Do-it-yourself grapes will always find a place on your kitchen table - either in the form of sweet, large and tasty berries, or in the form of homemade wine. In addition, surplus grapes can always be sold or donated to your friends and acquaintances. But how to achieve a bountiful harvest of this crop in the middle lane, where light and heat may be lacking? The solution to this problem is growing grapes in a greenhouse.
Why grow grapes in a greenhouse?
Compared to open ground, growing grapes in a greenhouse has many advantages. This is especially pronounced if your land plot is located in the middle latitudes or slightly north of them.
- Creation of favorable temperature conditions - even without artificial heating, the greenhouse will be 2-5 degrees hotter. To humans, this may seem insignificant, but for grapes it is very important.
- The ability to get the harvest earlier - with the correct cultivation technology and favorable conditions provided by the greenhouse, the crop can be obtained 2-4 weeks earlier than in the open field. This is especially important for late grape varieties that do not have enough warmth outside the greenhouse for this.
- No problems with insects and diseases - the greenhouse will partially solve the problem with wasps that damage and eat berries. In addition, mildew or powdery mildew are extremely rare indoors.
- No need for chemical treatment - since the grapes in the greenhouse are protected from diseases and plants, then they need to be processed much less often. As a result, the cost of berries is reduced, their safety and environmental friendliness increase.
- Frost protection - the casing and foundation of the greenhouse will protect the plants inside from sudden temperature changes. This is especially important for those grape varieties that do not have sufficient cold resistance.
- No problems with berry cracking - there is no precipitation in the greenhouse, optimal values of temperature and humidity are maintained.
- High yield, which depends on the density of planting seedlings (from 4 to 8 kg of berries per square meter of the greenhouse).
- Convenient working conditions - there is no gusty wind in the greenhouse, it is not so cold in autumn or winter. And with proper arrangement of trellises, the harvesting process will be significantly simplified.
- The ability to use the greenhouse for growing other crops - in the space between the trellis, you can grow strawberries, garlic, spinach, onions or flowers.
It should be borne in mind that to start growing grapes, significant initial investments will be required - for the purchase of seedlings, the arrangement of the foundation and the construction of a greenhouse. Also, you will need to spend a lot of effort on caring for this agricultural crop, and at the same time it will not begin to produce crops immediately. But all the costs will more than pay off with a large number of tasty and nutritious berries that you can either consume yourself or sell or use to make wine.
Choosing varieties
The process of growing grapes in a greenhouse begins with the selection of a variety. If you are a beginner and have not dealt with such a crop before, then give preference to early and frost-resistant varieties, which are guaranteed to give a plentiful and high-quality crop in the greenhouse. These include various types of raisins, Korinka Russkaya and Michurinsky. As soon as you successfully get a harvest from early and frost-resistant grape varieties, move on to its other varieties, designed for cultivation in the southern regions, in the Kuban or in Moldova.
Important! When planning to grow grapes in the Urals, North-West or Siberia, equip a greenhouse heating system and artificial lighting. They will help plants to cope with the lack of sun and heat, which will be noticeable even taking into account the microclimate of the greenhouse.
Some of the varieties that are suitable for growing in a greenhouse located in the middle lane are shown in the table below.

Features of the greenhouse for grapes
A greenhouse designed for growing grapes has significant differences in its design from traditional greenhouses for tomatoes and cucumbers. Let's consider separately all the features that need to be taken into account when building.
Dimensions. A greenhouse for growing grapes must have a considerable height - from 2.5 to 3 meters or more, depending on the design and size of the trellises. The optimal building area designed to meet your own need for grapes is 25-30 m2. Larger greenhouses can be used to grow berries for sale or wine production.
Foundation. The soil in the greenhouse for grapes must be reliably protected from freezing. In addition, without a foundation, weeds, pests and uncontrolled drafts will penetrate inside. Build a shallow concrete strip foundation.
Sheathing. For a greenhouse, it is desirable to use transparent cellular polycarbonate - a material with high light transmission and good thermal insulation properties. Plastic wrap is acceptable, but only for unheated structures.
Frame. Grapes do not like haste and do not start producing a good harvest immediately, therefore the greenhouse must be durable and have a significant service life. And as a material for the frame, the optimal choice in such conditions would be a galvanized steel profiled pipe - it is strong enough, durable and easy to work with.
