Description
Leading pomologists of the world conducted a number of studies and came to the conclusion that the Renet Semerenko apple variety is truly unique, since it cannot be seen in any of the European collections. The features of this variety can be safely called the early fruiting period, high yield and high quality of fruits, which are then preserved quite well. What is the description of these trees? As you can see in the photo, the Renet Semerenko variety is quite tall trees with a spreading dense crown, somewhat resembling a cauldron in shape.
The bark of the branches and the trunk is distinguished by a dark gray tint, and if the sun's rays fall on it, it becomes orange. The Renet Semerenko variety also has a mixed type of fruiting. The shoots of the apple tree are straight or slightly curved, have an average thickness, and also have rare lentils. The description of the leaves is also typical for the variety - they are round, with a slightly elongated top, slightly wrinkled in the middle, have one- or double-toothed edges. The pubescence of leaves, the plate of which is curved at an angle of 90 degrees, is light and medium. They are light green in color.
If we talk about flowers, then in the Renet Semerenko variety they are white, shaped like saucers, the column of pistils has no edge. The fruits of this apple variety are large in size, and the shape may have a slightly asymmetric, up to flat-rounded (which is also clearly visible in the photo). During ripening, the fruits have a characteristic light green color with light subcutaneous spots. The main distinguishing feature of the variety can be called warty formations, reaching about 7 mm in diameter.
The fruits of the Renet Semerenko variety have a rich pleasant taste, and the pulp of such apples is white and juicy, with a spicy taste. The chemical composition of the fruits is as follows - they contain about 7, 5 - 12% of sugars, 0, 4 - 0, 7% of titratable acids, about 7 - 9 mg of ascorbic acid per 100 grams. Naturally obtained, this apple variety is late winter.
Specificity of care
To get a good harvest from Renet Semerenko's apple tree, you should provide it with good conditions and proper care. It includes such activities as regular watering of the tree, feeding with special fertilizers, timely pruning, as well as competent preparation for wintering. In addition to watering, immediately after planting with three to four buckets of water, the tree must be watered periodically - about three times per season, 3 - 5 buckets per tree, in order to prevent the soil from drying out excessively. 
Watering should only be stopped by the end of July so that the tree can prepare for winter. To fertilize trees of this variety, manure is added to the soil in the fall; you also need to buy mineral fertilizers in a specialized store.
It is important to know that in the spring it is necessary to provide the trees with nitrogen fertilizers.
On the surface, it is recommended to decompose ammonium nitrate or ammonium sulfate. Phosphorus dressings have also worked well, which should be added to grooves with a depth of about 30 cm. Humus, compost or peat are used for mulching.This type of care is good for trees that have a shallow root system. To prevent hares from gnawing tree trunks, they need to be tied. This procedure is done annually until a dense bark appears on the trunk. Still the trunks of apple trees of the Reneth variety Semerenko are advised to whitewash.
Since the trees have a luxurious crown, in order not to harm good fruiting, the shoots should be pruned during the care process. It is necessary for all varieties, which are characterized by a very developed ringlet, as well as for low-growing trees. In young apple trees, only those shoots that have a length of at least 60 cm should be cut off. This procedure will help to maintain a one-year growth in a normal state, where most of the apples actually appear.
This variety firmly tolerates both strong winds and heat, but at the same time it does not really welcome cold and frost. Therefore, it is necessary to cover the roots starting in the fall. To prevent the appearance of troubles in the form of scab or powdery mildew, thinning of the crown is done. Old and damaged leaves, fruits, branches are recommended to be burned at the end of the season.
How to propagate
There are two ways to reproduce an apple tree of this variety - by seeds or by cuttings. Propagation with seeds is carried out mainly in order to obtain a new variety of tree. In order to get it, pollen from one tree is transferred to the flowers of another, and good fruits will not appear there so quickly. And for a good sample, you will have to look at many individuals. That is why an easier way, which is successfully used today, is propagation with green cuttings. In this case, each of the new apple trees will have its own roots, and if suddenly the above-ground part of it dies, then self-recovery can be expected.
When the cuttings reach the desired length, they are cut off - during this period they are still elastic. The best period for harvesting cuttings is considered the middle or end of June. On the handle, it is necessary to make a neat cut with a knife about 10 cm long so that there are at least 4 sheets on the shoot. The stalk is lowered by a third into the prepared heteroauxin solution, where it should stay for about 10 hours. The solution is made at the rate of one and a half tablets per liter of hot water. It is necessary to prepare the soil, for this they use leafy or humus soil, on which a peat-sandy substrate should be placed. Cuttings are planted in mini-greenhouses 4 cm deep. The distance between them should be about 5 cm, and between the rows - 10. To grow the cuttings, they are seated in different containers or in a permanent place.
Who opened
Those gardeners who are going to buy and plant this beautiful apple variety, of course, are interested in who discovered Semerenka. The name of the new type of apples was given by the famous breeder Lev Platonovich Simirenko, who lived in the village of Mleevo in Ukraine. It was there that the scientist created his fruit nursery, and the apples got their name in honor of the breeder's father, Platon Simirenko. The ancestors of Lev Platonovich, former serfs, were able to redeem themselves from the owners and even became respected people in the circle of merchants.
Lev graduated from the Novorossiysk University in Odessa, but his participation in the "People's Will" movement was exiled to Krasnoyarsk. There he managed to work in the greenhouses of local wealthy people and became famous for being able to breed heat-loving southern crops in the harsh Siberian climatic conditions. In memory of its creator, a city park still exists in the city of Krasnoyarsk. Simirenko was the first to create this variety of fruit trees in Russia. The great scientist dedicated one of the three volumes of his famous book "Pomology" to the apple tree. And for his services, Simirenko was awarded a high award - a gold medal, which was presented to him at the international Paris exhibition.
