Characteristics
Cherry plum of an early hybrid variety Yulskaya Rosa takes root easily and is distinguished by unpretentious care. The main characteristics of cherry plum July Rose allow you to determine the intricacies of agricultural technology.
Drought tolerance, winter hardiness
The cherry plum variety Yulskaya Roza is characterized by a high degree of frost resistance (up to - 36 ⁰С) and winter hardiness in the official region of admission, according to the recommendations of the originator.
Drought resistance - average, the culture requires additional watering during the dry summer. In case of excessive irrigation, the July Rose can be attacked by aphids.
Cherry plum pollinators July Rose
In the State Register of Breeding Achievements, cherry plum variety Yulskaya Roza is positioned as a self-infertile crop.
The originator of the variety, in turn, draws attention to partial self-fertility and, in order to improve the palatability of fruits and increase yields, recommends placing the crop next to pollinating varieties that are characterized by the same flowering period ("Found", "Traveler", " Pramen ").
Flowering period and ripening period
The flowering period of the July Rose falls on the first days of April. Cherry plum inflorescences are expressed by two flowers, as well as a large number of flowers on one shoot. The calyx has the shape of a bell with sepals pressed against the petals.
Productivity and fruiting
The cherry plum variety Yulskaya Roza enters the phase of active fruiting at 3-4 years of life. By the age of 8, the tree gives record harvests (up to 10 kg in one season).
Fruiting of the July Rose begins in June and lasts for several weeks. Ripening of fruits is uneven, but the yield is regular and stable. Since the fruits are unstable on the stalks, harvest should be done immediately, as the cherry plum ripens. Ripe fruits become red-burgundy, sweet, juicy.
Scope of the fruit
According to experts, the taste characteristics of the Yulskaya Roza cherry plum variety were estimated at 4.4 points. Ripe fruits are distinguished by the optimal sugar-acid index - 3.0, they contain the maximum amount of natural components:
- up to 7.8% sugar;
- up to 2.3% acids;
- up to 10.9% dry matter;
- up to 6.67% vitamin C.
Cherry plum of this variety is a versatile product that is used with great success fresh, for processing and conservation.
Transportability and keeping quality of fruits is average. Cherry plum transportation is possible provided it is stored correctly. For the first 7-10 days, the fruits removed from the tree are stored open in a wooden box. In a dark, cool room, they can lie for up to 1 month.
Disease and pest resistance
The culture has a stable immunity to the main causative agents of diseases. An early hybrid variety of cherry plum, Kometa Rannyaya, is practically not exposed to pests.
Advantages and disadvantages
An early ripe cherry plum hybrid July Rose compares favorably with other fruit trees in terms of fruit ripening. The vitamin composition of the pulp is of undoubted benefit for the human body.
Pros:
- early maturity;
- high productivity;
- original plum taste;
- large fruit size;
- persistent immunity to diseases and pests;
- endurance in various climatic conditions.
Minuses:
- partial self-fertility;
- uneven aging;
- average level of drought resistance.
Landing features
Experienced gardeners put emphasis on the autumn planting of cherry plum seedlings in open ground in the regions of admission. Since the culture is unpretentious and undemanding, there are no special difficulties and requirements of agricultural technology.
Recommended timing
Cherry plum seedlings July Rose can be moved into open ground in spring or autumn (from April to October).
In the spring, trees are transplanted before the beginning of the period of active sap flow, provided that they are at rest. When buying seedlings with a closed root system, moving to open ground is carried out at any time from April to October.
Seedlings with an open root system can most often be purchased from specialized nurseries in the fall. Autumn planting is most preferred for plants.
Choosing the right place
The most successful place for placing cherry plum trees can be called the southwestern or southern slopes. The ideal option would be a protective barrier from the wind and bad weather from trees or buildings from the north or north-east side. In addition, the following factors are important for the plant:
- lack of shading;
- the presence of loose, well-drained, neutral soil;
- lack of waterlogging and contact with groundwater.
What crops can and cannot be planted next to cherry plum
Cherry plum is compatible with crops such as apple, gooseberry, raspberry, black currant, maple, elderberry. Maple stimulates the fruiting of cherry plum, elderberry blocks the attacks of aphids.
Uncomfortable cherry plum with birch and various fruit trees, except for the apple tree.
