of course, flower friends can also judge by the pot easily.
When watering, in addition to paying attention to using warm water to water in the middle of the day, you should also avoid watering the leaves because the leaf heart of carnations is relatively deep. If the leaves are watered, the water will slide into the leaf heart, and if the water in the leaf heart does not dry in a low-temperature and poor-ventilation environment, it will lead to leaf heart rot. If the indoor temperature is high and the doors and windows are closed, the water droplets on the crowded leaves cannot dry quickly, and red spiders may appear. The picture taken today shows that there are red spiders on the leaves, although their activity is low at low temperatures in winter, it does not mean that they do not bite the leaves. The editor has two pots with mottled leaves. So after taking the picture, the editor flushed the leaves with a lot of water, shook off the water droplets, and placed them in the sun.
In summary, this is the method of caring for carnations in winter, which can be seen to have a certain degree of cold tolerance and will not freeze even at minus 3 degrees, and the leaves are evergreen, but will stop growing and flowering. Therefore, if you want them to bloom in winter, you need to pay attention to temperature control, get more sun, and water less.