Heating. If it is planned to grow grape varieties that are not designed for cold weather, then the greenhouse will need heating.To do this, you can use infrared lamps suspended from the ceiling (in this case, you will need to significantly strengthen the frame of the building), or a heating cable brought under the ground of the greenhouse. For lovers of simple options, the arrangement of conventional heating radiators is suitable.
Lighting. Southern grape varieties in Siberia or the Northwest may lack sunlight. This deficiency can be corrected with the help of special fluorescent lamps. They are presented in luminescent, LED and sodium subtypes.
Ventilation. For a small greenhouse designed for growing grapes for own consumption, two vents located in the gables of the building will be enough. If it is planned to produce berries or wine for sale, then the greenhouse should be larger, respectively, the number of transoms should increase. To ensure an optimal microclimate, equip all vents with thermal cylinders that open and close the doors at a certain air temperature inside.
Important! Unlike other crops, grapes do not require frequent watering. But with its manual (watering) implementation, you have to spend a lot of labor and time. The arrangement of an automatic irrigation system controlled through a conventional valve or a special microcontroller will help to partially solve this problem.
Do-it-yourself greenhouse trellis
The main element of the greenhouse for growing grapes are trellises - trellises that serve as a support and a means of controlling the direction of growth of agricultural crops. There are many varieties of this design, vertical single-plane and horizontal T-shaped trellises are best suited for use in a greenhouse. Let's see how they are created.
Roughly speaking, vertical single-plane trellises are a fence made of wooden pegs or metal pipes, between which a wire is stretched with a certain pitch. The vines are attached to the wire and shaped in a certain way.
As a result, it becomes possible to grow a larger number of bunches per unit area and, accordingly, to obtain bountiful harvests. You can equip vertical trellises as follows.
Step 1. Inside the greenhouse, mark out the places for the pegs.
Step 2. Drive in stakes or pipes at the desired points. For the first, use a beam of 50x50 mm, for the second - steel pipes with a cross section of 7-10 cm.The depth into which they are driven is 1-1.5 m, the height of the trellis above the ground level is 3-3.5 m. The distance between the individual stakes or pipes - from up to 6 m.
Important! Treatment of wooden stakes with protective compounds is undesirable - these compounds can subsequently harm the vine, leaves or berries. Copper sulfate is a safe alternative.
Step 3. At a height of 50 cm from the grape seedling, pull a wire with a cross section of 3 mm. Attach with wire loops, nails or metal staples.
Step 4. Pull the second one 35-40 cm above the first wire.
Step 5. Repeat step # 4 two to four more times (depending on the required height of the trellis).
Step 6. At a distance of at least 0.5-0.75 m, start installing a new trellis.
Advice! The arrangement of the cornice will help to increase the useful area of the vertical single-plane trellis, as in the image below.
Horizontal trellises are arranged somewhat differently.They can be either T-shaped supports, between which a wire is stretched at intervals of 30-40 cm, or a lattice using thick metal pipes as a support. The latter design turns out to be quite complex and heavy, but at the same time very convenient for harvesting - bunches of berries hang at the level of the head of an average person and there are no problems with removal. In addition, strawberries or other similar crops can be grown under these horizontal trellises at the same time.
Important! Regardless of the design, the top rows of the trellis should not be closer to the greenhouse cladding than 30-40 cm. Otherwise, there will be a risk that the grapes will get sunburn.
Planting grape seedlings
It is necessary to start planting seedlings in late winter or early spring, it all depends on the grape variety and its frost resistance, while the plant material must meet the following requirements:
- absence of fungus and diseases;
- strong and healthy roots;
- lack of mechanical damage;
- no traces of freezing.
The place for planting the seedling should be no less than 30-50 cm from the greenhouse sheathing. The interval between plants in a row depends on the specific variety and can reach from 0.5 to 1.5 m. The preparation and implementation of planting is carried out according to a certain technology.
Step 1. Dig a hole 80x80 cm and a depth of 70 cm. It is advisable to equip the trellises at the same stage.
Step 2. Place a quarter of a bucket of wood ash on the bottom.
