Cherry Revna

Cherry Revna not so long ago appeared in the assortment of summer residents. However, the culture has already become very popular. Because the tree gives good yields and is resistant to frost, these characteristics make it possible to cultivate this cherry variety even in the cold climatic conditions of the Russian center.

A brief excursion into history

Cherry of the Revna variety is one of the varieties that was bred at the end of the twentieth century by breeders of the All-Russian Research Institute of Lupine. They called the cherry after the name of the river that flows in the Bryansk region, where the research institute is located. The cultivar "Bryansk Pink”, Bred a new variety by free pollination. The authors are scientists M.V. Kanshina, A.I. Astakhov.

In 1993, the Revna cherry variety successfully passed the state test, and since 1994 has been listed in the state register.

Fruits of medium size, dark red color, rounded, flattened. Fruit weight - 4.5-4.7 grams, in rare cases up to seven grams. The inner contents are compacted, dark red in color. The taste is sweet, the tasting score was 4.9 points out of five. The stone is easily separated from the pulp, medium size. The variety is universal in purpose. The fruits are well transported.

Drought and winter resistance.

Resistance to the winter season is one of the main goals in the selection of the Revna sweet cherry variety. In the end, everything worked out well. Cherry tolerates frosty temperatures up to minus thirty degrees.

Drought resistance is at a fairly high level. But it is still required to water the trees regularly, especially when the fruits are tied and ripen.

Cherry Revna: pollinators and flowering varieties

The flowering of the cherry variety Revna is quite early. In different territories, flowering begins in different ways, in middle latitudes it is observed on the 15th of May.

Cherry Revna is distinguished by partial self-fertility, however, if there are no plants nearby for pollination, then the yield will be small. For this reason, cherry trees are usually planted in groups. The best varieties for pollination: "Iput", "Tyutchevka"," Ovstuzhenka ".

Cherry variety Revna is medium late. As a rule, two and a half months pass from the time of flowering to the ripening of the fruit for harvesting. The sun accelerates maturation. Usually the fruits ripen by the last days of July.

Yield indicator, fruiting.

Revna begins to bear fruit from the fifth year. The tree yields consistently, high enough and every year. The average yield is fifteen to twenty kilos per cherry, if you take good care of the tree, it will bring thirty kilos of fruit and even more. The berries are small in size, but have good marketability, in rare cases they can crack.Since the fruit has a thickened skin, it can be transported well.

Where the fruits are applied.

The fruits have excellent sweet taste, they are often eaten fresh. But you can make compotes, preserves, confiture, jams from them. Since the fruits contain a lot of sugars (almost thirteen percent), you can make homemade wine from them.

Immunity to diseases and harmful insects.

Cherry variety Revna is affected by diseases in rare cases. For the most part, diseases appear if agrotechnical rules are violated (the crown thickens, excess watering), or the liquid stagnates in the soil. The greatest harm to the tree is caused by birds that are very fond of eating ripe fruits (among the people, cherry is often referred to as "bird cherry"). Of the pests, trees can often infect weevils or aphids.

Pros and cons.

Cherry Revna has few minuses. The most important of them is that the tree begins to bear fruit late, only from the fifth year. Compared to other cherry varieties, the culture we are considering ripens quite late, most gardeners say that this is a drawback. Another disadvantage is that plants are needed for pollination in order to get a decent yield.

Advantages.

• Small tree, compact crown.
• Good level of resistance to the winter season.
• Immune protection against common diseases caused by fungi.
• Excellent taste of berries, fruits are universal.
• The berries are well transported.
• It should also be said that fruiting is annual and stable, while the tree does not need to be looked after in a special way.

Cherry Revna: planting varieties

A characteristic feature of planting is that it is necessary to plant the variety in a group. Cherry seedlings of Revna must not be covered with other vegetation in order to avoid disturbances during cross-pollination.

Optimal planting time.

The recommended time for planting planting material is the spring season, after the soil thaws, but before the buds begin to swell. At this time period, the seedlings of the Revna cherry are at rest and can easily withstand the stress state associated with transplanting.

If time is lost, transplanting can be carried out before the hot weather sets in, but only plants with closed roots.

How to choose a suitable site.

Since a Revna cherry seedling is planted in a group way, then the site for planting is selected scrupulously. In order for a tree to grow and bear fruit normally, good sunlight and humidity are required, but swamps or areas with underground water passage above two meters are not suitable. Well suited for planting a sweet cherry tree in the south of the Upland. The site should be far enough away from fences and buildings, in addition, protected from cold winds, because the variety does not respond well to them.

The tree grows best on loams and sandy loams and on light, nutrient-rich soils with a neutral acidity level. It is forbidden to plant the variety on heavy clay soils.

What plants are prohibited and allowed to plant near a cherry tree.

