    To prevent black currants from burning

    Black currants are very sensitive to heat. Young plantings suffer the most. And this is mainly due to overheating of the soil in the root zone, which are simply "boiled". Mature bushes have their own problem: in the strong sun, some of the berries are baked.
    To protect the cuttings from attacks, I put a shading net in the schools, and the cornices near the fruiting bushes save the berries from baking.
    Berries will also protect thickened plantings from scorching rays. I plant my currants according to the scheme 80-90 × 120 cm. The bushes are powerful, so the bulk of the crop is in the shade (no more than 5% "burns" in the sun). Thickened plantings also save from overheating of the soil (there is always a shadow under the bushes).

    So that the roots do not overheat, I advise you to cover them with mulch with a layer of at least 7 cm.
    An interesting solution to the problem was found by my friend, who lives in the southern region. It places rows of black currants strictly from west to east. The greatest sun load goes to the first row, and in the rest the soil is constantly in the shade.

    A very dangerous disease of blackcurrant is terry, or reversion. It is easier to identify it when the currant blooms.

    If the flowers instead of the usual golden-green petals show elongated, ugly, dissected inflorescences of violet color, if the leaves are small, the plates are divided not into 5, but into 3 lobes, if there is no specific smell of currant, there is every reason to believe that the bushes are affected by the terry .

    Unfortunately, this viral disease is not treated, but it can be prevented. In case of infection, it is necessary to remove and burn the entire bush so that the disease does not spread to other plants.
    It is known that pathogens are mainly transmitted by kidney mites. The most famous way to deal with them is early spring (early March) treatment of currant bushes with hot water (up to 80 degrees). Consumption -10 liters per 2-3 bush.
    You can add several crystals of potassium permanganate to the water or a pinch of copper sulfate. This will be a good preventive measure against fungal diseases.
    There are relatively resistant to terry varieties of black currant: Memory of Michurin, fertile Leah, Zhelannaya, Neapolitan, Brilliant, Primorsky champion. But in order for them, and other varieties to be able to repulse viruses, it is necessary to increase the immunity of plants. Regular top dressing of currants under the root of potassium-phosphorus fertilizers helps to achieve this. If you spray the leaves with nutritious mixtures, you should pay attention to the composition of the fertilizer: it should contain molybdenum, boron and manganese. After collecting the berries, the currant bushes are treated with colloidal sulfur or Karbofos.

    Note
    The appearance of terry can provoke a fascination with nitrogen fertilizers. It is necessary to carefully observe the dosage of such mixtures and in no case exceed it.

    Green “balls” appeared on two bushes of black currant. I cut them off, and the branches, on which there were especially many “balls”, cut off. What is it?

      - Rounded buds (green "balls") at the time of blooming of black currant - this is an indication that the plants are damaged by kidney mites. You did everything right, but if the bushes are more than 5 years old, I advise you to completely uproot and burn them.

      - The lighter (yellowish) color of the tops of the growth of black currant is a characteristic feature of actively growing plants, not associated with any disease.
