Shelter of roses for the winter in the Leningrad region. What to process roses before hiding for the winter?

Rose has always been considered the queen of any garden, and caring for her requires special knowledge and skills. The elimination of frost-resistant varieties made the planting of roses not only a privilege of the southern regions of Russia, but also of the northern regions, where they, with proper care, please the owners for more than one year. The shelter of roses for the winter in the Leningrad Region has its own characteristics, since snowy winter does not always occur, and temperature changes can lead to the death of the plant.

Varieties for the Leningrad Region

Not always planted roses even with very good care are experiencing frost, one of the reasons may be:

• Unsuitable method of distillation. The shrub and rootstocks grown in the greenhouse do not always differ in frost resistance.
• Grade. Park or landscape species are least afraid of frosts and can survive the winter with minimal protection. Tea-hybrids and climbing ones belong to thermophilic varieties, which require the construction of protective devices. Medium-stable - many-faced floribundas and miniature kinds of roses.

Main types of work

The shelter of roses for the winter in the Leningrad region passes in several basic stages:

• Stop feeding.
• Pruning.
• Cleaning.
• Treatment.
• Hilling.
• Shelter.

Each operation has its own characteristics, depending on the climate of the region and the type of rose. The timing of the implementation is dictated by temperature changes at the time of the preparatory work, if the autumn is warm, then shelter can not be sown, with the appearance of sharp frosts below -5 ° C it makes sense to hurry.

Beginning of preparatory work

The shelter of roses for the winter in the Leningrad region begins with the second half of summer. According to the natural calendar, flowers, preparing for autumn, slow down the process of intensive growth, and at this time is strictly prohibited:

• End of July - to introduce fertilizing fertilizers (nitrogen fertilizers).
• The beginning of autumn is to cut off flowers and cut off wilted buds, so as not to interfere with the plant to go through a full flowering cycle.

Any of the above actions can serve as an incentive for creating new shoots, which is highly undesirable before the onset of frost.

In the middle of the first month of autumn, it is necessary to fertilize the bush with potassium-magnesium preparations, providing them with a supply of nutrients for better spring growth.

At this time, it is extremely undesirable to loosen the earth, so this operation can start the process of growing a flower.

By the end of September, leaves on the bushes begin to dry out, and it's time to remove the yellowed foliage. It is necessary to start with sick leaves, at the end of autumn, to the beginning of the shelter, it is desirable to remove all dry leaves, but it is quite possible to confine ourselves to cleaning and burning only the sick shoots.

Trimming

Mandatory activities that provide a good winter and spring flowering roses - shelter for the winter and pruning. The type of work is determined by the plant variety.

Crop must be all the bushes, regardless of age. Are removed:

• Flowers, buds.
• Sick and weak stems, which can not bear frost and die, which can lead to infection of the bush.

After pruning on a bush, depending on its size, no more than 5 main branches should remain, all the rest should be removed. All work should be done only with a special sharp tool, leaving an oblique cut.

The height of shoots left for wintering depends on the variety.

• Frost-resistant park varieties are practically not shortened, only preventive cleaning and cleaning of weak branches is carried out.
• In hybrid-tea, floribunda and other less resistant varieties, a large percentage of the above-ground part is cut, leaving no more than 5 kidneys.

Individual approach requires climbing roses, shelter for the winter and pruning are specific due to long stems, which are practically not shortened. It is necessary to clean only the sick and dry parts, as well as all the foliage.

Having decided the issue by pruning, you can proceed to clear the land cover. Cleaning should be thorough, under the future canopy there should be nothing that could cause rot.

Disinfection and hilling

Many gardeners ask the question: "Than to process roses before shelter for the winter?". There are several solutions:

• The classical version: 5% iron vitriol, or Bordeaux mixture. But for a greater guarantee, preventive treatment should be carried out in the summer, for this many summer residents use "Fitosporin", which gives a good disinfecting effect.
• A simpler method and not always an effective method using ash. The plot of land and wet shoots are sprinkled: one bank of dry ash per 1m ^2.
  

