What plants will grow well after tomatoes? Can I plant tomatoes, cucumbers, cabbage or peppers?

This vegetable requires a mandatory change of location; it is important to choose the right new predecessor, since not all plants can grow well after each other. The process of changing the location of vegetable plants is called crop rotation; this term is relevant both on large agricultural lands and on small plots of amateur vegetable growers.

Since some plants leave behind diseases and pests in the soil, while others draw more beneficial microelements from the soil, thereby depleting it, you need to take into account what grew at the planting site earlier.

Since cucumber seedlings grow better in a greenhouse, they mainly alternate with tomatoes. But is it possible to plant cucumbers after tomatoes?

Video: What can you plant after tomatoes?

As the experience of many farmers and agronomists shows, yes. It is possible to grow loaches in a greenhouse in which Solanaceae were previously grown.

Tomatoes acidify the soil well, and this is completely harmless to cucumbers. Cucumber seedlings are well accepted and give a good harvest if compost is added to the soil, the predecessors of which were Solanaceae.

Cucumbers are planted after tomatoes

Cucumbers are not related to tomatoes, therefore they do not have common diseases with them and are quite suitable for growing the next year after tomatoes. One has only to take into account that cucumbers are sensitive to the nutritional value of the soil and require fertilization. Compost is best suited for these purposes.

It is good to plant cucumbers after tomatoes, because they are not susceptible to the diseases that attack Solanaceae (for example, late blight). The only thing that can damage both crops together is fungal diseases that develop in long-stagnant soil.

After the tomatoes, you can plant cucumbers in the greenhouse

We can say about cucumbers and tomatoes that they are “friends”. They can be grown either after each other or within the same greenhouse. To do this, it is better to divide the planting area into two parts and alternate these two crops annually. At the end of each season, the soil in the greenhouse is thoroughly disinfected to prevent fungal diseases.

After what crops are cucumbers planted?

Excellent predecessors of cucumbers will be plants that enrich the soil with substances necessary for the development of cucumbers: all types of cabbage, since this plant belongs to the cruciferous family and does not leave behind pathogens that are dangerous for cucumbers, and also loosens the soil well. legumes and peas will make the soil more fertile by enriching it with nitrogen. representatives of the nightshade family, which, in addition to tomatoes, include peppers, physalis, eggplant, and potatoes. onions and garlic, which are universal precursors for all plants except themselves.

When to plant seedlings of tomatoes, peppers and cucumbers in a greenhouse

Most summer residents prefer to grow tomatoes, peppers and cucumbers in a greenhouse. The fact is that these crops are quite heat-loving, and this method allows you to harvest a much larger harvest than when growing them in open ground

When planting seedlings in a greenhouse, factors such as weather conditions and soil warming, the age of the plants and their general condition are important.

When to plant seedlings of peppers and tomatoes in a greenhouse

Seedlings of tomatoes and peppers should be planted in a greenhouse at the end of April-beginning of May, but this applies to Central Russia, which includes Moscow and the Moscow region, in the Urals and Siberia the optimal time for planting is the end of May-beginning of June, in St. Petersburg - the end of May . There is no exact date for transplantation, as it depends solely on weather conditions. If the threat of frost has passed, the soil temperature is above +10 degrees, and the seedlings reach a height of 25-30 centimeters, each plant has more than eight well-developed leaves and at least two inflorescences, then the time for planting has come.

How to plant tomato seedlings in closed ground

You can choose any scheme for planting seedlings in a greenhouse, but you need to take into account that for plants to develop well, they need sufficient lighting and a lot of air, so you should not thicken the plantings. In the greenhouse, make small beds 30 centimeters high, dig holes 20 cm deep in each bed at a distance of 40 cm. Water the holes with a warm, weak solution of potassium permanganate at the rate of one liter per hole (this will protect the plants during the adaptation period from contracting diseases such as root rot, black leg, late blight, etc.). Two or three days before planting, tear off all yellow and cotyledon leaves from the seedlings, being careful not to injure the stems. Start planting in the afternoon after watering the tomatoes. Carefully remove the seedlings from the pots without destroying the earthen ball, immerse them in the holes, sprinkle with earth and tamp lightly. Water each tomato at the root with warm water (two liras per plant). Remember, if the plants have not outgrown, then you need to transplant them into the greenhouse so that the seedlings stand strictly vertically, but overgrown plants require a special approach.

