Growing cucumbers in a polycarbonate greenhouse: soil preparation, planting scheme and features. How to plant cucumbers in a greenhouse to get a harvest all year round How to sow cucumbers in a greenhouse

08.10.2023

Among vegetables, cucumbers are the most popular. They are grown in all household plots. They begin to bear fruit early, especially if the plants were planted in a polycarbonate greenhouse. The material is able to retain heat for a long time, vegetables receive a sufficient amount of light, and thanks to the plastic coating, the leaves do not get burned. Plant care is minimal, the main thing is not to forget to feed them additionally.

In polycarbonate greenhouses, cucumbers receive enough natural light

Despite the fact that cucumbers love warmth, they also need ventilation. Therefore, in a greenhouse made of polycarbonate, there must be windows that allow the room to be ventilated. Thanks to this, the optimal temperature for growing seedlings prevails inside the greenhouse.

It should be noted that such a structure is a strong and reliable structure. Their preparation in the spring is reduced to a minimum: check the tightness of the connecting seams and wipe the plastic from plaque accumulated over the winter.

Preparatory work

It is better to plant cucumbers as seedlings. Planting seeds should be done in special paper or peat pots, so the plants do not have to endure replanting, and peat provides additional nutrition for the seeds. Such containers are buried in the soil along with the seedlings. In a polycarbonate greenhouse, seeds can be sown directly into the ground. The choice of planting method depends on the type of seed. For greenhouses, it is better to choose self-pollinating hybrids so that you do not have to do pollination yourself in the future.

Today, breeders have developed many hybrid varieties that are endowed with such positive qualities as:

high yields;
seeds are treated with disinfectants;
vaccinated against various diseases;
unpretentious;
do not require special care.

Among the varieties that give good yield are: Marinda, Caprice, Halli. Preference should be given to species that have undergone zoning, i.e. they are adapted for growing fruits specifically in your region. Many species are developed for cultivation in the northern regions and the Urals, where the prevailing temperature is not entirely suitable for the growth of cucumbers.

Marinda cucumber is a popular variety for growing in a greenhouse.

Arrangement of beds

Since plants love warmth, especially their root system, it makes sense to make “warm” beds by using compost (any organic material will do: sawdust, leaves, etc.) or manure. To do this, a layer of soil is removed, fertilizer is placed at the bottom and covered with a 25-centimeter layer of soil. To grow a good harvest, the cucumber planting scheme in the greenhouse must be correctly planned: there should be only four seeds per square meter. Therefore, distance must be maintained.

To increase the temperature, you can create an additional greenhouse on the greenhouse bed. To do this, arcs are installed and polyethylene film is stretched over them. Thanks to this approach, the seeds will hatch faster.

Planting seedlings in beds

Many summer residents prefer seedlings rather than seeds. When using this method, the crop grows slightly faster. Before transplanting, the bushes should have at least 4-5 leaves. If there are “warm” beds, cucumber seedlings are planted in a polycarbonate greenhouse in early April; if there is none, not earlier than mid-May. It needs to be planted correctly, taking into account the distance, otherwise the bushes will interfere with each other.

Planting cucumber seedlings can reduce the waiting time for harvest

Cultivation care

Wherever you plant a vegetable crop, it needs mandatory care. She needs:

watering;
feeding;
ventilation;
loosening;
garter of whips.

Roots need constant air to grow, so it is necessary to loosen the soil frequently. Care is taken with utmost care so as not to damage the stem. In warm weather, keep the windows open; cucumbers need air circulation to grow well. When the first buds appear, add fertilizer to the soil, a layer of no more than 1.5 cm on the surface. Properly selected fertilizer will allow you to quickly achieve the desired result.

The plant garter plays an important role in the development and fruiting of the root crop. Many additional vines form on the bush, so you need to plant while maintaining a distance. Each gardener uses his own system for forming bushes. Do not forget to shoot the bushes, this will direct the plant’s forces into the growth of fruits, so their yield will be higher. For garter, use regular wire, stretching it parallel to the ridge. Using twine, the lashes are tied to the wire. The second method is to use a trellis along which the bushes will curl upward.

