The culture is widespread in the gardens of many summer residents. It is important to select the variety that meets the family's needs. The Korobovka apple tree has more than one year of planting experience behind it. During this time, she showed herself as an unpretentious type of fruit tree.
The history of the creation of the variety
The first scientific description of the variety dates back to 1855. The species got its name because it was sold in boxes, like berries. Created by S.I. Isaev together with M.P. Maximova.
Was born as a result of crossing:
- Wesley;
- Brown striped.
Korobovka is not common for industrial cultivation, since the fruits are small. But often this species is used to create a new frost-resistant variety.
Advantages and disadvantages
Like other types of fruit trees, Korobovka has a number of positive and negative characteristics. After reviewing them, the summer resident decides whether to plant a tree on the site or not.
Pros:
- high taste characteristics;
- fruits ripen early;
- universality of use;
- the tree bears fruit for 45-50 years;
- high frost resistance;
- undemanding and unpretentiousness.
Minuses:
- small fruit;
- low immunity and resistance to disease;
- short shelf life;
- the need for pollinators.
The variety is rarely grown in plots, but it deserves attention, as it is the mother of many summer varieties of apple trees.
Description of the early maturing variety Korobovka
The study of the characteristics of the variety will help the summer resident to choose the right place for planting, to take proper care of the plants.
Region of natural growth
The apple variety is old, so it is found in many gardens. Korobovka is widespread in Russia, Ukraine, Belarus and other countries.
External parameters
The tree grows up to 6 m. For some time the crown shape remains pyramidal. After 20 years, it becomes spreading. A young plant gives a large increase, over the years it decreases significantly. The foliage is small, with slight pubescence.
Tree life
With proper care, Korobovka will live 50 years or more. Diligently bearing fruit, which grows over the years.
Resistance to subzero temperatures
The tree is characterized by high rates of frost resistance and winter hardiness. For this reason, the variety is still grown today.
Disease immunity
Korobovka is moderately resistant to scab, but prevention of diseases requires treatment of plants with chemicals or folk methods of struggle.
Productivity and pollination
The average volume of fruits per tree is 50-60 kg. Subject to planting rules and agrotechnical techniques, the yield per plant reaches 70-75 kg.Every year there are more apples on the tree. They will not be smaller, and the taste characteristics will not change.
The variety is self-fertile, therefore, to increase yields, 2-3 trees are planted nearby, which bloom at the same time as Korobovka.
The best varieties:
- White filling;
- Sanin Chinese;
- Cinnamon striped;
- Folding;
- Suislepskoe.
Fruit tasting evaluation
Fruits weigh no more than 50 g. In terms of taste, they are not inferior to other summer varieties of apples. They are often used for making juices, compotes and desserts.
Planting and proper care
Competent location on the site, correct planting, compliance with the requirements of agricultural technology helps to get a rich harvest from a fruit tree.
Preparing the seedling
An important condition for obtaining a harvest is the selection and preparation of planting material. Seedlings for planting are chosen at 1-3 years of age. Inspect for damage and deformation. Before planting, they are soaked in a growth stimulator.
Required soil composition
The apple tree loves fertile land. With a lack of nutrients, the plant will not give a good harvest. Recommended to grow on loamy or sandy loam soil.Before digging a hole for planting a seedling, humus, superphosphate and other mineral fertilizers are introduced into the ground.
Choosing the best place
Korobovka feels good in lighted areas, protected from drafts and strong winds. The groundwater depth is at least 3-4 meters.
It is advisable to choose a place where melt water does not stagnate in spring.
Disembarkation scheme and technology
The distance between trees is 3.5-4.5 m, between rows up to 5 m. The planting hole is dug 0.6-0.8 m deep, 1-1.2 m wide. A peg is driven in the center of the planting hole. It serves as a support for a young tree.
A drainage layer is formed at the bottom. Then they are covered with fertile soil. To do this, mix humus, wood ash, mineral fertilizers. Then a hill is formed on which the seedling is installed.
Gradually sprinkle with earth, periodically raising the tree. Thus, the roots are straightened and the earth is compacted. The root collar should remain 4-5 cm above the ground. At the end of planting, the earth is tamped and watered.
Regularity of watering
Water the tree as needed, as the topsoil dries up. In rainy periods, reducing the volume of water, in dry seasons, increasing it. On average, one adult tree needs 15 liters of water per week.
How and what to feed the tree
Fertilization is a crucial moment in the care of fruit trees. Gardeners advise that it is better not to feed the plants than to overfeed them. At first, the seedling does not need anything. Then the fertilizing is alternated, introducing organic matter and mineral fertilizers.
The periods when plants need additional nutrition:
- early spring;
- flowering period;
- ripening period;
- late fall.
Timely rationed fertilization will help the apple tree grow strong, healthy.
We form the crown
An important technique for growing a fruit tree. Without proper pruning, the summer resident risks losing a significant part of the crop. The first year the apple tree is not touched. Then part of the lateral shoots is cut off, 5 strong, healthy skeletal branches are left. Subsequent years they are cut by 1/3.Remove those shoots that grow inside the crown. Helping the side branches to form.
The procedure is carried out in the spring, before bud break, or in the fall after the leaf falls. Sanitary pruning involves removing dry, diseased and deformed shoots.
Insect and disease control
Spring work in the garden begins with preventive treatments for diseases and pests. Use chemicals before flowering. After using chemistry it is dangerous to health, since particles of the substance remain in the fruits. During this period, they use folk remedies to combat viruses and insects.
We cover the apple tree to frost
The Korobovka variety is resistant to frost. But summer residents cover the trunk circle with mulch for their own peace of mind. Humus, peat, plant residues or sawdust are used for this. The layer thickness is 15 cm. It must be removed in spring.
Apple tree Korobovka has been known to gardeners for a long time. On its basis, summer varieties of apples with high winter hardiness have been created. In addition, the tree is unpretentious and undemanding to care for.
