Rose refers to plants that require care and attention not only in the flowering period, but also in the period of preparation for winter. Rose is a moderately frost-resistant plant, which is afraid of lowering the temperature. It should be remembered that this culture can die not so much from frost as from incorrect training in the summer-autumn period.
Getting ready to prepare roses for the winter, there are often questions: when should you start to cover the roses for the winter? Is it worth it to trim? what materials to use for shelter?
In the climatic conditions of Russia roses can successfully winter, if in the spring-summer period they were provided with competent care. And in the autumn, when the first frosts came, timely actions were taken.
Prepare a rose for wintering from the summer.
In July, completely stop feeding the culture with nitrogen, due to the fact that its surplus in the stems of the rose adversely affects the ripening of the wood, and even with a slight frost leads to their death.
But, at the same time, it is necessary to start fertilizing the plant with phosphorus and potassium fertilizers. Both potassium and phosphorus have a very beneficial effect on the quality of ripening of shoots, increasing their winter hardiness.
Experienced growers resort to another simple, but effective way of ripening the rose bush. Removing the dried flowers at the end of summer, it is necessary to leave 1-2 ovaries for the formation of the fetus. It is very useful for the ripening of a rose. Giving all the vitality for the ripening of the fruit, the plant prepares itself for the winter sleep. Wood fully ripens, the amount of moisture in it is significantly reduced.
To start to cover the roses only when the cold starts to 5aboutC. Begin by lightly pruning all the inflorescences and ovaries and removing all the leaves, thereby reducing the area for evaporation of moisture from the plant.
To carry out this simple operation is also necessary to ensure that under winter shelter inflorescences and leaves do not become foci of fungal diseases, which can lead to the death of the whole plant. For preventive purposes, the stems of the plant and the soil under it, it does not hurt to treat iron sulfate, usually 5% solution.
Having finished pruning and processing the bush, proceed directly to the shelter. To do this, you will need:
- garden land;
- wooden or wire pins;
- coniferous lapnik;
- dry foliage;
Carrying out activities to cover roses for the winter is carried out in stages. At the onset of frosts to -5aboutFrom the bush hill, or rather pour under the root of the hill from the overripe compost or land height of up to 25 cm.
Further, with the onset of stable frosts to -10aboutWith, pour dry leaves on the mound and cover with spruce or pine lapnikom.
You can not cover roses with dung, hay, straw. They quickly get wet and hold moisture, which leads to the death of the bush.
And, at last, snow is the most top and most reliable layer of shelter. Moreover, the more it is, the better. If the winter turned out to be a little snowy, then it is necessary to sprinkle snow on its own. When the frost is -30 aboutC and the thickness of the snow cover to 60 cm, the temperature near the surface of the earth will be -5 aboutC, which is the optimum temperature for roses in the winter.
For other types of roses, for example, climbing, the technology of shelter differs slightly from the previous one by removing the stems from the supports, they are pinned to the ground, and then hide in the same order as above.
Ground-cover, miniature and polyanthus roses are hidden with the help of boxes, which are covered with lapnik, and then sprinkled with snow.