Gartering cucumbers in a greenhouse is necessary for proper formation of vines

Organization of watering

The plant loves moisture, but its excess negatively affects its condition: first the leaves will begin to fade, and then the entire plant will die. The soil should not be allowed to dry out, since further sudden moisture may cause the root crop to die. To prevent this, it is better if the polycarbonate greenhouse is equipped with a drip irrigation system. Plants need to be watered with warm water; cold water will slow down their growth. It is correct to water the bush at the root. Water should not fall on the foliage of the plant, otherwise it will cause disease.

In hot summer temperatures, cucumbers are watered daily. There should be 5-10 liters per square meter. In rainy weather, the crop is irrigated only in cases of special need, when fertilizing of the crop is required. Before each watering, check the condition of the soil. It may happen that there will be no need to water the soil, because... they are in normal condition.

Cucumbers need to be watered in the evening. The water for this is prepared in advance; during daylight hours it has time to heat up to the optimal temperature. And the fruits themselves grow more intensively at night. When watering, it is optimal to use a special nozzle for a watering can, so the flow will not be too large.

The surface of the soil is compressed under the influence of water, so it needs to be softened. Thus, moisture and necessary nutrients will reach the root system.

Drip irrigation saves farmer time

Fertilizer use

The soil does not always have the required amount of organic fertilizers. This negatively affects the overall growth of the plant and the development of fruits. Quite often, a lack of organic matter leads to the appearance of barren flowers. Therefore, vegetables need nutritional supplements, which can be added to the soil in the spring. In the Urals this approach is very acceptable. During the flowering period, specialist gardeners water it with manure diluted in water. Mineral types of fertilizers are also excellent. But everything needs to be done in moderation. You can feed the plant no more than five times per season. Don't forget about the foliage. To maintain its green freshness, use a saltpeter solution.

Dangers facing cucumbers

In open ground, plant leaves are exposed to various types of diseases. This is due to weather conditions. Precipitation in the form of rain or hail can lead to the appearance of wormholes on the leaves, due to which the entire seedling as a whole subsequently suffers. Therefore, planting cucumbers in a polycarbonate greenhouse is the most suitable option.

Insects, including greenhouse whiteflies and aphids, are also a threat to the plant. The appearance of aphids is caused by the presence of weeds. The pest attacks the pedicels, and a solution of hot pepper will help get rid of it. Treating the vegetable with a product with a pungent odor will scare off the insect. The whitefly affects the leaves by applying its sap. This subsequently leads to the formation of fungus. To prevent this pest from infesting the greenhouse, gauze or mesh is placed over the ventilation system.

Greenhouse whitefly spreads fungal infection

Another dangerous enemy of vegetable crops is downy mildew. It is easy to recognize, just carefully examine the leaves. The disease is expressed in the appearance of oily spots. The fight against a disease that occurs very often can last for more than one year.

What to do to prevent leaves from turning yellow?

Quite often you can observe a picture even in a polycarbonate greenhouse, where the cucumber foliage begins to turn yellow. When growing fruits in open ground, the appearance of yellowness is influenced by climatic conditions: rain, cool nights (the phenomenon is especially relevant for the Urals). In greenhouse conditions, the reason lies in the lack of elements in the soil such as nitrogen and phosphorus. If you notice the appearance of yellowness, the plant should be fed.

The appearance of yellow leaves is affected by overgrown fruits. These are not zucchini that can grow as much as they want. Fruits should be picked on time and varietal characteristics must be taken into account, because plants with small fruits are often found.

Thus, to grow a crop in a polycarbonate greenhouse, you need very little: attention and timely care. All costs are kept to a minimum, so this method of growing cucumbers is becoming increasingly widespread, especially in the Urals, since the required air temperature for planting occurs somewhat later. This method allows you to enjoy fresh cucumbers not only earlier, but also for a longer period.

Cucumbers are a vegetable crop of the Cucurbitaceae family, which is popular all over the world. You can get a year-round conveyor of fresh produce. This vegetable crop is cultivated in open ground, stationary and film greenhouses, hotbeds and even on a window at home. The formation of the bush and the pattern will depend on the chosen growing method.

Growing cucumbers

Before you start growing plants, you should study their basic characteristics and the necessary conditions for cultivation. A heat-loving vegetable crop will require sufficient moisture and light for normal development and fruiting. Fertility is important and there are a huge number of varieties and hybrids of cucumbers. Pickling or salad, bee-pollinated or self-pollinated species have different ripening periods.

