Many do not know that treating currants in spring with boiling water gives excellent results in the fight against pests and ailments. After all, it is very difficult to control parasites on a plant - they appear together with young foliage, and it takes an enormous effort to save the harvest all summer.
Treatment of currant bushes in spring with boiling water
The most dangerous pest of the currant is the currant bud. About its presence is shown by large sprouts, which look like small light heads of cabbage. Kidney mites and other parasites settle on the plant in the autumn and winter on it. When the bush starts to wake up, the females lay eggs and on the branches appear disfigured bitten leaves, new shoots develop poorly. In autumn the mite again settles in the kidneys and everything repeats. Watering the currant with boiling water in early spring will help to stop the process of reproduction of the parasite, to destroy the larvae of aphids and fungi.
Why water the currant with boiling water in the spring?
The impact on the currant of steep boiling water solves several problems at the same time:
- With the care of the currant in the spring, pest control occupies an important place. Watering with boiling water will help to completely eliminate the kidney mite, powdery mildew , aphids. The procedure will help to destroy harmful microorganisms, pest larvae, which may be under the bark or in the soil near the plant.
- Currant processing in spring with boiling water stimulates the plant's immunity and increases its susceptibility to bacteria. The bushes experience a peculiar stress, as a result of which their productivity, appearance, commodity and flavor qualities of berries are improved.
- The shower of boiling water warms the bush and accelerates the awakening of the kidneys from winter rest.
- After irrigation, the number of peduncles increases, which leads to a greater yield.
When you need to water the currant in the spring with boiling water?
Watering the bushes in the fall will not bring the desired result, because at this time the kidneys on which the mites are settled are covered with a thick crust. Because of this, hot water will not reach the target, and the parasites will remain unscathed. Timing of currant processing boiling water in the spring is difficult, because the weather is different everywhere and the spring is unpredictable with its surprises. Watering the bushes is carried out when the kidneys are not yet swollen, but already responding to warming with a barely noticeable change in the color cover. It may even be when the snow is not all gone. The approximate timeframe is mid-March-early April.
How to treat the currant from pests in spring with boiling water?
Before the spring to shed currant bushes with boiling water, you need to cover their root system, if it is located close to the surface of the soil. For this, you can use sheets of plywood, boards, slate. It is most convenient to process the currant in spring with boiling water using a metal watering can with a sprayer on the spout. From the bucket irrationally watered - too much consumption of boiling water, and the plastic container can deform from hot water. Operating procedure:
- On a stove or a fire, water is brought to a boil, poured into a watering can and immediately begins treatment of plants. 100% boiling water scald shoots can not be, so they do not get burned. As a rule, with transfusion and in contact with the branches, the water cools down to +70 - 80 ° C. A lower degree will not give the desired effect. Such conditions are ideal for not damaging bushes and destroying pest larvae and fungal spores. To measure the temperature of the working fluid, it is better to use a thermometer.
- Branches are scalded evenly, nothing should be missed and not stay in one place. The distance from the shoots to the watering can should be about 10 cm. Not only the plants themselves are treated, but also the soil around them.
- To facilitate the procedure, shoots are recommended to tie at the top. Often 10 liters of boiling water is enough for the passage of three currant bushes.
- The bushes are treated at the same time, avoiding repetitions. Boiling water, killing parasites on shoots, quickly cools. When the treatment is repeated, the kidneys will be heated and the plant tissues may suffer.
- To increase the efficiency in water add a little potassium permanganate or salt. So you can not only destroy pathogens and parasitic larvae, but also disinfect the soil.
- To increase efficiency, many gardeners add copper sulphate to the boiling water (100 grams of crystals per standard bucket of water). Consumption for pouring shoots - 1.5 liters per bush. This inorganic copper sulfate compound is an excellent fungicide, antiseptic, insecticide and fertilizer.
- After treatment with hot water, pruning is carried out, old branches are removed and the beds are mulched .
Currant processing in spring with boiling water and soda
If you treat currants with boiling water with soda in the spring, you can get rid of not only the kidney mite, but also from powdery mildew. Spores of this fungus are carried by the wind and, settling on the branches, multiply. Then the tops of the bushes are covered with a white coating, as if they were sprinkled with flour. To prepare the solution, 50 grams of food or soda ash are added to the bucket of boiling water and the branches are sprayed as described above.
Currant processing in spring with boiled water with iodine
Pouring currant boiling water in the spring with the addition of iodine also helps to cope with the invasion of fungi on the plantation - powdery mildew, gray rot . Spores of these bacteria hibernate on the branches of the bush. For processing, you need to prepare a solution - pour 1 bottle of 5% iodine (10 ml) into the bucket of boiling water and shed the bushes from the crown to the bottom. In any working solution, you can add another 50 grams of laundry soap. It will help get rid of aphids, give the fluid a viscosity, and disinfectants can be on the surface of the branches for several days, and do not drain immediately from the shoots.
Treatment of currant bushes in spring with boiling water and urea
To combat pests, you can water the currant in spring with boiling water and urea . The treatment is done before budding, the spraying composition is 50 grams of urea (carbamide) per 10 liters of hot water. The solution perfectly copes with overwintering spores of scab, larvae and eggs of different parasites. Urea is added and as a fertilizer - the nitrogen in its composition in spring is useful for all plants.
Treatment of currant bushes in the spring with a hair dryer instead of boiling water
Deciding how to treat currants in early spring, you can use a conventional hair dryer. Powerful models of devices can give a temperature of + 120 ° C at the nozzle itself. Therefore, for thermal treatment of plants it is important to blow branches from a safe distance - 15-20 cm, not staying in one place for more than 5 seconds. In the maximum heating mode, a hair dryer at this distance produces hot air at a temperature of +70 - 80 ° C. This treatment is enough to destroy the larvae of parasites that have overwintered on the plant.
