What can be grown in one greenhouse at a time?

What greenhouses are needed?

In summer, lightweight film greenhouses are ideal. More solid option - unheated greenhouses covered with glass or polycarbonate. For year-round cultivation, capital greenhouses with a heating system are suitable. Joint planting of vegetables in a polycarbonate greenhouse, today, is considered the most practical.

When planting plants, you need to keep in mind that humidity and temperature requirements can be different.

For optimal soil moisture, drip irrigation is recommended. Most cultures prefers warm water, therefore, it is impossible to connect directly to the water supply system, a storage tank is needed in which the moisture will be warmed up.

In a year-round greenhouse, illumination is required. For vegetables that need bright light, additional fluorescent lamps will be required. It is very convenient if the design will have two input blocks at opposite ends constructions. This layout will help to accommodate crops with different temperature and humidity requirements and facilitate plant maintenance.

Pros and cons of sharing

Combining crops in one greenhouse has a number undoubted advantages... Among them:

• saving scarce space;
• opportunity reduce heating and lighting coststhat increase with the operation of several greenhouses;
• indoor soil is suitable for particularly capricious and demanding crops;
• drip irrigation system and vents makes it possible to individually adjust the temperature and humidity level.

Mixed plantings in the greenhouse, andhave some drawbacks:

• the possibility of cross-pollination;
• plants can be affected by pests typical of other crops;
• in small greenhouses, it is difficult to create conditions that are optimal for each type of vegetables;
• there is a risk of plant thickening.

What crops can be grown together?

What can be grown in one greenhouse at a time? Most often, one of the cultures is basic. Usually these are tomatoes or cucumbers, to which other vegetables are planted. Read about what is better to plant with tomatoes or cucumbers on our website.

The most difficult is considered a joint

placement of tomatoes and cucumbers

... The compatibility of vegetable crops when planting in a greenhouse is different, and the care requirements change accordingly.

Tomatoes cannot stand high humidity air, they need moderate watering, prefer mineral fertilizing based on potassium and phosphorus. Cucumbers need high humidity, they stop growing from lack of water, the fruits become small and bitter. As top dressing, organic matter is preferable: diluted mullein or bird droppings.

The location of vegetables in the greenhouse must be thought out in advance. If you plan to plant cucumbers and tomatoes in the same greenhouse, it is important to separate them in opposite directions... It is desirable that the blocks have separate entrances.If there is no second door, the cucumbers are planted in the warmest distant end. Tomatoes are located at the entrance vestibule, this will provide the coolness and fresh air necessary for vegetables.

How to distribute the plants in the greenhouse? In a small greenhouse, tomatoes and cucumbers can be divided by plywood partition, plastic or other material.

A thick curtain made of plastic film or a screen made of oilcloth stretched over a wooden frame will also help. Insulation will increase moisture levels in the cucumber zone, which will have a positive effect on the yield.

What else can you plant together in the same greenhouse? Next to tomatoes other nightshades can be planted: peppers and eggplants (read on our website an article on the compatibility of eggplants with other crops when planting in a greenhouse). They are more demanding on moisture, but they love fresh air no less than tomatoes. Feeding preferences for these crops are also similar.

It is also important to take into account the possibility of cross-pollination. Because of this danger, it is undesirable to place sweet and bitter peppers next to each other. After pollination sweet fruits will taste bitter, spicy ones will lose the piquancy of taste. You can check the compatibility of peppers with other cultures on the website.

What crops can be planted in the same greenhouse? Early ripening crops will become neighbors of vegetables with a long growing season: white cabbage, lettuce, herbs, green onions, radishes. These plants convenient to plant along the edge of the ridgesto harvest without disturbing cucumbers, tomatoes and eggplants. After digging up radishes or cutting cabbage, a new portion of seedlings can be planted in the vacant space.

Melons and gourds get along well with cucumbers: pumpkins,

watermelons, melons

... Planting of different varieties is possible

zucchini

, squash. Them

convenient to place on the sides of cucumber bushes planted in the center.

Spices not only increase the profitability of greenhouses, but also scare away pests... In this role, various types of parsley, celery, mint are especially effective. In contrast, green lettuce can attract naked slugs. Do not plant it next to varieties that are especially sensitive to pests.

Neighborhood (compatibility) of vegetables in the greenhouse: see tables for consideration below.

