How to pinch cucumbers?
Cucumber deservedly enjoys the love of the people. This vegetable has excellent taste, thanks to which it is used in cooking: it is pickled, and also used to prepare light snacks and salads. In addition, it contains a large number of substances and trace elements useful for human health, and is also able to have a cosmetic effect. It is not surprising that the cultivation of this crop is approached with all responsibility, not only in a professional, but also in an amateur environment.
Beds with lush green bushes or climbing vines of cucumbers can be found in almost any garden. This crop is great for growing in our climatic conditions, and therefore, even though cucumbers require the care and attention of a gardener, they have remained consistently popular for many decades. Moreover, with the right approach and in the case of planting the most suitable variety, even from a small plot or greenhouse, you can harvest a really large crop of this tasty and healthy vegetable. The only thing that can confuse a novice gardener who decides to plant this vegetable is the need to perform various care procedures, and we will talk about one of them below.
Why do you need stepchildren?
Many summer residents and gardeners strive to get a really plentiful harvest of such a tasty and healthy vegetable as a cucumber, for which they carry out a number of preparatory activities on the site. However, to achieve really impressive results is within the power of not only professional farmers, but also those who do not have much experience. Among the many procedures that can effectively affect the yield index, pinching (or pinching) bushes with cucumbers is considered one of the most important.
Even before you start pinching cucumbers, you need to study in detail why this event is needed at all. It should also be noted that many gardeners sincerely doubt whether it is necessary to stepson and pluck leaves and shoots from the bushes. Despite the fact that in some cases it is possible to harvest a good crop of vegetables even without pinching, it is still necessary to do it, since this is how fruit formation can be influenced. It is no secret that empty flowers are formed on the main stem of the cucumber bush during growth, that is, male plants that do not eventually produce fruits, and female flowers grow only on lateral shoots, and they are the key to high yields.
As you know, cucumber is a crop that biologists refer to the vine family, and therefore the process of growing it will be somewhat different compared to other vegetables. This plant begins to show its specific features already in the second week after germination - at this time the plant needs the first garter.But support is far from the only thing a bush needs for proper growth and development, since young shoots still need to be separated from each other and let them run along the ropes. If these events are not carried out, then it is unlikely that it will be possible to collect a large number of cucumbers from the garden.
The main stem of the cucumber, as you know, does not bear fruit, and therefore it is the lateral shoots of this plant that need special care. It is necessary not only to closely monitor the timely appearance of ovaries, but also to provide the bush with the optimal distribution of nutrients that it receives from the soil. During the period of the appearance of flowers, they receive most of the nutrients and trace elements. However, due to the fact that the central stem is the main one for the cucumber, during the period of active flowering, the side shoots will receive an extremely small amount of the nutrition they need. And this, in turn, will have a very bad effect not only on the yield, but also on the quality of the vegetables themselves.
Thus, the main purpose of pinching (or blinding) cucumbers is to remove a certain number of flowers from the bush so that the side shoots receive enough nutrition and the fruits can gain weight. An important point when carrying out pinching is the preservation of the green mass of the plant, since a large amount of nutrients is concentrated in the leaves.
Accordingly, if you correctly stepson cucumbers and remove unnecessary shoots:
- a large number of female shoots will appear;
- significantly increases the yield of the bush;
- the cucumbers themselves will not end up bitter.
It is important to pinch cucumbers, observing a number of certain rules and removing unnecessary flowers and shoots in time - then it will be possible to collect the maximum amount of delicious vegetables from the bush.
Thanks to the hard work of breeders, it is now possible to find varieties of cucumbers that simply do not need pinching. Such a plant does not form climbing vines, but grows in the form of a lush bush. First of all, we are talking about cucumbers of such varieties as "Sarovskiy" and "Petrovsky". There are also varieties with short side shoots - pinching them is also optional.
