The experience of successful cultivation will not come by itself, you will have to work long and hard, learning from your own mistakes. The vast majority of novice gardeners already in the second year of vine cultivation are faced with the question: when to open the grapes in spring?
When is it better to purchase seedlings?
The optimal time for buying young seedlingsMay is considered a time. Saplings in nurseries are already new, strong, unlike last year’s bushes, which are sold in April. Last year's planting material is not suitable for the beginning of the vineyard practice. A seedling that is well accustomed should have at least 7 true leaves.
When to open grapes in spring? Conditions of average daily temperatures
Теперь обратим внимание на кусты, укрытые на зиму since last season. Regions in our country are different weather conditions. Where the onset of spring there is no danger of frost, you can immediately remove the shelter. The vine is not afraid of frost, the cold is terrible only young buds. It is believed that if the average daily temperature does not fall below -5 degrees, it means that the period has already come when grapes should be opened in the spring.
Probable frost conditions
If you are engaged in viticulture in conditionsRegions prone to frequent spring frosts, including May frosts, should be guided by other rules of the disclosure of the vine. In order to avoid premature germination of the kidneys, we will first open the so-called ventilation in the shelter. To do this, make a few holes and wait for the green cone to appear on the vine. It turns out that the buds have sprouted in conditions as close to natural as possible, and the moment has already come when you can open grapes in spring in regions with a harsh climate.
We get rid of stagnant water
If small freezing temperatures do not harmthe state of the vine, the water accumulated at the base of the bushes, can cause serious damage to the sprouts in case of frost. If stagnant water is found in the rhizomes of a bush, even if it is insignificant, it signals that the time has come for decisive action. Armed with garden tools and scoop out the water, as well as break through the grooves for the runoff of water masses. It is in view of the extremely undesirable springtime stagnation of water at the head of the vine that it is recommended to plant seedlings on small hills.
We follow the weather forecast and take action
So, we figured out when to open grapesin the spring, and when it is impossible, and even follow the weather forecast for the coming days. What to do if the Hydrometeorological Center still promises critical freezing temperatures for the coming weekend? In the extreme case, a gardener should always have available remedies in the form of acrylic, agrofibre, hay or last year's foliage. Some gardeners, especially in case of unforeseen frosts, keep their own designed straw mats in a country house.
Artificial retention of budding eyes
Some skillful gardeners chatting with eachfriend on "When to open grapes in spring?", share useful experiences. That is how the trend of artificially arresting the growth of eyes appeared. We know that nothing threatens the vine in frost conditions, but young shoots that have just sprung from the buds are at risk of freezing. Therefore, immediately after opening, we first treat the vine with a solution of iron sulphate at the rate of 0.5 kg per 1 bucket of water. After spraying, the growth of young shoots will be delayed for at least a week.
Polarity method
After this time we will bind the vineto the trellis not horizontally (as usual), but vertically. When using this method, the perennial problem - when to open grapes in spring - will disappear by itself. Vertical tying of the vine is based on the polarity method. Buds will not be able to bloom at the same time. The first will be opened eyes at the tops. When it comes to the disclosure of the lower kidneys, the threat of frost by that time, as a rule, subsides. Thus, sacrificing to the frost part of the open shoots at the top of the vine, we save a significant part of the future harvest.
When to open grapes in spring? Check the condition of the kidneys
Even if the climatic conditions of your regionalmost perfect and late frosts can not threaten, you can even before the disclosure of the vine to check the condition of the buds on the bushes. To do this, usually dig one vine. Swollen shoots - this is not a reason for the full disclosure of the bushes. But shoots that started sprouting signal that the time has come when to open the grapes in spring.
Begin to "wake up" the roots
To wake up the plant did not die, wastingour forces on the upper shoots, we begin to warm the ground at the rhizome. To do this, we enclose the vine with black plastic wrap. Black material conducts heat well, and in conjunction with the greenhouse effect, this gives accelerated heating of the soil. You can also start shedding rhizomes with warm water. When the plant gets used, you can bring the water temperature to 40 degrees.
We hope that if you did not know until then when to open the grapes in the spring, our article gave you all the necessary useful information.