Greenhouse cohabitation: rules of care

Vegetables living in the same greenhouse need special care... The topsoil is replaced annually, before planting, the soil is spilled with a solution of copper sulfate or potassium permanganate. The soil is fertilized with humus, wood ash and a small dose of mineral fertilizer (superphosphate, potassium sulfate) are introduced into it.

If seedlings are grown in a greenhouse, for her it is better to select a separate area... When transplanting seedlings into a permanent home, it is important to make sure they are completely healthy.

If pest larvae or signs of disease are found seedlings need to be cured and only then move it to the greenhouse.

Early maturing hybrids are more suitable for joint placement. They are fruitful, disease resistant. For prevention young plantings are processed with a weak solution of potassium permanganate, during the growth of the planting they are sprayed with phytosporin or other non-toxic bio-preparations.

Plants planted in the same greenhouse can feel very good and not compromise yields. It is important to closely monitor their condition.to take timely action in case of problems. For the next year, you can make adjustments to the planting, taking into account the experience gained.

Let's figure out how to properly use all the greenhouse soil. To get a noble harvest, which will be ready for harvest earlier or will have time to ripen (applies to the northern regions), we plant vegetable crops in closed ground. Building a greenhouse takes a lot of effort, time and money, so I want to plant it as much as possible, and we often plant different crops close to each other.Vegetables that are improperly selected for joint growth can cause large losses in yield, so you need to know what you can plant with in the greenhouse. Generally, such heat-loving vegetables as peppers, tomatoes, cucumbers are grown in greenhouses. If there is room left, I would like to add something else. Many cultures are able to coexist peacefully, but there are also representatives who, by their presence, will inhibit the growth and development of the main “settlers”. We propose to consider which joint planting of vegetables in the greenhouse is permissible and which are not.

What is protected ground landing for?

Today, not a single summer cottage is complete without a greenhouse or greenhouse. Experienced gardeners argue that the harvest that is obtained from the greenhouse cannot be compared with that obtained from crops planted in the open field.

Many in greenhouses grow not only tomatoes and cucumbers, but also root crops, greens, ornamental flowering plants. Such plantings allow you to monitor soil moisture, regulate temperature for better crop growth. Many novice gardeners do not know that they can plant together in a greenhouse, and it so happens that their harvest is much poorer than that of a neighbor behind a fence who grows vegetables in ordinary beds. What's the matter? You just need to reasonably use the place of closed ground and not push everything that comes to hand into one area. We propose to figure out which vegetables can be planted in one greenhouse, and which are not recommended.

Cooking a greenhouse

Indoors, everything will grow ideally. In the spring, when the snow is still in places, it is already quite warm and good in the greenhouse, why will it stand idle if it is possible to get the first harvest of greenery in it? Moreover, many crops are ideal precursors for planting cucumbers and tomatoes. If you have plans to plant these particular vegetables, we suggest preparing the ground, and at the same time eating the very first vitamins of green crops from your own garden before anyone else!

So, before planting the main crops in the greenhouse, sprout lettuce, watercress, parsley, onions (per feather), dill, Beijing collard greenhouse, salad mustard in its soil. After harvesting, dig up the soil again, remove the remnants of the grown plants and you can start the main planting. The question of what can be planted in a greenhouse together is of interest to everyone, so you should think carefully before choosing vegetables.

For example, cucumbers with tomatoes will not grow very well together, since the crops need different temperatures. Eggplants generally do not like thickening and the proximity of other crops. But it is still possible to grow all these vegetables together, you just have to choose the right varieties and act. By following our recommendations, you will be able to achieve a high yield, even if your greenhouse is planted with different vegetables. What crops can be planted together? We suggest starting the selection of neighbors for tomatoes.

What can you plant tomatoes with in a greenhouse?

These vegetables love to grow in light, fertile soils saturated with calcium. It is necessary to produce stable fertilizing with calcium nitrate to increase yields. If the soil in the greenhouse is fertilized with organic matter, then additional fertilizing will not be useful, on the contrary, it can become detrimental to the crop. "Overfed" tomatoes will gain green mass, but they will give few fruits, and they will be small. Tomatoes need ventilation, moderate air temperature, abundant watering, which are done directly under the root. And with what can you plant tomatoes in a greenhouse? What cultures will they take root with?