Selection and preparation of planting material
Cherry plum sapling July Rose must have a healthy appearance:
- well-developed fibrous roots;
- the absence of cones, growths, dry and rotten branches on the roots;
- healthy, smooth bark without cracks or damage on the trunk and branches.
2-year-old seedlings should be purchased, since older crops are more difficult to adapt, harder to take root, and are characterized by later fruiting.
Before planting in open ground, the root system should be placed in water for several hours. To stimulate growth, growth stimulants are added to the water: "Epin", "Heteroauxin", "Kornevin".
Landing algorithm
The planting hole is formed in such a way that the root system can be placed. The optimal hole size for a 2-year-old cherry plum seedling is 40 cm x 100 cm.Drainage from expanded clay, crushed stone or broken brick, up to 15 cm thick, is placed at the bottom of the planting pit.The nutrient mixture for filling the planting hole should consist of equal parts:
- black soil;
- sand;
- bottom peat;
- humus;
- 400-500 g superphosphate;
- 3 liters of wood ash.
A planting pit with a nutrient mixture must be prepared in advance, covered with roofing material or slate to prevent the washing out of nutrients during the rainy season. When favorable conditions occur, the seedlings are transferred to open ground. Part of the land is taken out of the landing hole and the algorithm is followed:
- a mound is formed in the center of the hole;
- in a small distance from the center (at a distance of 10-15 cm), a peg up to 1.2 m high is driven in;
- the seedling is placed on a mound in such a way that the roots are freely distributed along the slopes of the mound, and the neck of the root system is located at the top of the mound;
- the seedling is sprinkled with earth, while carefully tamped, tied to a wooden peg;
- a tree-trunk circle is formed around the tree;
- a young tree is watered (10 liters of water per seedling).
Follow-up care of the culture
Regular care of the hybrid cherry plum July Rose consists of the following steps:
- watering 1 time in 3 weeks with deep moistening of the soil 25 cm deep at the rate of 3-4 buckets of water per adult tree;
- removal, weeding of weeds for aeration;
- loosening to ventilate the root system;
- caring for the near-trunk circle (mulching during the first 2-3 years of life with a 10-cm layer of humus or peat with periodic changes 3-4 times per season);
- sanitary pruning of the branches of the July Rose, formation of the crown 2 times during the growing season (in spring, mainly in March before bud break, - removal of lateral branches by 20 cm, rejuvenating pruning at the 8th year of life);
- feeding with nitrogen-containing mineral fertilizers in the spring for 3-4 years of life;
- inspection for signs of diseases and pests;
- timely harvest;
- preparation for winter - whitewashing of trunks to prevent the appearance of burns in the spring, covering the trunk of trees with a casing made of sheet iron with sacking wrapping (relevant for the regions of the Middle Strip and the Trans-Urals).
Diseases and pests, methods of control and prevention
The hybrid variety of cherry plum Kometa Rannyaya is resistant to pathogens and insect infestations. In some cases, cherry plum July Rose can become infected with the following ailments:
- Trees become infected with coccomycosis from mid-July, brown or red spots appear on the foliage.
- Marsupial disease provokes a decrease in yields by more than 2 times. Fungus affects fruits that are characterized by an elongated shape, green in color with a white bloom.
- Fungal moniliosis is a monilial burn or fruit rot. In the spring, burn ulcers form on foliage, flowers. Fruit rot affects ripe fruits that become dry. Subsequently, the fungus can spread to the trunk.
The main "enemies" of culture are:
- Caterpillars of the subcortical leafworm... They make holes in the bark and wood, as a result, the tree slows down, the side branches dry out, and the yield decreases.
- Plum aphid... It settles on the July Rose in huge colonies, sucks juices from plants, causes a decrease in yield, sometimes - the death of fruit trees.
- Wrinkled sapwood... A small beetle, which "with appetite" absorbs all parts of the July Rose variety.
Timely prevention helps to prevent the manifestation of diseases:
- thinning the crown;
- removal of vegetation remnants under trees before winter;
- treatment of trees with 1% Bordeaux mixture (Hom mixture) before flowering and 2 weeks after flowering;
- treatment of trees with a 3% solution of copper sulfate in early spring before the start of sap flow.
Conclusion
Description of the cherry plum variety July Rose gives a general idea of the main characteristics of the plant. The fruit tree is characterized by early maturity, high winter hardiness, average drought resistance, high productivity and active fruiting. With proper care, ripe fruits are large and delicious.