How to plant overgrown tomato seedlings in a greenhouse

If the seedlings are from 50 to 70 centimeters in height, then in this case it is better to do this: dig holes 30 centimeters deep, place the plants in them and lightly sprinkle them, that is, do not completely bury the holes. After a couple of weeks, when the plants have taken root, cover the holes completely with soil. If the seedlings are about a meter high or a little lower, then in this case the seedlings need to be planted so that only the 30-centimeter tops peek out from the ground. A couple of days before transplanting, remove diseased and yellow leaves from tomatoes. In the greenhouse, make holes at an angle of 45 degrees, and from them make shallow grooves equal to the bare part of the seedling stems. Transplant the seedlings into the holes, bend their stems and bury them in the grooves. Using wire, make supports for the tops of the tomatoes, install them and secure the plants. Remember, during the entire growing period, tomatoes planted in this way must not be loosened or hilled. If the stems are exposed when watering, mulch these places with a small layer of peat.

Soil fatigue

Growing the same plants in one place usually leads to a reduction in yield and a deterioration in its quality. It happens:

• Due to soil depletion, since each crop consumes the microelements it needs from the soil, even the introduction of additional mineral fertilizers is not always able to correct the situation.
• Due to the fact that toxins released by plants accumulate in the soil and negatively affect the growth of some subsequent crops.
• Due to pathogenic bacteria and pests that accumulate in the soil, characteristic of a certain type of plant. The most striking example is late blight, the pathogens of which persist in the soil for up to six years and infect initially healthy planting material.

To avoid soil depletion, it is necessary to take into account such features of the plants being grown as the type of their root system, belonging to a certain family, which are necessary for the full development of the substance.

Basic concepts and principles

If different crops have approximately the same mineral composition (or even one mineral), then, naturally, each of the crops will deplete the soil of precisely this mineral. And the subsequent culture will feel very uncomfortable.

about cucumbers, I simply say that it is good to plant beans or legumes, and accordingly, after beans and legumes, cucumbers grow well. You definitely shouldn’t plant tomatoes after eggplants.

Therefore, it is advisable to sow green manure legumes after harvesting tomatoes. In the spring, mow the grass for green fertilizer, make holes in the beds and plant the next batch of tomatoes.

• Taking these two rules into account, we will create a priority list for tomatoes.
• Tomatoes can also be planted after beets. Before planting tomatoes, you need to prepare the soil well, that is, it needs to be fertilized. Peat and humus are suitable as soil amendments.
• Dividing plants according to their level of nutrient needs:

Beginning summer residents do not always know what to plant after beets or other vegetable crops to obtain a good harvest every year. How long can it take to grow other vegetables and which ones exactly after the beets have been harvested? Not everyone is familiar with the intricacies of organizing plantings on a plot, so amateur gardeners more than once encounter such problems as lack of harvest or low-quality fruits.

Planting in a greenhouse

A characteristic feature of growing tomatoes is the use of stationary premises. Such greenhouses create a favorable climate for the growth and development of this crop, increasing fertility and reducing harvest time. With properly organized ventilation and heating systems, you can harvest tomatoes until late autumn, and in some cases, all winter. However, this option also has negative sides.

First of all, we are talking about soil depletion. This process occurs much faster in greenhouse conditions than in open ground, because the earth is isolated from external influences. Gradually, nutrients and microelements become deficient, so plants need regulatory feeding.

The second danger when growing tomatoes in a greenhouse is the accumulation of harmful bacteria and fungal spores. In a confined space, even after pre-treatment of the soil, there is a risk of tomato infection with late blight and other characteristic diseases. In the favorable humid “climate” of the greenhouse, spread occurs faster and the plants may no longer be saved. Simple recipes can come to the rescue, as well as regular activities that help avoid illnesses.

