Shelter roses for the winter. Shelter climbing roses for the winter
The shelter of roses for the winter is an important and responsible process, which must be approached with great responsibility. Not only their health, external characteristics and flowering time, but also their vitality depends on the proper preparation of plants for wintering.
The main reason for the death of the queen of flowers in the winter is overcooling, as well as sweating and the defeat of various diseases due to non-compliance with the rules for wintering. Improper shelter of roses for the winter and their further death leads to the fact that gardeners refuse to grow flowers and decorate house territories with such beauty.
What is winter hardiness
Winter hardiness - the ability of roses to endure frost and sudden changes in temperature conditions. This indicator depends on the type of plant. Garden varieties of roses, which are intended for cultivation in the open field, are best tolerated by wintering.Greenhouse varieties do not differ in winter hardiness and in most cases die, even if the roses were properly sheltered for the winter.
Among garden roses, they produce more winter-hardy varieties and less resistant to low temperature conditions. The most unpretentious are landscape and park roses, which are better than others tolerate the winter cold.
Of great importance and the size of the plants. The easiest way to cover stunted varieties, including ground cover and miniature than tall, reaching 1.5 m (upright, not fold, climbing).
Preparing plants for shelter in the summer
Resistance to low temperatures depends not only on careful adherence to all the rules of the preparatory process. It happens that even the cover of roses, carried out according to all the rules, for the winter does not save the bush from destruction. This is due to the fact that in the summer season all the necessary procedures for preparing the plants for wintering were not performed.
Think about the shelter of roses for the winter should be at the planning stage of their location. It is necessary to place the bushes so that in the future there are no problems with their preparation for the cold season.
Plant the plants better in rows in such a way that free space is preserved. For park, hybrid tea and floribunda groups, a distance of 30 to 40 cm will be sufficient, and for ground cover and miniature - 20-30 cm.
Preparing plants for wintering
Before the first frost should remove almost all the leaves from the bushes of the plant. Especially carefully recommended to thin out the lower part of the shoots. Shelter climbing roses for the winter involves breaking the leaves in several approaches. It is important to move slowly from the bottom of the plant to its top. This is done in order to stop the evaporation of water from the leaves, as the roots of the plant can not fully work in the frozen ground and independently compensate for the loss of fluid. Plus, the leaves often rot under cover, which certainly leads to the death of the entire bush. The same effects can lead and nevzrevshie shoots, from which you should also get rid of.
Many gardeners recommend cutting the stalks of spray roses to the height of the shelter, while leaving a length of 15-25 cm. This reserve is necessary in order not to damage the grafting sites.You can use the method in which the stems just bend to the ground and secure in this position with metal pins. This method will allow roses to bloom 2-4 weeks earlier than their cropped relatives.
Necessary measures to prevent diseases
Despite the careful shelter of roses for the winter, sudden changes in temperature, poor ventilation and increased humidity can cause diseases. Therefore, before proceeding with the preparation of the plant for the winter, the bush should be treated with antifungal agents. The soil should also be sprayed around, as there may be dangerous fungal spores.
Shelter for the winter ground cover roses
This kind of plants in the cold season can not cover. Most varieties of this group are very hardy. They feel comfortable under the snow cover and do not even shed their leaves until spring. If the winter is predicted to be snowless and very harsh, it is better to do light shelter with lapnik. It protects the plant from the cold wind and provides unobstructed air penetration, thereby preventing rotting.In the spring, on the bushes of ground-covering roses, unbroken leaves are removed and sanitary pruning is performed.
Shelter of park roses for the winter
Before the onset of the first frosts, bushes need to be tucked to 15-20 cm of coarse sand or loose earth. The best insulating material is fir spruce branches. Rose bushes are covered with insulation to a height of 20-30 cm, and on top also with a film, which is sprinkled with earth or sand.
However, a more reliable method of shelter is considered more reliable. It lies in the fact that between the rows are installed boxes or wooden stops with a height of not more than 40 cm. On top of them are closely placed boards or shields. All this is covered with a layer of tar to keep the soil dry. At the ends, the structures are left open, and with the onset of severe frost they are closed with foil or boards.
How to prepare for the cold standard plants
The shelter of standard roses for the winter involves not only warming the trunk and crown, but also the obligatory laying of the plant on the ground. In order to prevent fracture, bend the queen of flowers should be in the opposite direction from the place of grafting. It is first necessary to cut the crown of the trunk.After that, the plant is broken in on one side, the stem is tilted and secured with a metal stud.
Under the crown you need to organize a litter of spruce or coarse sand. Top lay another layer of insulation and cover all the film. For reliability, the latter can be sprinkled with a small layer of earth.
You can not stack shtamb too low, because water will accumulate in the hole, which will cause rotting and death of the shoots.
How to handle curly roses?
The shelter of climbing roses for the winter requires special care and caution, as long plants cannot be damaged. The base of the queen of flowers should be warmed with earth, sand or needles, and then covered with spruce branches. The stems of the plant are removed from the supports and placed on the previously prepared spruce branches. From above, they are warmed by the same lap branches and covered with a film.
If roses create arches and gazebos, weatherization of plants does not require laying lashes on insulation. In this case, the shoots are covered with insulation directly on the supports, and then fixed with ropes.
Lutrasil is a nonwoven fabric.It is used as a heat insulation layer to protect plants during the cold season. Shelter roses with lutrasil for the winter has many advantages. The material allows plants to breathe, which prevents decay in the event of a temperature increase.
It is possible to warm with lutrasil in arcs or without them. However, it should be borne in mind that the higher the arc, the greater the risk that roses will die from frost. Low-sheltered plants will be under the snow, which is the best protector from cold and wind.
If winter is expected with heavy rainfall, a lot of snow can damage the roses, and the shoots will break under its weight. It is necessary to calculate the optimum height of the shelter so that the plants do not freeze and die.
Climatic features of Ukraine
Winter-hardy varieties can not be prepared for the cold season only in the southern part of the country, in all other regions it is necessary to carefully carry out the shelter of roses for the winter. Ukraine has a relatively warm winters and temperate climates. However, some varieties of queen flowers require special care. The shelter of rose bushes for the winter can be done in one of several ways:
-bulk methodconsists in warming a plant with a mound of dry soil or mulch, the height of the shelter can be up to 50 cm above the shoot;
-air dryinvolves the construction of a frame of twigs, which is covered with a film or non-woven material;
-net wrapping(material is used with a diameter of 30-40 cm), in addition the plant is warmed with spruce branches or spruce branches.
No less important and crucial moment is the removal of the shelter from roses in the spring. Even properly insulated plants can die in the spring, if the canopy is removed incorrectly or at the wrong time. When the air temperature increases, the shelter should be removed in stages. First, remove the film, then - lapnik, sand or pine branches, and then free the bushes. The ideal option is considered to be a windless sunny spring day or evening. However, it should be remembered that the plant has been in a humid environment for a long time without exposure to sunlight, therefore, it should be prepared gradually for new weather conditions. All diseased, frostbitten or broken parts are removed from the shoots, and prophylactic spraying is performed.
The cover of roses, made according to the rules for the winter, will protect even the most fastidious varieties from death and disease. In addition, the plants will appreciate the early and abundant flowering.