Timing
It is necessary to create a support for the cucumber liana fourteen days after the seedlings have been planted. After that, preparatory activities are carried out that precede blinding. So, the bush is neatly divided into a central stem and lateral processes, for which ordinary twine or any other similar material is used. It is important to strictly observe the timing of pinching and remove male flowers and extra leaves in time, because they do not bear fruit, but only take away nutrients and trace elements.
The optimal time to start the blinding procedure for each bush will be different. They begin to pinch cucumbers when the side shoots of the plant reach a length of at least five centimeters. In this case, pinching will be absolutely safe for cucumber vines, and the plant will not be damaged. If you perform this procedure when the size of the shoot is less than five or four centimeters, then you can cause significant damage to the plant by damaging the lash.If you start to cut off excess leaves and shoots when the lateral processes reach a length of fifteen to twenty centimeters, then this procedure will not bring the expected result.
Varieties of cucumbers that are pollinated by insects, and branched hybrids of these plants stepchild in such a way that several shoots remain at once. The best time to carry out this procedure with such plants is the appearance of the first five or six young leaves.
The final stage of pinching and pinching this culture begins approximately in mid-July. At this time, the bush is cut so that no more than two side lashes remain. In addition, during this period, it is necessary to engage in active pruning of the dried branches of the plant, as well as to remove its parts affected by any diseases or pests. The land under the cucumber bushes is treated with special means and herbal infusions, and various preparations and top dressings based on peat and wood ash are also introduced there. Already at the end of summer, when cool weather is observed at night, plants can be covered at night with plastic wrap. Such measures can significantly extend the fruiting period, since the shelter will protect the young shoots, which can then develop into a full-fledged lash that bears fruit.
Step-by-step instruction
Before proceeding with pinching, you need to study the features of different varieties of cucumbers. So, plants of self-pollinated and parthenocarpic types are characterized by the absence of the need for external pollination, and therefore such cucumbers form a lot of female flowers, and shoots grow extremely quickly.Thus, pinching such plants to get a bountiful harvest is not very rational. However, blinding and pinching are still used when growing such varieties, since this agrotechnical measure helps to effectively form a bush, regulate planting density and light levels.
Experienced farmers say that it is impossible to pinch a cucumber bush above the sixth leaf. This procedure in most cases is done up to about 3-4 nodes of the cucumber vine.
It is also generally accepted that for growing cucumbers in open ground and in a greenhouse, a completely different approach is needed, which, in turn, dictates its own specifics for pinching. So, today there is an active debate about whether blinding is necessary for cucumbers growing in a greenhouse. But even so, skeptics admit that if you eliminate unnecessary flowers and leaves, then the fruits will have much better taste.
At that moment, when the main stem of cucumbers begins to curl along the trellis, it must be pinched so that three or four leaves remain on it. You also need to remove the leaves curling around the trellis and securely tie the central trunk to the support. During the formation of additional shoots, they must be pulled out and blinded to a height of about half a meter. If this procedure is done in strict accordance with all the rules, then the plant will bring a large number of tasty fruits and will do this for a long time. However, it must be remembered that the correct formation of culture and the garter of a cucumber whip require a number of specific skills and knowledge that are acquired only with experience.
When growing cucumbers in open ground, the pinching technique will differ significantly, due to the difference in care between plants planted in a greenhouse or directly in the open. The need for this event for cucumbers in the garden is dictated primarily by planting density. But you do not need to pluck those bushes whose stems are not too long, because they will not take food from the shoots, and the yield will remain at a normal level.
It is mandatory to pluck the tops of unnecessary shoots from time to time. Trimming the tops of cucumber shoots begins when their length reaches at least one meter for the main stem and half a meter for side shoots. The plant during this period should already have secondary shoots (about twenty centimeters in length). On the main shoot, you need to destroy the ovary of the fourth leaf, and on the lateral stepson places after the second leaf.
A step-by-step instruction for pinching and blinding a cucumber bush in the open field will be a certain sequence of steps.
