The spring chores of gardeners and gardeners begin with the arrival of the first warm days. If the climate does not allow growing vegetables in open ground, it is necessary to protect the crops with the help of special shelters. Every gardener should know how long cucumbers grow in a greenhouse in order to harvest on time and not overcook the fruits.
How to get cucumbers to bear fruit before frost
Healthy and strong cucumbers should please the owners of the dacha with their harvest for a long time. But often, already in August, cucumber vines begin to fade and by the middle or end of the month, the collection of greens ends. If you notice the first warning signs, do not despair - it is quite possible to extend the fruiting of cucumbers until September and even October!
How to get cucumbers to bear fruit before frost
To do this, you need to know a few subtleties, taking into account which you will be able to harvest before the first frost: 1. You cannot leave ripe cucumbers on the plant. This sharply slows down the growth of young greens and shortens the life of the bush. Cucumbers must be collected constantly as they ripen.
2. In August, when the air temperature is already dropping, the roots of cucumbers begin to absorb nutrients from the soil worse (for reference: if the temperature drops by 1°C, the absorption capacity of the roots decreases by 15%). It would be correct to reduce root feeding by half or even three times, but foliar feeding (by leaves) will provide good support for life during this period.
You will find recipes for proper nutrition of cucumbers in the second half of summer in the article Feeding for cucumbers.
For long fruiting, it is important to feed cucumbers correctly.
3. If the soil under the plants is not mulched, then it is necessary to cover the ground with peat, sawdust, humus or other mulching material with a layer of 4-7 cm - this will protect the delicate surface roots from the cold at night, and will continue to protect them from overheating during the day.
4. Changes in day and night temperatures, cold nights with heavy dew that occur as early as August, and prolonged rains contribute to the development of diseases. If plants get sick, this will significantly shorten their lifespan, so it is very important to take preventive protective measures . How to do this is described in the article “First Aid” for cucumbers: prevention and treatment of diseases.
5. Despite the approach of autumn, it is imperative to continue to stimulate the growth of new shoots and ovaries . To do this, as before, you should regularly remove all yellowed leaves and those located below the fruiting zone - the plant does not need them, and only takes away its nutrients, which are now worth their weight in gold.
Continue to stimulate the growth of new shoots and ovaries 6. If you grow pollinated varieties of cucumbers, you need to think about
attracting pollinating insects .
It’s good when borage (borage), burnet, Siberian buzulnik, black root, oregano, phacelia, chrysanthemums and other plants that bloom in August and September grow in the garden or near the dacha, because in the struggle for the late summer and autumn harvest It's hard to imagine a better support group than bees. 7. To prolong fruiting, some vegetable growers successfully use plastic film to protect cucumber vines from cold rains . By protecting plants from unfavorable conditions and removing the film on fine sunny days, you can significantly lengthen the life of cucumber bushes.
Covering cucumbers with plastic wrap
7. An effective technique is bush rejuvenation . To do this, the lower part of the cucumber vine is laid on the ground and sprinkled with moist soil. New roots appearing on the sprinkled stems begin to actively feed the plant and stimulate fruiting.
In the following video, Pavel Starikov tells and shows how to rejuvenate cucumbers grown in a vertical culture:
But it is not recommended to disturb horizontally growing vines (lying on the ground), because they have naturally, where possible, already formed additional roots. Shifting the shoots from place to place will only destroy these roots. And, as a result, such “help” will reduce productivity.
A well-proven method is sowing cucumbers at several times .

How to feed cucumbers in open ground at the beginning of fruiting
Spray the bushes with urea (50 g per 10 liters of water) or water with herbal infusion (1:5), which we described above. During the fruiting period, root feeding with potassium nitrate (25 g per 15 liters of water) will not be superfluous. This substance will accelerate the formation of fruits, and the green mass will not grow much.
