Every grape grower knows that you can get a good harvest only from a he althy bush. It requires regular care, which includes not only spraying with fertilizers in early spring, but also treating the plant with iron sulfate in autumn, as well as cutting and covering branches.
Why process grapes before wintering
Over the summer, a large number of various diseases can form on the branches. Autumn processing of grape bushes from pests and diseases prepares them for the winter period. If this is not done, it will be difficult to cure a weakened plant in the spring. Due to parasites, the leaves of the vine will die, which will have a bad effect on the future crop and may lead to the death of the entire bush.
Spring treatment helps the plant feel good and bear fruit all summer. But it is worth remembering that in winter the grape bush needs nutrients and vitamins even more so thatsurvive the cold period and build up reserves of strength for spring.
How grapes are processed in autumn from diseases
To rid the grape bush of diseases and small parasites, the surface of each vine is sprayed. The solution for this can be prepared from different preparations, but more often gardeners use vitriol. Copper and iron vitriol do an excellent job of disinfecting branches, kill fungus and mold, and also have an acaricidal effect (destroy mites and other harmful insects).
Some spray a vineyard with a solution of diesel fuel. Half a liter of diesel fuel is mixed in 10 liters of water, then branches are processed with this mixture. This should be done after all the leaves fall off so that burns do not appear.
Processing grapes with iron sulfate
Iron vitriol is a microfertilizer that is widely used for processing fruit trees. Consists of green granular crystals, for which it is often called green vitriol.
You can start processing the grape bush immediately after the loss of leaves. On a bucket of water with a volume of 15 liters, 0.5 kg of iron sulfate is taken. It is necessary to dilute until the granules are completely dissolved, after which spraying can begin. Despite the fact that the substance is characterized by a rapid oxidative reaction and is considered harmless to the human body, it is still recommended to wear gloves and protect the respiratory organs.
If your garden is no longer young, ferrous sulfate treatment of grapes in autumn is very important. The solution perfectly fights lichens, cytosporosis, moss, black cancer and scab, and also relieves branches of harmful insects and larvae. To destroy various types of fungi, iron sulfate is added to the whitewash, which covers the trunks of the bush.
Sprinkling with iron sulphate eliminates iron deficiency. Regular processing, carried out in autumn and spring, allows the bark to become more elastic, and the leaves - larger. As a result of this, more new shoots grow, which leads to an increase in the number of fruits. The berries are getting bigger and he althier.
It is worth noting that iron sulfate should not be mixed with slaked lime. Such solutions are prepared, as a rule, using copper sulfate.
Copper sulfate for garden spray
Copper sulfate is called copper sulfate, consisting of light blue crystalline formations. It is used for preserving and feeding trees. Excellent fights against any kind of parasites and diseases.
Processing grapes in autumn with iron sulfate is carried out from the second half of October, when the leaf fall ends. Approximately 0.1 kg of copper sulfate is diluted in 10 liters of water and stirred until the granules are dissolved. After that, the whole bush is sprayed with the mixture. On average, one plant takes about 2 liters of solution. You need to work in gloves, a gauze bandage, glasses and waterproof clothes.
Destroy grape aphids and variousfungal diseases are capable of Bordeaux liquid, which can be bought in powder form or prepared independently. Make a mixture of freshly slaked lime, copper sulfate and water. It is important to observe the necessary proportions so as not to harm the plant. Apply this solution in the same way as iron and copper sulfate - for processing grapes in autumn or spring.
Preparation of Bordeaux liquid
In horticulture, 1% or 3% Bordeaux mixture solutions are used. For a 1% solution, 0.1 kg of copper sulfate, 0.1 kg of slaked lime and 10 liters of water are taken. It is advisable to use rain water. Vitriol and lime are bred separately from each other. After that, the vitriol solution should be poured into liquid lime in a thin stream and mixed. In order not to burn the bush, you should check the resulting mixture by dipping an iron object into it. It should not have a red coating. If it appears, add more lime.
The technology for preparing 3% Bordeaux liquid is identical to the first two. Only for the same amount of water you need to take 0.4 kg of slaked lime and 0.3 kg of copper sulfate.
When to start autumn processing of grapes
Classic processing of grapes in autumn is done after the last berry harvest. It is combined with cutting and sheltering branches. The young vine is not suitable for wintering, so all unripe branches must be removed. They will still die during frosts, causing great damage to the plant, consuming nutrient reserves.substances.
In addition, fresh shoots are more susceptible to diseases that can be transmitted throughout the bush during the winter shelter. Pruning of young branches is a very important step in preparing the plant for wintering, after which the processing of grapes with iron vitriol begins in the fall.
Pruning grapes before shelter
Remove fresh shoots of grape bushes should be a little time after the last harvest. If new branches are cut immediately, the plant can weaken and lose a significant part of the nutrients that were used to develop the young vine.
It is best to prune with the arrival of the first cold weather or immediately after the loss of leaves. During this period, all useful substances begin to collect in the root system, which guarantees their safety.
Having removed the young shoots, you should carefully look at the rest. The processing of grapes in autumn with iron sulfate should be carried out after cutting off all branches that are not sent for wintering. This also includes those vines that have any type of disease.
If you pay due attention to the processing of the shrub and carry it out correctly, the grapes will delight you with a rich and he althy harvest every year.
