Hibernation conifers: how to prepare the plants to frost

Without conifer crops does not do any one area. They give a picturesque view of the territory in the winter, when all the deciduous stand bare and beds - empty. Varieties and types of coniferous crops so much that you can create an entire composition, decorative which will be high in any season. But there is a caveat: not all cultures are equally conifers endure winter. If plants were imported from Europe, where the climate is much milder and even Russian Ukrainian - is the probability of severe damage to the crown and the freezing of roots. How to avoid it - will understand more.


How to check the hardiness of conifers?

To reduce the likelihood of winter troubles to zeroIt can be at the stage of purchase seedlings. If you buy arborvitae, spruce, juniper in local nurseries where they grow a few years under the same climatic conditions as in your area, then the problem will disappear by winter hardiness. Weak culture freeze already in the first year after planting in the nursery, so that the shelves simply do not reach.

But more often we get planting materialmarket, where it is impossible to verify whether the precise information about the conditions of growing seedlings gave the seller. And even if all the plants were grown in the local climate - there is no guarantee that they are not overfed with nitrogen fertilizers to accelerate growth. But excess nitrogen significantly reduces crop immunity and leads to freezing.

Therefore, the owners themselves have to see about ephedra, preparing them for hibernation in late autumn.

Dwarf pine

On small plots perfectly coexist different types of dwarf pine, which stands out for its hardiness and ability to withstand snow loads

Among the crops, which more than any other damagedin the winter, leading thujopsis, fir (except the Siberian and Vici) metasekvoi, cypresses and kiparisovniki. In areas with harsh climates this culture is better not to plant, or tune in to the fact that every winter they have to be protected from frost.

In the most unpretentious of coniferous plants, appear:

  • Spruce (except Eastern and Brewer);
  • Cedars;
  • Larch (except Western);
  • Pine (except Thunberg);
  • Junipers (except the Turkestan and Zeravshan);
  • hemlock;
  • Western arborvitae.

The rest of the varieties should be selected taking into account the duration and severity of your winters.

Terms of preparation plant for the winter

Autumn sowing irrigation

Despite the freezing temperatures, lifeprocesses in coniferous cultures are not suspended, but merely slow its course. Therefore, trees and shrubs should be prepared for the winter with this in mind.

Before the onset of the first frost (about the end ofNovember), spend the last abundant watering conifers. Under each culture to pour m 2 buckets of water, but above a meter - from 3 to 5. In this way you will ensure water supply for the plants peredvesennego period. At the end of February, when the sun begins to bake, crown conifer comes to life and requires the supply of moisture and the roots. And if it is not enough in the soil, the frost holds down the ground to a greater depth. Roots can not get water, so needles become dry and easily fired scorching rays.

Especially needed watering:

  • year-old and two-year seedlings, do not develop a strong root system;
  • a rare species with a weak winter hardiness of conifers;
  • plants, which formed a crown and sheared in this season.

If the site has pine trees grown in the art of bonsai or topiary haircut - they require a thorough shelter from the snow

Phosphorus-potassium fertilization

To the young branches of conifers managed to topwinter mature, need to properly feed the plants. Already since August eliminate all the fertilizer, which is composed of nitrogen. He provokes the rapid growth of green matter, and it is greatly weaken the immune system. Useful September add to the soil a mixture of potassium and phosphorus. Thus, you will accelerate the lignification of branches and strengthen the root system.

Mulching young plants

A prerequisite for a healthy winter rarenezimostoykih and varieties of conifers is mulching. Ideal mulch - bark. It is a major, gives the opportunity to come to the roots of oxygen and the temperature is raised does not preclude the extra output vapor from the ground. In this mulching plants never vypreyut, as is the case with sawdust.

Adults conifers or those that were purchased at a local nursery - sprinkle mulch is not necessary. They cope with the winter without shelter.