And if you also want to protect plants from diseases, you will be interested in how to feed cucumbers with iodine. To do this, simply add 30-40 drops of iodine and 1 liter of whey to 10 liters of water. Mix the mixture thoroughly and spray the plantings at intervals of 3 weeks before harvesting.
Fruiting dates for greenhouse cucumbers
For cucumbers intended for greenhouses, there are significant differences in the timing of fruit harvest. The entire planned harvest from some varieties can be obtained very quickly, while from others it can take an order of magnitude longer. If the goal is to grow a bountiful harvest in a short period of time, then you should pay attention to quick-ripening varieties and hybrids. They can be called real sprinters in ripening greens. Since they begin to bear fruit very cooperatively, they can literally within a month from the beginning of the first ovaries give away almost the entire harvest that they are capable of, and this is up to 90-95% of its maximum amount. Their further development may be impractical; it is preferable to remove such plants and plant new seeds.
Long-term fruiting hybrids are a different matter. Here the situation is completely different. The cucumber harvest will be extended over several months, the bushes will bear fruit without interruption. In this case, the fruits can be collected little by little, but constantly.
Of course, mass and one-time collection of fruits is more suitable for industrial cultivation for sale. In small private greenhouses, gardeners prefer gradual and longer collection of fresh produce.
We determine the duration of fruiting: how long do cucumbers bear fruit in a greenhouse?
Each variety of cucumbers is somehow different from all other varieties. This may be the speed of ripening, it may be the appearance, or perhaps the number of fruits that the plant is capable of producing. This ability is called productivity. The ideal yield of a particular variety is indicated on the package of cucumber seeds. But several factors influence the number of cucumbers you get.
To make cucumbers bear fruit better, they should be tied up.
Let's figure out how long cucumbers bear fruit in a greenhouse. This will make it possible to understand which varieties of cucumbers are worth purchasing for planting in a greenhouse and which are not.
The fruiting period of cucumbers is different for each variety. But in addition, the yield is influenced by the conditions that are created for their cultivation. If you promptly fulfill all the whims of this demanding plant, you will be able to achieve good returns from them and increase the fruiting period of your seedlings.
Average fruiting time for cucumbers:
- Super early varieties bear fruit – 1 month;
- Early varieties bear fruit - 1-1.5 months;
- Mid-early varieties can produce an ovary in 1.5-3 months;
- Medium varieties bear fruit for 2-3 months;
- Late varieties of cucumbers can bear fruit for up to 2.5-3 months;
In addition, bee-pollinated seed varieties require pollination. Without pollination, you will have only barren flowers on the cucumber tops.
What affects the timing of harvest?
It turns out that the timing of harvest is largely related to the branching characteristic of the cucumber vine, that is, its ability to grow lateral shoots. Hybrids with strong formation of lateral shoots show longer fruiting periods. Such properties are genetically determined in plants.
The thing is that in cucumbers with weak branching, the greens are tied on the main stem. When the harvest is harvested, the plant no longer has the opportunity to develop further; if the side shoots grow, they are very short and in small quantities; practically no new female flowers appear on them. The situation is different with those plants that intensively form side shoots. After harvesting the main stem, they begin a second wave of greens on the side branches. In greenhouses, such shoots, ready to grow from each internode, have to be pinched so that the plants do not interfere with each other.
Some similar hybrids (“Buyan”, “Okhotny Ryad”, “Chistye Prudy”, “Farmer”, “Anyuta”, etc.) have a very valuable feature - they are able to self-regulate branching. In this case, the side shoots do not begin to grow until the harvest is harvested from the main stem. This is very convenient for those who can only come to their dacha a couple of times a week, since the plantings do not have time to become very overgrown.
To obtain good and long-lasting autumn harvests from unheated greenhouses, you should pay attention to hybrids known for their cold resistance and shade tolerance (“Lord”, “Virenta”, “Spring Caprice”, “Moscow Nights”, “Saltan”, etc.). Some hybrids with moderate and weak branching (“Mazai”, “Kozyrnaya Karta”, “Ant”, etc.) show a fairly long fruiting period without forming strong lateral fouling.
