Hybrid Tea Rose
Hybrid tea roses are the most famous group of large-flowered garden roses. This is a real aristocrat among roses. The name "tea hybrid" appeared because these flowers came from old tea roses. Tea roses had the aroma of freshly picked tea and beautifully shaped flowers. However, they were not resistant to weather conditions and not sufficiently resistant to disease. After many years of selection, it was possible to develop tea-hybrid varieties, which for these indicators differ significantly from their predecessors for the better. In this article we will talk about them.

Features varieties of tea-hybrid rose group
The group of hybrid tea roses is considered the most popular of all garden roses. It has varieties with a huge number of variations in color, aroma and flower shape. Plants have large flowers and form a bush of small or medium size. If desired, it is easy enough to give them a standard shape. They are ideal for small gardens.
The first variety of this group (“La France”) was obtained in 1867 by the French breeder Guyot from crossing the remodeling rose “Madame Victor Verdier” with the tea rose “Madame Bravi”.
Roses of this group surpassed all forms and varieties known to them in their qualities. They combined the best properties of the original forms. From the teahouses, they inherited the beautiful shape of the flower, a delicate aroma and the ability to bloom almost continuously and plentifully, and from the remodelers, the hardness of the wood and relative winter hardiness.
Hybrid tea roses are distinguished by their elegant composition of flowers and the exceptional richness of their color. They are white, yellow, pink, purple, orange, red, with many transitional tones, as well as two-tone or change color as they bloom.
Varieties of tea-hybrid roses vary in many ways: the height of the bushes is from 50 to 90 cm, the shape is from sprawling to narrow pyramidal. The leaves of some varieties are tender, while others are thick, leathery, matte or shiny. The flowers are double and have from 20 to 128 petals with a diameter of 8-15 cm. On the peduncle often there are 5-7 flowers, and its length varies from 20 to 80 cm. The flowers have an aroma.
In central Russia, hybrid tea roses bloom around June 20 and bloom until late autumn. They are less hardy than repairing ones and freeze already at a temperature of –8 ° С or –10 ° С, but if they are covered, they winter well. Nowadays, they occupy a leading position among other varieties of roses and are widely used in ornamental plantings and greenhouse crops to produce cut flowers.

Features of growing hybrid tea roses
Hybrid tea roses bloom from the end of June until the fall very abundantly. Mass flowering lasts from late June to late July, and then after a short rest, a second flowering wave sets in, lasting until late autumn. Thus, tea hybrid roses are characterized by almost continuous flowering.
Roses are planted in the spring so that the grafting site is 2-3 cm below the soil surface. Pruning is carried out in spring, summer and autumn. Spring pruning is the main one. First of all, the formation of a bush depends on it. Spring pruning of roses begins immediately after the final opening of plants after wintering or during spring planting.
The upper part of the shoots is cut regardless of the variety, strong shoots are shortened to 10-15 cm, leaving 2-3 well-formed buds on them, on weak ones - 1-2. When autumn planting, pruning is done in the spring, immediately after removing the shelter.
Hybrid tea roses are not sufficiently resistant to cold, so they require careful shelter for the winter and, if available, winter well.
Diseases and Pests
The more closely you monitor your roses, the sooner you find pests or recognize a disease - this will allow you to deal with it more effectively.
Pathogens are parasitic fungi. Fungi live off the nutrients the plant receives. Their distribution is facilitated by high humidity, excess heat, as well as nitrogen-containing fertilizers. Fungi propagate by spores that are carried through the air, so diseases spread quickly.
The most common diseases of roses are black leaf spot, rust and powdery mildew.
Rust: The peculiarity of this disease is that the spores that cause its fungus, before getting on the rose, need an intermediate plant of another species, for example, juniper. Do not plant roses near juniper.
Downy mildew: occurs if the summer is rainy. Mold appears on the lower surface of the leaf, which turns into brownish or reddish spots. To prevent the spread of the disease, roses should be planted in a well-ventilated place, and the affected leaves should be destroyed.
Soot coating: the fungus causing it settles on the sweet secretions that aphids leave. Fungal colonies cover the leaf with a sticky black coating. To combat aphids, roses are sprayed with a soap-alcohol solution.
Gray rot: Affects buds, flowers, leaves, and shoots. After some time, a light gray coating forms on them, as well as brown decaying areas, which lead to the death of the affected parts of the plant. The diseased plant is sprayed with horsetail decoction, the affected parts are cut and destroyed.
Viral diseases: Most viruses enter the plant through harmful insects or when pruning with insufficiently clean tools. With the defeat of viral diseases, flowering becomes less abundant, the growth and development of the plant slows down, the leaves brighten. To prevent these diseases, you should thoroughly disinfect the tools, fight against insects that serve as carriers of viruses; affected plants are destroyed.
Pests of roses
Insects: in the form of a larva or caterpillar, they eat leaves, young shoots, roots or buds. Adult insects suck out juice from them and can serve as carriers of viral diseases.
The most common pests are aphids, scale insects, leafworms, rose sawflies, thrips and rose cicadas.
- Leaflet: small butterflies lay their testicles on branches, where they remain throughout the winter. In the spring of them brown caterpillars appear, up to 15 mm long. They eat leaves and buds, and then entangle the leaves with cobwebs and pupate inside the cocoon. Web and twisted leaves are removed and destroyed. With severe damage, insecticides are used.
- Moth caterpillars: green caterpillars eat leaves, buds and young shoots. Affected areas are cut and destroyed.
- Cut nuts: they lay their testicles primarily on the shoots of wild roses. In this case, greenish-reddish, spherical growths are formed, from which whitish larvae then emerge. Affected shoots gradually die off. If growths are found, shoots should be cut and destroyed.
- Spider mites: These animals are not insects, but are tiny arthropods. Especially dangerous is the red spider mite. He sucks the juice from the plant, so that it turns yellow and dies. It does the most harm in a hot, dry summer.
- Pests causing root damage - nematodes - colorless transparent worms 0.5-2 mm long, parasitize on the roots of plants. Cause plant growth disturbances and the formation of thickenings on the roots. The affected plant is removed, in its place for several years planted, for example, calendula, which contributes to the disappearance of nematodes.