Hilling - a procedure common to many gardeners, in the case of roses, it is desirable to conduct it preferably with sand, after disinfection, since the soil under the bush can contain many different bacteria and fungi. The height of the boulder depends on the size of the bush, on average not less than 20 cm. The loose consistency of the sand protects the root system without forming a crust upon freezing, promoting good ventilation of the underground part of the plant.

Processing of roses before shelter for the winter and hilling is carried out on dry land and shoots. A problem during this period may be rain, a phenomenon not uncommon, especially in the fall. The yield is simple: the use of polyethylene in the form of an umbrella or tent. Cover with it is desirable not only the bush, but also the soil.

Preparing the shelter

It is not recommended to start a full-scale warm-up procedure before reaching -5 ° C (the critical temperature for varieties with low frost-resistant qualities), since too early wrapping can weaken the bush. Most often, the shelter period is the end of October and the beginning of November.

Labor intensity depends on the variety, especially labor-intensive climbing roses, shelter for the winter and pruning takes place with a great expenditure of time and resources, since the branches of bushes are not cut before wintering, they need to be bent correctly. Do this slowly, if necessary, slightly loosen under the bush earth. The branches are connected to a surface pre-covered with straw, lapnik or shields and fixed by holders.

Protection for thermophilic varieties

Special care is required and a climbing rose, shelter for the winter can be realized in many ways, the choice depends on the landing region and the ability of the owners:

Shield. A reliable and time-consuming option, ensuring a high percentage of color survival even in severe frosts.

• Requires the presence of two nails fastened with nails , the length depends on the height of the flower, the width of up to 90 cm.
• Install the structure on top of the fixed branches.
• Drive into the ground wedges to keep the roof from being displaced.
• At the top, place protection against moisture: film, lapnik. Very often there is a recommendation to fill the film with earth, but not all gardeners go for it, being afraid of the appearance of excessive condensation.

The shield is made of wooden boards, it is not necessary to knock them down tightly, the presence of slots is permissible. The main criterion is reliability, abundant snow drifts can break down the structure damaging the whip of a rose.

The skeleton method and strapping are also used.

In the second case, the associated shoots are covered with lapnik and lutrasil, pressing down on the ground with bricks, boards and tarpaulins.

A frequent phenomenon is a greenhouse with different varieties of bushes, among which a climbing rose towers, shelter for the winter in this case will have its own characteristics.

Branches can not be lowered to the ground, they need to be fixed to the hammered posts, and then to make the roof.

Shelter varieties floribunda, tea-hybrid

Most often, the shelter of roses for the winter in the Leningrad region of medium-hardy varieties is performed by an air-dry method.

Dignity: good ventilation, easy to manufacture

You will need to do:

• The basis is the frame. Suitable metal rods or wooden bars and slats. The height depends on the bush, usually just above 50 cm.
• The fence should evenly encircle the whole plant.
• The construction is covered with a heater, fixing it on the frame. Many experts recommend using lutrasil with maximum density, its feature is a breathable structure that does not interfere with air circulation and absorbs excess moisture well. Also very often use lapnik or improvised materials in the form of cardboard, woven rugs, tracks.
• The outer part of the insulation from the rain polyethylene, folded into several layers. At the same time, the ends must remain open.

It is permissible to apply a scheme with two layers of lutrasil and cover the tin without film, avoiding condensation.

The lower part of the heater is to be dug in, for greater reliability, put stones.

Close only the top part of the bush is necessary, the side parts of the heater are lowered at -15 ° C.

And in conclusion

The shelter of roses for the winter in the Leningrad Region should be ventilated, since constant temperature changes lead to the appearance of condensate, which is a beneficial soil for the development of diseases. The snow regions of the region are the most favorable for wintering roses, in the eastern region with low precipitation, special attention should be given to warming, making it maximally ventilated and resistant to frost.