- First of all, you need to equip the supports, to which, as they grow, the lashes of the plant will be tied. At the same time, it is very important not to tighten the garter material too tight so that the plant can grow and develop freely.
- Even before the start of the preparatory procedures and before the installation of the trellis, you should take care of the optimal conditions for growing this crop. Regardless of the variety of cucumber, this plant is not planted too densely so that the shoots have enough space to develop.You also need to remember that in order to get a good harvest, the soil must be fertile, and its acidity is balanced for cucumbers.
- Accordingly, only at the next stage can one proceed directly to the active formation of plant lashes. At the same time, the top of the vine is pinched over the fifth or sixth leaf, and no more than three shoots are left for the bush itself. This technique is optimal for hybrid cucumbers, and for ordinary cucumbers, it is enough to leave only one stem, which will act as the main one.
- All subsequent procedures are pruning, care and pinching of the central cucumber shoot. Only four points of growth are left on it. Experts consider this number to be optimal for most varieties, and they will be able to actively produce good fruits for a long time. It is impossible to remove absolutely all the leaves from the liana, since the proper nutrition of the bush depends on them - only the most stunted and deformed leaves and processes are removed.
From the foregoing, we can conclude that with the conscientious observance of all points of the instructions, the pinching procedure can be successfully performed even by not the most experienced gardener. You can additionally consult with a professional farmer, especially in case of any difficulties. But if you properly care for the plant and blind the stepchildren in time, then getting a solid harvest of tasty and crispy fruits will not be difficult.
For insect pollinated varieties
The very name of this variety gives us a clear idea that it is only thanks to insects that fertilization occurs. Insect-pollinated varieties must be blinded, as male flowers form on the main stem of the plant.
There is a step-by-step diagram that will tell you how best to cope with this task.
- Even when planting cucumbers, do not thicken the beds, as this will then affect the quality and quantity of the crop.
- Choose fertile soil. Otherwise, cucumbers will need to be fed.
- Before starting the procedure, it is necessary to provide the beds with structures to which the grown loops will need to be tied. You need to tie the sheets so that they are in a free position, and this does not interfere with their further growth.
- It is better to tie up the plant thirteen days after planting the seedlings. It is necessary to tie up so as to clearly branch the central trunk and side processes.
- The initial stage of pinching is the formation of lashes. To do this, you need to cut off the lower leaves and cut off the tops on the main stem of the cucumber, which are located above the sixth leaf. This stimulates the growth of side shoots.
- You need to leave no more than three sprouts, the rest must be cut off.
- When shoots are formed, healthy leaves should be left on them.
Insect-pollinated cucumbers have a number of characteristic features that are inherent in these particular varieties. In such plants, the formation of ovaries and, accordingly, the formation of fruits for the most part occurs precisely on the lateral processes. This is because the central stem produces mostly male inflorescences that are unable to bear fruit, while female inflorescences appear in large numbers on shoots on the side.
Cucumbers that belong to these varieties begin branching quite late, and therefore experienced agronomists recommend stimulating the rapid formation of lateral vines.To do this, you need to blind first of all the main, central trunk, due to which it will consume much less nutrients and microelements necessary for growth, and the plant will begin to form lateral lashes and fruit ovaries much more actively.
For parthenocarpic
Parthenocarpic varieties of this crop do not require the intervention of insects for fertilization, as they are self-pollinating. As a result, female flowers grow predominantly on the cucumber of this variety. Compared to other species, these varieties of lashes and branches appear much faster.
Since female inflorescences are formed on the main stem, it is impossible to pinch the plant over the fifth or sixth leaf - it is necessary to remove the first four leaves in the axils. And at the same time, you need to cut both the leaves and the flowers. The fifth lateral stem must be shortened to twenty centimeters in length, and the top pinned.
Then leave the sprouts forty centimeters high, and above - fifty centimeters. The main shoot can be fixed only when it grows one meter from the ground, and only then pinched.