Cucumbers in a vegetable garden

Growing in open ground is a method that does not require additional costs. It needs to be taken care of in the fall. In the spring, the area is leveled, the soil is loosened and enriched with microelements. We should not forget about crop rotation. The best predecessors for cucumbers are vegetable crops such as onions, cabbage, peppers, tomatoes, potatoes and peas. Sowing of seeds begins at a soil temperature of twelve to fifteen degrees Celsius.

How to plant cucumbers in open ground?

Dry or pre-treated seeds are used for sowing. The seed material is subjected to heat treatment, pickled and soaked in solutions of microelements. It is sown using a double-sided tape method. The planting scheme for cucumbers depends on the selected variety and soil composition.

The planting depth is as follows:

light soils - four to five centimeters;
loams - three to four centimeters.

Row spacing for varieties of different ripening periods is:

early ripening - sixty to seventy centimeters;
mid-season and late - seventy to ninety centimeters.

Cucumber hybrids provide a larger area, expanding row spacing up to a meter. You can also use double-sided tape rows. The cucumber planting scheme is as follows:

the distance between the tapes is ninety centimeters;
row spacing - forty centimeters.

In open ground, planting can be done in seedlings.

Pre-grown plants should have two or three true leaves by the time of planting. The scheme for planting cucumbers is the same as for sowing seeds.

Trellis growing method

Cucumbers are capricious plants. They are susceptible to diseases that significantly reduce the fruiting period and the quality of the vegetable crop. To increase productivity, you can use the trellis growing method. The plant's vines will be positioned vertically. The scheme for planting cucumbers on a trellis is as follows:

row spacing - one to one and a half meters;
short-climbing varieties: between holes in a row - fifteen to twenty centimeters;
long-climbing varieties: between holes in a row - twenty-five to thirty centimeters.

Support pillars are installed in the center of the ridge. Their sufficient height is up to two meters. The number of supports is chosen arbitrarily. Moreover, they are installed throughout the entire ridge. Three levels of wire are pulled between the posts at a height:

the first - fifteen centimeters;
the second - one meter;
the third is two meters.

A plastic mesh is attached to the wire, the width of the cells is fifteen to twenty centimeters.

The lashes will feel great. With this method of cultivation, they are less susceptible to diseases, and the fruiting period is extended. The quality of vegetable products improves.

How to grow an early harvest of cucumbers?

Heat-loving plants have specific planting dates. For cucumbers, they are determined by the temperature of the soil and the external environment. The use of greenhouses will speed up the production of early vegetable products.

Preparing the closed ground begins in March. Pre-prepared manure is placed in a greenhouse. Its layer must be at least forty-five centimeters. In order for the insulated ridge to work, it is covered with frames and mats. After three days, manure is added. A soil layer is laid on it. Water with warm water. After the soil temperature in the greenhouse reaches twenty-five degrees, cucumber seedlings are planted in it.

The planting scheme for cucumbers in a greenhouse should ensure the full development of plants. In closed ground conditions, self-pollinating varieties are used. Plants are planted in pairs in the middle of the greenhouse. The number of plants depends on the size of the frame. Typically three to five plants are planted. After this, the frames are covered with mats for several days.

Film greenhouses

You can get early production not only using greenhouse frames. Cucumbers grown in film greenhouses will delight you with a good harvest. This method will require certain costs for the construction of a closed ground structure. However, getting early production is worth it.

In film greenhouses, early ripening self-pollinating varieties and hybrids are used. The soil is prepared in the fall. For the favorable development of cucumbers, it must be fertile and loose. To do this, organic fertilizers are applied. In order to prevent diseases, measures are taken to disinfect the soil.

In the spring, before preparing high beds, mineral fertilizer is applied. This method of growing in a film greenhouse will improve the drainage properties of the soil. Plants will be strong and disease resistant.

To speed up the production of early produce in greenhouses, cucumbers are planted with seedlings previously grown at home.

This event takes place in the second decade of March or early April. At the stage of four true leaves, potted seedlings are ready for planting. In this case, the soil should warm up to fifteen degrees Celsius. Three to four plants per square meter - with this density, in double-row ribbons, cucumbers are planted in a greenhouse.