Step 3. Equip a drainage layer with a thickness of 20 cm. To do this, fill in expanded clay or gravel. Insert a 10-12 cm tube into the resulting layer, which will be used for watering. Its height above ground level should be at least 5-10 cm.
Important! The drainage layer does not have to be arranged directly under the future seedling. It can be arranged nearby, at the entry point of the irrigation tube. In this case, the depth of the pit directly under the seedling is reduced to 50-60 cm.
Step 4. Prepare the seedling substrate. There are two recipes. In the first, 1 part of sand is used for 2 parts of humus and 5 parts of fertile soil. In the second recipe, for 1 unit of sand mass, 2 units of peat and 4 units of loam are taken. Add fertilizer or lime to the substrate (the latter is taken from a ratio of 100 g per bucket).
Step 5. Pour the substrate into the hole with a layer 20 cm thick and pour water over it. If the substrate has settled and decreased in volume, add more.
Step 6. Plant the seedling in the soil, straighten the lower root system and add another 15-20 cm of substrate on top. As a result, the remaining depth of the hole should be 10-20 cm. Orient the seedling parallel to the greenhouse sheathing.
Advice! To plant a large number of seedlings, you can dig a trench of the appropriate depth, width and length.
Grape care and pollination
The main principles of ensuring good conditions for grapes are the right temperature, access to sunlight and the formation of shoots.
The temperature is regulated by heating and ventilation. The optimal regimen for grapes depends on the stage of growth. So, in the spring, at the stage of bud formation, the plant needs + 10-20 ° C during the day, at least +8 ° C at night. During the flowering period, the optimum temperature during the day is + 25 ° С, at night + 15 ° С.And when the berries begin to ripen and fill with juice, it should be a little hotter in the greenhouse - + 30 ° С during the daytime and + 18-20 ° С in the dark. When using artificial heating, try to reproduce these cycles so that the plant is not stressed and produces the best yield.
Important! The above values for optimum temperatures are general. More accurate values depend on the specific grape variety, therefore, before choosing each of them, read in detail the description and experience of working with this or that species.
Providing access to sunlight is achieved through the correct design of the trellises and their correct location. In addition, make sure that the vines on the lower wires are not shaded; if necessary, it is permissible to cut a certain number of sheets in that place.
Shoot formation is a very important part of grape care. As a result, you should form strong branches with fruiting vines. Stepsons (also called shoots of the second order) and weak branches should be cut to the first "eye". This way, you will not allow the plant's resources to be wasted on parts that will not yield crops. In addition, you need to trim the tops of the shoots several times each season. Forming grapes is a whole art, and for a better understanding of the process, you should consult a specialist or reference literature on viticulture.
Inspect the bunches regularly. If damaged, rotten or diseased berries are found, cut them off immediately. In addition, sometimes it is necessary to thin out clusters of small fruits and weak branches in order to avoid overloading and “direct resources” to higher quality berries. The optimal distance between branches during ripening is from 6 to 8 mm. Carry out thinning carefully, using long and thin scissors, so as not to cause additional damage.
Since in the greenhouse, most likely, there will be no bees, the pollination of the grapes must be carried out independently. Perform the event after the opening of the flowers of the plant. Everything is quite simple - light and quick blows are applied along the stem. An alternative way is to tap the flowers of one plant and then transfer the pollen on the hand to another.

Watering and feeding
It is worth noting that the grapes do not require frequent watering. Excess moisture can damage the crop and cause the berries to crack. Perform the first watering even before planting the seedling, when forming a hole - 20 liters of warm water for each. Then the same amount - after planting, the place should be well saturated with water, but make sure that due to excess moisture the plant does not "drown" and does not start to rot.
After seven days, watering is repeated, while mulching the soil in the hole with the seedling is also performed. Further, in the summer, the grapes are supplied with water once a week, watering should be done either in specially dug holes and grooves, or in a tube inserted into the drainage layer - most of the moisture should flow to the lower roots of the plant. During the ripening of the berries, the frequency of watering is reduced so that the fruits do not crack from an excess of moisture. In the future, plants with an age of several years are watered as needed, carefully controlling the level of moisture in the earth - the latter should not be overdried, but its transformation into sticky and wet mud is also undesirable.
Top dressing of grapes is carried out in four stages:
- in the spring when disembarking;
- 15-12 days before flowering;
- when forming berries with a diameter of a pea;
- at the beginning of ripening.
