How to pinch cucumbers in a greenhouse?

"Stepson" - secondary, almost equivalent processes that grew out of the corner on the main lash, also bearing fruit later. But their removal is necessary, since cucumbers from them taste more bitter from the ends, of a smaller size.

Removing "stepsons" is mandatory... The pickling of cucumber plants is carried out in any greenhouse - it doesn't matter what its walls are built of: foil or polycarbonate. The main thing is that it let in slightly scattered sunlight - this is its purpose. And so that the cucumber shoots contribute to the growth of the main shoot, like a grape bush of climbing varieties, they are stepson. This measure will also be needed to prevent the development of diseases caused by all kinds of pests and a general weakening of vegetation.

With the growth of a cucumber bush (or liana, as it is sometimes called), the main lash originates from the root. It accounts for the main harvest. In certain places, from some nodes, in addition to the main leaves, lateral shoots sprout, called "stepchildren". If you save them accidentally, they will give a cucumber "offspring", but the cucumbers from them will turn out to be much worse. The main principle works: the farther from the root, the less water and minerals get to the fruits, since the vine (or trunk) and the main branches are the main conductor of the nutrient medium obtained from the soil.

The interest is that from one "stepson" can grow a second one (daughter, stepson of the second order). In theory, they can grow indefinitely - at least a little. "Stepsons", like the branches of a tree, are capable of both branching and producing crops. And the farther from the main lash, the worse the quality of the crop will be, even in the presence of full watering, spraying from pests and (outside) root feeding, always done in a timely manner. All unnecessary growth must be removed - it will go to the compost, here it simply will not bring any benefit.

"Stepsons" take vitality - in every sense of this definition - from the main lash. The "wild" and overgrown cucumber bush consumes nutrients for the constant growth of new branches, not giving the owner a full-fledged crop. Removal of excess shoots is required not only for cucumbers, but also for all plants of the pumpkin family: one day there comes a moment when the growth of the shoots needs to be limited, since one root is not enough for such an "army" of cucumbers. The disadvantage of pinching is labor costs, but it will not be possible to do without labor investments at all: any culture requires timely care.

For the first time in the "cucumber" season, cucumbers are stepchild after the appearance of at least five leaves in the plants. The bush reaches a height of about 35 cm. "Stepsons" grow by an average of 5 cm. You cannot let them grow further - they will impoverish the main plant. These processes are cut off according to a specific situation, without looking at the lunar calendar. In general, pinching is not delayed until August.

The maximum number of sessions of this procedure is no more than 3. Removal of "stepchildren" is performed again in connection with the appearance of new processes of the same kind.

Removing the appendage leaves a few millimeters in length on the main stem from it. If you remove it "flush", then the main lash will suffer, i.e.Because 2-3 mm of tissues die off, and drying out of the cut site will damage the main stem.

It often turns out that pickling of cucumbers is done in May, June and July.... Remove "stepchildren" with a clerical blade or well-sharpened scissors. Correctly breaking off or cutting off the stepsons means not only to prevent damage to the stem, but also not to accidentally remove the main apex. When the bush turned out to be untied or there was no support for it to catch on, eliminate this defect. The best support option is a trellis structure; in the simplest case, a net or at least a fishing line can be stretched at several elevations above the ground.

Even those "stepchildren" on which there are already set fruits are subject to removal.... At a height of up to 40 cm in the first stage of the procedure, not a single lateral process should remain. This will allow the roots of the cucumber shoot to develop better: organic matter is not spent on absolutely unnecessary shoots. The reserve that the plant continues to receive from the soil will be needed for the main development of the whip with leaves. After the pinching session, the soil is loosened and watered under the root of the plant.

When the height of the bush approaches a meter, the cucumber vine will bloom. The lowest leaves of the plant - the first 3 - are removed, since there will be no use from them. Organic matter formed due to photosynthesis is produced in the required amount from the overlying leaves, then they flow to the lower and underground parts of the plant.

At the second stage of pinching - about a month later - the procedure for cutting off excess inflorescences is also performed.

The third stage consists in cutting out the stepchildren and extra inflorescences only after the next growth of the “tops” by 40 cm. The process of circumcision repeats the previous sessions. After the vine grows back by 120 cm, you can neither pinch nor remove excess flowers. At this stage, the harvest will be the largest. The overgrown lateral branches of the bush are lowered - having released the "mustache", they can catch on the ground with them and re-root.

With a decrease in the growth rate of the vine and the threat of a decrease in yield, the plants are fertilized, and also additionally sprayed with pests.

They mainly use the classical, pinching scheme with pinching the main branch, "Danish umbrella" and processing the main lash.

Pickling cucumbers according to the classical scheme is carried out according to the step-by-step instructions described below. A pruner or knife is chosen as a cutting tool.

1. Harvesting is carried out in the morning or after sunset, at low air temperatures.

2. You only need to cut off the extra lateral branches, as well as the shoots that form below the first pair of leaves.

3. The bushes should be thinned once a season to get abundant fruiting.

You shouldn't get carried away with stepchildren. This method is called "old-fashioned" - it has been known since the time when cucumbers became widespread as a table (edible for humans) culture, and varieties that were most resistant to cold weather were bred.