• The cherry tree Revna is a fairly strong antagonist. It is advisable to plant a similar cherry tree close to the cherry, thanks to this, pollination will improve and there will be no conflict situations. Perfectly, cherry culture will coexist with cherry, which itself does not get along with other plants. It is forbidden to plant an apple, pear or plum tree nearby, they will interfere with cross-pollination.
• Flower crops grow well next to the cherry tree: nasturtiums, primrose. It is allowed to plant thyme. And there is no need to plant a nightshade crop (potatoes, tomatoes) in the root zone of a cherry tree, there will be no growth.
• Often, a black elderberry is planted with a cherry tree to prevent the appearance of aphids.

How to choose and prepare material for planting cherries Revna.

For planting, planting material 1-2 years old is suitable. When choosing Revna cherry seedlings, pay attention to the following rules.

• The planting material should have a well developed root system.
• The roots must not be dry.
• The graft area should be visible at the bottom of the trunk. If it is absent, then it is rather a seedling, and it will turn out to be a cherry tree without the characteristic features of the variety (wild).
• If the roots are still dry, then before planting they are placed in water for six to eight hours.

Planting progress.

• Planting pits are prepared, as a rule, in the autumn season. Holes should be spaced three meters apart. At the same distance or at a greater interval, the holes should be located from buildings or other trees in the garden. The hole should be 80-100 cm across, and 60-80 cm deep.
• The earth pulled out of the hole is preserved, mixed with humus, superphosphate is added (two hundred to two hundred and fifty grams per hole), then the mixture is poured when planting plants.
• A support is driven in the middle of the hole, and the plant is tied to it in the future. A substrate hill is poured into the middle of the hole, planting material is installed on it. The roots are straightened, covered with a nutritious substrate and lightly compacted.
• After planting, the root collar should be at the same height as the surface soil layer.
• After planting around the circumference of the Revna cherry seedling, a roller is poured out of the earth to retain water. After that, abundant watering is carried out (three to four buckets), then the trunk circle is mulched with humus, sawdust or peat.

Cherry Revna: leaving

To get a good yield, you need to correctly shape the crown of the cherry. For this purpose, a formative circumcision is performed, it is performed in several stages for the first few years. The formation, as a rule, of such varieties of the crown is carried out: sparse-tiered, flattened, bushy.

In addition to the formative one, it is required to systematically carry out sanitary circumcision, diseased, broken and dried branches are cut out.

To obtain a decent yield, the variety requires sufficient watering. If there is a lack of water, watering is carried out once every seven days. But such a drought happens in quite rare cases, the cherries usually have enough water from precipitation.

Feeding the plant is a very important agricultural technique. In the first 3 years after planting, top dressing is not applied, especially with good soil fertility in the territory. In the future, once every 3 years, organic substances (humus) are introduced into the soil for digging the trunk circle in the fall.

The plant is fed with minerals throughout the season. In the spring season, ammonium nitrate (3 stages) is introduced: before the tree blooms, after the cherry has faded, two weeks after the last feeding.

Twenty-twenty-five grams of top dressing is added to one square. In addition, in the summer, cherries are sprayed with a solution of potassium monophosphate.

Shelters are not built for wintering. The trunks and lower main branches are whitewashed to protect the bark from frost and sunburn. The trunk is tied with spruce branches to protect it from the attacks of hares and other rodents.

Cherries of the Revna variety: diseases and pests of the variety

Cherry Revna rarely gets sick. As a rule, diseases manifest themselves if the tree is illiterately looked after or because of bad weather.

• Hole spotting (clasterosporium disease). Symptoms: rounded specks of brown color appear on the leaves, rotting through and through, and holes are formed. How to deal, preventive measures: infected leaves break off and burned. In preventive measures, treatment is carried out with a one percent solution of Bordeaux liquid before and after flowering, as well as after two weeks.
• Mosaic. Symptoms: longitudinally to the veins of the leaflet, stripes of yellow color appear, then the leaflet twists, reddening and falling off. How to deal, preventive measures: infected leaves break off and burned. For preventive purposes, the same drugs are used as for spotting.

Of the harmful insects, the tree is often attacked: cherry fly, cherry aphid, fruit moth, cherry shoot moth.

The fight against enemies is carried out as follows: trees are sprayed with various poisons ("Decis", "Inta-Vir", "Karbofos"), the dosage is selected according to the recipe.

1.5 months before harvesting, any use of poisons ceases.

Cherry variety Revna is very popular among gardeners. All the advantages compensate for the disadvantages. And because of the excellent taste of the fruit, the variety occupies a leading position among garden plants.

I sell easily, the fruits are delicious, they fly apart once or twice. "

Danil Olegovich, 41 years old, Saratov regionb: Cherry Revna was planted 5 years ago, for the most part I wanted to experiment. I thought how the plants will take root, how they will survive the winter, since they are southern. I read a lot of reviews and took a chance. It turned out that he was afraid in vain. All 5 cherries in Revna have adapted. At the moment, the tree has already begun to bear fruit, but it is only a long time to wait 5 years. I am hoping that I was not mistaken. "
