Clematis Rouge Cardinal: variety description and characteristics, pruning group, planting and care

Clematis grandiflorum Rouge Cardinal is a climbing vine with large, velvety, rich red flowers. This perennial blooms in the second half of summer. Clematis Rouge Cardinal is grown from a purchased seedling; a large-flowered shrub cannot be obtained from seeds. After flowering, before the onset of cold weather, all shoots are cut to the ground. The next spring, new stems grow, buds appear on them again.

Description and features

Clematis Rouge Cardinal (Red Cardinal) is a climbing herbaceous plant of the Ranunculaceae family.Belongs to the Jacqueman group. It is a late flowering large-flowered shrub. A distinctive feature of this crop is its rapid growth - shoots stretch 6-10 centimeters in length per day.

The tendrils of the creeper are very tenacious. Clematis easily climbs onto a support on its own, grabs any ledge, fixes itself and stretches upwards. It is a perennial that overwinters in the soil. True, before frost, the shoots are cut up to 20 centimeters above the soil level.

Each new season, clematis grows up to 1.8-3 meters in length. The root goes deep into the earth by 1 meter. The color of young shoots is light green. The leaves are dark green, small, leathery, pinnately compound, consist of 3-5 leaves. Rouge Cardinal blooms from July to September. Flowers appear on the shoots of the current year. Clematis bloom is interrupted by the first autumn frosts.

Flowers - dark red, with 6 petals, velvety, 10-16 centimeters in diameter. In the center are cream colored filaments with brownish anthers.

History of Rouge Cardinal breeding

Clematis Rouge Cardinal is a hybrid bred by French breeders in 1968. The new plant was obtained by crossing two clematis - Vititsella and Lanuginose. The variety has received many awards at prestigious international exhibitions, was awarded a gold medal at a competition in Holland.

Landing

Hybrid Rouge Cardinal can be grown from a cutting with a rhizome and a twenty-centimeter shoot remaining after pruning with 2-3 vegetative buds or from a seedling planted in a pot. It's easier to buy a young clematis in a container in the spring and transfer it along with a clod of earth to a flower bed.

Seat Requirements

Clematis Rouge Cardinal is a light-loving crop, but can grow in light partial shade. It is better to plant a seedling in flower beds well lit by the sun, in places protected from wind and drafts.The shrub does not tolerate stagnant water, the soil on which it is planted must have good drainage.

Selection and soil preparation

The land where the landing is planned may be neutral or slightly acidic. Clematis can be planted on loam or sandy soil. Too acidic soil must be limed. Heavy, clayey, poor soil can be diluted with peat, sand, rotted humus. The soil is prepared a few days before planting clematis. They dig a hole, choose the earth from there and add additives.

In addition to organic matter, peat or sand, be sure to add superphosphate (100 grams), 200 grams of wood ash, 100 grams of bone meal. All components are mixed and poured back into the hole, leaving a small hole for planting the plant itself.

Disembarkation dates

Clematis seedling grown in a container is planted in a flower bed in May, when the soil warms up to 10 degrees Celsius, and the weather is warm and the threat of night frosts has passed.A rhizome with a 20 cm long shoot with 2-3 buds remaining after pruning can be planted at the end of April. In the southern regions, the delenka is planted in a flower bed in the fall (from late September to early November), 1 month before the onset of frost.

Plant pattern

2-4 weeks before planting Clematis Rouge Cardinal, a hole is prepared. It takes some time for the ground to settle a little. The pit is dug 65 centimeters deep and 55 centimeters wide. The earth is enriched with humus, diluted with peat or sand. At the bottom of the hole, a ten-centimeter layer of pebbles is poured as drainage. Then fertile soil is laid.

Before planting, you need to install a support for climbing vines. It will support the clematis in case of strong winds. It is undesirable to plant the plant close to the wall of the house, it is better - at a distance of 30-50 centimeters. Water flowing from the roof should not fall on the bushes. To a neighboring plant, 1-1.5 meters of free space are left.

