The brightest representative of hybrid tea roses of scarlet color is the Osiria variety. Fragrant bicolor buds are a real pearl of any bouquet and a sophisticated decoration of the garden.
Description of the rose Osiria (Osiria): what kind of variety
Hybrid tea rose Osiria was bred in Germany in 1978 in Reimer Kordes nursery. About the gene pool chosen by the originator for the work, it is reliably known only that the Snowfire variety was used, among others.
The height of an adult well-formed bush is 70-90 cm. The shoots are long, straight, strong, only sometimes slightly curved. The width of the crown is about 80 cm. The bush is formed sprawling, directed upwards, densely leafed. Large dark green matte leaf.
The bud is formed into a densely double goblet shape, and when fully opened, it turns into a bowl. The petal on the front side is velvety red (ripe cherries or strawberries), and on the inside - creamy milk with silver. Flowers are formed at the ends of the shoots, always 1 pc. Corolla diameter 9-12 cm. The first bud opens in early June, the last in October. The aroma is spicy, but light, intensifying in damp weather and in the evenings.
Advantages and disadvantages of the variety
Among the undeniable advantages:
- frost resistance up to −23 ° С;
- long (up to 4 months) flowering;
- powerful straight shoots are great for cutting;
- pleasant and distinct aroma;
- durability: the bush grows for several decades in one place;
- easily propagated by cuttings with all the characteristics preserved.
Disadvantages:
- lack of nutrients can trigger the development of chlorosis;
- in too hot sun the bush can get burns, it is better to plant it where there is light shading for part of the day;
- instability to powdery mildew and rust;
- tough shoots are not suitable for propagation by layering;
- under their own weight, the buds soaked after the rain droop.
Use in landscape design
The bushes have a very decorative look, therefore they are widely used to decorate flower beds, flower beds, gardens.
Growing a flower
In gardens, Osiria appears mainly from nurseries where cuttings with open or closed root systems are sold. Sometimes you can find planting material grafted onto a 2-year-old rosehip. Its winter hardiness indicators are 10-15 ° higher.
In what form is the landing
A cut with a closed root system can be planted immediately after purchase (end of May, all summer). It is only important to prepare the planting hole in the selected location. A seedling with open roots must be soaked in water overnight before planting.
A high-quality cutting has 2-3 lignified shoots with dormant buds, well-developed roots. A healthy root is elastic and light without any signs of decay.
The optimum diameter of the root collar is 8-10 mm. There are no leaves and flowers on the seedlings, the maximum are blossoming buds.
What time is the boarding
Late spring - early summer is the optimal time for planting. The soil should be warmed up to a level above 12 ° C.
Seat selection
You need to plant in a slightly elevated place where rain or melt water never stagnates. If they are planted near the walls, then the optimal distance is from 50 cm. A good place is where the bright sun shines for part of the day (preferably morning), and light partial shade reigns the rest of the time.
How to prepare the soil and flower for planting
The optimum acidity of the soil is pH = 5.0-6.5. It should be loose and fertile. If soil extracted from the pit is used for planting, then up to 1/4 of sand and peat are introduced into it. Useful additives are wood ash, chalk or dolomite flour. Of the fertilizers, 50 g of superphosphate are mixed (50 g per 1 hole). A seedling with closed roots is not prepared in any way, but with open roots, it must be pre-soaked in water.
Landing
Step-by-step instruction:
- A hole is dug 50-60 cm deep.
- 5-10 cm of sand with crushed stone or expanded clay are poured onto the bottom for better drainage.
- The bush is buried by 2-3 cm (but only up to the scion).
- Fall asleep with prepared soil, mulch, water abundantly.
Plant care
All varieties of hybrid tea roses require attention. Osiria is no exception.
Watering rules and humidity
Water the bush when the soil under it has dried out (after 2-3 days). Stagnant water is harmful to the roots.
Top dressing and soil quality
The rose responds well to watering with mullein solution, but only in the first half of summer. Mineral fertilizers are bought and made special for roses with a predominance of phosphorus and potassium. In total, up to 4 dressings are required per season.
Pruning and replanting
In spring and autumn, sanitary pruning is carried out, removing damaged, diseased shoots directed into the bush. Cut out the shoots below the scion. In the spring, shoots are cut, leaving 3-4 buds on them for a harmonious crown formation.
Features of wintering a flower
After the autumn pruning (it is carried out after dropping the foliage), the bush is covered with a cardboard box or bag, a film frame. After the establishment of frost of -7 ° C, dry foliage or needles are poured into the shelter. They remove the shelter as soon as a stable above-zero temperature is established during the day.
Blooming rose
Beautiful flowers are a welcome reward for all efforts. Assyria is a rose that delights them from the very first year after planting.
A period of activity and rest
Flowers are formed only on the shoots of this year. On average, blooming occurs at 2-week intervals, but not synchronously. If there are several bushes nearby, then they can bloom one by one. Flowering lasts from June to October.
Care during and after flowering
Withered flowers should be cut off all summer. It is correct to do this - until the first bud below the bud. If you cut more, you can weaken the bush. In September, wilted buds are not cut, so as not to provoke unnecessary shoot growth.
What to do if it does not bloom
Lack of light, water and nutrients are the main reasons for the lack of buds. Roses bloom even in cold weather, if they have enough phosphorus and potassium. The best strategy is to feed the bush and make sure watering is done on time.
Flower propagation
Cutting is the best breeding method for the Osiria rose. Dividing the bush is only suitable if the seedling was grown from a cuttings, but not grafted onto a rose hip.
The optimal time for cutting cuttings is June, when the bush is already in bloom. Shoots need well-formed, strong and long.
Stages of the cuttings procedure:
- The stalk is cut 10-12 cm long from the end of this year's shoot, removing the bud and leaves from the bottom.Leave 1-2 leaves, shortening them in half.
- Having dipped the lower end into the root, the cutting is buried in a mixture of sand with fertile soil or placed in a container with clean water. It is advisable to cover the top with a cap to maintain optimal humidity.
- The greenhouse is placed in the light and kept at a temperature of 22-25 ° C.
- After 3-4 weeks, roots should form.
- Landing in open ground is carried out in a year or at the end of August.
Diseases, pests and ways to control them
Before the summer season, the rose is treated with copper sulfate or Bordeaux liquid to protect it from powdery mildew and rust. Then they carefully monitor extraneous spots on the foliage, and if sick are found, they are carefully cut and burned.
Rose of Osiria is a real treasure in the garden, because its buds become larger and more fragrant with each subsequent year. For an experienced gardener, it will not cause much trouble, the principles of care are general, as for other hybrid tea varieties.
