How to prepare currants for winter?


Black currant fell in love with summer residents due to its unpretentiousness to the soil and the ability to survive freezing to -25 degrees without preparation.

But you can count on getting a full-fledged harvest only with timely care of berry bushes.

Is it necessary to cook black currants for winter in the Moscow region, in the Urals and in Siberia?

With proper care, it can produce yields up to 15-20 years.. The first few seasons of active fruiting summer residents can count on picking large berries without any extra work.

But with time bush grows old branches give meager harvest and hinder the access of sunlight to the young shoots.

Together with that soil depletion occursand there is a lack of nutrients in the plant. Branches and roots are damaged by pests and fungal diseases.

And with sharp frosts, you can lose not only a bountiful harvest, but also the bushes themselves.

Comprehensive preparation of black currants for winter carries a number of advantages:

  1. Increase yield.
  2. The absence of old branches allows young shoots to receive a sufficient amount of light. Berries grow larger and rich in vitamins.
  3. Digging helps get rid of pests, smooth out the effects of frost and retain moisture.
  4. The plant will be able to safely winter.
  5. From the improved bush it is much more convenient to harvest.
  6. Due to the regular "rejuvenation" he is able to bear fruit for up to 15-20 years.

How to help the berry bush to winter?

This will require to cut the bushes, prepare the soil, apply fertilizer and bend the branches to protect them from freezing and damage during strong winds.

Bending down the branches of a bush

Despite the high frost resistance of this garden crop, when the temperature drops below -25 degrees, shoots freeze and start to die. This can lead to a significant reduction in yield or even death of the plant.

To avoid this, you need to bend the branches to the ground. This can be done in several ways.

The easiest way is to crush shoots to the ground with bricks.. To do this, you need to group the branches in 3-5 pieces, alternately bend the bundles to the ground, put a board on them and press it with a brick.

To protect against freezing the currant branch can be pressed to the ground with bricks or non-metallic tiles

But better for that use non-metallic shingles, placing the stalks in its furrows. The branches grow in different directions, they need to be bent in this direction, having no more than 2-3 shoots in a row under one load. Otherwise they may be subject to excessive fracture.

Metal for bending the bush should not be used because it has a high thermal conductivity, which will contribute to the transfer of cold to the plant.

Burying. This method is used by gardeners who are faced with frosts below -35 degrees, when there is no snow layer on the soil. In this case, the plants need to cover with a layer of soil in 10 cm.

But, since the bush must be able to breathe, icing up this protective cushion can damage it.

Pruning in the fall

This the procedure is carried out after the leaves fall. The following branches are subject to removal:

  • dried and diseased;
  • old dark brown thick stalks;
  • superfluous, least strong young shoots. Thin branches will be harder to winter, they will become an extra burden on the root system.
Before wintering currants should be cut using a pruner, clippers and saws

For trimming old and thick branches may require the use of saws on wood, and for removal of young shoots there is enough secateurs or garden shears.

The tool must be sharp. This will not only make the cut place beautiful, but also save the plant from excessive damage. On the "treatment" of torn, uneven, broken off fragments of the berry bush will need a lot of energy.

Need to leave the strongest, fruit-bearing, non-shadowing stems, and young zero (root) shoots located near the main trunks.

Excessively thin branches will hardly survive the winter and will not delight the gardener with a high yield, and will only load the root system.

Pruning needs to be done off the ground.. When hemp protrudes more than 2–3 cm above the ground, they often re-grow.

Total bush should contain about 14-16 shoots. 3-4 stalks from 1 to 3-4 years old. Timely replacement of old stems with new growths will help maintain yields for many years.

Tops of zero shoots need to be shortened, as well as dying tips on older shoots. This will contribute to abundant spring branching.

Pruning is also needed as a preventive measure against fungal and other diseases. Removed residues are recommended to burn.

Pruning of black currant bushes in autumn:

Fertilizer and soil care as a preparation for wintering

First you need to prepare and clean the soil around the bush from old mulch and leaves that are a breeding ground for pests, fungal and viral diseases.

The leaves will need to burn or put in a compost pile, away from the berry bushes.

For soil disinfection You can use the solutions of the following drugs:

  • copper sulphate;
  • 0.3% solution of copper oxychloride;
  • potassium permanganate;
  • 1% Bordeaux liquid.

If the currant bush is abundantly sprayed with a solution of urea (urea) before falling off, you can get rid of a lot of bacteria and fungi. For its preparation, it will be necessary to dissolve 100 grams of urea in 10 liters of water.

It is necessary to clean the soil around the bush from old mulch and leaves, which are a breeding ground for pests, fungal and viral diseases.

After cleaning the soil from organic remains and its decontamination you can go to digging. If you do this before the frost, you can get rid of many pests that hibernate in the upper soil layer.

Digging is carried out with garden forks. It should be combined with the introduction of 10 kg of organic matter. Light soils can be “plowed up” with special rippers.

Directly near the base of the bush, the ground can be dug to a depth of 5-6 cm, along the perimeter - up to 15 cm. It is important not to damage the roots.

If the soil is dense, its clumps need to be crushed with forks and rakes. Then the soil can be disinfected once more by spraying it with one of the previously described solutions.

Fertilizing with mineral fertilizers produced before digging, along with it, or sprinkle fertilizer around the bush before precipitation, putting it in the ground with a ripper or a rake. In autumn, only phosphorus and potassium can be applied to the soil.

Superphosphate (50-80 grams) can be used as a phosphate dressing. Potassium sulphate is also introduced (20-40 grams).

Wood ash contains potassium, phosphorus and many other elements, so you can replace it with mineral fertilizers or supplement them. Under the bush during digging you will need to make 100 grams (250 ml) of the substance. It can be diluted in water and immediately pour liquid over the ground.

The ash must be crushed before entering into the soil. It cannot be used together with nitrogenous fertilizers: carbamide, droppings, manure. Ash can be stored for many years, but only in a dry state, being, for example, in a closed bank.

Before digging into the soil, it is necessary to add wood ash, which contains phosphorus and potassium.

Fertilized and loosened soil should be covered with fresh mulch.: compost, sunflower husk, rotten sawdust or leaves of non-crop crops in which there will be no pests threatening currants. It will save the bush from frost and prevent rapid loss of soil moisture.

The mulch needs to be scattered before the soil freezes. Otherwise, the protective layer forms a kind of refrigerator, which will interfere with the heating of the soil during warming.

When snow falls, you need to throw it on the berry bush and around itand lightly tamp. In the absence of it, the plant can be sprinkled with forest foliage, needles or covered with agrofiber.

Competently prepare without making mistakes

It is worth highlighting a few common mistakes. gardeners that they do with this:

  1. Introduction of fresh manure to the bush. Excess nitrogen contained in it, will cause the plant to thrive, which will adversely affect its preparation for the winter. This will make the bush more susceptible to cold weather. Manure can be spread under currants only after the onset of stable cold weather.
  2. Covering the bush with plastic wrap and other synthetic materials. Without air access, the plant often dies.
  3. Breaking off branches with hands, nippers and cutting them with a knife weakens the bush.
  4. Late application for currants, when it has already completed fruiting, high doses of organic matter. This leads to an abundant build-up of green mass and the laying of a small number of flower buds. The plant develops rapidly until the beginning of frosts and do not have time to prepare for them.

In Moscow, in the Urals and in Siberia with the first signs of the onset of spring, it is necessary to free the bush and let its stem develop and dissolve the buds.

Excessively long bush under cover will make it impossible to form enough organic matter to produce a bountiful harvest.
