Climbing roses are one of the most attractive plant species. But to grow them up is quite difficult. It is necessary to pay attention to agricultural technology and protection from diseases and pests.
A plant like the climbing rose Pierre de Ronsard looks intriguing. Seeing her for the first time, it is difficult to drive away the idea that this is some kind of old variety. However, the reality is not so. Such a culture was first introduced in the mid-1980s, and since 1987 it is registered in the French state registry. Pierre de Ronsard is classified as a representative of a large flowering climbers group.
This variety has the following main characteristics:
- shoot growth - from 1.5 to 3.5 m;
- flower diameter - from 0.09 to 0.1 m;
- zone of rose growth - 1.5–2 m;
- the number of flowers per stem - up to 13 pieces;
- delicate, not emotionally annoying aroma;
- moderate resistance to winter conditions, to the defeat of powdery mildew and black spotting;
- optimal landing time is the last days of April and the beginning of May.
Climbing roses of the Pierre de Ronsard variety form highly developed bushes of increased power. Even in the cold regions of Russia, they grow up to 2 m. The variety description indicates that shoots are hard near the ground, but closer to the upper and lower edges, flexibility grows. When they bloom, the stems even bend under load. The geometry of the bud accurately reproduces the appearance of old varieties.
A bud has at least four dozen petals. Importantly, their tonality changes in the process of development. A soft pink hue dominates. A brighter color is characteristic of the center of the flower, and closer to the edge it pales. If clouds gather in the sky, the buds will partially open, but when the sun peeks out, they become almost flawless white.
The flowering period is quite long. However, in the last days of July and in the first ten days of August, it is interrupted. After the resumption of flowering, the appearance is already less attractive - the size of the buds decreases. An attractive feature of Pierre de Ronsard is its relatively high resistance to major flower diseases and harmful insects. The only drawback of culture can be considered the weakness of the smell, sometimes it is completely absent.
Cultivation and Care Conditions
Climbing roses, judging by the experience of use, can develop 15–20 years. Still in France there are bushes planted in the 1980s. Despite the optimal adaptation to the warm Mediterranean climate, even in central Russia, Pierre de Ronsar is very good. Much depends on the quality of preparation of the land. The prerequisites for success are the following:
- open and well-lit terrain;
- flat terrain;
- reliable cover from piercing winds;
- fertile soil with a good structure.
It is important to remember that the root system of climbing roses can grow up to 2 m in depth, so an attempt to grow them in areas with a high level of groundwater will result in failure. Alternatively, you can drain the land or build a high terrace. It is recommended to make landing pits with a minimum depth of 0.5 m. It is required to lay out the area with well-loosened loam with high fertility and a neutral chemical reaction. The main measures for caring for a planted plant are as follows:
- systematic irrigation;
- shelter before the onset of winter;
- fertilizing with mineral and organic fertilizers.
Among these manipulations, the shelter before the arrival of the cold is considered to be deservedly the most difficult thing. In winter, Pierre de Ronsard on a pylon will not survive. It would be more correct to create a decorative building. It is very good if she herself (without entwining shoots) will attract enthusiastic looks.
Attaching the bush to the trellis and removing it should be done very carefully.
Supports set in advance. They should completely exclude contact with lashes and soil. The slightest hit of dampness will result in rotting shoots. The peculiarity of the variety is also the fact that aesthetic advantages are most revealed in a solo format. Therefore, among all the places in the garden or in the garden, in the adjoining territory, for stylistic reasons, sites viewed from everywhere are best suited.
Bushes can be formed exactly in the same configuration as the supports. To fasten lashes of large length, elements such as:
- individual columns;
- garden pyramids;
- standard trellis;
- arched structures.
When the garden is just planned, it is advisable to immediately allocate places for arbours and canopies for Pierre de Ronsard, best of all - from the southeast. With this arrangement, in the hottest hours, the bushes will create a pleasant shadow. Importantly, the climbing plant is not much affected by the harmful effects of heat, it will not provide protection from rainfall, but it will not suffer from them. "Pierre de Ronsard" responds well to the introduction of additional fertilizing. With the beginning of spring, nitrogen compounds are introduced. Just before flowering comes the turn of mineral recharge. When it is already ending, but not yet finally completed, you can add phosphorus and potassium mixtures.
Attention should be paid to the introduction of mulch. The worse the soil on the site, the further it is from the optimal values for a given variety, the more important is mulching. The backfill layer is from 4 to 6 cm. When it decays, the entire resulting mass is mixed with the upper layer of earth. This process needs to be repeated one more time. The choice of mulch is quite diverse, namely:
- manure of various animals;
- dry grass;
- crushed paper;
- garden compost;
To prevent the development of diseases, at the beginning of the growing season and before the cold weather, the climbing rose is carefully treated with a weak solution of Bordeaux fluid.
As for the supports, they should always exclude the shadow from getting onto the bush itself. The use of a piece of bamboo branches or already developed trees as supports is an original step. Cut "Pierre de Ronsard" will have as soon as flowering is completed. This procedure is repeated in the spring.
In the autumn months, obsolete shoots are harvested, and fresh shoots are shortened only by ¼. From March to May (depending on climatic conditions and actual weather), deformed shoots are removed. Of great importance is the cutting of lashes. The correct folding of the bushes depends on it. Roses with partially cut lashes bloom much more intensively. As you can see, the cultivation of "Pierre de Ronsard" does not require special difficulties.
As practice shows, “Pierre de Ronsard” is growing well in regions with any climate. On the shores of the Black Sea, this rose fully reveals its capabilities. The lack of smell can hardly be considered a serious problem, given the other advantages. In the Volga region with a skillful approach, the bushes bloom almost all summer. Garter to the fence (no extra trellis) is enough.
Even those gardeners who have tried 20 or more varieties cannot name a less capricious culture. In the coldest years, frostbite of branches during winter is compensated by rapid growth and development in spring. By the middle of summer, if the weather permits, flowering returns to normal. But in the 4th climate zone, problems can arise.
If they are aggravated by improper agricultural technology or the poor quality of the seedling, sometimes flowering does not occur at all.