Bustle in the winter months

If you take into account the previous advice, then, in the winteryour pets will feel quite comfortable, but that care does not end there. Winter weather brings a lot of surprises, and we must deal with them in time.

Surprise one: heavy snow

Sometimes in the winter heavy snowfalls occur. Sleet heavy load settles on ephedra, causing cracks and breaking of skeletal branches thin. If your pet is covered with a sticky and wet snow hat - do not try to shake her, tilting or shaking the branches of the trunk. At this time the bark and branches so fragile that you provoke cracking. It is necessary to wrap the end of the board and a soft cloth to hook it each branch of the adult tree, gently rocking up and down. All branches in range of your growth shakes off a stiff brush or broom, leading from the tip of the trunk.

Kron spherical and columnar varieties cansave, tying it with string. Do not press a branch that does not violate the circulation of juices. Twine must firmly press the crown to the trunk, but not peredavlivat.

Padding string trunk

Drag twine Krona becomes compact and dense, not missing the snow in the middle that makes it through the winter without faults

Surprise two: the icy rain

In contrast daytime and nighttime temperatures branchtrees are covered with ice. It has enough weight, tilt legs and threatening the safety of the plant. Shake off such a beauty you do not succeed, since it firmly sticks to the needles. In this case, it helps out a backup that you used in the summer to support fruit trees. Put them under all the branches that are bent too low to protect against faults. It remains to wait for sunny days to the ice opolz under the rays of its own accord.

Surprise three: gusty winds

In some areas, winter is squallywind. It is not dangerous to stunted dwarf trees or creeping shrubs, but vertical arborvitae, tall cedar or spruce can easily turn to the root (especially on light sandy soils).

If weather forecasters announced a storm warning - insure by putting streamers. They come in two types: with fixing to stakes and anchor type.

The essence of the first embodiment in that the four sidesnear the tree are driven into the ground thick stakes, the height of which more than half the height of the trunk. From each support extends to the trunk splits. His tie is not on the bare crust and pre-wrapped trunk of roofing felt or underlay in place tying wooden brusochek. However, to drive stakes into the frozen ground in the winter does not always succeed, so in this way strengthen the conifers in autumn, especially the newly transplanted large trees.

anchor line

With the help of the anchor extensions can not only save a tree in the wind, but to make it grow vertically

The second type - the anchor - provides installationSteel wires, which are attached at one end to a tree, and the second - on the stretch of the anchor. Anchors should be located outside of the root system. To protect the trunk of a tree became necessary to wind a dense sacking and use wooden laths on top of it.

Surprise four: February sun

Even the most persistent conifers by the end of winter at riskfreeze slightly or, on the contrary, burn. At this time, the weather is unstable, and often days the sun shines so brightly that provokes early awakening roots. They begin to actively feed the crown, expecting fast heat, and there it can descend so-called recurrent frosts. Pause sap flow you can not afford, but can cover the crown of thick non-woven fabric, such as lutrasila, or at least put on young seedlings canvas bag from under a potato.

To prevent imminent thawing earth,Zamulchiruyte its filings. Their white color will reflect the sun's rays, and the roots do not wake up so fast. However, upon the occurrence of a stable heat filings should be removed immediately, so that the plant does not vyprelo.

Coniferous winter

Without shelter lutrasilom or other nonwoven koruna many rare conifers can not stand the test of severe frosts

Another danger conceal the sun's rays, whichburn tender young needles. Therefore, at the end of winter, all yearlings and exotic conifers cover the south shields or completely wrapped burlap crown.

From the sun to protect conifers desirable nonwoven material, since it accumulates heat and can enhance the drying needles.

Shelter conifers

For protection from the sun in February, you can use burlap or agrovoloknom created inside cover dim and soft restraining drying needles

Do not worry if some of the plants in winter needles turn yellow. So juniper and hemlock react to cold. Spring color is restored.

If all the security measures you have spent time - conifers quickly recover from hibernation and will please its decorative.