A seedling from a pot, together with a clod of earth, is carefully transferred to a previously prepared hole. The stem is covered with earth to the first internode. After planting under a bush, a bucket of water is poured. If the soil near the shrub sags over time, you need to add a little earth. When a delenka is planted, the roots, along with the shoot, are deeply immersed in the soil. The root neck should be 5-8 centimeters below the soil surface. Only the top of the seedling should remain at the top.

Rules of care

Clematis Rouge Cardinal is an unpretentious culture. However, in case of non-compliance with the rules of agricultural technology, it may bloom poorly, wither or drop buds. In the spring, at the beginning of growth, the vines are directed in the right direction, forced to curl around the support, tied up. If this is not done, the growing branches will intertwine or stretch in the wrong direction.

Irrigation

After planting, clematis should be watered regularly. Once a week, a bucket of water should be poured under the bush. An adult plant is watered only in dry weather. During watering, it is advisable not to allow a jet of water to enter the center of the bush.

Feeding

Clematis Rouge Cardinal responds excellently to the application of organics and all kinds of mineral fertilizers. The shrub is fed 3-5 times per season. If clematis grows on poor soil, in the spring you can pour compost or rotted humus under the bush. Organic and mineral top dressings are not applied at the same time, they observe an interval of 10-14 days.

In the summer, once a month, the foliage is sprayed with a solution of urea (1 teaspoon per 10 liters of settled water). Before flowering, the bushes can be irrigated with a solution of boric acid (2 grams per 10 liters of liquid) and poured with a weak solution of potassium permanganate. In summer, clematis is fertilized with superphosphate and potassium sulfate (35 grams per 10 liters of water).

Weeding and loosening

After watering, the ground near the shrub needs to be loosened a little, remove the weeds. In hot weather, to protect the roots from overheating, it is recommended to mulch the soil near clematis with peat or sawdust.

Crop groups

Clematis needs constant care. Throughout the summer - remove dried or broken shoots. With the help of pruning, the height of the shrub is adjusted. If you pinch the main stem, you can stop its growth and stimulate the development of side shoots. Of great importance is the correct autumn pruning of the shrub. All varieties of clematis are divided into 3 groups according to the method of autumn pruning. Rouge Cardinal belongs to the third group.

First

Clematis, blooming on the shoots of the past year, are not pruned before the onset of winter. Such plants are only slightly shortened in autumn. After all, branches grown in the new season rarely form buds. The first group includes clematis large-leaved, alpine, mountain, Siberian. For the winter, frost-resistant varieties are left on a support without shelter, and hybrids are bent to the ground and insulated.

Second

Clematis, which bloom on the shoots of the past year and on new branches, belong to the second pruning group. In summer, old shoots are removed after flowering is completed, and in late autumn, young branches are shortened by a third. Before wintering, the plant is bent to the ground and insulated. The second group includes clematis Patens, Florida, Lanuginoza.

Third

This pruning method is suitable for Clematis Rouge Cardinal. In autumn, the shoots are completely cut off. Leave only small stems 20 centimeters long, with a pair of buds. The next spring, new shoots grow, in the middle of summer flowers bloom on them. Clematis, which are completely cut off before winter, are more tenacious. The shoots of such plants do not need to be stored until the next season or insulated. The third group includes clematis Jacqueman, Intergriffolia, Vititsella.

Shelter for the winter

The roots left in the ground and low cut stems are covered before winter.The temperature must be below zero outside. The base of the bush is sprinkled with peat with humus, sawdust, dry foliage. In winter, more snow is poured to the place where clematis hibernates. They take shelter in the spring, after the snow melts.

Diseases and major pests

Clematis Rouge Cardinal can get sick with anthracnose, rot, fusarium, powdery mildew, rust. Improper care, lack of nutrients in the soil, rainy and cool weather can provoke fungal and bacterial diseases. It is advisable to carry out preventive treatment of plants with chemicals in the spring.

After the snow melts, before the shoots appear, the ground can be watered with milk of lime (210 grams of lime per 10 liters of water).

Fungicides are used to protect against fungal diseases: Maxim, Skor, Horus, Quadris, Radomil. In hot weather, the shrub is attacked by insect pests. Preventive treatment with insecticides (Aktellik, Aktara) saves them from them.

