How to pinch cucumbers in the open field
Every novice summer resident who grows cucumbers in his personal plot dreams of collecting a rich harvest, but not everyone succeeds. To obtain a generous harvest, you must follow the basic rules for caring for a cucumber crop, pinch and shape the vegetable bushes correctly.
Cucumber care steps
Step-by-step care for cucumbers consists not only in watering and feeding, but also in pruning, pinching and pinching.
Pruning is needed for intensive fruit growth and an increase in the term of fruiting. Stepping is necessary if well-developed lashes do not bring long-awaited zelents... Pinching - for the formation of side shoots.
Cucumber pruning rules
Pruning is done depending on the variety and on the method of pollination. Parthenocarpic varieties from seedlings should be grown in one stem, since a third of the crop grows on it, subsequent greens are formed on additional vines.
Brightening pruning is also performed.
An adult plant has a growth point should always be lit... When the bush grows to the very top, it cannot be redirected to a horizontal position. Since the whips growing in the horizontal plane do not transmit light, and the formation of fruits is reduced.
Cucumber pruning is carried out by any disinfected secateurs.
Do not remove, tear off leaves and stepsons with your hands. For this purpose, a sharp instrument is used to avoid damaging the plant.
Pruning is done for a generous and high-quality harvest... This procedure reduces the growth of the green mass of the plant and directs all the nutrients for the formation and growth of fruits.
How to prune cucumbers correctly
- To increase the flow of air to the plant, the lower leaves, flowers and stepchildren are pruned. This will keep the cucumbers from root rot disease, and prevent overgrowth of the plant.
- At 100 cm in height, in the area of 4 knots, 1 leaf and 1 fruit are left on the lateral stems, and the top is cut off.
- The third is at a height of 150 cm. In three to four nodes, two leaves and two fruits are left.
- The fourth zone is the last stage when the plant reaches acceptable growth. Leave 3 fruits and three leaves.
Lateral shoots are cut in a checkerboard pattern.
When the plant grows to the very top, it is twisted several times around the horizontal trellis and after the third leaf the growth point is cut out.
All foliage below the fruit must be trimmed.
The pickling of cucumbers makes it possible to grow a crop several times larger than usual.
Why is it necessary
Stepson the plant in the event that the developed lash does not bear fruit. Stepchildren form in the axils of the foliage and take nutrients from the plant, which leads to a reduction in the formation of ovaries.
Every 40 cm extra shoots, take away 1.5 kg of crop.
Greenhouse pinching methods
It is very important, in order to obtain a generous harvest in a polycarbonate greenhouse, to remove stepchildren from cucumbers, which are also grown under a film cover.
The limited space makes the pinching process the most important:
- The appearance of lateral stepchildren shades the plant and prevents air from reaching the roots
- It is necessary to cut the side shoots when their length reaches 3cm long
- The first pinching is done after the formation of 3 sheets
- All side vines are removed except for one strong
- During growth, they form the two most powerful side shoots
- The pinching procedure is carried out very carefully, step by step, since the cucumber spends a lot of time treating the wounds received
Stepsons must be removed before they become coarse and outgrowth.
4 stages and a scheme for pinching cucumbers:
- Stepson starts to carry out after growing 3-4 leaves... It is necessary to remove all shoots growing from the leaf axils.
- When appear 5-7 sheets, stage 2 begins. All excess is cut out, leaving one sheet and one ovary on each side.
- The third stage comes after the formation 8 sheets.
- When the appearance 11 sheets, the tip is pinched, and it begins to grow in breadth.
Bush varieties of cucumbers do not need pinching, since they do not grow lateral lashes. Varieties with a predominantly female flowering type also do not require pinching. This procedure will only harm the plant.
Pinching cucumbers is the most important procedure for caring for cucumbers, since not only the health of the plant depends on it, but also the quality and quantity of the crop.
Why do you pinch cucumbers?
Correct pinching makes it possible to grow a rich harvest. This procedure redirects the growth of the plant in breadth
The pinching of the main stem is carried out for the formation of additional shoots, since barren flowers mostly bloom on the main stem, and female flowers grow on the lateral shoots, which in turn form greens.
Pinching schemes in the greenhouse and outdoors
When grown under film
The rules for pinching in the greenhouse and open field depend on the variety or hybrid of the plant. The greenhouse culture is grown in one stem, making the pinching of the side shoots for 2 cucumbers.
This procedure is carried out with highly spreading varieties, such as: Rodnichok, Moscow greenhouse F1, Topolek F1, etc.
The varieties low branching, this procedure is done very carefully. These hybrids include: Gribovchank F1, April F1, Zazulya F1.
If you do not pinch, then due to the growth of a large amount of greenery, the plants will not receive sufficient lighting, which leads to the appearance of diseases and affects the quality and quantity of the crop.
Due to the large amount of excess greenery, caring for cucumbers becomes difficult and of poor quality.
