Rosa is one of the most beautiful flowers growing in the gardens of the temperate and subtropical zones of the northern hemisphere. Many gardeners consider the hybrid to be the queen of flowers. A Osiana rose in this case can be considered the queen among roses.
Rosa Osiana: history, description and description
Rose Osiana - the fruit of the work of German growers from the company Rosen Tantau. This variety belongs to the hybrid tea class, which was developed by crossing two other widespread classes: tea rose and remontant.
Rosa Osiana
For your information! As a result, a variation appeared that combines frost resistance and the beauty of the tea rose bud and the continuous flowering of remontans. In addition, tea-hybrid roses have another significant advantage - repeated flowering on the shoots of the current year.
The color of the Oceana rose buds is pastel and can range from ivory to salmon. The flowers are densely doubled in the shape of a glass with a diameter of 10-12 cm, located one on each shoot from 1 to 1.5 m long. This hybrid, like tea rose, is characterized by a pleasant pronounced aroma characteristic only of this variety.
Large dense foliage has medium resistance to adverse conditions. Frost resistance of this variety and resistance to the most common diseases (black spotting, powdery mildew) is lower compared to other rose varieties of this class.
Roses are great for decorating the house area. Rosa Osiana is not suitable for vertical landscaping of the site in the form of arches, waterfalls.
Important! This bush rose is best used to decorate the landscape in the form of flower beds, track design or high hedges.
Osiana rose can be combined in landscape design with other types of flowers and ornamental plants. It all depends on the imagination, taste and professionalism of the designer.

Rose Oseana: cultivation, proper planting in open ground
Proper planting of any plant is the key to its long life and flowering. When deciding to breed hybrid tea roses, you need to be prepared for the fact that they are very whimsical, and they will have to be constantly and carefully looked after.
The best time for planting Osian rose seedlings is the very beginning of May, when the soil warms up to 10 ° C. When choosing a landing site, several mutually exclusive factors should be considered. Roses love the warmth of the sun, and intense sunlight can cause burns to the petals or the stem. Therefore, for planting, you should choose a place where there will be enough sunlight in the morning and evening hours, and in the daytime the bushes will be in the shade.
Planting seedlings
This variety also needs regular ventilation, but the flowers should be protected from the cold northerly winds. Therefore, lowlands are not suitable, it is better to choose a flat, often blown by the winds, sheltered from the north side by the wall of the building.
The most suitable soil for the Osiana rose is black earth. It is possible to plant on loamy soils enriched with organic fertilizers.
Note! Wet or over-moistened soils are not suitable for roses of this variety, therefore the groundwater level at the planting sites should be at least a meter. It is also important to consider the acidity of the soil, which for this flower should be in the range of 6-6.5 pH. Peat or dung can be used to increase acidity, and ash or liming can be used to lower acidity.
Before planting, seedlings with exposed roots should be held for a couple of hours in a bucket of water so that they are saturated with moisture.
Landing procedure (sequence of steps):
- Dig the soil thoroughly and add organic fertilizers (compost or manure) depending on the type, taking into account acidity.
- Dig a hole and put on its bottom a drainage layer of fine gravel. The layer thickness should be at least 10 cm. The width and depth of the hole is selected so that the roots of the seedling are placed in it freely, without bends and kinks. If you plan to plant several seedlings, the holes must be dug at a minimum distance of 70 cm from each other.
- Get the seedling from a bucket of water in which it was before planting, straighten its roots and shorten them by a couple of centimeters.
- Lower the seedling into the hole so that the vaccination site is 5-10 cm below the ground.
- Fill the hole with chernozem or fertilized soil and carefully ram.
Important! After planting, the seedling must be abundantly watered. If the earth around the seedling has sagged, it should be poured, making a mound to protect the flower buds from weather changes.
What care does Osiana hybrid tea rose require?
As already mentioned, the Oceana rose is a rather whimsical plant. It is very hygrophilous, but waterlogging is contraindicated. In non-arid periods, it is enough to water the flowers once a week in the morning or evening hours. In hot or dry weather, rose bushes should be watered daily.