In all cases, superphosphates, potash and nitrogen fertilizers are used. It is allowed to use top dressing in liquid form, as well as slurry. The exact values of fertilizers that need to be applied to each plant depend on the specific variety, be sure to check this point when buying seedlings from a grower.
Growing roses in a greenhouse for sale
Growing roses in a greenhouse for sale is a profitable business, as the demand for the queen of flowers does not decrease even during the winter months. Depending on the region, the profitability can be 200% or more, and the payback period does not exceed two years.
Preparing grapes for winter
After harvesting, caring for the grapes does not end - you need to prepare for the winter. Shoots must be protected from hypothermia. To do this, they are removed from the trellis wires and laid on the ground. It is desirable that this is the bottom of the trench, which lies below ground level. Then the shoots are covered from above with straw, spruce branches or other similar materials. It makes sense to put poison from mice there as well, otherwise rodents in the greenhouse can cause significant harm to plants.
If it is possible to temporarily dismantle the roof of the greenhouse - do it, the snow that has fallen will help protect the grapes from hypothermia. Also, do not forget to make a snow shaft around the walls of the greenhouse in December so that the soil inside does not freeze too quickly.
As mentioned above, growing grapes in a greenhouse is a complex, laborious and long process. But the reward for the effort expended is also appropriate. And for experienced gardeners, grapes from greenhouses can be a good source of income.
Pros of growing in a greenhouse
Growing grapes in a greenhouse is relevant both for the central zone of Russia and for the southern regions. In the first case varieties can be grown, which simply do not have time to ripen in open field conditions, and in the south you can get a harvest of berries much earlier than the established date. Besides:
- growing in greenhouse conditions allows you to protect the plant from the hardships of nature (rain, wind, fog, temperature changes);
- it is much more convenient to care, especially in spring and autumn;
- flavoring the quality of the berries is no worse those that ripen on plants in the open field;
- berries crack less, as they are protected from rain drops;
- the shelter allows you to protect from insects and birds, as well as from many diseases and pests. The number of chemical treatments against mildew, oidium is reduced;
- next to grapes you can plant other crops in the aisles: strawberries, radishes, turnips, herbs (parsley, onions, dill, basil);
- sometimes gardeners in the same room grow tulips and other bulbous flowers for further sale.
Selection of varieties
Different grape varieties can be grown in greenhouse conditions. The experience of winegrowers shows that the most successful among them are table varieties with an early or very early ripening period:
Bulgaria resilient (Queen of Paris) is a Bulgarian amber yellow grape. Differs in high resistance to diseases, does not require chemical pollination, bears fruit well.
Song (White miracle) - very early ripening. The berries are large, sugar, yellow-green in color.
Laura - gives high yields, is distinguished by large bunches and juicy berries. With good care, the mass of individual bunches can reach 2-2.4 kg.
Transparent - a good variety for eating, preparing homemade meals and drinks. The berries ripen, sugar and aromatic.
In addition to the listed species, you can give a choice: Arcadia, Early Northern, Russian Korinka, Moscow Stable, Michurinsky and others.
Some growers acquire seedlings of different forcing dates, which allows you to harvest throughout the warm season from spring to late autumn. You can combine early varieties with later ones.
note that not every variety suits well for cultivation in a greenhouse, for example, Dekabrskiy and Vostorg bear fruit better in open field conditions.
Greenhouse requirements
How to grow grapes in a greenhouse? Before you start planting vines you need choose and equip the premises correctly.
- arched structures are considered the most successful. These are often chosen for growing flowers;
- the height of the greenhouse should be between two and a half to three meters. The total area is selected based on the goals of cultivation. For eating berries and homemade preparations a small room is suitable, and for sale, its area can be more than 20-30 square meters.
You can find out on our website how to build and strengthen a polycarbonate greenhouse, how to make an arched, single-slope (wall), from window frames or choose a ready-made greenhouse, as well as how to correctly position a building on a site.
Types of greenhouses for grapes:
- Film - well suited as a seasonal shelter... They allow you to protect the plant from the vagaries of nature, support its development and growth, and get a better harvest.
- Shelter made of polycarbonate - suitable for off-season (year-round) use. They are equipped with a supporting structure and special air vents.