The landing scheme is as follows:

inter-belt distance - one hundred centimeters;
row spacing in ribbons - fifty centimeters;
between the holes in a row - fifty centimeters.

Cucumbers are grown vertically or by trellis.

when growing

On a personal plot, you can use different methods of cultivating vegetables. Quite often they combine the greenhouse or greenhouse method and the open ground option. In this case, caring for the plant is identical regardless of how you grow cucumbers. The beds require constant loosening and removal of weeds. Plants need a lot of moisture, which is replenished with regular watering. Active growth, normal development and excellent yield are ensured by regular application of fertilizers.

In order for planting cucumbers in a greenhouse to produce not only a large harvest, but also tasty fruits, you need to correctly carry out all stages of growing this plant, from choosing the appropriate variety to harvesting the fruits.

How to prepare a greenhouse for planting cucumbers

In the fall, after harvesting crops and plant residues, the soil should also be completely or partially replaced, especially if plant diseases have been observed. Soil containing 20-30% field soil and with the addition of sawdust is dug up to a depth of 20-22 cm and disinfected with a 7% solution of copper sulfate. If the acidity is high, then neutralize it with lime. Optimal pH 6.5.

Ammonium nitrate, potassium sulfate, and superphosphate are added to the prepared soil. To further improve the health of the soil and improve its fertility, you can plant green manure in the greenhouse in the fall or early spring. Before they begin to bloom, the green mass should be mowed and dug up with soil.

How to arrange beds

The beds are made 25-35 cm high. The optimal width of the beds is 80-100 cm, plants are planted on them in two lines. The row spacing ranges from 50 to 90 cm. The wider the distance, the more convenient it will be to care for the plants.

You can arrange a single-row planting of cucumbers in a greenhouse; the photo below represents just such a planting option. It is more convenient to care for the plants, but the total number of bushes in the greenhouse will be less than when planted in two lines in the garden bed.

If the greenhouse is unheated, then in temperate and cold climates it is advisable to arrange warm manure beds in order to plant cucumbers in the greenhouse earlier. For a manure bed, trenches 35-40 cm deep are dug, fresh manure is placed on the bottom, and prepared and disinfected soil is placed on top with a layer of 15-20 cm.

Some experts recommend placing beds along a north-south line to achieve better lighting for plantings. If you plan to plant cucumbers and tomatoes or other mixed options in a greenhouse, then it is preferable to plant cucumbers on the north side so that the dense foliage does not shade other plants.

How to plant cucumbers in a greenhouse

self-pollinating varieties that do not require the involvement of bees; simply shaking the bushes during the flowering period is enough;
parthenocarpic varieties that do not need pollination at all, however, they do not form seeds, so it will not be possible to make your own reserves;
hybrids that are highly resistant to disease;
self-prepared seeds from previous harvests (should be planted 3-6 years after harvesting).

When to plant cucumbers in a greenhouse

The soil must be heated at least 12° for planting seeds and at least 18° for planting seedlings. Sudden temperature changes in the greenhouse are excluded. Therefore, there is a difference in which beds and in which greenhouses it is optimal to plant cucumbers:

planting in heated greenhouses and manure beds is possible as early as early April;
planting cucumbers in a greenhouse made of polycarbonate, glass and on compost beds can be carried out in late April - early May;
Cucumbers are planted in unheated covered greenhouses on ordinary beds at the end of May.

At what distance to plant cucumbers

If planting is done in wide beds in 2 rows, then a distance of 40-50 cm is left between the lines. Holes for seeds or seedlings in one row are made with an interval of 20-40 cm.

Many people consider it correct to plant cucumbers in a greenhouse when there are 4 bushes per 1 m2. If, for example, you have a 2x6 m greenhouse, then it is optimal to plant 72 cucumber bushes in it: 19 bushes in the outer narrow beds in one row and 34 bushes in two rows in the wide middle bed (17 in a line).

2 ways to plant cucumbers in a greenhouse

Sowing seeds in late April - early May. The method is suitable for busy summer residents who do not have time to tinker with seedlings, but it will take more time until the first harvest, and in addition, there is a risk that not all seeds will sprout.
Planting seedlings. The time before fruiting is reduced, in addition, weak shoots can be immediately discarded. It is better to grow seedlings yourself, this way you will eliminate the risk of disease due to possibly contaminated soil.

