Currant - spring care, tips of seasoned gardeners
The number of pests and diseases can be easily reduced by planning cultural care activities throughout the year. The treatment of the currant in the spring begins with the examination of the bush. It is necessary to eliminate dry and diseased branches. Scraps burn - they are a beneficial environment for parasites. The ground under the bushes is advised to be sprinkled with ashes and digged - this will damage the nests and concentrations of spores and larvae. After the soil, sprinkle with humus, which will serve as a bush for the whole summer. Then you can plan the treatment of currant in spring from diseases and pests.
How to treat the currant in the spring?
Deciding what to spray the currant in the spring from diseases and pests, many resort to the help of chemicals. At the same time, it is necessary to observe clearly irrigation terms, because the currant vegetation starts very early, and changes occur very quickly. To conduct similar procedures it is necessary before bud opening. They make a manipulation in the early spring, when the kidneys just begin to peck and have not yet formed buds. The treatment is done in warm weather at a temperature of + 5 ° C.
Currant processing in spring with copper sulfate
For spring processing, copper sulfate is actual. Since there are no leaves on the branches and buds are not pierced, it immediately destroys the larvae of pests - mites, aphids, fungal infection. In addition, they can further disinfect and coarse the soil around the bush. The treatment of currants with copper sulphate in spring is carried out in a strong concentration, as the plant has no leaves, and the bark is able to withstand the effect of the drug that eliminates parasites.
The norm of copper sulfate is 100 grams per 1 bucket of water, for a greater effect, 25 grams of laundry soap is added to the solution. To prepare the mixture, the preparation is first poured with a small amount of hot water, since in a cool one it is poorly diluted and then diluted to the required volume. The obtained solution is generously lubricated by the branches of the plant and irrigates the soil around the bush. The deadline for completion of the procedure is the end of March and the beginning of April.
Currant processing in spring with ferrous vitriol
Not only for spring sprinkling, but also for preparation of the garden for wintering, iron sulphate is actual. It is an excellent substance for getting rid of diseases, fungi, scab, lichens, fruit rot, is relevant for the prevention of chlorosis. Treatment of currants with ferrous vitriol in spring - the right proportions:
- Against dangerous insects (including wintering under the bark) - 500 g per 10 liters of water. Shrubs irrigate generously before the opening of the kidneys, the second time - in November.
- To combat fungal diseases apply a weaker solution of iron vitriol - 30 g of ingredient per 10 liters of water. Spraying is done 2-3 times every 5-7 days.
- To overcome the disease of chlorosis (lack of iron in the soil), 50 g of the drug is diluted in 10 liters of water. Irrigation is carried out every 4-5 days before the revival of the green color of the foliage.
Currant processing in spring Bordeaux liquid
Traditionally, the treatment of the currant in the spring from diseases and pests by the Bordeaux mixture is made later, at the beginning of the opening of the kidneys. It saves the culture from scab and leaf blotch, anthracnose, rust, septoriosis. The saturation of the solution depends on the stage of development of the crop:
- Before pecking the kidneys, an intensified 3% mixture - 300 g of lime and 300 g of dry copper sulfate are taken per 10 l of water. The rate of consumption of the mixture is 0.5-1 liters per bush. It is not recommended to irrigate the Bordeaux liquid in a cool period or during a prolonged rain. For processing, use a freshly prepared mixture.
- The second treatment of currant Bordeaux liquid is planned at the bud formation stage, but before they are opened with a 1% solution: 10 liters of water per 100 g of lime and copper sulfate.
- 15 days after harvesting, one more irrigation should be carried out with a 1% Bordeaux mixture.
Currant processing in spring with urea
Carbamide ( urea ) is a nitrogen fertilizer with 46% nitrogen content. The treatment with this drug hives solves several problems - it helps to fight the mass of pests and diseases and enriches the soil with nitrogen, which is necessary for the plant to grow green mass and form a more weighty crop. How to conduct the procedure:
- Primary irrigation is performed prior to the formation of the kidneys. The solution is prepared in a ratio of 500-700 g urea to 10 liters of water. At 10 m 2 area takes 2.5 liters of working fluid.
- Especially effective is the treatment of currants with urea in conjunction with copper sulfate - 700 g of carbamide and 50 g of vitriol per 10 liters of water.
- In the case of nitrogen starvation, if the leaves turn yellow on the plant, a weak blooming can be carried out another irrigation.
Currant processing in spring folk remedies
If in the fight against pests do not want to use chemicals, then it is appropriate to process currants with folk remedies. From any diseases and insects you can spray the bushes with different compounds. Tincture of garlic, wormwood, tobacco, onion husks proved to be good.

- The roots of the bushes are covered with tarpaulins or plywood. For work it is better to use a metal watering can with a strainer.
- Water is brought to a boil, poured into a container and immediately scalded uniformly with each branch in the bush from a height of 15-20 cm. As the boiling water reaches the bark, its temperature will drop to +60 - 70 ° C and it will not damage the plant.
- One to one bush consumes 1-1.2 liters of hot water.
- To increase the effect, salt, iodine, manganese or copper sulfate are added to the solution.
Currant processing in spring with ammonia
A solution of ammonia or ammonia in its composition has about 82% nitrogen, helps to fertilize the culture. At the local level, it acts irritatingly and is capable of destroying aphids and ticks. The dosage of the drug is not harmful to humans, and the parasite leads to respiratory paralysis. To prepare the solution, take 10 liters of water, 40 ml of the preparation and 40 g of soap. The last ingredient serves to enhance the sticking effect.

For the prevention and protection against insects processing of currant bushes from pests and diseases with a soap solution is made before and after budding.
Currant processing with blowtorch
In the fight against the kidney mite, powdery mildew, aphids and their larvae, the heat treatment method, which involves burning open currant branches with open fire, is relevant. The work should be carried out in the spring until the kidneys swell (in early March), sometimes at this time under the bushes there is still snow. In this procedure, it is important not to be late, otherwise the eyes may die.
The currant is treated with fire using a blowtorch or a gas burner. In this case, each twig and the soil near the bush is quickly burned with flame. Fire is sent to the shoots at a distance of 8-10 cm and is carried along the trunk 2-3 times, as if with stroking. Bring the flame close to the branches and long stay in one place can not. Work should be calm and confident, the main thing is not to overdo it and not damage the kidneys. In this procedure, aphid eggs and most mites wintering in the kidneys die.
