How do pine trees spend the winter?

Pine trees are extremely cold-resistant, so there is no need to take wintering measures. There are significant differences in the distribution of pine trees. Generally speaking, Pinus sylvestris var.mongolica. Quercus mongolica and Pinus pentaphylla have strong cold tolerance, so the requirements for heat are not high when planting. However, Pinus tabulaeformis, Pinus bungeana and Pinus densiflora are unique tree species in warm temperate and subtropical high altitude areas, and their requirements for heat are much higher than those of Pinus pentaphylla.

Pinus massoniana, Pinus Qiao Song and Pinus yunnanensis are mainly distributed in the southern region, and their requirements for heat will be higher-a little. Among all pine trees, South Asia pine has the highest demand for heat. In terms of humidity, five-needle pine requires higher humidity than two-needle pine, but it is also closely related to tree species.

Although Pinus armandii and Pinus koraiensis are both varieties of five-needle pine, they have different requirements for humidity, and Pinus koraiensis needs higher humidity. In addition, both Pinus wuweiensis and Pinus densiflora are two-needle pines, and the requirements for moist conditions are still different, which is also related to the geographical location of plant distribution.

Extended data

Pine species:

1 Pinus bungeana

When I was young, I was a little tolerant of the shade. Deep roots, long life, up to hundreds of years. It is naturally distributed in acidic rocky mountain areas with cool climate and grows best on calcareous soil or loess with deep soil layer and moist fertility. The growth temperature range is -30℃-40℃, and it can also adapt to the low temperature of -30℃ and the soil with pH value of 7.5-8.

2. Chinese pine

Pinus tabulaeformis is a positive tree species, with deep roots, light-loving, barren-resistant and wind-resistant. It can grow on acidic, neutral or calcareous loess with deep soil layer and good drainage at -25℃. Heartwood is yellow-reddish-brown, sapwood is yellow-white, with straight texture, fine structure, hard material and durability.