Of course, varietal characteristics play a big role, however, much depends on environmental conditions. For example, severe shade, drought or cold inhibit the development of shoots. And vice versa, warmth, good lighting, timely watering and fertilizing increase it, respectively, increasing the yield.
How do fertilizing affect cucumber fruits?
If you don't fertilize your cucumbers during fruiting, most likely nothing will happen. On the other hand, if you feed the plants:
- The taste qualities of the fruit are guaranteed to improve: they become crispy, sweet, healthy, and are stored simply better.
- Secondly, balanced and proper feeding will lead to your cucumbers bearing fruit longer by 1-2 weeks a year.
Thus, proper feeding during fruiting is really important. And it doesn’t matter whether cucumbers grow in a greenhouse or on open ground - in all cases, the crop improves the yield and duration of fruiting, which is all that any gardener needs.
Classification of varieties and hybrids
Today there is a real abundance of varieties and hybrids of cucumbers. Every year this number only increases. How not to get confused and choose the right one that suits specific conditions? Let's start with the classification:
When choosing which cucumbers to grow, you should pay attention to the following:
Please note: do not sow greenhouse-only cucumbers in open ground beds. You can be left without a harvest or get a minimal amount of it.
Features of growing cucumbers all year round in various regions, including the Krasnodar Territory
In our country, they love cucumber; a festive feast is not complete without it. They make salads from fresh cucumbers; they enjoy crunching with pickled or pickled cucumbers. In most Russian regions, cucumber yields are low. This is due to the characteristics of the climate. A short summer with recurrent frosts does not allow cucumbers to create comfortable conditions for growth and fruiting.
Only in the southern regions is the entire growth cycle of the cucumber provided with sun and warmth. One of these areas is the Krasnodar Territory. The climate there is generally characterized by an excess of solar radiation with moderate humidity, so Krasnodar vegetable growers periodically face the problem of water shortages. But there is a solution to this problem, such as mulching the soil to retain moisture. Interestingly, in the Krasnodar Territory, cucumbers can be grown all year round, even in unheated greenhouses - for this purpose, structures with foil walls are used, which allow maximum heat retention inside.
In other regions, especially in Siberia, in winter and autumn the length of daylight hours is not enough to obtain a good harvest. When growing this vegetable in Siberia and other areas, it is better to consider methods of additional lighting and heating in a greenhouse or garden bed, for example, supplementary lighting with various lamps.

How to maximize the fruiting period of cucumbers?
You wait a long time for cucumbers, you pick one a day, then for 3-4 weeks you don’t know what to do with them, and then that’s it! What to do? Summer is not over yet and I really want to extend the harvest for as long as possible. And cucumbers age and become bitter. We are offering to you
6 Easy Ways to Rejuvenate Cucumber Vine
Trimming leaves, shoots and cucumbers
The first and most important thing to do is to trim off old yellowing, drying and diseased leaves. By the way, while you are doing this, carefully inspect the vines; perhaps you forgot to remove some part of the crop and these cucumbers have outgrown. Be sure to remove them; ripening cucumbers are a signal to the plant about the end of the growing season. Harvesting on time is very important if you want your canes to age as slowly as possible.
Overripe cucumber
So, first we cut off the old leaves and the “cunning” cucumbers hidden in the foliage. Then, trim off the excess stepsons. Leave those on top, 5-6 pieces per lash. Remove the lower leaves and shoots if you have not done so before.
Trimming cucumber leaves
Foliar feeding of leaves
Urea. Nitrogen fertilizers, such as urea, are suitable for foliar feeding. Spraying with a weak solution of urea (10 g per bucket of water) stimulates the development of new leaves.
Epin. Foliar feeding is carried out at the rate of 1 ampoule per half bucket of water.
