Which tree in the north is not hardy? What are the hardy and valuable tree species in the north?

Hello everyone, I'm Flowey. 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, that 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 come and see 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.

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.

5. Beech trees. It is a tree species with very strong vitality, which has good ornamental property in autumn and winter, and the vitality is very tenacious, and the bud growth rate is fast.

Hardy trees are plum blossoms, birches, larch, cedars, and winter cherry blossoms.