Fusariosis

Fusarial wilt is caused by fungi living in the soil. They affect the roots, penetrate into the conducting system of blood vessels, growing, clog it with mycelium. A diseased plant quickly loses its freshness, fades, dries up. To prevent diseases in the spring, the earth is watered with a solution of copper or iron sulphate, in the summer a solution of Trichodermin is poured under a bush.

Wilt

Fungal infection that affects the roots and shoots of clematis. The pathogen is in the soil, penetrating through the roots into the stem, clogs the internal vessels, disrupts their patency. Nutrients do not come up, the plant begins to wither and dry out. The plant affected by the fungus cannot be saved.

In the spring, preventive measures are taken to reduce the likelihood of a fungal disease. The soil is watered with a solution of potassium permanganate, Fundazol, Trichodermin, copper sulphate or Bordeaux liquid.

Spider mite

A tiny reddish insect spinning a web from the back of a leaf. Activates on hot days. It feeds on the sap of the plant, causing the leaves to turn yellow and the buds to dry out. Insecticides save from spider mites: Actellik, Karbofos, Inta-Vir.

Fly

A small two-winged insect whose larvae feed on clematis leaves, creating an extensive system of passages in them. The integrity of the leaf plates is broken, causing the leaves to wither and fall off. You can save clematis from flies with a trap (adhesive tape). Leaves are sprayed with insecticides (Aktara, Konfidor, Mospilan) as a preventive measure.

Thrips

This is a small insect with an elongated dark brown body. Larvae and adults feed on plant sap. Insects live in the soil. They climb clematis in search of food.The vital activity of insects is evidenced by spots on the leaves, yellowing of the foliage. Insecticides save from thrips: Actellik, Fufanon, Aktara, Marathon, Ortin.

Nematodes

Microscopic worms living in the soil. Insects damage the root system of clematis. Brown swellings appear on the roots, causing rotting, because of which the bush looks drooping, stops growing, fades. Clematis leaves can be attacked by another type of these insects - leaf nematodes. The vital activity of pests leads to the drying and death of foliage. Drugs save from the nematode: BI-58, Rogor, Dimethoat.

Reproduction

Clematis Rouge Cardinal is propagated mainly by vegetative means. It is not possible to grow large-flowered varieties from seeds, since new plants do not retain the hereditary characteristics of the mother crop.

Dividing the bush

This method is used to rejuvenate the bush. With age, Clematis Rouge Cardinal begins to bloom poorly, loses its decorative effect. The bush is divided in the spring, until the buds start, or in the fall - after flowering. For division, a shrub aged 5-8 years is chosen. They cut off the entire ground part, leaving only short shoots with vegetative buds at the base.

The bush is dug up, the roots are separated from the ground, with a knife they are divided into several divisions. On each part, an escape with buds and enough roots should remain. An independent plant grows from each division.

Layers

In summer, the overgrown lower side stem is bent to the surface of the soil and sprinkled with earth. The top is brought out. In the second year, the branch will grow roots, it can be cut off from the mother plant, and the young shoot with roots that has appeared needs to be transplanted to a new place.

Cutting

In summer, slightly lignified cuttings 10-12 centimeters long are cut from the plant, the leaves are torn off and placed in water with Kornevin or Heteroauxin. Then the branches are stuck into a wet sandy-peat substrate and covered with a plastic bottle on top. When the cuttings take root, they are transplanted to a permanent place.

Application in landscape design

Clematis Rouge Cardinal is grown for vertical gardening of a garden plot, walls of houses, fences, balconies, terraces, pergolas, arbors. A tenacious vine can grab onto any support, arch, climb up a tree. The plant can be grown in containers, on balconies and loggias. With proper care, clematis can grow in one place for 10-20 years.

Reviews

Valentina, 47 years old.

“I have been growing Clematis Rouge Cardinal for about 9 years. During the summer, the vine stretches to a height of up to 2.45 meters, blooms profusely. In autumn, I cut the stems, leave shoots 20 centimeters high, sprinkle them with earth. The flower overwinters well, and in the spring, to stimulate growth, I feed it with nitrogen. ”