Root feeding of cucumbers
Green fertilizers. Green fertilizers are very useful for cucumbers, especially those based on nettle, which contains a large amount of nitrogen. Read more about their preparation>>>
Green fertilizer for cucumbers
Mulching the soil under cucumbers
This is always a useful agricultural technique. You can mulch cucumbers with peat, humus or mowed grass.
Stem rejuvenation
This procedure is not simple and many summer residents may need to abandon it, because if carried out incorrectly, it will lead to the death of the plant, and not to prolonging the period of cucumber yield.
It consists of lowering part of the whip onto the ground and covering it with earth. To do this (it’s best to do it together), the cucumber lash is cut from the rope (only the rope is cut, not the lash) and carefully lowered a third to the ground and tied at this height. That part of the lash that ends up on the ground (with the leaves removed!, see point one) is sprinkled with soil.
What is the danger? when lowering the whip, you can
- break the fragile stem (cucumber vines dry out very quickly and become brittle),
- pull out the plant along with the root system.
Replanting cucumbers in mid-June
Cucumbers, like peas, can be grown in several periods:
- the first one is planting seedlings in April, these cucumbers will go in June and will be the very first,
- second, sowing seeds in the ground in early May, this is for the main harvest in July;
- third, this is replanting cucumber seeds in mid-June, you will receive this harvest in August.
Growing cucumbers in a greenhouse: Choosing a variety
Today you can find about 80 different varieties that are suitable for planting in open ground and about 60 for greenhouse cultivation. Hybrids (marked with the name F1) have proven themselves best for greenhouses.
How long does it take to grow cucumbers?
The ripening period directly depends on the selected seed variety. There is a special classification of varieties that is divided into three categories.
You can read more detailed information about the ripening period of cucumbers on the package of seeds you purchased. If you have not bought seeds yet, then you have the opportunity to choose the variety that is right for you.
difference in growth time between open ground and greenhouses.
Don’t forget about the possibility of growing seedlings that will accelerate the growth and percentage of surviving plants. Growing seedlings will take more time, but the speed of growing already in the ground is noticeable when compared with planting seeds. We have a detailed article on growing seedlings, we invite you to read it.

Using the hydroponic method to grow cucumbers
Using the hydroponic method allows you to grow plants without soil. Instead of soil, an artificial environment is used. Expanded clay, crushed stone, and vermiculite are used as substrates. The nutrient solution is delivered to the roots by drip or flooding according to a specific schedule.
It is better to purchase mineral solutions in specialized stores. The purchased solution contains everything the plant needs.
Recently, the use of corks, cubes and mineral wool mats as a substrate has become popular. When preparing cucumber seedlings, observe the following order of operations:
- Seeds are planted in seedling plugs to a depth of 1 cm. Seeds germinate in 2–3 days if the temperature is maintained at 20–25° C and humidity 75–80%.
- After a week, the plugs with sprouts are placed in cubes.
- Seedlings develop in cubes from 3 to 5 weeks, then they are placed in mats soaked in a nutrient solution.
Preparing cucumber seedlings using the hydroponic method
Watering is carried out through droppers installed in the mats.
The principle of supplying nutrients by flooding is as follows: a tray with plants is fixed at an angle, and a reservoir with a mineral solution is located under the tray. Using a pump, the tray is filled with solution to the maximum level. Excess solution flows back into the reservoir. A certain amount of solution always remains in the tray.
The supply of mineral solution when growing cucumbers is carried out using the method of periodic flooding
Pros and cons of hydroponics
Advantages of using the hydroponic method:
- the ability to control all processes of plant development, use solutions of different compositions for each stage of growth;
- saving water;
- saving of nutrients, all nutrients are completely absorbed, nothing goes into the soil;
- no weeding needed, no weeds;
- Productivity increases because the plants are healthy;
- The ripening time of cucumbers is reduced.
Hydroponics is suitable for small spaces. First, roots take up less space, so you can fit more plants in a small area. Secondly, hydroponics does not require much updating after each harvest, as when using soil. Disadvantages of the hydroponic method:
- there is a high probability of destroying all the plants when preparing the wrong solution;
- Strict temperature control is required; if overheated, plants die;
- This is an expensive growing method, high energy consumption for lighting and climate control.
