Thanks to the efforts of breeders, there are currently a number of varieties of roses that have high frost resistance, so they can not be sheltered for the winter. But still, most roses need to be "hidden" from frost so that they do not freeze.
How to do this correctly, what materials and designs to use, the nuances of this procedure in different Russian regions will be discussed in this article.
Why cover the roses?
This procedure should be carried out because during the cold winter, the delicate root system of shrubs, as well as branches with flower buds located on them, can be damaged from the cold.
Most often, instead of damaged or frozen flower buds, new young shoots will appear new. But the frozen root system of rose bushes is most often not restored, which leads to the death of the entire bush.
Therefore, sheltering roses before the onset of cold weather is an event that helps these flowering shrubs calmly survive severe frosty winters.
What plants require shelter?
Although it is believed that there are frost-resistant varieties of roses that do not require shelter even in severe winters, nevertheless they also need to be prepared for the onset of cold weather in a special way.
And you must definitely cover the following types of flowering shrubs:
- ground cover;
- hybrid tea;
Such roses can not be covered for the winter only in the south of Russia, where winters are mild, and temperatures rarely drop below -3-5 ° C.
What varieties do not need to be covered?
You do not need to cover some varieties of park roses, as well as separately bred hybrid varieties, but even they need auxiliary shelter. Varieties of Canadian roses winter well, covered only with a layer of snow. But it happens that the upper stems of such varieties can freeze, but over the summer period these flowering perennials have time to recover.
How to prepare roses for shelter in the fall?
Before the immediate shelter of flowering shrubs with special materials, some activities are carried out to prepare flowers for the winter:
- In the second decade of September, it is necessary to introduce complex mineral fertilizers containing phosphorus and potassium in all of the near-stem circles of roses. You can make dry preparations in the soil, covering them during digging, or make liquid solutions of such top dressings in the soil.
- About a month before the procedure for sheltering the shrub, you should cut off all the flowers and foliage, preparing blooming perennials for the onset of dormancy.
- All stems need to be trimmed by about 0.5 m - it will be easier to cover the bushes. All places of cuts need to be treated with a special composition (or use a garden var).
- The stems from which the foliage is harvested are treated with copper sulfate. But can be used for processing plants Topaz, Oksikhom or Coming soon.
- All tree trunks should be cleaned of plant debris, remove fallen leaves, as pests can hide in them for the winter.
- The root system of the bushes should be sprinkled with garden soil or river sand.
- Long shoots gently bend to the surface of the soil and secure with special brackets.
IMPORTANT! In the autumn period, these flowering perennials can not be fed with fertilizers containing nitrogen. After all, this element provokes an active growth of the vegetative mass, and young shoots do not have time to ripen to frost, they will surely freeze in the winter, and besides, their unforeseen growth will weaken the bush.
How to hide roses for the winter: step-by-step instructions
The algorithm of such a procedure consists of the following activities:
- shoots bend to the ground, laying on special supporting materials, or cut at least 1/3;
- then the base of the bushes should be spudded with a layer of garden soil, the thickness of which should be at least 18-19 cm;
- impose a layer of dry leaves on top, which are pressed with fir branches.
What designs are used to cover plants?
Typically, to cover these perennial shrubs, various types of frames are used - from iron rods, large flowerpots of plastic, wicker baskets, boards, pallets made of wood. From above, such constructions are covered with a non-woven cloth, film, fir branches, straw or dry leaves.
How to bend roses?
So that the lignified shoots do not break when bent, a similar procedure is carried out gradually. About 18-20 days before the onset of frost, shoots are laid out on a special grid. Then it needs to be lowered a little. As a result, the shoots are gradually bent.
How to cover flowers for the winter?
To cover these plants before the onset of the winter period, artificial or natural insulation is used. It is permissible to use several types of insulation at the same time. Such materials are required to possess the following qualities:
- they are durable and resistant, do not respond to negative climatic conditions;
- moisture permeability to protect perennials from shedding;
- easy to use, easy to purchase;
- have durability that it was possible to use them repeatedly.
Spunbond (non-woven fabric)
In recent years, Spanbond is the most popular of all non-woven insulation used to cover perennial flowers, in particular roses. This material is breathable, practical and durable, not subject to mold, safe and affordable.
It can be fixed on a wooden or metal frame, or provide covering the bushes with an air-dry method, tying the material at the base of the bush bushes. Typically, such material is folded in several layers before the procedure.