When planting seedlings, you should be especially careful with the root system of the sprouts. It is best to grow seedlings in peat cups, from which the plant does not have to be removed for transplanting into the ground. We have described in detail the sequence and nuances of each planting method in other articles, and you can easily find them on the website.

How to care for cucumber plantings in a greenhouse

For good growth and fruiting, cucumber plantings require good lighting, moist air, warmth, the absence of sudden temperature changes and proper formation of the bush. The roots of the plant must remain in the soil; if any protrude above the bed, they are sprinkled with a 2 cm layer of soil.

Optimal temperature

Daytime: 25-30°.
Night: 17-20°.

If cucumbers are planted as seeds in a greenhouse, then until germination the temperature can be maintained at no lower than 12-13°, but after the first leaves appear it must be raised to at least 15-16°. At 10° the sprouts will die. A short-term decline should last a maximum of 2 days.

Watering cucumbers in a greenhouse

Watering rules are quite simple:

the water should be warm;
It should be watered at the root, preferably by drip method;
the optimal time for watering is in the evening, when the water has time to warm up;
immediately after watering or in the morning, light, careful loosening is necessary without damaging the roots.

The sprouts are first watered every third day, then the frequency of watering is reduced to once every 5 days. Immediately after the fruits appear, they begin to water again every third day, and in hot weather every day. When watering, the soil should be moistened approximately 20 cm deep. On the hottest days, in order to reduce the temperature in the greenhouses, the rows are also watered and sprinkling is carried out.

Ventilation

Drafts are not allowed for planting cucumbers. The greenhouse is usually kept open during the day and closed at night.

Top dressing

It is better to fertilize in the evening. At different stages of development, cucumbers need different microelements, so different fertilizers are required in each period:

In the initial period, cucumbers need nitrogen for intensive growth of green mass. Fertilizing is carried out with chicken droppings, manure, and superphosphate is added;
at the beginning of flowering, the bushes are fed with wood ash, and we recommend spraying the flowers themselves with Ovary solution;
in the active phase of fruiting, you will need potassium in the form of potassium sulfate or potassium nitrate, as well as ash to enhance fruiting.

Many gardeners consider yeast feeding with the addition of potassium and phosphorus fertilizers to be a good option for fertilizing. This option promotes intensive growth of bushes.

Bush formation

Forming a bush involves pinching (pinching) shoots in a certain order. Removing certain parts of the plant will allow you to get a better harvest and tasty fruits. In hybrid varieties, pinch the main stem above the 3rd leaf after the last green one. To speed up fruiting, you can tweezer the 4th or 5th leaf.

The formation of varietal bushes is carried out after 8-9 true leaves:

remove all lower shoots and flowers in the lower 3-4 axils;
tweezer the next 4-5 nodes for 1 fruit and 1 leaf;
pinch the remaining nodes into 2-3 fruits or leaves;
after reaching the top level of the trellis, pinch the top of the bush.

Cucumber diseases

Planting cucumbers in greenhouses is susceptible to many fungal diseases, bacteriosis, and anthracnose. They are often affected by powdery mildew and various rots (gray, white, root collar). For prevention, it is better to soak the seeds in fungicidal preparations or choose hybrids that are more disease-resistant.

During cultivation, you need to constantly inspect the plants, checking the leaves on both sides. At the first signs of disease, diseased leaves are removed and the plants are sprayed so that the infection does not spread to neighboring bushes.

After harvesting, to improve the soil health, we recommend sowing green manure (mustard, phacelin, white lupine), mowing the green mass and digging it in with soil.

Harvesting

Overgrown cucumbers lose their varietal qualities, their taste deteriorates, and the formation of new ovaries slows down if there are a lot of fruits left on the bushes. Therefore, the collection of quality fruits is carried out every other day, and daily during the peak of fruiting. This simple rule will allow you to harvest more fruits from each bush, and with better taste.

Popular goods

If you have a summer house, it's time to start a greenhouse on it. For what? At least in order to get a large harvest of everyone’s favorite cucumbers.