Growing cucumbers in a greenhouse: Planting
Seeds or seedlings?
The main advantage of seeds is the time saved. I planted it in the ground and forgot about it. You need to tinker with the seedlings. But the main thing is that seedlings mean stable and rapid plant growth. Before planting, seedlings should already have 4-5 leaves.
Do not forget about the distance between the bushes, otherwise they will “clog” each other. The seedlings are planted in the ground to a depth of about 15 cm.
How to make the perfect soil with your own hands?
Properly prepared soil can increase the expected yield significantly. Before planting seedlings, you must be sure that the soil already contains all the microelements necessary for cucumbers. After all, growing in depleted soil is not profitable.
Fertile land as a percentage
Peat | Humus | Field soil |
50% | 30% | 20% |
Peat Humus
First, the soil is cleaned of the remains of previous plants. Disinfect with a 7% solution of copper sulfate. Leave alone for one month.
The spent soil this season needs to be prepared for the next planting. To do this, we add fertilizer.
Mineral fertilizers: sulfate, superphosphate or urea.
Organic fertilizers: manure, bird droppings, peat, silt, sawdust, shavings and tree bark.
Maybe compost?
Compost is a waste-free production of fertilizer from food debris, weeds, and fallen leaves that is made with your own hands.
Many gardeners consider compost to be the best natural fertilizer that can not only enrich the soil and grow crops to the envy of their neighbors, but also cope with human food waste (skins of potatoes, cucumbers, carrots, etc.), recycling tree branches, fallen leaves and scraped grass.
You can read more about compost in our material.
Ways to plant cucumbers in winter
In winter, cucumbers are grown in heated greenhouses, basements and apartments. Growing cucumbers consists of the following stages:
- processing of seed material;
- seedling care;
- preparation of the premises;
- watering;
- feeding;
- bush formation;
- harvesting.
Agricultural technology is the same for all types of buried soil structures. The differences will only be at the stage of preparing the premises.
Seed preparation
Having chosen the hybrid varieties you like, check the seeds for germination. They are poured into a glass, filled with water, and stirred. Specimens that have settled to the bottom are left for planting. Then the seeds are placed in a solution of potassium permanganate (1 gram per 0.1 liter of warm water) for 20 minutes and washed in cold water. After disinfection, the seed material is soaked for 12 hours in one of the nutrient solutions to choose from:
- 1 teaspoon of Agricola-Start liquid fertilizer per liter of water;
- 3 teaspoons of bacterial fertilizer Zaslon per liter of water;
- 1 tablespoon of organic fertilizer Barrier per liter of water.
Seeds germinate for one to two days. Recently, Dutch seeds have appeared on sale, which, due to special processing, have high germination rates and are protected from many diseases. When preparing these seeds, heat treatment, dressing and calibration were carried out. They can be embedded in the soil after soaking for two days. Popular Dutch hybrids:
- Angelina F1;
- Hector F1;
- Bettina F1;
- Dolomite F1.
Growing seedlings
Preparing seedlings takes 4 weeks and consists of the following:
- Cups measuring 8x8 or 10x10 are filled with prepared soil (2 parts each of peat and humus, 1 part old sawdust) or ready-made soil.
- Sprinkle with a solution of Ideal liquid fertilizer and sow the sprouted seeds. During the preparation of seedlings, make sure that the temperature does not fall below 12–15° C.
- Feed with a solution of organic fertilizers. For example, dissolve Ideal fertilizer in a bucket of water. The solution consumption is half a glass per plant. The appearance of the second true leaf is a signal for the first feeding.
- When the fourth true leaf appears, feed it a second time. To prepare the solution, take a teaspoon of urea, superphosphate and potassium sulfate per 10 liters of water.
