Is Yushu in the northern temperate zone and what is the minimum temperature for Yushu hardy

Hehe, I don't know if you asked the Qinghai Yushu that happened **. If yes, as follows:

From the perspective of global temperature, Yushu is located at about 33°N, between the Tropic of Cancer at 23°26 N and the Arctic Circle at 66°34 N, so it is located in the North Temperate Zone.

From the perspective of China's temperature zone division, Yushu is located on the Qinghai-Tibet Plateau and belongs to the Qinghai-Tibet Alpine Zone.

Yes, the northern temperate zone, which belongs to the highland mountain climate.

Yushu. The minimum can tolerate a low temperature of about 5 degrees, and if the temperature is too low, frost damage will occur, and the temperature should be kept at about 15 degrees during winter maintenance, and provide all-day sunshine to allow the plants to photosynthesize.

To improve its own cold resistance, and to propagate jade trees mainly use old leaves, young shoots cuttings, select mature hypertrophic leaves or thick top shoots to insert into the soil, to maintain soil moisture.

Yushu can tolerate a minimum of about 5 degrees of low temperature, like a dry, sunny environment, not cold-tolerant, the most suitable environment temperature for growth is between 20-30 degrees, keep the temperature not lower than 10 degrees in winter, and need to move to a warm place indoors for maintenance at 7-10 degrees.

The ambient temperature of Yushu overwintering is best kept at about 15 degrees, it can receive all-day sunshine in winter, synthesize more nutrients through photosynthesis, and can also improve its own temperature to survive the winter safely.

Yushu propagation mainly uses old leaves and young branches together cuttings, in early spring and late autumn can be propagated, cuttings choose old mature with leaf base of the hypertrophic leaves, or grow strong top shoots, with scissors to cut off about 10 cm of branches, after drying obliquely inserted into the soil, the depth of leaf cuttings is 1 3 of the leaves, when the branches are about 2-3 cm, keep the soil moisture, wait for about 30 days to take root.

The jade tree is susceptible to rot disease and anthracnose during the planting period.

and other diseases, suffering from aphids, scale insects and other insect pests, formaldehyde solution can be used when infected with diseases.

or carbendazim suspension, diluted and sprayed on the surface of the plant for disinfection and sterilization, and dimethoate emulsion and dichlorvos are used when suffering from insect infestation.

After dilution, spray to kill insects.

Yushu is afraid of cold and not cold-tolerant, and when the room temperature is lower than 5 in winter, it will be frostbitten, and the room temperature can be stabilized above 10 in order to survive the winter. In winter, the light is softer, and it can be placed indoors in a sunny environment to ensure sufficient light. In addition, it is necessary to wait until the soil is completely dry each time before watering properly.

In winter, the indoor environment is too closed, and it is necessary to open the windows for ventilation in time to ensure air circulation.

Yushu is afraid of cold and not cold-tolerant, Yushu is in the dormant period in winter, frostbite will appear when the temperature is lower than 5, so when maintaining Yushu in winter, the room temperature needs to be controlled above 10 in order to safely overwinter. During the winter dormancy period, you can prune off the overgrown and overly dense branches and leaves of the jade tree to reduce unnecessary nutrient consumption.

Yushu is a light-loving plant, suitable for growing in a sunny environment, in winter it needs to be placed in an indoor sunny environment to maintain, give all-weather natural light, in the northern region when the light is weak, you can use a fill light to supplement the light, to avoid the plant leaves appear to grow long.

In winter, water evaporation is slow, during this period need to reduce the amount of watering, before watering need to observe the changes in the soil, need to wait until the soil is white, need to wait until the soil is white, and stop watering after the soil is wet. And before watering, the water needs to be dried in advance, and the water temperature and room temperature are consistent before watering, so as to avoid frostbite.

Yushu is suitable for growing in a highly ventilated and breathable environment, in winter the indoor environment is too closed, poor ventilation, will lead to a large number of diseases, so daily maintenance, need to open the window in the afternoon of a sunny day, but do not place it in the tuyere for maintenance, so as not to wind the leaves in the cold wind.

Yushu is afraid of cold and is not cold-tolerant.

Yushu likes the sun and likes to stay in a warm and comfortable environment. As a result, it cannot withstand cold weather. Especially in winter, when the temperature is low, Yushu is very prone to frostbite and rot.

Compared with other plants, the jade tree is more sensitive to cold and not cold-tolerant. Therefore, it is recommended to keep it in a warm environment as much as possible in winter when the temperature is low.

As a succulent, the cold resistance of the jade tree is much worse than that of the same type of succulent. Therefore, the daily warmth of the jade tree in winter is very important, and it is recommended that when maintaining it, do not place it outdoors, but try to put it indoors for maintenance.

Since the growth rate of jade trees will slow down significantly after winter. Therefore, you can take advantage of this time to prune its old branches, long branches, etc. Then, apply the wound with plant ash to avoid rotting.

Don't water too often in winter when singing the dough. Try to water it every 20 to 30 days so that the soil can maintain good humidity.

What should I do if Yushu gets frostbitten?

Is it possible to treat the frostbitten jade tree? In fact, the jade tree that was so frozen so badly that the branches and leaves were completely set up, and the branches were wilted and withered. Such a jade tree is completely hopeless, just throw it away, even if it has been raised for a few years or more than ten years, there is no way.

If it is only mild frostbite, such as frostbite only on the leaves, and the branches are relatively tall, it can also be treated. Prune the branches of the jade tree, the leaves of the jade tree that have not yet melted into water, and those with slight frostbite. Then, put it in a place where the temperature is higher than 10 degrees Celsius and wait for it to grow new shoots.

Yushu prefers warm, dry and sunny environments. Not cold-tolerant, afraid of strong light, slightly shade-tolerant.

The soil is preferably a fertile, well-drained sandy loam.

Winter temperatures are not lower than 7.

Before potting, first understand the "growth habit" of the jade tree, and correctly mix the soil, so that the maintenance can be easier.