Shelter with fir branches is most popular with modern gardeners, because they can be found in any forest, the material is breathable, traps snow during the winter, therefore it is used in areas where thaws often give way to severe frosts during the winter. You can also use spruce branches as an addition to non-woven insulation or polyethylene.
Fir branches previously require drying. You can not cover plants with damaged branches with traces of diseases.
Such covering structures may be metal or wood.
The iron rod is bent in the form of an arc, the ends are buried in the soil, and after the start of the winter period, heaters are pulled. If necessary, the material near the ground is reinforced with stones.
A similar construction of wooden bars is also being prepared.
These flowering perennials are also covered with straw with the onset of winter. It serves as an excellent thermal insulator, however, it has a number of negative qualities:
during the thaw period, the straw becomes wet, cakes, begins to rot and mold;
this material practically does not let in sunlight, therefore in the spring the soil warms up more slowly, as a result of which vegetation is delayed;
in winter, rodents often hide in this shelter, which can feed on the roots of the bush. As a result, plants are severely damaged and may die.
Sacking is one of the most accessible covering materials, although the natural version of such a shelter is less and less common. In recent years, gardeners are increasingly using synthetic burlap, which protects plants from frost, but does not allow air to enter.
But natural burlap is also not ideal: it absorbs moisture well, and freezes during the frosty period. As a result, such a heater will not save the rose bushes from the cold. An old burlap from under vegetables, used as a heater, can cause mold or fungal diseases on the vegetative part of the flowers.
If there are no other covering materials at hand, rose bushes can be covered with five-liter bottles. They are cut in half, holes for ventilation are made in the walls, inside peat should be poured.
Features of sheltering different types of roses
Depending on the varieties of these perennials, the types of their shelter also differ. How to cover various roses will be described below.
These varieties of rose bushes are among the most resistant to frost, so it is generally believed that they are not necessary to be covered for the winter. But it is better to cover the newly planted bushes before the onset of frost as follows: cut the shoots 1/3 of the length, before the onset of frost, cover them with garden soil and cover them with peat, the thickness of this layer should be at least 16 cm.
The main thing when sheltering this flowering shrub is to protect the grafted part of the standard roses from the cold. First, the bush is wrapped with spanbond, which is folded in several layers. Then the boom is neatly bent to the soil, but you do not need to break the plant. Then the crown is covered with fir branches, then with dried leaves, which are also covered with fir branches from above.
Shrub species of roses shelter no earlier than the last decade of October.
But the specific timing of such a procedure depends on the weather conditions in the region - if it is too warm, then under the covering material the plants will begin to develop, while at the same time they will melt. As a result, the roots may begin to rot.
Therefore, covering works begin to be carried out when the temperature in the region is below -5 ° C for more than a week.
Before the onset of winter, these roses must be pruned, leaving shoots no more than 24 cm long. Then the bushes are sprinkled with a layer of soil or peat. In winter, you can rake snow on the bushes.
Such varieties of rose bushes do not require additional shelter - the amount of snow that falls during the winter is quite enough for them. However, in severe winter periods, when there is little snow, you have to cover small bushes with non-woven material or fir branches.
What to look for in different regions?
When carrying out covering work in different regions of Russia, it is necessary to pay attention to some nuances - in particular, at the time of the beginning of a steady cooling.
In the middle lane and Moscow region
In the midland and Moscow region, sheltering rose bushes is carried out in the second decade of October. Preliminarily, all the stages of preparing the plants for winter are carried out, then they are covered with special constructions, and non-woven material is pulled from above. The variegated varieties of roses need to be covered with the help of special tunnels. It is enough to cover park roses with fir branches.
In the south of Russia
In the southern Russian regions, these flowering perennials are usually not covered, since winters in these areas are quite warm.
In Siberia and the Urals
Although winters are rather severe in Siberia and the Urals, rose bushes in these regions do not require too complicated shelter. Enough truncated circles of this shrub to close with a layer of mulch with a thickness of 20-25 cm, and lay spruce branches on top. When the snow falls, it is buried on covered rose bushes.
In the event that winter is expected to be cold and snowless, dry air shelter should be built on top of the spruce branches.
Rose bushes not in all Russian regions require mandatory shelter for the winter. But in order to provide them with protection against too cold winter periods, it is necessary not only to cover plants before the onset of cold weather, but also to conduct preliminary preparation of the bush for winter.
Subject to all agrotechnical measures, the “Queen of Flowers” perfectly tolerates the rest period. And with the onset of spring, it is actively growing and will delight the hosts with abundant flowering throughout the summer season.