The seedlings are ready for planting if they already have five or six true leaves. The root system must be well developed. The seedlings are planted in a permanent place according to a 50x50 pattern in heated greenhouses and basements. If cucumbers are grown in an apartment, use a separate five-liter pot for each seedling.
In an apartment, plants can be planted without growing seedlings. With this method, the roots of the cucumbers will not be damaged during transplantation. The seeds are placed directly into the pots where the cucumbers will be grown. To maintain moisture, the pots are covered with film. After the shoots emerge, the film is removed and the pots are placed closer to the light.

Technology for growing cucumbers in a greenhouse
Of course, more than one book could be written about growing technology. But we will touch on the very basics that you should know before starting work.
Self-pollinating varieties of cucumbers can be planted 0.5 m between bushes and 1.5 m between rows.
Before the fruits appear, the temperature should be at least +22 in the sun, +20 in cloudy weather, +17 at night.
When the fruits appear, the temperature should increase slightly. In sunlight +27, in cloudy weather +24, at night +20.
A sharp change in temperature can cause diseases in cucumbers!
The air humidity in the greenhouse should be 80-90%. The culture loves moisture very much, and almost all of it itself consists of water.
Before planting, the seeds are soaked using a special technique. This will accelerate the growth of crop germination after planting in the ground. There is also a technique for “hardening” seeds, which will increase the frost resistance threshold of plants. All this is done before planting the seeds in the ground.

Rules for caring for cucumbers in a greenhouse
When are cucumbers planted in a greenhouse? Seedlings that have reached 25 days of age for planting in a greenhouse . Before replanting, the soil is thoroughly loosened, plant remains and other foreign inclusions are removed from it. It is recommended to disinfect the soil by spilling a hot solution of potassium permanganate or copper sulfate.
How to plant cucumbers in a greenhouse correctly, at what distance? The scheme for planting cucumbers in a greenhouse is as follows: the distance between cucumbers in the greenhouse should be 35 cm from each other, wide row spacing is required.
Before planting, humus mixed with wood ash is laid out in the holes. In order not to injure the delicate roots, cucumbers (seedlings) planted using the transshipment method , that is, they are placed in a hole along with a lump of earth.
If the plants were grown in peat pots, then the further cultivation technology is to cut them for better root germination. Freshly planted seedlings are sprinkled with soil , the surface is slightly compacted. Seedlings should not be buried, as this may cause root rot. After planting, the plants are watered and sprinkled with a thin layer of peat.

How to care for cucumbers in a greenhouse? Cucumbers need high humidity . Ventilate the greenhouse only in warm weather; drafts are contraindicated for plants. The ideal humidity level is from 75 to 85% . Plants should be watered with warm, soft water, preferably settled.
In warm seasons, watering is carried out twice a week ; in hot weather, it is recommended to water the plants every other day. It is better to do this early in the morning or before sunset.
The temperature in the greenhouse for cucumbers during the fruiting period should be within 25°C-30°C. The total lighting of a greenhouse for growing cucumbers should be at least 12 hours.
The soil under the plants is regularly loosened . This improves air exchange and breaks up the dense crust that forms on the soil surface. During the season, plants are fed 4-5 times with liquid complex fertilizer or organic matter.
It is preferable to alternate potassium-based mineral supplements with diluted chicken manure or mullein. It is useful to water the plantings with an aqueous infusion of weeds: nettle, woodlice, quinoa, sedge.
plants from insect pests . Cucumber plantings can be affected by aphids, spider mites, and naked slugs. (Read about how to fight them on cucumbers here)
Soapy water helps against aphids; flying insects are destroyed using insecticides . You can use toxic drugs only before flowering begins.
Spraying with herbal remedies or a solution of potassium permanganate is also useful. They help not only against pests , but also against powdery mildew, real or false.
Features of growing cucumbers in polycarbonate greenhouses from “A” to “Z”.