In the video - what can be planted after tomatoes:

Basic rules for using a greenhouse:

• The soil for greenhouses must be treated against pests and disinfected so that bacteria do not get inside. The most commonly used method is the thermal method (calcination of the earth at high temperatures) and the use of disinfectant solutions.

The internal surface of the structure must be protected from corrosion and also treated with an antiseptic. At the beginning and end of each season, it is advisable to repeat the treatment, replacing worn parts if necessary.

Good ventilation is a must! This will help prevent the spread of harmful bacteria and mold, and will also ensure the circulation of oxygen necessary for plants.

To prevent harmful substances from accumulating in the greenhouse, it is recommended to completely renew the soil approximately every 5 to 7 years. Such activities are undoubtedly labor-intensive, but they are fully justified.

To prevent plants from getting sick, it is recommended to alternate planting tomatoes with herbs, parsley, onions and beans. You can plant lettuce, radishes and spinach early and late in the season to make the most of your greenhouse space. These crops are characterized by early ripening, so they will not interfere with tomatoes.

The use of fertilizers must be strictly dosed and not exceed the specified standards. In a greenhouse, there is a danger of accumulation of harmful organic compounds that cannot be absorbed into the soil, as in open ground. That is why small, frequent portions are used to fertilize tomatoes.

To ensure a high-quality harvest, after tomatoes it is best to plant plants of the cruciferous, legume and legume families. An exception would be peas, which will not bear fruit well after tomatoes.

If you plan to use the greenhouse exclusively for growing tomatoes and do not want to use the principles of agricultural technology, you can use the following tips. First of all, regularly check the acidity of the soil, which becomes acidic where tomatoes are constantly growing. This leads to a drop in yields, so additional liming of the land is used. The second important point is the need for periodic rest.

But when to start growing cucumber seedlings, and how to set a time frame for growing, this information will help you understand.

This information will help you understand which varieties of tomatoes for the Urals should be used in a greenhouse first.

It is not at all necessary to leave the greenhouse empty for the entire season; it is enough to plant green manure in the winter and then dig them up along with the roots. Plants from the legume family, cereals and cruciferous crops are well suited for these purposes.

After what crops should cucumbers not be planted?

Plants of the same type should not be used when alternating plants in the garden. Therefore, undesirable options include:

• pumpkins
• zucchini
• watermelons
• melons

All these plants are susceptible to the same diseases as cucumbers, suffer from the same pests and need the same microelements, so their continuous cultivation in the same bed will reduce soil fertility and crop yield.

IMPORTANT : At the end of each season, the soil in the greenhouse is thoroughly disinfected to prevent fungal diseases.

Proper crop rotation, taking into account the characteristics of each type of plant, will help you harvest a good harvest even in a small greenhouse. We can say about cucumbers and tomatoes that they are “friends”. They can be grown one after another, the fruits will grow large and juicy.

In what container should I start growing seedlings?

It is very convenient to take disposable containers with a lid and grow seedlings in them, just before doing this, make holes in the bottom to drain excess water. Place these containers on a tray to prevent water from dripping onto the windowsill and to make them easy to carry. Condensation from the lids of the container will need to be wiped off.

Some people use peat pots. If you do this too, then wrap the peat pot in film so that the moisture does not evaporate. And it should also be taken into account that modern peat cups are often made not from peat, which decomposes in the ground, but from pressed cardboard, which does not dissolve in the soil for a very long time. The pots have to be torn apart before planting, which means they do not fulfill their function of preserving the root system intact, and this, in turn, retards the growth of plants.

The next method of sowing seeds for seedlings is sowing in peat tablets. For this method of growing seedlings, they are soaked in a small amount of water. The tablets swell, absorbing water, and after that seeds are sown in them. All small seeds (petunia, strawberries) are sown on the surface. Large seeds (tomato, pepper) are placed in a small depression in this peat tablet. For small seeds use small peat tablets, for large seeds - large ones. Sow one seed per tablet. The mesh around the peat tablet must be removed. As soon as the roots of the plant appear, you need to immediately plant it in a large container, adding prepared soil around the peat tablet.