- The first pinching of cucumbers begins at a height 50 cm.
- The second - from half a meter to a meter... Pinch the lateral shoots located above the first leaf, keeping one ovary.
- Third - upon reaching 170 cm... The pinching is done over the second leaf, leaving only 2 ovaries.
- Fourth - when the plant reaches two-meter growth. On the third leaf, 3 ovaries are left.
- The last pinching is done when the cucumber plant reaches the allowable height, leaving 3 leaves.
Pinching principle: one leaf, one ovary. Forming vines from the upper leaves, pinch at a meter height.
In the open field
The pinching of the main stem is carried out at the level 4-5 leaves in mid and late ripening varieties. This allows the rapid growth of additional shoots with female flowers.
In early maturing varieties, female flowers form on the main stem and therefore do not pinch.
By pinching, blinding, pruning and pinching, you can get a rich harvest, even from one bush. Delicious and aromatic greens will delight you with their crunch throughout the summer and winter periods.
How to pinch cucumbers correctly: the need for a procedure, how to do it right
Pinching cucumbers is one of the steps in caring for this vegetable. The procedure is done when cultivating plants in a garden bed on the street or in a greenhouse, regardless of whether there are problems with fruiting. The process itself is not complicated, but there are a number of rules that must be followed, if not observed, you can harm and even destroy the bush.
Why do you need to pinch cucumbers
Pinching cucumbers is necessary to obtain a high-quality harvest. On the main shoot of cucumbers, male inflorescences and branches are usually formed, which are barren flowers, and female shoots are necessary for abundant fruiting.
Female shoots develop only on the sides of the main bush, so you need to know how to pinch cucumbers and how the bush is formed. Pinching cucumbers involves preserving the leaves, since the deciduous mass contains positive trace elements, which they subsequently send to ripening fruits.
Pinching cucumbers has significant positive aspects, including:
- increasing the education of female inflorescences
- elimination of bitterness from vegetables
- increased productivity.
This procedure significantly improves the quality of fruiting, improves the palatability of the fruit. With the help of the procedure, it is possible to significantly improve a bountiful and high-quality crop even from one unit.
For beginners in the field of pinching cucumbers, experienced gardeners give several important tips to help prevent bad situations:
- When forming a bush, you need to remember to loosen the soil.
- In the process of tying, take into account that the vegetable has a weak root system. The work requires careful execution, without damaging the roots.
- When working with a bush, take into account that the main stem is fragile. Manipulation must be done very carefully.
- Remove male flowers and unnecessary sprouts in time.
- Yellowed dried leaves and damaged tendrils are not cut off, but cut with scissors.
- Cucumbers are taken care of regularly. You need to take care with the help of exceptionally clean tools, avoiding contamination of the culture.
- During cultivation and harvesting, it is not recommended to swap the top of the bushes. This can cause death or yellowing.
- After cutting the leaves, there should be no hemp left. Otherwise, on bush cucumbers, the plant will be struck by powdery mildew, which will prevent the ovaries from forming correctly.
How to pinch cucumbers correctly?
The above scheme is effective for many varieties, not counting hybrid ones. Here, flower stalks are able to be located on the central stem too. As a result, it is not entirely clear what to delete. Just mindlessly walking over it, cleaning everything off, will not work. With the active spread of hybrids, when each agronomist has 1-2 such specimens, it is necessary to additionally look for information describing the features of working with them.
One might even decide that since the "female" flowers are already formed on the main stem, they do not need to be eliminated. But this is a delusion. Plucking is also needed for hybrid varieties. Netherflowers will still appear, but already on the branches. For most of them, separate pinching patterns are studied.
The general algorithm is to destroy the growth points of new lateral shoots. If you leave them, they will turn the cucumber into an overgrown, but practically unproductive bush. From the point of view of decor - good, in terms of getting real benefits from the plant - not very much. This is done after 5-6 sheets. At the time of fruiting, several fairly short lateral shoots should depart from the central stem, where ovaries will begin to appear. Of course, if it is not a hybrid with a different structure.
This step does not end the blinding procedure (another name for pinching). Additionally, stepchildren should be eliminated at the junctions of the leaves (sinuses). They, too, will pull in all the nutrients, depleting those areas that really need it. And in the lower part, the lateral shoots are completely eliminated, without preserving 1 or 2.
In the greenhouse
Working with greenhouse plants is somewhat different from what is done with crops in the open field. They are usually formed earlier and carried out in a different way. Here the scheme of elimination of "empty" flowers on the central stem will act in order to stimulate growth on the lateral ones.
In all varieties pollinated by bees, the pinching is done over 6 leaves and most often affects the next 8 sinuses (70-80 cm of the stem). Among hybrids, this applies to the parthenocarpic category. Especially the one that boasts large, long fruits. Everything is removed except the leaves and already formed lateral branches. Those that are in their infancy, as well as antennae and flowers, are destroyed.