Pinching the main branch of cucumbers is performed according to the following scheme:

• from the moment when the fourth leaf appears on the main stem, and before the fourth inflorescence is formed on it, the tip is pinched;

• if possible, you can wait when all the cucumbers at the top of the stem are tied, and then hold two more pinches;

• as soon as a cucumber is tied on the brush, you need to pinch its top so that the plant directs all its forces to pouring and ripening the fruits.

Pinching - slowing down the growth of the cucumber vine... It is necessary to redirect nutrients - not for endless growing of branches and tops, but in order to accelerate the ripening of existing fruits. This is a method to avoid the appearance of a significant number of "blank flowers".

Plucking the main whip gives the cucumbers the following benefits:

• increases the number of female flowers on a bush pollinated by bees;

• releases side shoots;

• forms new side lashes, which will also have buds and fruits;

• by pinching, you can get cucumbers with shorter internodes, with a larger leaf area, which contributes to better illumination and airing of leaves and fruits.

The complexity of the work with pinching by the "Danish method" justifies itself by the simplified care of cucumbers: it is easier to process them from diseases and pests. Moreover, all cucumbers are higher, which is undoubtedly a significant plus. Remove lateral shoots and the accompanying "offspring" should be according to the scheme below:

• the main branch is pressed when the cucumber plants grow to the height of the 9th leaf;

• on the side shoots, several of the healthiest leaves are selected, the rest must be removed;

• the growth of lateral shoots is brought to 4 knots, and then pinched.

Cucumber bush, with 12 growing points, will give a good harvest. But there is another option for cutting off excess leaves and shoots - under the same definition.

1. Up to 5th sheet all lateral vegetation is removed.

2. Until the 9th - remove all elements, except for the number of fruits equal to the number of leaves.

3. Until the 13th - leave two fruits near each leaf.

4. At the 14th sheet leave one stepchild's shoot, cut off all the fruits. As it grows, this lateral shoot is pinched when it grows two leaves.

5. Until the 20th - leave a couple of "stepchildren", remove the fruits. The distance between the "stepchildren" is at least one sheet.

6. Near 20 sheet one lateral process is left. After growing to 8 leaves, it is pressed.

7. Main whip transferred through the trellis and pressed down after 3 sheets.

8. On the second sheet leave a side shoot, after growing 5 leaves, it is pressed down.

The easiest way is to remove all lateral processes. Only leaves remain on the main branch - with fruits set nearby. This method is suitable for self-pollinated cucumber varieties.

When pinching, you cannot use an insufficiently sharpened garden tool, for example: side cutters or pliers - neither one nor the other has sharp edges that can clearly and quickly cut off unnecessary growth. It is also undesirable to tear off the "stepsons" with your hands - by accidentally tearing off a part of the stem, you will simply ruin the plants.

It is better to carry out pickling immediately, at the first opportunity, when the lateral shoots have just become visible... It is impractical to remove lateral overgrowths: they are a full-fledged part of the vine, as, for example, is the case with grapes. But until they get thicker and harder, they are much easier to remove. But be prepared for them to appear in other nodes on the next or in the coming days. There is a risk of losing count, removing even those that were supposed for further growth: it is also undesirable to remove absolutely all stepchildren, since the plants will not grow to a height of more than a meter.

Having lost many lateral shoots and some unnecessary fruits, the bush will receive a "respite", but it will not last long: roots and preserved stems, leaves and fruits will go into rapid growth.This means that watering and feeding cannot be neglected - the opinion that the plant needs reduced care is deceptive. On the contrary, after circumcision, it receives a kind of stress, becomes more vulnerable to possible drought, pests and diseases - it is important not to let it wither during this period. Sanitary pruning - removing dead and diseased leaves - is also important.

The strong regrowth of the lateral shoot also depletes the plant, which has given it a significant share of the stored moisture and nutrients. If, during pinching, a certain shoot was missed and grew by 5 or more leaves, it is too late to cut it off - let it grow, but the next pinching should remove all second-order shoots that have grown on it and go beyond one of the above schemes.

There is no need to feel sorry for the extra shoots to be removed... If you give the cucumber plant complete freedom, then it will grow too many stems and leaves, most of which are useless. You are growing a fruit garden crop for use, and not decorative or wild for the sake of beauty, decoration of the site. The cucumber, like most plant species that produce edible fruits, wastes nutrients and water for branches in vain, from which there will be no use, except for coolness and purification of the air from carbon dioxide.

Don't let your cucumber care take its course - even in a greenhouse. Despite the fact that in greenhouse conditions weeds germinate several times less often than in the open part of the garden, cucumber beds must be weeded regularly.

If there is not enough natural light in the greenhouse on a gray and rainy day, turn on additional lighting. For example, LEDs are a great option.

It is impossible to swamp the soil in places where cucumbers grow. It should be wet and not impassable dirt. When this condition is violated, the roots simply rot from a lack of oxygen - they also breathe through the fertile layer in which they continue to grow. A few hours before watering or rain, the soil must be dug up - the water will easily seep into it and reach the lowest roots faster. The formation of a crust on the surface of the soil is unacceptable.

If all the conditions for pinching cucumbers are met and timely and proper care is carried out for the vines, then the harvest will not be long in coming. The quantity and quality of fruits are on average proportional to adequate measures and methods of caring for cucumber plants.