In specialized stores, there is a wide selection of designs that can be purchased from the site. To each design detailed assembly instructions are attached and use. Some firms even offer assembly services for such a room.
This increases your cash costs, but minimizes the hassle and time wasted. Many gardeners prefer to make such designs. independently from improvised means, because it saves money costs by 4-5 times.
Preparatory work
Pay attention to the preparatory work that must be done before disembarking seedlings:
- The vine can be both inside the structure and outside. In this case, the main stem of the plant must necessarily enter the closed zone, therefore, a hole is made in the lower part of the wall.
- Prepare the soil. For growing suitable fertile, loose, light soil mixture, which can be prepared from earth, sand, loam, peat, crushed chalk (at the rate of 90 grams for every second ten-liter bucket of soil) and mineral fertilizers.
In order for the plant to develop strong deep roots, it is recommended to pour the mixture into a prepared deep trench.
- Please note that the soil temperature indoors should be warmer than outside. The optimum temperature can be achieved with artificial heating.
- To protect the plant from indoor sunburn stretching the support wire system (in a horizontal position) at intervals of 20-30 cm. The upper wire is placed 35-40 cm below the ridge and at least 35 cm from the glass.
- Be sure to provide good drainage. If not, lay additional pipes.
Landing features
The technology for growing grapes in a greenhouse includes a number of rules:
- young bushes begin to be planted at the end of winter;
- the scheme for planting grapes in the greenhouse is as follows: a deep and wide hole is dug for planting (at least 35-40 cm). At the bottom of the hole in the center you can make a small embankment (as when planting an apple tree), place the seedling vertically in the center, straighten the roots, cover with earth, lightly tamp and water;
- before planting, it is advisable to apply organic fertilizers (compost, overripe manure).
- pay attention to the distance between seedlings, which should be at least 50-65 cm.The only way the vine will get enough free space for the development and formation of the main stem.
- do not forget to inspect the appearance of young bushes and roots before planting. The plant must be healthy and strong.
Pruning rules
After planting seedlings, you need pinch... Weak shoots are cut so that the plant does not expend energy on them during growth, but directs them to healthy branches.
Inflorescences with unripe flowers as needed should also be deleted... Pruning of sterile stems is carried out to the level of 5 leaves. For second-order shoots - up to the first leaf.
Over time, it is necessary to thin out the bunches. Using sharp scissors, they carefully cut off the inner berries, together with which various small particles are removed on the vines. Remember to manually pollinate the grapes... To do this, it is enough to slightly shake the branches with blossoming inflorescences.
In the fall, long branches are cut to the level of the initial bud, and the stems are cut to two-thirds of the entire length.
Watering and feeding
To get a good harvest for grapes needs proper care, follow the rules of fertilizing and watering the plant.
Watering features:
- The first watering is carried out immediately after planting.
- Then, to maintain optimal soil moisture, young bushes are watered once every 6-7 days.
- During the flowering period, watering is suspended, as well as during the formation of berries. Excessive moisture will negatively affect the quality of the crop.
- Please note that greenhouse grapes are not watered in the evening. An excess of moisture in the air will lead to cracking of the berries.
Fertilization:
- use nitrogen fertilizing with extreme caution;
- it is advisable to apply organic fertilizers before planting;
- during bud break, ammonium nitrate can be removed for good leaf development and bud formation, and before flowering - superphosphate;
- during further growth, only foliar fertilizers are applied. Superphosphate and ash are used after the end of the flowering period.
Wintering grapes
Before the onset of the first cold weather, the plant needs hide under cover (around mid-October).
To do this, the vines are tilted to the ground, covered with a dense layer of spruce branches and roofing material.
As a covering material, you can also use blankets, synthetic winterizer, sawdust.
If the greenhouse roof is removed, the plant can winter outdoors under the snow.
Problems with fruiting
Why not produce grapes in a greenhouse?
- lack of nutrients (zinc, manganese, boron) - start feeding properly plant;
- the opposite situation can also occur - an excess of nitrogenous fertilizers.
In this case the plant gives all its strength on the formation of greenery, bears fruit poorly or does not bear berries at all;
- affects the yield and pruning technology. Untimely thinning of vines leads to peas, not ripening of berries. It should also carry out off-season pruning.
