Rosa is an evergreen hardy shrub that, in a mild and warm climate, needs a short enough rest to bloom again soon. In the central and northern regions of our country, not only shelter is needed, but also the proper preparation of the plant for wintering.
How to prepare roses for winter
Varieties of modern breeding are not able to independently enter the dormant period before the onset of cold weather.
Often, rose bushes do not drop leaves for the winter and continue to produce buds. Minus temperatures interrupt the vegetation, but with the onset of the thaw, the plant starts growing again. Therefore, the construction of shelters is far from all that is necessary for the successful wintering of the Queen of the Garden.
How to prepare roses for winter should be taken care of in the middle of summer.
- From the third decade of July, fertilizing with nitrogen fertilizers completely ceases.
- In the first decade of August, the first strengthening root dressing is carried out. Composition: potassium sulfate, double superphosphate (1 tbsp each) and boric acid (1/4 tsp) are diluted in 10 liters of water. The solution is enough to fertilize the area of the rosary in 4 m 2 .
- The second reinforcing top dressing is foliar. In late August, it is necessary to treat the roses on a sheet of potassium sulfate (1 tablespoon per 10 liters of water).
- In September, granular autumn fertilizer with a high phosphorus content is introduced into the ground. It contributes to the rapid ripening of shoots and the strengthening of roots.
In addition, from the beginning of September, watering, digging and loosening of the earth, the formation of a bush, cut flowers are stopped.
How to prepare roses for winter that have not fallen leaves? With the establishment of cold weather, approximately in late October - early November, they must be cut off along with the petioles. During wintering, leafy residues begin to decompose, which can provoke rotting of the buds and shoots.
With the onset of the first frosts, the branches are cut to 20-30 cm. Unripe shoots are removed completely. Before shelter it is necessary to carry out preventive treatment against fungal diseases with Bordeaux liquid or copper sulphate.
Cooking winter apartments
Before preparing roses for winter, you need to remember two main rules:
- Do not hurry! Roses can easily tolerate short-term temperature drops of up to -8 ° C. Shelters that are too covered can disappear too early.
- All preparations should be carried out in dry weather.
As for the material: never use straw, hay, sawdust of deciduous trees, moss, manure.
Shelter roses for the winter, depends on each particular species. Winter-hardy park plants are enough to spud with peat or dry earth to a height of 20 cm.
At the standard roses under the crown lay the spruce branches. Spud up to a height of 30 cm. With dry peat, spruce branches are placed on top or dry leaves are poured. Above single plants, you can build a frame and close it with a film.
The best wintering spot for climbing species is an air-dry shelter. How to prepare roses for the winter in this case? At a positive temperature, the shoots bend to the ground and are fixed with iron hooks. Above them are exposed wooden shields in the form of a gable roof. A film is laid on top, the ends remain open. With steady cooling, they close and also become covered.