Up to 6-7 sheets from the bottom, only stepsons need to be removed. The further system for 8 sinuses can be carried out as follows:
- Shoots trying to form are removed while preserving the leaf and fruit in the amount of 1 piece.
- After overcoming the border of 1 m in height, the length of the lateral stems can be 40-50 cm.
- Many agronomists pinch the top of the head, allowing the main shoot to grow to the crossbar to which its rope is attached, and the further height is "blinded".
With most hybrids, the scheme is slightly modified.
- Visually, the plant is divided into 4 parts in length, after which a separate work is done with each part.
- At the very bottom, all the rudiments in the axils are removed at the level of 4 leaves.
- The next 4 nodes (new zone) are deprived of lateral shoots up to 1-2 leaves and 1 fruit (ovary).
- Slightly higher on the same area there are already 2 fruits and the same 1-2 leaves.
- The last part, including the crown, can keep up to 3 fruits and 3 leaves on the shoot. At the top, the growth point is pinched when 2 cucumbers and 4 leaves appear on it.
- The main stem should slightly outgrow the trellis to catch on with 1-2 turns.
In the open field
In the open field, the process of "blinding" depends on how climbing varieties are planted. For short ones, pinching is not required, since it will not have an effect on productivity as such. But with long ones, work is required.
The first step is to eliminate the top. It is produced only after the plant reaches a height of 1-1.2 m. The lateral processes need to be 40-50 cm each and have 2 orders of magnitude shoots on themselves. Their length should no longer exceed 20 cm. Only with such indicators will it be possible to preserve the productivity of the bush.
If a cucumber grows in a garden without a garter, the algorithm for working with it is very simple. On the main stem, after 4 leaves, the point of growth is destroyed, on the lateral ones - after 2. If the variety to be worked with is a hybrid one, "blinding" is performed only with lateral shoots. All axillary shoots located on the lashes must be pinched.
Why do you need
Pinching cucumbers is a method that allows you to increase the yield of cucumbers, regardless of the crop being grown. Its essence boils down to removing barren flowers - male flowers that do not give an ovary, and stimulating the growth of lateral shoots. Read about pinching tomatoes in this material.
The benefits of pinching are due to the following factors.
- Barren flowers appear mainly on the main stem, while female flowers form on lateral shoots. It is very simple to distinguish them: male flowers grow in groups, bloom on short legs. Women, as a rule, appear one by one, and at their base is an ovary - a small cucumber. The main task of the gardener is to stimulate branching: the more side shoots, the more female flowers appear. For this, pinching of the main stem is carried out.
There are new varieties of cucumbers in which the female flowers bloom on the main stem. But even in this case, you need to get rid of the excess of barren flowers.
- Pinching also affects the taste of the fruit. Although male flowers do not interfere with the development of female flowers, they require watering and nourishment. Accordingly, the more of them remain, the less nutrition the ovaries receive. As a result, ripe cucumbers often have a bitter taste, especially the rind. It is recommended to remove up to 80% of the barren flowers in order to ensure an excellent taste for future cucumbers.
- The formation of the bush itself does not affect the yield, but it greatly facilitates the care of the plant. Pinching allows you to get rid of excess green mass, which is especially important for a greenhouse, ensures the efficiency of watering and feeding, and most importantly, guarantees a sufficient amount of light, which is important for such a light-loving plant.
Pinching is necessary when growing crops in a greenhouse.Outdoors and with some modern hybrids, this procedure can be dispensed with. In fact, everything is determined by the characteristics of plant growth.
Important tips for correct pinching
Every summer resident knows how to pinch cucumbers, but there are situations when, in the process of forming a bush, situations occur that require help. For those who have just started getting to know the garden, it is important to study all the information in detail in order to avoid unpleasant situations:
- In the process of tying cucumbers, it is worth remembering about the weak root system of the plant. The procedure should be performed carefully without harming the roots.
- During the formation of the bush, do not forget about loosening the soil around the plant.
- It is worth carefully ensuring that male inflorescences and unnecessary sprouts are removed in time.
- When working with a bush, it is worth remembering not only about the fragile root system, but also the fragility of the main stem. Perform all manipulations very carefully.
- Damaged antennae or dry yellowed leaves should not be torn off, but carefully cut with scissors.
- When caring for cucumbers, it is necessary to use only clean tools for pruning in order to prevent infection of the plant.
- During harvest time, it is undesirable to swap the tops of the bushes. This often provokes yellowing and death of the plant.
- You should be careful with the stumps after cutting the leaves. They cannot be left, otherwise the plant is affected by powdery mildew, which will not allow the plant to form the ovaries correctly.
The procedure for pinching cucumbers is quite complicated, but very effective. If done correctly, you can end up with a bountiful harvest of sweet cucumbers without bitterness.