In the axils of the next five leaves, it is required to leave lateral processes, after which they must be pinned in the area above the leaves. When the central stem acquires a size of more than one and a half meters, then you need to pin the antennae over the third and fourth leaf. In this case, the secondary shoots growing below should be completely cut off, and then pinned in the area above the third leaf.
Tips for beginner gardeners
Garden owners with extensive experience in growing cucumbers and other crops recommend pinching off not only male flowers, but also the first ovaries, where fruits have already begun to form. At first glance, such advice may seem at least contradictory, but it has quite rational grounds. This is done because the next fruits will begin to form in a period of one to two weeks. It is also known that the first cucumbers taken from the bush do not have the best taste and visual characteristics.
In order for the bushes planted in a greenhouse or greenhouse not to give leaves, but tasty and beautiful fruits, it is recommended to eliminate each shoot up to the fifth leaf in such a way that one main stem is formed. Such measures help the plant develop powerful roots and use the maximum amount of energy for active fruiting. Often, gardeners do pinching not on a regular basis, but only once, removing only the first ovaries. However, this approach is rather controversial due to the fact that it is impossible to say whether it has any advantageous aspects compared to traditional constant pinching.
For those summer residents who do not have time to constantly cut off leaves, pinch shoots and form a bush on a regular basis, it would be a good idea to plant hybrid weakly branched varieties or single-stemmed plants. Also, such cucumbers show good results when grown in small greenhouses and greenhouses. If you plan to plant on a large area of land, it would be best to opt for the traditional varieties of this crop.
If the cultivation of cucumbers will be carried out in greenhouse conditions and the gardener is ready to regularly carry out blinding and carefully form a bush, then it will be optimal to plant varieties that bear fruit from the first months of summer until the first frosts appear.
The most suitable tool for pinching and blinding is small scissors with sharpened blades. It is strictly forbidden to simply tear off unnecessary parts of the plant. For planting, it is best to buy only proven varieties, since breeders are constantly breeding hybrids, the pinching pattern of which can be very different from the usual.
There are a few more tips that can greatly facilitate the life of a gardener. So, when pinching, it is necessary first of all to pay attention to pinching mustaches that the plant does not need, and promptly cut them off. Such formations actually only interfere with the bush and, rather, negatively affect its condition, as they consume quite a lot of micronutrients, and also further thicken the bush. This technique, among other things, contributes to a better recognition of the side lashes - they can be pinched in time.
There are also recommendations that will help the plant to more easily endure the stress inevitably associated with the stepping procedure. For example, in order to cause minimal damage to a cucumber bush when pinching, shoots and leaves should be cut strictly at the base, without touching all other parts of the plant. To do this correctly, it is necessary with the utmost care to move the sheet a little to the side and only then carefully cut off the process.Such caution is necessary, since the cucumber is a crop that is extremely susceptible to any damage, and in order to restore the damaged areas, the plant spends a fairly large amount of its forces.
Another good way to reduce the stress the plant receives after pinching is to use additional fertilizer. It is best to apply organic fertilizers or professional mineral-based preparations under the bushes. After that, it will be good to conduct another watering, which will help this vegetable restore water balance.
Professional agricultural technologists, when growing such a crop in open ground conditions, strongly recommend carrying out another procedure related to pinching - this is picking the root system of a bush, which will help to significantly increase the number of fruits obtained from the garden. To perform a pick, when planting seedlings in open ground, it is necessary to slightly pinch the roots of the plants, and the optimal time for this will be approximately the seventh day after emergence, that is, the period of formation of cotyledon leaves.
Despite the constant debate about whether it is necessary to pinch hybrid varieties in greenhouse conditions, it still needs to be done. Moreover, when growing this crop in a closed space, the removal of excess shoots and leaves is of particular importance, since excessive thickening of the bushes entails the rapid spread of fungal diseases, which can simply kill all the bushes. In addition, they will not receive enough light, which will cause the fruits to form incorrectly and be small and tasteless.