It is also convenient to use plastic seedling cassettes for growing seedlings. Just don’t try to grow seedlings in cassettes before planting them in the ground. The roots in the cassette will intertwine and become entangled, and when transplanted, the plant will spend some more time restoring the root system. Therefore, when the seedlings have produced several true leaves, they are transplanted into larger pots. Another option is to buy very large plastic cassettes and replant them in the ground while the plants are still growing.

What not to plant after tomatoes

Tomatoes are bad predecessors for the following vegetable and garden crops:

• potatoes;
• physalis;
• all varieties of pepper;
• tobacco;
• eggplant;
• strawberries;
• strawberries

All of these crops are susceptible to the same diseases as tomatoes, and they can also be damaged by the same insect pests. therefore, all of the above plants may suffer from:

• late blight;
• rot;
• wireworm;
• Colorado potato beetle.

And even complete disinfection of the soil does not provide a 100% guarantee of the destruction of pathogenic microorganisms and pest larvae. Therefore, in the future, plants may be affected by these diseases.

Caring for joint crops

Cucumber care

Cucumbers are moisture-loving plants that require abundant and frequent irrigation with warm water. Settled water is ideal for irrigation. It is recommended to use a foliar spray. The optimal humidity in a greenhouse is 85%. If these rules are followed, the yield of cucumbers will be high.

For uniform plant growth and the appearance of ovaries, the temperature should be at least 22 and not exceed 28 degrees. Cucumbers do not tolerate ventilation and natural drafts. Do not forget about regular feeding of seedlings.

Until the cucumber fruits appear, water the seedlings frequently, but not abundantly. As a result, female flowers will form, which will allow you to harvest a good harvest. After the fruits appear, it is necessary to increase watering.

Tomato care

Tomatoes need to be grown in polycarbonate structures.

• The size of a proper bed should be 90 cm wide and 40 cm high. It is ideal to leave a passage between seedlings of approximately 60 cm. A passage between bushes must be required for comfortable growth and ripening of fruits.
• Seedlings whose height does not exceed 30 cm should be placed vertically in the ground.
• Add soil to the hole two weeks after the seedlings have taken root.
• For the first two weeks, you should refrain from excessive watering.
• After the stem is stretched, it must be tied to a trellis. The most optimal is considered to be an ovary of seven racemes with inflorescences. The resulting excess stepsons need to be trimmed.

Hydrogel - water substitute

Hydrogel is a salvation for many lovers of growing tomatoes and cucumbers together. This type of adsorbent ideally solves the problem of waterlogging of air and soil. Hydrogel crystals almost instantly absorb excess water during irrigation. And they pass it on to the roots of moisture-loving seedlings.

Since the hydrogel absorbs water, when watering, intense evaporation of moisture does not occur into the air, and, therefore, the humidity in the greenhouse does not increase. The adsorbent does not lead to a decrease in the level of immunity in tomatoes, but rather enriches cucumbers with liquid. Thus, it is convenient for two crops to grow side by side at the same time.

The hydrogel is ideal not only for absorbing water, but also mineral fertilizers dissolved in them. If you soak the granules in a fertilizer solution before the first use, you won’t have to worry about plant nutrition for a long time.

Mulch to retain moisture

If it turns out that cucumbers are already planted in a greenhouse without hydrogel, then it is recommended to use mulching. This method will help retain moisture at the roots of the plant and the evaporation process will be reduced.

Rules for using mulch:

• Prepare grass or weed clippings.
• After the cucumber seedlings appear, cover the soil around the seedlings with a layer of mulch (about 10 centimeters).
• Constantly add a layer of mulch as it settles.

Mulching will reduce the amount of watering. In addition, a layer of mulch generates heat, which cucumbers love so much. Moisture evaporation will occur under the mulch. The bottom layer of mulch, when gradually decomposed, releases heat and nutritious organic fertilizers, which are necessary for the growth of vegetables.

