Growing and care
When the Jonker red currant variety began to be grown in Russia, suitable regions were selected: Northwestern, Volga-Vyatka, Central Black Earth. According to the description, the plant feels good in a temperate climate zone. Currants can withstand frost in winter or drought in summer. In the spring, when the air temperature fluctuates from minus to plus parameters, the surface around the bushes is mulched.
Selecting a location
For red currants of the Jonker Van Tets variety, choose a sunny place on the site. When planted in the shade, the berries do not have time to gain sugar and will turn out very sour. The harvest is also declining. A good location would be along fences or next to buildings. Plants cannot easily withstand northern winds.
When planting, take into account the height of groundwater. Red currants also do not like it when the water stagnates. If the site is located in a lowland, the planting places are made on a hill, and a thick drainage cushion is laid at the bottom of the hole.Then soil is poured into which humus or compost and wood ash are added.
The soil for Jonker Van Tets currants should be slightly acidic. The best option is loam and sandy loam soils.
Planting seedlings
Before starting work, seedlings are inspected for damage and disease. If there are signs of disease, it is better to refuse planting material. The seedlings are placed in water so that the root system is saturated with water.
In order for the plant to adapt faster after planting, the shoot is cut off by 2/3, and the leaves are also shortened. The seedling is placed in the hole at an angle of 45 degrees and watered abundantly. Then they cover it with earth. The soil is trampled down
How to plant red currants correctly:
Watering
Red currant variety Jonker Van Tets is described as a drought-resistant plant. Water it in the absence of rain 2-3 times a week. A bucket of water is poured under one bush.
In July and August the amount of water is increased. During this period, the fruits ripen on the bushes and flower buds are laid for fruiting in the next season. If there is not enough moisture, then not only the current, but also the future harvest may not be harvested.
Top dressing
For successful fruiting and a bountiful harvest, Jonker red currants are fed in the spring. At this time, the plants are fed with organic matter. Plants respond well to horse humus or humus. Be sure to add wood ash (100 grams per bush), which is then embedded in the soil when loosened.
Today, many gardeners refuse mineral fertilizers.But if they are used, then add the following nutrient mixture to each currant bush:
- double superphosphate – 70-80 grams;
- potassium sulfate – 30-40 grams.
Trimming
To obtain a stable harvest, red currant bushes of the Jonker Van Tets variety must be shaped. If pruning is done correctly, it will not only increase the yield, but also help the plant cope with diseases and pests.
Trimming Features:
- The bushes are pruned for the first time at the time of planting. The branches are cut by 2/3. Thanks to this procedure, the plant begins to bush and expels side shoots.
- In spring, pruning is carried out early, before the buds begin to swell. Remove frost-damaged or broken branches, and also trim the tops of the shoots by 5-6 centimeters.
- In the fall, after harvesting, old branches that have been bearing fruit for more than 4-5 years are cut out. Shoots with damage and disease must be removed. You need to cut the branches close to the ground so that there are no stumps left, as in the photo below.
- Red currant Jonker, according to the description and reviews of gardeners, grows greatly over the summer. That is why it is necessary to cut out excess growth so as not to weaken the bush.
If an adult bush is formed correctly, it should have about 15-20 shoots of different ages. Only healthy and strong branches are left for replacement. Experienced gardeners recommend rejuvenating the Jonker variety every year, removing the oldest shoots.
Cut shoots that are not damaged by diseases and pests can be used to propagate currants.
Diseases and pests
According to the description and numerous reviews of gardeners growing the Jonker Van Tets raspberry variety, the berry bush is resistant to many crop diseases. But you still can’t do without preventive treatments. This will help minimize damage to bushes by anthracnose and bud mites:
- For anthracnose, plants are sprayed with fungicides and antifungal drugs, Bordeaux mixture or copper sulfate. Any drugs are diluted in accordance with the instructions.
- As for the bud mite, to destroy it early in the spring, before the soil thaws, the bushes are watered with boiling water. You can treat currants with Fufanon before bud break. Spraying with colloidal sulfur gives a good effect. For a ten-liter bucket, 150 grams is enough.
To combat powdery mildew, aphids and caterpillars, you can use a folk remedy - infusion of onion peels.