You can plant an early variety of white cabbage nearby. Express, Ultra-early Miracle, Nakhodka will do. "At the feet" of the ridge, head and leafy salads will grow well. Sugar giant radishes, parsley and onions are also good neighbors.Unfortunately, tomatoes cannot create a good union with fennel and dill, so give up such a neighborhood.

Many gardeners make a gross mistake by creating joint plantings of cucumbers and tomatoes in a greenhouse. If you do not have a separate space for cucumbers, then do not plant crops on one bed, plant on different ones, and, which will be ideal, separate the plantings from each other with a bed of pepper. Planting tomatoes and hot peppers in the same greenhouse is unacceptable only if you are not a gourmet and you are not embarrassed by the bitter-sharp taste of tomatoes, the bush of which can get dusty with a burning neighbor.

Before looking for neighbors for cucumbers, we suggest that you find out when you can plant cucumbers in a greenhouse with seeds.

Cucumber planting rules

When to plant seeds depends on the growing region and the greenhouse. If there is no artificial lighting and heating in it, then residents of the central and northern parts of Russia can start planting in mid and late May, when the outside air temperature reaches +15 degrees. If you live in the southern part, then you can plant cucumber seeds in a greenhouse in April. The same period is relevant for greenhouses with heating and lighting.

Seeds must be prepared two days before planting. To do this, place them in the refrigerator or any other cool place for 24 hours. After the time has elapsed, prepare gauze bags, place one seed in each, put in water for 12 hours. After that, take out, leave the seed bags at room temperature, by the next day small sprouts will appear. If some seeds have not hatched, this will mean that they are empty and you can throw them away.

What can you plant cucumbers with in a greenhouse?

Planting seeds should be done in a one-line or two-line method. At the same time, there should be trellises on the garden bed, to which it is necessary to tie up the plants for their good fruiting. Cucumbers need abundant watering, if the culture lacks moisture, then the fruits may have a bitter taste. In addition, you need to consistently produce organic and mineral supplements. Cucumbers respond well to solutions of potassium sulfate, bird droppings and superphosphate. What can you plant cucumbers with in a greenhouse?

If the cucumbers grow not just tied up, but there is a trellis, then they will not damage with their antennae nearby crops that they can catch on. If there is enough space between the bushes, then you can plant white cabbage. Also excellent neighbors will be dill, parsley, fennel, basil, cabbage and leafy salads, Siberian early maturing eggplant and the Dream of a mushroom picker, radish. Peppers and cucumbers can be planted together in a greenhouse, but the neighborhood of tomatoes is undesirable and possible only if the ridge with them is fenced with another crop. Corn grows well next to cucumbers, they can coexist both in different and in the same garden. The only thing that may need additional processing of plants for fruit set.

Planting pepper

Sweet peppers are grown by many gardeners. It is ideal for fresh consumption, endowed with a pleasant taste and aroma, contains many vitamins, perfectly complements a salad of fresh vegetables. Also, pepper is used for preparations for the winter, there is nothing better than opening a fragrant jar with lecho, made from peppers grown on our own plot, on a frosty day.

This crop can be planted in a checkerboard pattern, it is quite calm about the thickening of the planting and shade, so feel free to plant seven plants per square meter. The denser the planting, the richer the harvest! Mineral and organic fertilizing is needed, stable ventilation of the greenhouse, good watering. So, what can you plant peppers with in a greenhouse?

Peppers go well with eggplants, since both crops are nightshade.But too close the location of plants from each other can be the reason for a decrease in the yield of both. We said that you can plant tomatoes and peppers in a greenhouse, they grow well next to each other. If you have a desire to place eggplants in the greenhouse, arrange the beds in this order: eggplants - tomatoes - peppers. Onions, lovage and basil will also not harm the peppers and will thrive themselves. Joint planting of cucumbers in a greenhouse with peppers can be done quite calmly, these cultures are friendly.

Eggplant

Many vegetable growers grow eggplants. The best option for planting a crop is in a greenhouse. In protected ground, the plant will develop faster, more ovaries will appear, respectively, and fruits. Growing in a greenhouse, eggplants will yield a greater yield than when grown in an open area. The plant loves moisture, sunshine, high-quality feeding. Fertilizers should be alternated. At the first stages of development, organic matter is needed, at the stage of fruit ovary, mineral fertilizers, more calcium and potassium are needed. Do not plant the plants too densely, the yield will decrease significantly due to lack of sun, eggplants do not like crowding.

