Advantages and disadvantages of the variety

Pros:

high productivity;
rich in vitamins;
used both raw and processed;
excellent taste;
immune to powdery mildew, anthracnose and bud mites;
prevention of cancer due to beneficial microelements in the composition.

Minuses:

Early flowering. The ovaries may suffer from spring cold, you need to monitor the temperature.
It grows quickly and requires control (pruning, replanting, etc.).

You will be able to reap a rich harvest if you put into practice knowledge about the intricacies of planting and caring for the plant.

Transfer time

In order to propagate and plant red currant bushes correctly, you should first decide on the most suitable method for you:

green cuttings. Carried out mainly in early summer. The cuttings are cut in the morning and placed in water, having first made cuts in the bark in two internodes. The next stage is burying the cuttings in the ground. It is recommended to cover them on top with a jar or film. The main thing is to provide complete care for the shoots. They need to be watered regularly, and also remove the jar from time to time to ventilate the cuttings. When the first leaves appear on them, the cover can be removed. If at the end of summer you can safely say that the cuttings are strong and ready for planting in the ground, this can be done this fall. Otherwise, leave the cuttings in the soil until spring;
lignified cuttings. This procedure is carried out in early to mid-August. The shoots must be immediately planted in a permanent place. Until next spring, it is recommended to regularly water and hill up the seedlings. If you do everything correctly and the cuttings have time to take root, they will be able to wait out the winter cold without any problems;
combined cuttings. At the end of May and beginning of June, seedlings are harvested. Once you bury them in the ground, they can take root within two weeks. Before this, you prepare them directly on the bush.

Which method and period of plant transplantation will be most optimal for you depends on how well you understand this or that method.

Landing Features

Seedlings selected for planting:

1–2 years old;
with a healthy root system;
barrel without damage;
wet buds or green leaves.

You can grow currants from cuttings or by grafting yourself.

It is recommended to plant bushes nearby, this increases the overall yield. But keep a distance of at least 1 m between them. A standard planting hole has a depth of 5–10 cm. There is no need to pollinate currants artificially.

The ideal soil for planting is sandy and loamy. Groundwater should not touch the roots. Experienced gardeners recommend planting bushes near the fence so that the wind does not damage them. The area should be open to the sun, then the currants will be nourished by warmth, the fruits will be filled with vitality. In the shade, the berries will become small and sour. The proximity to other fruit-bearing bushes (gooseberries, black currants, raspberries), as well as vegetables and herbs (dill, parsley, etc.) is favorable. Garlic and onions nearby will protect the currants from pest attacks.

How to plant correctly:

Dig a hole measuring 40x50 cm.
A bucket of humus, 300 g of ash, peat, sand, 100 g of superphosphate, 100 g of potassium sulfate, mix with soil.
Fill the hole ⅔ full with the mixture.
Plant a bush in the prepared hole.
Cover with earth.
Add two buckets of water.
Sprinkle the base with peat or sawdust.

The right nutrient medium will give the plant the strength it needs to grow.

Plant care

Water the plant in the early stages of growth in the morning and evening. 1 currant bush requires 10 liters of water. In the spring, you can slow down the pace, and after the ovaries appear, start abundant watering again.

They begin to fertilize the soil after the shoots begin to grow, with the end of winter. Composition of the standard mixture:

organic fertilizer and 15 g of urea;
after 2 weeks, add 40 g of superphosphate to the mixture;
after another week, 20 g of superphosphate, 20 g of ammonium nitrate and 15 g of potassium sulfate are combined and transferred to a bucket of water.

The bucket is enough for 2 bushes. When the soil is depleted, special fertilizers rich in microelements are used. If nothing helps and the currant bush does not take root, then it is necessary to transplant it to another area.

Transplant methods

Method 1	Beginning August - Mid. August, plant the cuttings in a free place, care for them until spring, observing the appearance of roots.
Method 2	Beginning summer, take cuttings, cut off the bark at the base, cut twice in the internodes, put in a jar of water, plant in the ground, cover with film (sometimes remove for ventilation), after the leaves appear, remove from the jar and film.
Method 3	con. May - beginning In June, seedlings are prepared, planted and waited; after planting, it is necessary to cut off half of the shoots, and in the spring, remove the old shoots again.

To keep Jonker van Tets intact until next year, you need to mulch the soil before the onset of frost. Horse humus is used for this. For the winter, the plant is covered with burlap and/or spruce branches, protecting them from the cold. As an option, you can use Spunbond material for cover in this way:

tie the bush with a rope so that the branches do not fall apart;
put a bag on top;
secure it with pegs so that it does not fly away from strong winds.

It is recommended to pre-treat the plant against parasites and infections.

Agricultural technology

Even a novice gardener can cope with growing Jonker Van Tets red currants, since the bushes do not require specific care. Before planting, it is necessary to select high-quality seedlings and correctly carry out the procedure for rooting them on the site. Further care includes regular watering, fertilizing, annual pruning and preparation for wintering, as well as preventive measures to combat pests and diseases.

Choosing a place and landing

The Jonker Van Tets variety can be grown in areas with cold winters and dry summers, choosing a suitable place for planting with optimal conditions for annual fruiting of the bushes.