How to choose a variety

Features of care

Cucumbers are fairly unpretentious plants; the main thing is to apply fertilizers and water on time. Before fruiting begins, watering is carried out once every three days; approximately 7 liters of water are consumed per 1 m2. As the cucumbers grow, watering increases. During fruiting, the plants will have to be watered once a day.

Typically, watering a greenhouse is done using a watering can. But if you have the opportunity to install sprinklers yourself, it is recommended to do so. The presented system is very popular with cucumbers, who love even and abundant watering. However, it is recommended to water during the day in sunny weather; the windows will have to be closed.

If you want to get a good harvest of cucumbers from the greenhouse, increase the number of female flowers.

How to do it? During flowering, reduce watering. Return the standard frequency of watering to the period when the flowers begin to fade.

Bush formation

It has already been indicated that greenhouses should be equipped with trellises. It is also worth using a pinch. The bush is formed when the eighth leaves appear. You should pinch the flowers in the first three axils at the very beginning. He will also talk about greenhouses .

Monitor humidity and temperature

The temperature inside the greenhouse must always be at a certain level. Before fruiting begins, the temperature should be at least 20 degrees, and at night - at least 17 degrees.

During fruiting:

at night - 20 degrees;
in clear weather - 28 degrees;
on cloudy days - 23 degrees.

Growing cucumbers with your own hands is not easy; you will have to monitor the temperature of not only the air, but also the soil. Sudden temperature changes can cause plant diseases. Among other things, the taste of cucumbers may deteriorate. He will tell you about different ones.

You should also monitor the humidity inside the greenhouse. Before fruiting begins, it should reach 80%, during fruiting - already 90%. We recommend reading .

So, growing cucumbers inside a greenhouse is not an easy task, but every lover of vegetables grown with their own hardworking hands can cope with it. You can find out.

Delicious crispy cucumbers, even in cold regions, are not fiction, but a real fact of life, thanks to simple growing technologies. It's all about a high-quality greenhouse; further, we will look in detail at how to plant cucumbers in a greenhouse.
Creating ideal growing conditions is not all; competent care and proper planting of cucumbers in a greenhouse play a huge role here.

In order to successfully plant cucumbers you will need to choose the right varieties. Planting cucumbers in a greenhouse and the richness of the harvest itself will depend on how well the seeds are selected.
So:

Today, F1 varieties have proven themselves to be especially productive. They are not fussy to care for, but the effect is amazing.
There are special varieties of seeds on the market that are intended for planting in cold regions. The advantage of such seeds is that they tolerate low light very well.

Proven varieties of cucumbers from F1:

Marinda.
Brawler.
Murashko.
Twixie.
Ant.
Hallie.
Bidretta.

Note. There are seeds that are used for the earliest stages; they are shade-tolerant and do not require pollination.

These include:

Stella.
Malachite.
Biryusa.
Lada.

Planting cucumbers in greenhouses for spring structures, these are the varieties:

Vir 516.
Unworn.
Altaic.
Elegant.
Vir 517.

Gribovsky.
May.

Planting cucumbers in a greenhouse, arranging beds

Where there are cold regions, growing cucumbers cannot be done without setting up compost and manure beds, which are done in the spring.
How to plant cucumbers in a greenhouse, what are manure beds and how to lay them:

For these purposes, it is best to use fresh cow manure and add a little horse manure.

Note. This composition will be ideal, since it contains the necessary fertilizing and natural fuel.

Fresh manure is placed in a specially elongated high bed 100 cm wide.
Fertile soil, at least 250 mm, is laid on top of the manure layer and everything is watered abundantly.
Next, the cucumber seeds are sown and distributed evenly, 4 pieces per square meter.

Attention. Seeds do not need to be soaked or germinated in a hot manure heap before sowing.

How to plant cucumbers in a greenhouse? It is best to put 2 grains in each hole, so that later you can cut off the root of a weaker crop.
It is not recommended to thicken the planting any more, as this can reduce the yield.
After the bed is sown, you can cover it with plastic film or light material, which must be stretched over the arcs. Then you will get a small mobile greenhouse in a greenhouse, see photo.