With what can you plant eggplants in a greenhouse if they are so capricious? Of course, co-cultivation is difficult, but still possible. We already wrote that the culture gets along well with peppers and tomatoes. If the peppers should be a little further away, fenced off by another ridge, then the tomatoes should also be planted according to plan. First, there should be space between the eggplant and tomato beds to allow as much extra light as possible. Secondly, when planting tomatoes next to eggplants, choose a low-growing variety. If the tomatoes are tall, they will shade the eggplants, and they will grow small, and the bushes will be weak.

Onions will grow well next to eggplants and will not harm their capricious neighbor. You can also plant a melon, it will also grow well in a greenhouse, it will not shade the eggplants, and will not interfere with their growth.

We suggest continuing the review of what you can plant with in the greenhouse. Let's move on to greens, which they love to grow indoors. The thing is that in this way you can have fresh, young salad, dill, onions (feathers) on the table all season, because with proper planting, it is possible to collect several harvests per year.

Salad

This crop needs soil saturated with organic fertilizers. It is recommended to plant in rows, the distance between which will be on average twenty centimeters, this is necessary for the correct formation of the bushes. If you plant seeds every two weeks, then the yield will be stable and you will be able to have fresh salad greens until the end of the season. The culture is very fond of good moisture, loose soil, stable fertilization. What can be planted in the same greenhouse with a salad?

If you have plans to have a greenhouse in which only greens will grow, you can plant dill, parsley, basil, onions and on feathers, cabbage and leafy salads - all this is in perfect harmony with each other. The only thing is that the onions need to be planted on a separate bed if you want to get onions, because a lot of space is needed to form the heads.

Cabbage, both leafy and cabbage, will grow well with the salad. The salad can be planted between bushes of cucumbers, tomatoes and peppers. Eggplant will also be convenient to coexist with salad. By planting these crops together, you will get rid of unnecessary hassle. That is, by fertilizing and watering tomatoes, cucumbers, peppers and eggplants, you will immediately carry out the necessary procedures for the salad. All these crops love moisture, loose soil, top dressing.

Unwanted co-cultivation

We wrote that it is possible to combine tomatoes and cucumbers in one greenhouse, but subject to certain rules.We have already told you what to plant with what in a greenhouse, and which crops cannot be combined, but what to do if you have greenhouses worth its weight in gold, and you want to plant both cucumbers and tomatoes? Growing them together is not recommended, but you can still try. Take advantage of further tips and you will not lose your harvest.

The first thing every vegetable grower should remember is that cucumbers, unlike tomatoes, do not like airing, they are too susceptible to infections, these gentle creatures love warmth, no drafts, and if you do not follow the rules, there will be a lot of barren flowers, foliage will begin to turn yellow.

Cucumbers require greenhouse conditions for high-quality growth, a lot of water. And tomatoes can't stand that. They need fresh air, too moist soil can cause rot in the roots, fungal diseases, which not only adversely affect the harvest, but can completely ruin the plants. Of course, planting in separate beds is permissible, but what to do with airing?

You can plant tomatoes closer to the exit, and place cucumbers in the distant beds. If they are planted at the end, then it will be possible to make a fence, for this you need a film. Attach it to the ceiling to create a curtain, take a wooden stick and attach it to the bottom of the film, wrapping and fixing. Now you can lift this curtain to go to the cucumbers and carry out all the necessary procedures, and they will be fenced from tomatoes, and when ventilating the draft, the fence will not lift, since it is weighted with a stick. Cucumbers will grow quietly in their "greenhouse", without interfering with the tomatoes, without sharing their warmth and moisture with them, and you use the whole place of the greenhouse, plant all the necessary crops, and the yield will be high, since all conditions have been created for tomatoes and cucumbers. good growth.

Hot peppers are by no means planted in the same greenhouse with other crops. You can not make a joint planting, even with sweet peppers. With over-pollination, which will surely occur, the taste of tomatoes, cucumbers, peppers will be sharp, there may even be a burning sensation characteristic of hot peppers. Thus, you will simply spoil the taste of the entire greenhouse crop. For such a "hot" plant, create a small greenhouse in which it will be away from other crops.

It is worth remembering that planting asparagus beans next to them will help increase the productivity of tomatoes, but peas are completely contraindicated for them. Cucumbers will not be able to coexist with sage, it oppresses the plant and causes low yield. Now we propose to move on to considering the question of what to do if you want to grow root crops or melons.

