What tree is hardy and which tree in the north is not?

Hardy trees are: aspen, yew, whitebark pine, black pine, cedar.

1. Aspen

Aspen is native to the northern hemisphere, and other poplar plants are found higher in the north and are known for their leaves swaying in the breeze and their trunks being very straight.

2. Yew

Yew is also known as yew, red cedar pine, evergreen tree, the whole body is a treasure, the ground is planted up to 25 meters, the world's rare tree species, is the world's endangered natural rare anti-cancer plant, the national first-class protected plant, is a collection of ornamental and medicinal use of a precious tree species.

3. Whitebark pine

Whitebark pine is endemic to China, distributed in Shanxi, western Henan, Qinling in Shaanxi, southern Gansu and Maijishan in Tianshui, Jiangyouguanwu Mountain in northern Sichuan and western Hubei, and cultivated in Suzhou, Hangzhou, Hengyang and other places. Whitebark pine is a light-loving plant and has a certain degree of cold tolerance. But I am very afraid of waterlogging, and when watering the whitebark pine, I should do it in moderation, not too much.

4. Black pine

Black pine, also known as white bud pine, is an evergreen tree that can reach a height of 30 meters and has grayish-black bark. It blooms in April, with a single flower, and the female flowers are born at the top of the new shoots, which are purple in color, and most of the scales (carpels) overlap and are arranged in a spherical shape.

5. Cedar

The leaves are needle-shaped, 8-60 cm long, hard, grayish-green or silvery-gray, scattered on long branches and clustered on short branches. Cedar is light-loving, cold-tolerant, heat-resistant, sand-tolerant and arid climate, and has strong adaptability to soil.

Various varieties of pine trees, cypress has the strongest cold resistance, heavy snow pressure green pine, green pine is straight and straight, it is said that pine and cypress are not afraid of the harsh environment, thrive,

Hello everyone, I'm Huahua. The tree species cultivated in the north need to choose cold-resistant varieties, and the cold-tolerant varieties cannot be planted in the north, because as long as the temperature is low in winter, the plant will freeze to death, and the cost of breeding is relatively high, so you can only choose cold-resistant varieties in the breeding, the subject wants to know that some of the trees in the north are not cold-resistant, probably to avoid careless planting, if you also want to know, just take a look at the flowers.

1. Trees of non-cold-tolerant species.

Fig tree. Huahua's family planted a fig in the yard, but one year the temperature was particularly low, because I forgot to do cold-proof measures, causing it to freeze to death, the next spring was stunned and did not sprout, so Huahua felt that this kind of tree is still not very cold-resistant, although the temperature in winter is low in Shandong, it is also OK, and the fig tree at home also needs to be cold-proof, and then it will not work further north, and it is very easy to freeze to death.

2. How to keep trees out of winter when the temperature is too low.

In the north, the slightly less cold-tolerant trees planted outdoors need to be cold-proof, the most common is to wrap warm grass curtains or cotton carpets, and some parks are directly enclosed with tarpaulins, so that the plants can be slightly colder in the tarpaulin, in fact, the plants themselves also have their own way of winter, that is, there will be fallen leaves, in fact, in order to reduce the loss of water, it is also a way to adapt to the environment.

3. What problems do not cold-tolerant trees need to pay attention to in winter?

The most important thing to pay attention to in winter is the problem of watering, thinking that the temperature is low and the watering is easy to freeze the plants will freeze, so the watering needs to be carried out at noon in good winter weather, if the local precipitation.

If it doesn't rain or snow often, you need to water it every month or more, but you must pay attention to it at noon, generally not cold-tolerant trees are planted in the south, so don't plant trees in the south.

Bauhinia, begonia, meadowsweet, knotted flowers, and Korean white forsythia are not cold-resistant, and the temperature requirements are relatively high, and they are particularly easy to be frozen, so in the northern winter, we must do a good job of anti-freezing measures for these trees, and do not freeze.

Willows are certainly not hardy, generally willows sprout in the spring, so when autumn they lose their leaves very badly, and in the winter they can't grow at all, and only in the next year will they sprout again.

Conifers include Pinus sylvestris, Pinus nigra, Picea sylvestris, Korean pine, Juniper, Sandy cypress, etc., and arbors include silver poplar, sugar maple, elm, willow, weeping willow, poplar, birch, etc. Moreover, these trees also have a certain greening effect, are not difficult to maintain trees, and the adaptability is very good, which is more common in some areas of northern China.

Cedar. Cedar is particularly intolerant, it is less resistant to wind, and it will be put up with wind barriers every winter.

Cedar, and when this plant arrives in winter, it needs to be artificially wrapped in a layer of anti-freezing equipment, otherwise it will freeze to death in winter.

The species of trees that are both hardy and valuable in the north are as follows:

1. Acer truncatum.

The tree is beautiful, the leaf shape is very beautiful, the color of the young leaves is red, and the autumn leaves turn yellow or red, which is a famous autumn autumn view of the red leaf tree species. Acer truncatum is shade-tolerant, likes cool and humid climate environment, has strong cold resistance, does not have strict requirements for soil, and has fewer pests and diseases.

2. Eucommia ulmoides.

It is a relatively precious traditional Chinese medicine tree species, which is mainly distributed in the northwest region of China.

It has good economic value and is called "plant**". Eucommia ulmoides does not have high requirements for soil, is very easy to manage, extensive management, and does not require much energy to manage.

3. Oak trees in the northern region.

It is widely planted and is a very common tree species, mainly distributed in the Inner Mongolia region of China. The roots of the oak tree are well developed, very windproof, and the vitality is relatively tenacious.