Non-professionals will be interested to know that the temperature in a manure bed can rise so high that you can burn your hand.
This is due to the decomposition process, thanks to which the first shoots appear very quickly.
In the daytime, young plantings can be carefully ventilated. Under an additional canopy on hot beds, young cucumbers receive all the necessary moisture and warmth.

Note. It is very important to take temperature changes and weather conditions into account. If the outside temperature is low enough and the sun is bright, then the seedlings under the film may simply burn.

Therefore, the presence of thermometers to measure the temperature of the air and the soil base is mandatory. The optimal temperature for seedlings should be from +18 to + 30 degrees.
The burning of the manure bed usually lasts for a month, after which the temperature gradually decreases.

Greenhouse and planting cucumbers on compost beds

The problem is that not everyone has the opportunity to purchase fresh manure, and many have no desire to deal with it. In this case, you will need instructions for arranging a warm sawdust bed.
For this you will need:

Sawdust.
Last year's foliage.
Shavings.
Tops.
Any organic material.

Note. The more green waste there is, the warmer the garden bed will become. You can also add the same manure or other components here to speed up and process everything organic.

Steps to creating a compost bed with your own hands:

Before planting cucumbers in a greenhouse, you need to create a compost bed. The principle of creating the device is exactly the same as the previous one.
You must first lay down what will rot, and fill 200 mm of soil on top, after which you can plant cucumber seeds.

Note. For a compost bed, it is best to plant pre-sprouted shoots in peat tablets or cups.

Caring for cucumbers in a greenhouse is exactly the same, under film, but the temperature will be slightly lower.
This method is more suitable for warm regions. How to plant cucumbers in a greenhouse using the compost method in cold regions. If there is no other way out, then it is best to do this already in the spring warming.

After harvesting, do not rush to get rid of the manure and compost beds; they will still serve you. You can subsequently fill in new layers of organic raw materials without digging.
By choosing one of the methods, it is possible to plant cucumbers even in cold regions. For more detailed information, you can watch the training video.

We plant seedlings

The technology for planting seedlings in a greenhouse is also not simple. There are some nuances that need to be considered here.
Seedlings can be planted if:

They have at least 4-5 leaves.
They have been hardened.

So:

Seedlings should be planted around the first half of February in a winter greenhouse. If the greenhouse is spring, then there must be warm beds and technical heating at the beginning of April, and without it at the end.
Conventional film greenhouses with natural solar heating provide for the placement of cucumbers only in early May.
Cucumbers are planted on ridges (preferably 120 by 30 cm), but beds can also be used.
Before planting, it is necessary to apply moisturizing watering directly into the holes.

Then the cubes with seedlings are buried directly into the soil to 1/3 of the height, so that the upper edge is above the surface of the beds.

Making the harvest rich

In order for the harvest to be excellent, the plant will need high-quality nutrition. For this purpose, special mineral and organic soil fertilizers are used.

What exactly:

Soil mixtures are suitable for these purposes. They are scrapped 15 cm on top of the already heated biofuel.
For crop vegetation, the soil base layer must be increased to 25 cm.

How to make a garter

This is the most crucial moment in the formation of a crop; if the garter is done at the wrong time, the leaves may shrink, which will lead to a decrease in yield.
So:

When the cucumbers begin to grow and vertical loops appear, the trellis is immediately tied to the wire. During this period, the crop should be watered moderately.
The wire is stretched along the row at a height of 180 cm.
And for the trellis you will need twine in 250 cm segments. The upper end is thrown over the trellis wire and tied with a free loop under the 2nd or 3rd sheet.
When the phase has reached the 9th leaf, you can begin to form bushes. New branches are pinched off at the lower three nodes (blinding technology), and above the 5th node, up to the wire, the side shoots cling to 2-3 leaves.
As soon as the plant reaches the wire, the main lash is twisted around it several times and fixed.

Considering that a crop such as cucumber loves moisture very much, it is therefore extremely demanding on aeration of the soil base.

If there is no air in the soil, the roots may die. Therefore, soil moisture should be maintained between 60% and 80%.
You should carefully water the plants during the cold winter period, this is done in the morning, on warm days and with warm water, about 25 degrees.

It is necessary to pay attention to ensure that water does not fall on the leaves. Watering is done 2 times a week.
If the days are hot, after 1 day, watering is combined with fertilizing with mineral and organic fertilizers.