Growing grapes in a greenhouse is a troublesome task that takes a lot of time and effort. But, the result is worth it... Proper preparation of the premises, adherence to planting technology and good care will allow you to get a quick, plentiful, tasty harvest!
Useful videos about growing grapes in a greenhouse:
Unfortunately, many grape varieties cannot be grown in northern climates, since the plant is too thermophilic. In such cases, they resort to using greenhouse structures. Indoors, the culture can be provided with no less care than in the southern regions.
Greenhouse growing rules in Siberia
For northern latitudes, growing grapes in greenhouses has many advantages.
Growing grapes in a greenhouse makes it possible for the fruit to ripen earlier.
The grapes that grow in the greenhouse are practically immune to insects.
The vineyard is protected from frost in the greenhouse.
By growing grapes in a greenhouse, you can achieve high yields.
A vineyard growing in a greenhouse does not need to be treated with chemicals.
It should be noted right away that it is unprofitable to build a greenhouse only for your own use of grapes, since too high costs are ahead.
As a rule, growers resort to the greenhouse method in the case of industrial use of the crop, that is, they grow grapes for sale fresh, or they are going to use the berries for mass processing for wine or other food products, with the subsequent sale of finished products.
It is noteworthy that not all varieties are suitable for growing inside closed soil.... In Siberia, Delight, December, Strashensky will not take root in such conditions.
Varieties
However, they will give excellent results the following cultures:
- Arcadia.
- Transparent.
- Laura.
- Song.
- Kishmish.
- Irinka.
- Currant.
- Alyoshenka.
- Sidlis.
It is characteristic that Arcadia is able to bear fruit and bring record harvests in greenhouses - productivity is an order of magnitude higher than under normal conditions.
The same performance can be expected from Transparent. Laura will delight you with larger berries than in open soil.
Types of greenhouses and planting
Usually, gardeners use two types of structures - a wall-mounted and a stationary type.
- The wall method involves the use of a wall of a heated residential building as one of the walls of the structure.... Thus, this wall provides additional heat and maintains an optimal level of heat transfer. It is noteworthy that, using this method, during the summer season, you need to open the structure and properly ventilate. As a rule, an earlier harvest can be expected in this case.
- The second method is a stationary structure, which is recommended to be built on the south side of the garden area to receive a large amount of light.... The size depends on the desired amount of planting material. The only requirement is height. The entire building must be more than two and a half meters in height. This is necessary so that the bushes of crops can grow as well as possible without creating crowding.
Features of preparation
The first condition is proper soil preparation.
It should be noted that the roots of the plant are located in the upper layer, so it is necessary to create the most suitable conditions for their strengthening and further development. The soil layer should be composed of soil, sand and gravel, with sand and gravel usually making up about half of the potting mix.
Top dressing
The mixed soil should be fertilized with mineral fertilizers.
For this, ready-made mineral complexes are chosen that have a beneficial effect on the development of the entire plant, participate in the formation of the green and woody part.
Technology
- It is advisable to mulch the soil and cover with a special agrofibre to prevent the growth of weeds, as well as to control the level of moisture and retain heat.
- Holes are made for cuttings.
- Usually plants planted in three rows, while the distance should be at least one and a half meters between plant units.
Planting care
Care measures consist of several points that must be strictly observed in order to obtain high results:
- watering;
- pruning;
- top dressing with saltpeter;
- feeding with phosphorus;
- maintaining a constant temperature;
- airing;
- humidity control;
- prevention against diseases.
Since at first the plant requires a lot of moisture to harden, it should be watered regularly, but do not overdo it.
Water only if drying of the soil is noticed. Over time, weak, dense or damaged vines are removed - you cannot provoke excessive density in order to avoid peas, reduce productivity.
- As soon as the first buds appear, the new plants are fed with a solution of saltpeter four times a month, that is, every week..
- Next, you should add phosphorus fertilizing.
- In this case, the varietal characteristics of the culture are taken into account - the most suitable feeding for this variety is selected. It is advisable to use a high-quality sprayer for this in order to apply the mixture to the branches as much as possible for normal absorption.
- After flowering, wood ash is added, since this agent acts not only as a fertilizer, but also serves as an excellent preventive measure against fungi.
