History of occurrence

Rosa Cordes is a hybrid plant, which was obtained as a result of crossing two varieties - Rugoz and Vikhuroyan. The German family company called Wilhelm Cordes and Sons was engaged in breeding. This event took place at the beginning of the 20th century, and the company itself was founded in 1887.

This variety of roses has become popular and eventually developed into a separate species. For this species, the descendants of Wilhelm Cordes continue to engage in flower breeding, and recently the Nikitsky Botanical Garden, which is located in Crimea, has received the right to plant and receive new varieties of Cordes roses.

• Cordes is also popular due to its strong immunity to many types of diseases and pests.

Is it possible to grow in open ground?

The answer is unequivocal - not only possible, but necessary. Firstly, the rose will perfectly tolerate all climatic differences. And secondly, for home cultivation, this variety has too large dimensions.

But this flower will fit perfectly into the landscape design of any garden plot.

Bloom

When and how?

This variety dissolves a huge number of buds. This happens from the very beginning of summer, and sometimes from the end of spring, and continues until late autumn.

Care

Usually, before flowering, in early spring, one of two prunings is carried out. Cut about 10-15 centimeters. It will not be superfluous to feed the plant in March, for this they use nutrient complexes designed specifically for roses.

After the last rose petals have fallen, it must be cut again, but this time more radically. Only 2–3 living kidneys are left for the winter, the remaining length is removed.

What to do if it does not bloom?

Correct errors that result in a lack of flowering. There may be several.

• Lack of extra power. In addition to the fact that the soil must be loose and fertile, it must also be saturated with organic matter. Therefore, in spring and autumn, the rose must be fertilized, otherwise flowering will not wait.
• Plant age. If the flower is already quite old, it needs to be rejuvenated - for this, old roses are removed, and new ones that can be obtained from cuttings of adult plants are planted in their place.
• Not enough light. In full shadow, the rose will only grow green mass, and also reach up to the sun.
• Incorrect pruning. It is necessary to remove old and dried shoots every spring and autumn.
• Faded buds. They also take nutrients, so they are immediately cut off.

Use in landscape design

Rattled roses are used by designers quite often. Indeed, thanks to them, you can create any floral arrangement.

Remember to leave at least a meter around for every Cordes rose.

This variety of flowers is perfect for creating live arches., using them you can braid any gazebo, hedge. Coniferous shrubs will be planted near roses - they will slightly shade the plants, but in no case do not arrange a complete shadow.

Step-by-step landing instructions

Seat selection

1. Experienced flower growers recommend planting Cordes roses on the hillocks.
2. There should be a lot of light. But it is advisable to arrange the plant in such a way that during the hours of intense heat the plant is in partial shade. The health of flowers, their resistance to pests and diseases, as well as the abundance of flowering, directly depends on the amount of light.
3. We strongly recommend that you do not plant roses under the trees. They will take away from the flowers not only the whole world, but also nutrients.

What should be the soil?

The soil should not be too wet.. In such a substrate, there is always not enough oxygen, which leads to diseases or the complete death of the plant.

Soil acidity should be neutral. The most optimal indicators of acidity are 6-7.

The substrate must be constantly loosened and replenished once a month.

Seeds

Seeds can be purchased ready-made at the store.. And you can cook with your roses.

1. For this, seeds are harvested in late July and early August. Only elastic seeds are used.
2. After collection, the material is placed in a container with hydrogen peroxide (3%) for 30 minutes. Those seeds that have surfaced are thrown away, as they are hollow. At this point, disinfection also occurs.
3. The remaining seeds are treated with a growth stimulant.
4. After the shell of the seed, you need to soften for more successful germination. To do this, the seeds are mixed with river sand, and then wrapped in a cloth that is saturated with peroxide. All this is placed in a plastic bag and put in the refrigerator.
5. Look through the seeds periodically to remove those that are moldy.
6. After germination of the boxes they are ready for planting.

Temperature

These flowers easily tolerate frosts. The optimum temperature in the spring and summer is from +15 to +25 degrees. At elevated degrees, it is better to moisten the plant more often. The varieties of roses of Cordes are quite winter-hardy: they can withstand temperatures down to -40 degrees. However, experienced gardeners recommend not taking risks and still cover the flowers before the onset of cold weather.

Watering

Humidification of the soil is carried out twice a week. After each watering, loosen the soil.

Top dressing

Fertilize the plant twice a month before flowering. As soon as the first flowers have blossomed, top dressing is reduced to once a month.

Pruning

This procedure is carried out in autumn and spring. In the spring, only 10-15 centimeters of shoots are cut, but in the fall they cut to the maximum, leaving only 2-3 live buds.

Transfer

Better to do it in the evening. Dig up roses with a large lump of earth and immediately place in a new place. After this, the flower should be abundantly moistened and covered for several days from the sultry sun.

Preparation for winter

Everything is very simple here.

1. Just cut the shoots and hide the rest. To do this, you can use a regular bag or a dense plastic film.
2. Sprinkle the roots with dry foliage and additional soil.

How to propagate?

The most suitable way is cuttings. To do this, in the autumn after trimming, many cuttings remain.

1. You need to choose those on which there will be at least 6 live kidneys.
2. Then these cuttings are placed in the ground so that three buds are in the ground, and three more in the open.
3. For the winter, cuttings are covered with jars or cropped bottles.
4. In the spring, the processes begin to harden. To do this, with the advent of positive temperatures, roses open every day for a short period of time. Start with five minutes. and every day time is increasing.
5. Somewhere in a month, roses can be fully opened.