A little more about joint landings

As mentioned earlier, so that the greenhouse does not stand idle in the spring, you can plant various greens in it, and after harvesting it, plant the main crops. We offer you another option. In April, early ripening beet varieties can be planted in the greenhouse. When the time comes to plant tomatoes, the roots will already grow well, place the seedlings calmly between them. Together, these cultures will grow excellently, will not interfere with each other. When the tomato seedlings have grown to such an extent that they shade the beets, the roots can be harvested and ready to be harvested. Thus, you can get early beets, and the greenhouse area will be used as much as possible. After harvesting root crops, you can again "refine" the vacated areas by planting lettuce, dill and parsley, and you will again win.

Well in the greenhouse, together with tomatoes, watermelons and melons will grow. Melons can be planted and mixed with tomatoes, and on a separate bed. The second option is more acceptable, since melons and watermelons are not very fond of drafts, but they also do not need the greenhouse effect, like cucumbers.Plant a crop simply on a remote garden bed or along the walls of the greenhouse behind bushes of tomatoes, watermelons and melons love a lot of sunlight. Planting melons for tomatoes is useful in that they attract more bees for pollination with their smell, insects, having arrived at the sweet aroma, will also take care of tomatoes. Watermelons ripen no faster than many varieties of tomatoes, harvesting is done on average ninety days after planting the seedlings. Thus, the greenhouse will be fully operational throughout the entire season.

We learned what to plant with in the greenhouse and what combinations to avoid. But for the quality of the crop, it is necessary to properly prepare the closed ground, it depends on how well all the crops planted in the greenhouse will grow.

Preparing the greenhouse for the season

Vegetables planted indoors, unlike those that grow outdoors, practically do not receive nutrients from the external environment, so it is worth taking care of the condition and maintenance of the soil in advance. In addition to regular feeding, cultivated plants need high-quality soil that will meet all the requirements - good air permeability, absorbency, light composition.

If the site is stably used for the installation of a greenhouse, then the soil is already depleted and cannot provide all the nutrients to the plants. The best option is to completely change the soil by removing the old one from the greenhouse and placing a new one. If this is not possible, then enrichment measures can be taken, for this, apply as much organic matter and mineral fertilizers as possible two weeks before planting the plants.

In addition to fertilizers, the soil needs disinfection, because pathogenic bacteria and spores of fungal diseases could remain in it from last year's crops.

If the greenhouse is being built on the site for the first time, it is worthwhile to correctly divide the zone into beds. Any length is possible, but the width should not be more than 90 centimeters. They can be elevated (35-40 centimeters above the ground) or flush with the ground. The soil should be mixed with peat, manure, a complex of minerals.

Having learned how to use every centimeter of greenhouse soil correctly, you will increase the yield and save the territory of the site.

It's no secret that the climate in most of Russia is harsh. However, this does not stop our gardeners, because vegetables from their beds are tastier and much healthier than store vegetables. And in order to get record harvests not only in the south of the country, but also in the Urals and Siberia, we grow many crops in greenhouses.

Due to the large labor costs for the construction of greenhouse and greenhouse structures, every centimeter of this land is valued by gardeners worth its weight in gold, and here it is very important not to allow agrotechnical mistakes.

Variety matters, so when choosing plants for your greenhouse, pay attention to the varietal characteristics. Losing sight of varietal compatibility is the first mistake gardeners make. There is a widespread belief that if a tomato is suitable for open ground, then it will grow well indoors. This is completely wrong, because breeders test and breed varieties for certain conditions.

For example, a street tomato in a greenhouse can be affected by diseases (it can get sick and infect its neighbors), stretch out pretty much and build up a large amount of green mass, while not giving a good harvest. It's the same with cucumber: don't experiment with bee-pollinated hybrids in greenhouse conditions. And in general, I recommend planting only superbeam hybrids in greenhouses.

The second mistake is the wrong selection of crops when forming ridges. After all, plants are like people, if a person is surrounded by a good company, then everything goes well in life.Often, competent joint planting can significantly increase yields, simplify caring for them, and to some extent create protection against diseases and pests.