Greenhouse growing rules in the Moscow region
Several facts speak in favor of growing grapes in a greenhouse.
In greenhouse conditions, in any weather, you can create a comfortable microclimate for the normal development of culture, since the minimum temperature regime can be only five degrees Celsius.
At the same time, an acceleration of the activity of all growth phases is noted, due to which the beginning of fruiting is shifted earlier by about a month. Among other things, a greenhouse is a reliable shelter from drafts, sudden gusts of wind, dangerous precipitation. Recommended varieties for the Moscow region:
- Korinka Russian;
- Michurinsky;
- Moscow Stable;
- Irinka;
- Rylines Pink;
- Rusball;
- Agat Donskoy;
- Kay Gray;
- Alpha;
- Northern Early.
As in Siberia, it is better to use seedless varieties for greenhouse cultivation.... In addition, it is recommended to plant crops that are overly attractive to birds. In closed ground, invasions of feathered pests are not terrible.
Types of greenhouses and planting
In the Moscow region, a wall-mounted version of a greenhouse with one transparent wall facing the south or south-west side is most often used for greater access of light.
However, they often build a stationary greenhouse equipped with water heating, a drip irrigation system, artificial lighting, and special shelving. Arched or domed design. For construction, a metal frame with a polycarbonate coating is used.
Dimensions (edit)
The height of the arch is at least three meters, the total area depends on the amount of planting material - the purpose of growing... Classic dimensions: height - three meters, area - thirty squares. Before construction, it is necessary to make a drawing design of the structure, which takes into account: half-arcs of the sides and gaps, vertical posts, fasteners, horizontal ribs, the location of the vents, doors.
Fill
Further actions include digging a trench for the foundation, establishing formwork, embankment for a sand cushion, reinforcement with steel mesh or wire, concrete pouring.
- It is noteworthy that even at the stage of pouring the foundation, it is worth fixing the frame racks. To do this, you can use pipes or metal corners.
- Distance between supports - 1 meter.
- After installing a solid frame, the surface is covered with polycarbonate.
Soil preparation
The first step is to prepare the soil for planting seedlings.
- First you need to decide on the location of the vine, that is, where it will be located - inside the greenhouse or outside, but regardless of where the vine will grow, the rhizome should only be in closed soil.
- The soil should be balanced with the addition of the necessary nutrients, while containing sufficient drainage mixture to filter air and water.
- Possible composition of the potting mix - earth, sand, loam, peat, chalk powder.
Landing
Young seedlings should be planted in February.
- Directly disembarking is carried out in the same way as on the open ground - hole with a diameter and depth of fifty centimeters, where top dressing is applied, fertile soil, a mound is formed on which the roots are straightened.
- Compost, manure, humus are introduced into the pit.
- The root zone is covered with mulch, watered abundantly.
- The distance between the novosads should not be less than fifty centimeters. Most often they are planted at a distance of seventy centimeters from each other, but this is in case there is a lot of free space for planting.
Care
Further care consists of systematic watering, eliminating weeds, sanitary pruning, preventive measures against fungal and other diseases.
But timely normalization of the brushes is also necessary, since the most comfortable conditions are created inside the greenhouse in order to provoke possible overloads.
The short Russian summer does not indulge in an abundance of sunny days, so the idea of planting grapes in a greenhouse seems quite logical and correct. Growing in greenhouses significantly increases the chances of getting a good harvest of grapes, but only if agricultural technology is followed.
Where is the best place to plant grapes outdoors or in a greenhouse?
In some regions of Russia, due to the peculiarities of the climate, it is simply useless to arrange vineyards in the open air, the berries do not have time to ripen until the end of the season. In such conditions, gardeners have no choice but to move heat-loving plants to the greenhouse. However, in the south, the greenhouse method is also used: local growers successfully grow super-early varieties and sell berries profitably at the very beginning of the season, making a solid profit. In heated greenhouses, the first crop can be harvested already in May-June!
The choice in favor of a greenhouse is worth making for the following reasons:
- grapes ripen much earlier than outdoors;
- you can plant various table varieties that are demanding on climatic conditions;
- plants are protected from frost in late spring, from severe frosts in winters with little snow, from hail in summer;
- the greenhouse allows you to avoid the fight against wasps and other pests, which means you do not have to use chemicals;
- it is more convenient to work with plants in such conditions, especially in winter and early spring;
- ripening berries do not crack due to precipitation;
- yield increases;
- grapes in taste and size are no worse than those grown in the fresh air.

