high palatability;
fruits ripen early;

high frost resistance;
undemanding and unpretentious.

Cons:

small fruit;
low immunity and disease resistance;
short shelf life;
need for pollinators.

Description of the early ripe variety Korobovka

Studying 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 shape of the crown remains pyramidal. After 20 years it becomes sprawling. A young plant gives a large increase, over the years it decreases significantly. The foliage is small, with slight pubescence.

Life span of a tree

With proper care Korobovka will live 50 years or more. Diligently bearing fruits that increase over the years.

Resistant to freezing temperatures

The tree is characterized by high rates of frost resistance and winter hardiness. For this reason, the variety is still grown.

Immunity to diseases

Korobovka is moderately resistant to scab, but for the prevention of diseases, treatment of plants with chemicals or folk methods of control is required.

Yield and pollination

The average volume of fruits from one tree is 50-60 kg. Subject to the rules of planting and agricultural practices, the yield from 1 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-infertile, therefore, to increase productivity, 2-3 trees are planted nearby, which bloom at the same time as Korobovka.

Best varieties:

White Pouring;
Chinese Saninskaya;
Cinnamon striped;
Paper;
Suyslepskoe.

Fruit tasting evaluation

Fruits weigh no more than 50 g. In terms of taste, they are not inferior to other summer varieties of apples. Often used to make juices, compotes and desserts.

Planting and proper care

Proper location on the site, proper planting, compliance with the requirements of agricultural technology helps to get a rich harvest from the fruit tree.

Preparing the seedling

An important condition for obtaining a crop is the selection and preparation of planting material. Seedlings for planting choose 1-3 years of age. Inspect for damage and deformation. Before planting, soak in a growth stimulator.

Required soil composition

Apple loves fertile land. With a lack of nutrients, the plant will not give a good harvest. It is recommended to grow on loamy or sandy soil. Before digging a hole for planting a seedling, humus, superphosphate and other mineral fertilizers are introduced into the ground.

Choose the best seat

Korobovka feels good in lighted areas, protected from drafts and strong winds. The depth of groundwater is not less than 3-4 meters.

It is advisable to choose a place where meltwater does not stagnate in spring.

Scheme and technology of disembarkation

The distance between trees is 3.5-4.5 m, between rows up to 5 m. A 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 fall asleep 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 lifting the tree. Thus straighten the roots and compact the earth. The root neck should remain 4-5 cm above ground level. At the end of planting, the earth is tamped and watered.

Water Regularity

Water the tree as needed, as the topsoil dries. In rainy periods, reducing the volume of water, in dry times, increasing it. On average, one adult tree needs 15 liters of water per week.

How and what to feed a tree

Fertilization is a crucial moment in the care of fruit trees. Gardeners advise that it is better to underfeed the plants than to overfeed them. At first, the seedling does not need anything. Then top dressing is alternated, introducing organic matter and mineral fertilizers.

Periods when plants need additional feeding:

early spring;
flowering period;
ripening period;
late autumn.

Timely rationing of fertilizers will help the apple tree grow strong, he althy.

Shaping the crown

An important method of agricultural technology for growing a fruit tree. Without proper pruning, the summer resident risks losing a significant part of the crop. The first year of the apple tree is not touched. Then cut off part of the side shoots, leave 5 strong, he althy skeletal branches. Subsequent years they are cut off by 1/3. Remove those shoots that grow inside the crown. Helping side branches form.

The procedure is carried out in the spring, before bud break, or in the fall after the leaf falls. Sanitary pruning involves the removal of dry, diseased and deformed shoots.

Insect and disease treatment

Spring work in the garden begins with preventive treatments for diseases and pests. Use chemicals before flowering. After using chemistry, it is dangerous to he alth, 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 for frost

Korobovka variety is resistant to frost. But summer residents, for their own peace of mind, cover the trunk circle with mulch. Use for this humus, peat, plant residues or sawdust. The thickness of the layer is 15 cm. It must be removed in the spring.