Now let's talk about specifics. The main crops in greenhouses are rightfully considered cucumbers, tomatoes, peppers and eggplants. It is these four vegetables that we most often plant in greenhouses and greenhouses. But, as they say, a holy place is never empty! Few gardeners can resist taking the last free corner. The whole earth must be in action! So hands are reaching out to plant a neighbor for tomatoes or peppers. And it's good if it is harmless radish or salad that can peacefully coexist with any garden plants. But there are also more serious crops that suppress their neighbors in the garden. So settling in is not always a good thing.

Indoor ground is a limited space in every sense. So you have to think twice before planting this or that vegetable in a greenhouse or greenhouse. And sometimes even abandon some cultures, because there may not be enough space for everyone.

Greenhouse tomato compatibility

A moderate air temperature is suitable for the growth of this culture. The tomato loves when the greenhouse is well ventilated, loves fertilizers. Plants need to be watered often, but only at the root. In a company with tomatoes, you can plant early white cabbage, for example * Miracle ultra early F1 ', ‘Express Fl’ ‘Nakhodka’. Its seedlings can be planted in mid-April and at the very beginning of summer you can get heads of juicy, crispy, sweetish cabbage for the first vitamin salads - such a neighborhood will not hurt at all, and the harvest will delight.

At the feet of tomatoes, you can place varieties of leafy or head lettuce, a good mixture of varieties ‘Bright vitamins’. Quite good companions are onions (if you grow them for feathers) and parsley (for herbs). You can also plant a watermelon in a company with a tomato. But when planting a tomato with green crops together, remember that he does not like the neighborhood with dill and fennel!

By the way, such a familiar greenhouse tandem as tomatoes and cucumbers does not bode well in fact. So, growing them in one greenhouse, it is advisable to spread the plants either to different beds (on the one hand tomatoes, on the other - cucumbers), or - if this is not possible - plant them in different corners and divide the planting with a couple of rows of peppers.

Greenhouse cucumber compatibility

It is possible to do any planting next to cucumbers only if you grow them on a trellis. Then the cucumbers will be comfortable, and there is plenty of room for the neighbors.

You can plant any green crops (dill, parsley, basil, fennel and others), leafy and head salads. Also, if a cucumber has enough free space at the legs, you can plant white cabbage there - such a neighborhood will not bring any harm.

A very strange, but very successful neighborhood of cucumber and radish. Of course, few gardeners would think of growing this root crop in a greenhouse, but the fact remains: such a partnership helps protect cucumbers from leaf beetles and spider mites.

Greenhouse Pepper Compatibility

All nightshades (tomatoes, eggplants, peppers) get along well, but for

for the best harvest, they should still be spread to different parts of the greenhouse or sown in separate groups. As for plants from other families, basil and lovage can be safely planted next to peppers (both hot and sweet). There will be no harm from these crops. Also a good companion is the bow.

Eggplant

Eggplant compatibility in a greenhouse Eggplants are very compact plants, so it is best not to add anyone to them, so as not to thicken or shade them. But if the place is worth its weight in gold, then this vegetable crop will get along well with onions. You can also plant a melon nearby.Neighborhood with tomatoes and eggplants is also not contraindicated.

Let's be friends!

Gardeners who have only one greenhouse in use have a desire to plant a variety of crops in it.

With the right selection, one greenhouse can accommodate up to 10 different types of crops.

It is important to think about the order of planting in advance so that the vegetables can feel comfortable. For each plant, it is required to create the most optimal conditions for development.

If you make the right selection, then in one greenhouse you can place from 5 to 10 types of vegetables and other plants. Consider below the compatibility of vegetable crops when planting in a greenhouse.

back to contents ↑ What greenhouses are needed?

In summer, the ideal option would be to use lightweight film greenhouses. More solid structures include an unheated greenhouse, which is covered with polycarbonate or glass. For cultivation all year round, they use capital greenhouses with a heating system. Planting vegetables together in a greenhouse covered with polycarbonate is the most practical option.

When planting plants, you need to be aware that the requirements for temperature and humidity parameters may vary.

Drip irrigation of the soil is able to provide optimal soil moisture. A large number of crops prefer only warm water, which makes direct connection to the water supply impossible. It is required to use a storage tank where moisture will be warmed.