Basic requirements for the planting site:

good access to sunlight - plants need light for normal growth and uniform ripening of the crop, as well as for saturating the berries with sugar;
light and loose fertile soil of neutral acidity - it allows moisture, air and sunlight to pass well to the branched root system of the bush;
protection from cold wind - in a draft, the plant grows and bears fruit worse, and is more often affected by diseases, so it is recommended to place currant seedlings on the south side of buildings or fences;
the presence of groundwater at a depth of at least 2 m from the ground surface - the root system of the bushes reacts poorly to excess moisture and can rot;
the presence of suitable neighboring crops - red currant grows well and bears fruit next to gooseberries, vegetables, onions, garlic and herbs, but it is not recommended to plant it next to black currant bushes or other berry crops that form root shoots.

Did you know? Using red currant juice, you can quickly whiten your skin and fade freckles on your face.

It is recommended to plant seedlings of the Jonker Van Tets variety in September or early October so that the plants take root before frost and begin to grow in the spring. If a gardener purchased young seedlings with a closed root system in February, then it is best to plant them in the summer to avoid temperature fluctuations and sunburn on the surface of young bushes. Until planting, such seedlings should be kept in a greenhouse or in a well-lit living room.

The site preparation procedure begins approximately 1-2 months before planting seedlings and includes the following actions:

digging up the soil to a depth of about 50 cm and removing all plant debris and debris;
enrichment of the soil with nutrients in the amount of 8 kg of compost, 100 g of superphosphate and 80 g of potassium sulfate per 1 m² of area;
digging planting holes with dimensions of 50x50x50 cm - the distance between adjacent recesses must be at least 1.5 m;
It is recommended to add 1 handful of humus and wood ash to the bottom of each hole.

Important! For planting, you need to choose healthy seedlings up to 40 cm high with a smooth trunk, 1-2 branches and a branched root system consisting of elastic roots.
A step-by-step algorithm for planting young bushes is presented below:

Before planting, soak the roots of the seedling in a container of water for several hours. You can add a little root growth stimulator to the water.
Immerse the roots of the seedling into the planting hole, placing the bush at an angle of 45° to the surface of the earth. The root collar should be 5–8 cm below the soil surface.
Sprinkle the roots of the bush with loose soil, periodically compacting it with your hands to eliminate voids.
Press down the soil around the bush with your hands to form a circle around the trunk. Border it at the edges with an earthen roller of medium height.
Water each seedling with 1 liter of warm water to moisten the soil.
After complete absorption of moisture, mulch the area around the tree trunk with dry straw.

Care

Jonker Van Tets currant bushes are unpretentious in care, but to achieve high yields they need moisture and fertilizers. Therefore, it is necessary to apply fertilizing in a timely manner and prevent the soil around the plants from completely drying out, adhering to a certain watering schedule.

Important! To ensure that moisture evaporates less and is retained in the soil longer, it is recommended to water Jonker Van Tets red currants in the morning or evening.
Basic rules of care:

It is recommended to irrigate the bushes every 4-5 days, but if there is a drought at the stage of ripening the berries and after picking the berries, then water the currants once every 3 days, spending 10–20 liters of water on each bush;
during watering, water is poured into small grooves dug at a distance of 35 cm from the stems of the plant - this way it is evenly absorbed into the ground and gets to the roots faster;
in April, each bush is fertilized with a mixture of 10 liters of rotted manure solution and 15 g of urea - this fertilizing stimulates the growth of shoots and the growth of lush green mass;
14 days after applying organic fertilizing, the bushes are watered with a solution of 10 liters of water, 20 g of superphosphate, 15 g of potassium sulfate and 15 g of urea;
20 days after the second fertilization of currant plantings, a nutrient mixture of 5 liters of water, 10 g of ammonium nitrate, 10 g of superphosphate, and 8 g of potassium sulfate is added to each plant;
the soil in the beds with plants must be periodically cleared of weeds and loosened to a shallow depth - this facilitates access of water and fertilizers to the currant roots;
It is recommended to mulch the tree trunk area with humus after each watering - this will stop the growth of weeds and help keep the soil loose longer.

Disease and pest control

Bushes of the Jonker Van Tets variety have stable immunity, so they rarely suffer from infections and pests. But if there are errors in care or as a result of planting plants in the wrong place, currants may be attacked by insects and get sick.

You may find this information useful on how to treat currants with Bordeaux mixture in the spring.

