Conifers, features of their wintering
When caring for conifers, it is important to remember that young specimens are sensitive to temperature fluctuations. This is due to the fact that the roots of the plant are too close to the surface.
That is why, when leaving, it is recommended to mulch the root areas without fail. It is recommended to do this only until the plant gets stronger.
During the wintering process, the needles do not crumble, providing the plant with water and protecting it from the cold. The wax coating of the needles helps the trees to protect themselves from hypothermia and unnecessary water loss. Thus, wax is a kind of protective film.
A mature tree retains its bright green color even with the onset of frost, when the root areas are covered with a layer of ice. During this period, additional care is reduced to cutting off excess branches.
Which tree drops needles for the winter
Although conifers are considered evergreen, the effect is achieved by a gradual change of needles - the old ones fall off, new ones grow in their place, and this does not happen during a particular season, but during the year. Nevertheless, several representatives of conifers behave in the likeness of deciduous plants, shedding their leaves-needles in the fall.
It is also common for larches to completely change their green dress every year, dropping needles in the fall and overgrowing with new ones every spring. The new needles are very delicate and soft, despite the fact that the wood of the tree is unusually hard.
Larch is a tree that sheds its green clothes every fall. Despite the fact that the needles of this plant are very soft, the wood is considered one of the strongest in the world.
Like deciduous representatives, larch needles by autumn begin to turn yellow and fall off completely. By the spring period, the branches are overgrown with green needles in the process of increasing growth.
This property has developed in the plant as a result of the plant's adaptation to cold climates. Thus, larch minimizes energy waste in winter.
In addition to larch, there are several other plant species that shed their leaves when the temperature drops. However, this tree is the most widespread and famous.
When larch sheds needles, features of plant wintering
Larch, which belongs to the few conifers that shed needles for the winter, lives on average from 350 to 400 years. Some species can live up to 500 years.
Unlike other conifers, larch needles are not hard and sharp. Soft to the touch, easy to break, outwardly they resemble ordinary thin and flat leaves.
The features of plant wintering include:
- Leaf scattering begins at the end of September. This feature allows the species to spread north of other large trees;
- Dropping needles for the winter helps the plant to protect itself from drying out, which threatens many conifers when the soil freezes;
- For the winter, the tree goes into a kind of hibernation, all processes in it slow down and return to normal only by spring.
Wintering features help the plant to survive the most severe cold weather. If conifers can die as a result of excessive evaporation of water through the needles, then larch tolerates a cold snap without much harm to itself.
Is the only coniferous tree that sheds needles for the winter, other deciduous
Despite the fact that larch is considered the most famous and widespread tree that sheds needles for the winter, there are several other types of deciduous conifers.
The first is Metasequoia, which is a coniferous plant; it belongs to the cypress family.
The features of this plant include:
- Most of the representatives are distributed in the area of Hubei province;
- The average height of the tree is 35-40 m, the cut diameter is 2 m;
- The branches are located opposite, form a wide-conical crown;
- May be over 600 years old;
- Distributed on mountain slopes, along riverbeds and on the edges of hollows, where it forms mixed forests;
- Differs in ease of reproduction and growth rate. Thanks to the latter, it develops rapidly, both when propagated by cuttings and by seeds;
- Unpretentious to soil conditions and temperature fluctuations, although it feels best in countries of humid subtropics.
This relict genus contains several species. Hanging cones of matasequoia with thyroid woody scales.
Another representative of deciduous conifers is the taxodium two-rowed or marsh cypress.
The characteristic features of these large trees include:
- Widespread in the swamp regions of the United States from Texas and Florida to Delaware;
- Reaches 35-45 m in height;
- Narrow and long leaves are arranged in several opposite rows and reach 1.3-1.9 cm in length.
An interesting feature of the taxodium is the fact that regular over-watering causes the lower part of the trunk to expand. As a consequence, the development of pneumatophores, outgrowths that rise above the soil and water.
Distributed in swampy areas for additional anchorage in the soil.
Dropping needles for the winter is a characteristic feature of some genera. One of the most common representatives of this group is larch.
Dropping the needles helps the larch to endure the sharp cold snaps of the winter period as painlessly as possible.