For a year-round greenhouse, it is important to use backlighting. Additional fluorescent lamps are used for vegetables that need bright light. A design with two inlet blocks from opposite ends of the structure is considered convenient. Such a layout will provide the ability to accommodate crops that have different requirements for air humidity and temperature, which greatly facilitates plant care.

back to contents ↑ Advantages and disadvantages of co-location

Combining crops will help ensure a rational placement of vegetables in the greenhouse. The following advantages are highlighted:

1. Saving scarce space.
2. The system of vents and drip irrigation provides individual regulation of the level of humidity and temperature.
3. Indoor ground is suitable for demanding and particularly capricious crops.
4. Reduced lighting and heating costs that increase when using multiple greenhouses.

Mixed greenhouse plantings have some disadvantages:

1. There is a danger in planting thickening.
2. The likelihood of cross-pollination.
3. In a small greenhouse, it is difficult to create conditions that are optimal for all types of vegetables.
4. Plants can be affected by those pests that will be typical for other crops.

back to contents ↑ What crops are allowed to be grown together?

If we consider the compatibility of plants in a polycarbonate greenhouse, then one crop stands out, which becomes the base one. Usually, cucumbers or tomatoes are isolated as a base culture, and other vegetables are already planted with them.

Good and bad companions of vegetables:

The most difficult option is the joint placement of cucumbers and tomatoes. These vegetables have different compatibility when planted in a greenhouse, which changes the requirements for work.

Tomatoes simply cannot stand high humidity. They require moderate watering, preferably with mineral supplements based on phosphorus and potassium. Cucumbers need high humidity. If there is a lack of water, then they stop growing, and the fruits become bitter and small. In the form of dressings, organic matter is used: bird droppings or diluted mullein.

It is necessary to think in advance about the location of vegetables in the greenhouse. When planning to grow tomatoes and cucumbers in the same greenhouse, you need to breed them on opposite sides. These blocks must have separate inputs. If there is no second door, then the cucumbers are planted in the warmest far end. Tomatoes should be placed at the entrance vestibule to create fresh air and coolness for vegetables.

A mixed planting of crops in one greenhouse must be thought out in advance, having previously studied the neighborhood of plants.

To distribute plants in the greenhouse, such as tomatoes and cucumbers in the same greenhouse, a plastic or plywood partition is constructed.

A thick curtain made from a screen made of oilcloth or plastic film, which is pulled over a wooden frame, can help. With the help of insulation, the moisture level in the cucumber growing zone increases, which will have an excellent effect on the yield.

Along with tomatoes, other types of nightshade can be grown: eggplants and peppers. They are very demanding on moisture, and they love fresh air no less than tomatoes. Top dressing for these crops is similar.

It is important to know about the possibility of cross-pollination. Therefore, bitter and sweet peppers are not placed nearby. If cross-pollination occurs, then sweet fruits will taste bitter, and in spicy ones, the piquancy of taste will disappear.

Vegetables with a long growing season can be placed next to early maturing crops: radishes, cabbage, green onions, herbs, lettuce. These plants are conveniently placed at the edge of the ridges so that eggplants, tomatoes and cucumbers are not disturbed during harvesting. After cutting the cabbage and digging up the radish, new seedlings can be added to the vacated places.

Together with cucumbers in a greenhouse, it is good to grow melons, watermelons, pumpkins. You can plant different varieties of squash and zucchini. They are conveniently placed on the sides of the cucumber bushes located in the center.

Growing herbs not only increases the profitability of the greenhouse, but also helps repel insect pests. Various types of parsley, mint, celery are especially effective in this role. Naked slugs can be attracted to green salad. It makes no sense to grow it next to particularly sensitive varieties to pests.

Vegetables that live in the same greenhouse require special care. Replacement of the topsoil is carried out annually. It is necessary to spill the soil with a solution of potassium permanganate or copper sulfate before planting. Fertilize the soil with humus, make wood ash and a small dose of mineral fertilizer (potassium, sulfate, superphosphate) for it.

To grow seedlings in a greenhouse, you should immediately select a separate area. When transplanting seedlings to a permanent place, it is necessary to check that they are completely healthy.

If larvae of pests or various signs of disease are found, then the seedlings are first treated and then moved to the greenhouse.

Early maturing hybrids are suitable for joint placement. They are distinguished by their yield and disease resistance. Young plantings can be treated for prophylaxis with a weak solution of potassium permanganate. During the increase in planting, spraying with phytosporin or other non-toxic types of bio-preparations is performed.

Plants growing in the same greenhouse may not reduce yields and may feel good. You need to carefully monitor their condition, and if problems arise, then take action in time. Based on the experience gained, adjustments can be made for the next year.