Most often, plants are affected by the following infections and pests:

Powdery mildew. The symptom of this fungal disease is a white powdery coating on the surface of the leaves. Over time, it acquires a brown color and causes yellowing of the entire green mass of the bush. In this case, the fruits do not ripen, and the crop yield is significantly reduced. You can get rid of the disease using special chemicals (for example, Aktara or Actellik).
Anthracnose. Symptoms of the disease are small spots on the leaves that resemble burns. Over time, they capture the entire surface of the leaf blade, causing the green mass of the plant to dry out and fall off. For treatment, use a 1% solution of Bordeaux mixture, irrigating the bushes with it before and after flowering.
Glass rust. The main symptom of the disease is bright orange spots on currant leaves, which gradually increase in size and lead to curling of the leaf plate. The bush can completely dry out and die, so when affected leaves are found, they are torn off and destroyed. To treat goblet rust, use a 1% solution of Bordeaux mixture or special chemicals (for example, Topaz).
Kidney mite. The pest lives inside the fruit buds of currants, as a result of which they become swollen and round, and subsequently deformation of the apical leaves on the bush occurs. To stop the spread of the pest, you need to cut off all the affected buds from the bush and destroy them. After this, the currants must be sprayed with a garlic solution (150 g of product per 10 liters of water) or an insecticide (for example, Actellik).
Currant glass. The pest attacks the inside of the plant shoots, feeding on wood, so its appearance can only be noticed after 1 year.
Affected currant branches begin to lag in growth and dry out, and the leaves growing on them wither and the fruits fall off. All dried shoots must be cut off and destroyed, and the currant bushes must be treated with a mixture of insecticides and fungicides. Did you know? The leader in growing red currants is Russia - about 60% of the world's volume of these berries is produced here.
Leaf gall midge. A sign of the appearance of this pest on currant bushes are red swollen formations on the lower surface of the leaf blade. The leaves begin to turn yellow and dry out, which negatively affects the yield of the bush. The affected areas of the plant need to be cut off and burned, and the plantings should be treated with Karbofos solution.

To prevent all of these problems, it is recommended to implement the following preventive measures:

follow the recommended bush placement pattern;
regularly weed the tree trunk area;
choose high-quality planting material for planting;
Perform annual pruning of the bush;
follow watering and fertilizing schedules;
perform autumn digging of soil around plants.

Pruning and shaping the bush

The tall bush of the Jonker Van Tets variety requires mandatory pruning. This procedure not only helps to give the crown of the plant a compact shape, but also ensures uniform access of the sun's rays to all branches and fruits, which has a beneficial effect on the taste and marketability of ripe berries.

Features of pruning bushes:

the branches of a young seedling are cut to half their length immediately after planting to stimulate the growth of new lateral shoots;
in April, before the start of sap flow, frozen and damaged stems are removed, and healthy shoots are shortened by 5-6 cm;
In the fall, sanitary and rejuvenating pruning is carried out - for this purpose, shoots that have bear fruit for 5 years are completely removed, as well as branches growing inside the bush and intertwined dense shoots;
the total number of stems in the bush should not exceed 15 pieces, and it is recommended to remove excess and old shoots gradually - 1-2 branches per year.

Wintering

This variety of currants has good frost resistance, but requires winter shelter. Preparing a plant for winter begins in the fall after harvesting and includes the following sequence of actions:

clean the tree trunk area from debris and fallen leaves;
dig up the soil around each bush with the addition of 100 g of superphosphate and 50 g of potassium chloride;
at the beginning of October, carry out pre-winter moisture-recharging watering of the plant - the ground should get wet to a depth of at least 40 cm;
cover the soil around the bushes with a thick layer of compost to protect the roots from freezing;
tie the currant stems with a rope in a spiral so that the shoots form a vertical bunch;
pull a fabric bag over the tied branches of the bush, securing it with a rope, and for additional stability, you can drive a peg next to the currants and tie the covered bush to this support.

Important! Before storing red currants, you should not wash them, because contact with water causes the berries to lose their shape and release juice.

Diseases and pests: table

Despite the fact that Jonker van Tets bushes are not prone to disease, prevention will not be superfluous.

Name of disease/parasite	What to process	What does it look like externally
Anthracnose	Copper sulfate, Bordeaux mixture, “Prognoz”, “Chistoflor”, “Fitosporin-M”. Apply before leaves appear	Looks like a burn
Mite	Boiling water, “Fufanon” (can be used only before the appearance of leaves and flowers), colloidal sulfur (150 g per bucket of water)	Large swollen leaves
Caterpillars, powdery mildew, aphids	Onion water (infusion on the peel), solution of soda and soap, “Nitrafen”, “Karbofos”, “Inta-Vir”. Spray periodically for prevention	Leaves are damaged

All measures to destroy pests using chemicals must be completed with the appearance of the first berries.

Harvesting

According to reviews from summer residents, this variety is one of the most fruit-bearing; ripening lasts up to 3 weeks. Jonker van Tets produces approximately 6–7 kg of berries from one bush. The first harvest can be observed in July. They do not pick the berries one at a time, but with a full brush, so they remain intact.

It is recommended to harvest in dry weather; rain and dew spoil the quality of currants. A small container of 2–2.5 kg is suitable for harvesting so as not to crush the fruits. You can only store it dry or frozen, otherwise the berries will spoil.

The fruits of Jonker van Tets are used for jam, marmalade, fillings in baked goods, and sauces. The rich, sweetish taste allows you to enjoy eating them straight from the bush.

The maximum time for planting this variety of red currant is early autumn in central Russia, mid-November in the south. Then they will have time to take root before the frosts begin and will calmly survive the winter. The variety is perennial, the richest harvest is harvested in 5–8 years. Life expectancy is 20 years.