How to properly grow cucumbers in a polycarbonate greenhouse? To grow cucumbers in winter, capital insulated structures are needed . The best option is greenhouses on a foundation made of cinder blocks and a metal frame, covered with sheets of cellular polycarbonate.
Such a greenhouse is equipped with ventilation windows , double doors with a vestibule, and a drip irrigation system. More expensive industrial buildings are equipped with a fogging system and automatic curtains for shading on hot summer days.
How to plant cucumbers in a polycarbonate greenhouse? In summer, cucumbers can be grown in light greenhouses without heating. They are covered with film, but it is better to use polycarbonate. It does not interfere with normal insolation, but scatters the hot rays of the sun well, preventing them from burning tender leaves.
An ideal microclimate is created in a polycarbonate . Together with cucumbers, you can grow spicy herbs, seedlings of flowers or vegetables, early cabbage and radishes. We hope we have explained in general terms how to grow cucumbers in a polycarbonate greenhouse.
Additional crops are sown between cucumber bushes. They not only increase the productivity of greenhouses, but also protect cucumbers from weeds and additionally nourish the soil.

How to heat greenhouses?
You can do it yourself, or you can buy ready-made solutions. Heating systems can be divided into the following types:
The most common heating systems are stoves (potbelly stoves). This method was used to heat people in ancient times, but the method is still effective. The subject of combustion can be any flammable object. Leaves, manure and straw combinations (biofuel), wood, coal and much, much more.
First, we decide what is the most profitable way to heat our greenhouse, otherwise it makes no sense. After choosing the type of heating, we find a suitable scheme for installing a boiler (heater) ourselves or buy a ready-made solution in a store.
If you live in a region with low temperatures, it is necessary to perform additional insulation, which also includes insulation of the foundation.
How to properly illuminate a greenhouse?
Cucumbers need light. There should be no compromises here. With a lack of light, plants grow slower and are more susceptible to disease.
Do not use incandescent lamps to illuminate cucumbers. This is not only financially expensive, but can also cause damage to the plants (burns).
Amateur gardeners conducted tests with lighting, where LED lamps showed excellent results. The choice is yours.
Even at the planning stage of the greenhouse, it is necessary to make the maximum possible exposure to sunlight on the plants.
What area is needed for a greenhouse, what size is a standard one?
Everything is individual. There is no standard as such. You yourself look at the availability of free land or calculate the yield in kg per m2. The main thing is to be able to move without restricting movement. The height has its own standard of 2.2 m. This is the height at which you can safely walk and not worry about your head.
There should be plenty of space in the greenhouse, but do not forget that you need to heat it in cold weather (if you are going to get several harvests a year).
Necessary elements for growing
In order to increase productivity and reduce the ripening time of fruits in closed ground conditions, two conditions must be met simultaneously: the greenhouse must be of suitable size, and it must contain all the necessary equipment for caring for plants. The greenhouse structure can be frame, film or polycarbonate. The latter is sealed, which allows you to maintain the microclimate created inside.
Minimum parameters: at least 10 m2 - area and 2 m - height.
How to revive cucumbers in August. How to save cucumbers from August stress

In order for them to grow and begin to supply the cucumbers with useful elements, we raise the level of soil in the garden bed, adding it and bringing its layer to 2-3 cm. Ordinary soil will not work, you need compost.
Add compost to bed 3. On the same day, according to the instructions, dilute it in an Epin-Extra sprayer and generously spray all the plants: leaves, stems, ovaries and fruits.
Spray the cucumbers with Epin-extra solution 4. 2-3 days after treatment with Epin-extra, dilute several tablets of Alirin-B in a small amount of water. Then pour the resulting concentrate into the sprayer, add water and spray the cucumber plants. This must be done in order to protect plants from diseases. Approximate proportion: 10 Alirina-B tablets per 2 liters of water.
We dilute several tablets of the drug “Alirin-B” in a small amount of water. Treatments with these two drugs with a break of 2-3 days must be repeated once a week for 2-3 weeks.