Soil for cucumbers

1. A distinctive feature of this plant is its increased requirement for carbon dioxide, which should be in the range of 0.3-0.5% in the air. Therefore, it is useful to fertilize cucumbers with solutions containing manure - when it decomposes, a lot of CO2 is released.
2. A balanced soil composition is important. For this reason, it is necessary to use complex fertilizers containing macro- and microelements.
3. The acidity of the soil for cucumbers should be close to neutral. Not higher than 7.0 and not lower than 6.5. Depending on these indicators, lime is used to reduce it or peat to increase it.
4. The microflora of the earth should not be toxic, but, on the contrary, “alive”. But at the same time, you should not allow fungal spores, insect larvae and pathogens to get into it. And to prevent those that already exist from becoming more active, massive decomposition processes must not be allowed in the soil. And for this point, it is better to take land for seedlings away from the roadway.
5. For a young plant, looseness and porosity of the soil is important for uniform distribution of moisture. Therefore, sand can be added to loamy soils, but clay should not be added for seedlings.
6. Especially for greenhouses, it would be good to add one of these components to the soil: leaf humus, peat, wood ash, moss, crushed eggshells, humus or grain husks.

What soil and growing conditions do tomatoes need?

Lighting

Tomatoes are a heat-loving and light-loving vegetable crop.

During the period of fruit ripening, the plant requires bright, intense lighting, otherwise the fruits will be less tasty.

• The seeds of this vegetable plant can germinate at a temperature of at least +14°C, but at higher temperatures (within 20-22°C) sprouts appear faster.
• And the growth of adult plants begins to slow down at temperatures below +12°C; shoots stop growing completely when the thermometer drops below +9°C.

Air humidity

The next requirement is optimal air and soil humidity.

Increased air or soil humidity can lead to the development of various fungal diseases, root rot, and blackleg. Some of these diseases cannot be cured, so the plants have to be destroyed.

Fertilizer

Tomatoes also require nutrients; plants can only obtain them from the soil. Therefore, the beds in which tomatoes will grow must be pre-fertilized.

• In the fall, when digging, organic matter (compost, humus, manure) is added to the soil at the rate of 10 kg per square.
• In the spring, when digging again, complex mineral fertilizers are added to the soil, and then beds are formed in which tomato seedlings will be planted.

And then the seedlings are fed with a solution of complex mineral fertilizers twice before they are transplanted into open ground.

After transplanting the seedlings into the beds during the flowering period and the formation of ovaries, the growing bushes require potassium and phosphorus.

These minerals contribute to:

• active flowering;
• the appearance of a large number of ovaries;
• strengthening immunity.

As a result, tomato bushes develop faster, a larger number of ovaries are formed, and the plants themselves practically do not get sick, which also has a positive effect on the yield of this vegetable crop.

Effect of nitrogen on tomatoes:

• This macronutrient has a beneficial effect on any cultivated plants.
• Activates the growth of vegetative mass and root system.

But it must be introduced into the soil with caution. An excess of nitrogen leads to increased development of green mass to the detriment of flowering and fruiting, and a deficiency leads to slower growth, lightening of the foliage, and the fruits will be too small.

Priming

The best types of soil for this vegetable crop are sandy and loamy with a neutral or slightly acidic reaction.

Under such conditions, the first fruits on tomato bushes can ripen 1-1.5 months after the flowers appear.

How to properly plant tomatoes and cucumbers in one greenhouse

In the case of joint planting, it is necessary to create average conditions for both crops, or apply zoning.

Temperature

Tomatoes do not tolerate high temperatures and stop developing if the air warms up to 25 degrees or higher. Cucumbers, on the contrary, are heat-loving. The minimum temperature for growing them is 22 degrees, but it is better if it is above 25. This means that 24 degrees is suitable for both crops. To prevent tomatoes from being too stuffy, they are planted closer to the entrance, where it is easy to reduce the temperature by ventilation. It is better to plant cucumbers at the end of the greenhouse to protect them from drafts.

Location

Experts recommend placing cucumber seedlings on the north side when planting together; here the plants will not be overdried by the sun's rays and water will evaporate less intensely after watering. And tomatoes need to be provided with ventilation to rid them of heat and excess moisture. If peppers are also planted in the greenhouse at the same time, they are assigned to the southern side of the greenhouse, and the tomatoes are placed in the central bed.