On top of that, you can plant tulips, strawberries, radishes or greens in the greenhouse using the free space between the vines.
Where to start growing grapes in a greenhouse?
For planting indoors, it is better to take early and very early grape varieties. According to the experience of gardeners, good results are shown by: Timur, Queen of Vineyards, Early Gourmet, Prometheus, Super-Early Elegant, Arcadia, Victoria, Laura, Krasa Nikopol, Alladin, Moldova, Krasa Severa, Presentabil, Gift to Zaporozhye, Kesha-1.
Do not grow varieties with dense brushes in a greenhouse, since fungal diseases can damage them due to poor ventilation.Try to choose grapes with a loose brush (for example, Codryanka).
Prepared seedlings should be planted in rows, retreating from the walls of the greenhouse at least half a meter. There should be at least a meter between the rows, otherwise impassable thickets will turn out. In a small greenhouse, you can plant grapes in the northern corner and distribute their shoots horizontally along the wall so that the fruiting vines are directed upwards.
Landing is carried out at the end of February in the usual way, without any special features. The main thing to remember is that grapes need loose soil (you can mix loam with peat and sand, adding mineral fertilizer) and good drainage.
After placing grape seedlings, stretch the supporting wires along the walls of the greenhouse at intervals of 20-30 cm. The topmost wire should be located no closer than 35 cm from the glass, otherwise the plants will suffer from sunburn.
Features of caring for grapes growing in a greenhouse
In greenhouse conditions, the grapes will feel good only if the temperature is right. It should be increased gradually, starting from +10 degrees at the time of planting and up to +24 degrees by the budding period (+16 degrees will be enough for grapes at night). When the berries begin to set and ripen, temperatures up to +30 are allowed during the day. They control the temperature in the greenhouse using a slightly open window or arrange forced ventilation. And to protect from the hot summer sun, you can use a greenhouse shade net, which is sold in specialized stores.
Watering greenhouse grapes deserves special attention.:
- immediately after planting seedlings, the soil is thoroughly moistened;
- after a week, repeat abundant watering and mulch the earth with compost or mowed grass;
- throughout the summer, the vines are watered no more than once a week in hot weather, soaking the ground well with water;
- when the berries begin to ripen, watering should be carried out less frequently, avoiding waterlogging, otherwise the grapes will crack.
To prevent the berries from bursting due to waterlogged air, you should not water the plants in the evening, and at night it is useful to open the window on the leeward side.
Along with watering, it is convenient to apply fertilizers. First, greenhouse grapes are fed with potassium every two weeks, with the appearance of flowers, fertilizing becomes weekly and fizzles out by the time when the color of the berries begins to change. Nitrogen or a complete mineral fertilizer can come in handy if the vine is not growing well.
You need to pollinate the grapes manually, simply by hitting the stems or shaking them, although in some varieties you have to collect the pollen in the palm of your hand, gently tapping the flowers, and then transfer it to the pistils.
In order for the berries to receive more light and develop well, it is imperative to pinch the greenhouse grapes several times per season and remove unnecessary shoots, leaving the strongest, with the best inflorescences. Tie the selected stems to a wire and make sure that they grow in the right direction. Cut the lateral shoots of the second-order grapes to the first leaf, the sterile stems to the fifth leaf. By the end of the season, it is recommended to leave a couple of shoots near the top of the main stem so that excess juice goes into them. This will further help keep the grapes from cracking.

Do not forget to also thin out the bunches when the grapes are no larger than a pea (they pour quickly). Use scissors with long blades, removing the inner berries first and then the smallest ones. A distance of about 7-8 mm should remain between the berries, and it is desirable to leave more grapes at the top of the bunch. As the bunches ripen, it is necessary to periodically cut off the cracked or diseased berries.
In the fall, cut off the fruiting branches to one bud, the main stem by two-thirds. For the winter, it is enough to bend the vine and cover it with straw, or dry sawdust, old blankets, padding polyester or other permeable covering materials. If the roof of the greenhouse is removed, then the grapes winters well under the snow.