Watering roses
The soil around the plant should be regularly loosened, weeds removed and fertilized soil, which will contribute to its abundant and lush flowering.
For your information! In spring, nitrogen must be added to the soil, and in summer phosphate and potassium.
In the first year of life, a young rose bush should not be allowed to bloom. Before the beginning of August, buds must be removed from it. And starting from August, you can leave 1-2 flowers on the plant.
Pruning of the Hosian rose should begin in the spring, as soon as the buds begin to swell at the base of the bushes. Spring pruning is the most important for the plant, as it gives the plant a direction of development.
Note! Before pruning, live branches with swollen buds and dead ones should be identified and taken into account on which shoots of the bush flowers are formed (on old or young shoots).
Having determined the purpose of pruning (lush and plentiful flowering or shaping the plant), you should proceed to the procedure itself. Strong pruning at a level of 2-4 buds from the base of the shoots is carried out to rejuvenate the bush, moderate pruning at a level of 5-7 buds is used to stimulate early flowering.
In summer, the so-called weak pruning is performed, in which the faded buds are removed, thereby ensuring repeated flowering.
In autumn, the plant is prepared for wintering - overgrown bushes are cut, branches affected by the disease are removed.
With the preparation of the bushes for wintering, there is no need to rush, as this variety of roses can easily tolerate light frosts. But with the onset of steady low temperatures, plants should be covered. For these purposes, spruce spruce branches are most suitable. On top of it, you need to put a heater and cover it with plastic wrap.
Important! In early spring, it is necessary to start airing the bushes by lifting the film floors, and with the onset of heat it must be completely removed so that the buds do not grow early.
Flowering roses
Flowering of this variety begins in June and lasts until late autumn. The first wave lasts from late June to late July. Then follows a short period of rest, and the second wave begins, which ends in the fall.
For your information! During the period of active flowering, so that the flowers are large and beautiful, the plant especially needs watering. Rosa loves pure water without salt impurities, so it is better to use rainwater for irrigation.
It should be watered with a thin stream so as not to injure the roots of the bush, while avoiding the spray on the leaves and buds, as this contributes to the appearance of fungal diseases.
In the first year of the life of the rose bush, it is not necessary to fertilize the soil, since all the necessary things were introduced during planting. In the future, top dressing should be applied after spring pruning (first mineral fertilizers, then organic). Immediately after fertilizing, the soil under the plant should be loosened and watered abundantly.
June flowering
If after the first year the rose has not bloomed, you should find out the cause and eliminate it.
- The lack of sunlight is the wrong choice of planting location.
- Incorrect pruning - in spring, the shoots were pruned too short.
- Improper care - insufficient feeding, lack of moisture, lack of pest control.
- Root growth, indicating that when planting, the vaccination site was not deep enough.
- Aging - after three years, roses should be rejuvenated.
Flower propagation
The pink bush should be propagated by cuttings cut from half-lignified shoots. This procedure is simple and does not require much experience. A suitable shoot is selected and cut into cuttings (with at least one kidney and a leaf) up to 10 cm long. After drying for an hour, the cuttings should be planted in a nutrient substrate, providing it with sufficient moisture by means of a plastic film.
Cuttings for propagation
Diseases, pests and ways to combat them
The most common rose diseases are:
- powdery mildew;
- black spotting;

All of them are manifested in high humidity, affect young shoots, leaves, buds. To get rid of infection, you should burn the affected leaves and shoots and spray the plant with a copper-soap emulsion.
The most dangerous pests for rose bushes are:
- spider mite;
- green rose aphids;
- rose leaflet;
- rose shield.
To combat them, it is necessary to remove pests from the plant and burn them, and the bush itself should be treated with insecticides or bacterial preparations.
Rosa Osiana, with proper care and the choice of a landing site, can bloom for many years. This variety will bring joy to the grower and give beauty to the site.