Landing

The ridges must be divided among themselves with sheets of roofing material or iron to prevent excess moisture from entering the tomatoes when watering the cucumbers and use a different fertilizer for each crop. The most effective way to delimit space inside a greenhouse is zoning. Typically, the room is divided crosswise, with its own compartment allocated for each crop. This method allows you to create your own microclimate in each part of the greenhouse.

You can make a permanent partition from cellular polycarbonate by cutting a passage through it, or making a door at the other end of the greenhouse. Some use a simplified version, constructing a partition from a thick film folded in half and thrown over a string or rod stretched at the top.

On a note! It is recommended to place a barrel of water in the compartment with cucumbers, which will warm up well and be used for watering; in addition, the evaporation of water can humidify the air.

When planting tomatoes and cucumbers together in one greenhouse, many summer residents use hydrogel, adding 0.5 cups of it to the holes when planting cucumber seedlings. Transparent granules absorb water and then gradually release it to the roots of a moisture-loving crop (in this case, cucumber), without creating excessive evaporation and protecting tomatoes from outbreaks of fungal infections.

Advice! Using hydrogel, soak it in a solution of mineral fertilizers before planting, so you can forget about feeding your cucumbers for a long time.

You can retain moisture near the roots of the cucumber using a thick layer of mulch. For mulching, mowed grass or weeds remaining after weeding are suitable. Immediately after planting the seedlings, lay the mulch in a layer 10 cm thick, and when it settles, add additional grass to the previous level. As the mulch decomposes, it will provide the cucumber roots with warmth and organic fertilizer.

Is it possible to leave the tomatoes in the same place?

It is not recommended to grow tomatoes in the same place for several years. It must be taken into account that the nutrition of each vegetable crop is carried out through its root system. Tomato seedlings have short roots that consume nutrients only from the top layer of soil.

If tomato seedlings are planted in a garden bed where tomatoes were also grown last year, they will suffer from a deficiency of macro- and microelements, which will negatively affect their growth, development and productivity.

It is best to choose vegetable crops for this area with a deep root system that “pulls” nutrients from the lower layers of the soil. These are eggplants, garlic, radishes or beets.

Gardeners also need to remember that tomatoes are distinguished by their ability to slightly acidify the soil, increasing its acidity level. For full growth and fruiting, this vegetable crop requires slightly acidic soil; accordingly, the tomato yield next year will be significantly lower.

But not every summer resident has the opportunity to change the area for growing tomatoes every year. Owners of small gardens and small greenhouses have to plant tomatoes in the same place every year. In this case, to maintain high yields of vegetable crops, it is necessary to properly prepare the site:

• remove the top layer of soil 5-6 cm thick, and if the tomatoes suffered from late blight - 10 cm;
• to disinfect, spill the soil with a solution of Bordeaux mixture or copper sulfate;
• fill the place of the removed soil with a mixture of leaf or turf soil, sand and humus in equal proportions;
• to reduce the acidity level of the soil during autumn digging, deoxidize it with chalk, dolomite flour or lime;
• In the fall, after harvesting tomatoes, plant winter garlic or green manure in their place.

The use of these agricultural practices helps restore the fertile qualities of the soil. But even when using them, experienced vegetable growers advise changing the area for growing tomatoes every 2-3 years.

Why is there compatibility between different vegetable crops?

When planting different types of crops, you need to take into account that some of them have a depressing effect on others. For example, tomatoes are suppressed by cucumbers, and beans are suppressed by onions. This action is associated with unilateral or mutual shading and differences in demands on growing conditions. However, there are combinations in which plants feel favorable.

What depends on it?

By following the rules of compatibility between different cultures, you can get many advantages:

1. Different crops feed on different microelements contained in the soil. This helps to avoid unilateral soil depletion.
2. Substances that are released from the roots of one plant affect the size and taste of the neighboring vegetable.
3. With proper placement of vegetable crops in the beds, you can harvest from spring until the first frost.
4. The various odors emitted by the leaves and fruits of certain plants help repel many pests. This keeps the vegetables healthy.
5. Compatibility during planting saves space in the garden.

Planting several plants in one place reduces soil fatigue and makes it possible to abandon crop rotation.
