Tomatoes are very bad seedlings. Tomato seedlings have stopped growing: we find out the possible causes and correct the problem in a timely manner. Why are tomato seedlings purple?

Tomatoes, albeit not the best whimsical plant, but sometimes causes some problems like experienced gardeners, and, naturally, for beginners. Tomatoes require special individual care and care, because if some nuances are not taken into account, the seedlings may begin to grow much worse or stop growing altogether. In this article we will look at the “requirements” for maintaining tomato seedlings and try to figure out what to do to avoid similar problems in the future.

Conditions of detention

Like most plant species, tomatoes require strict adherence to certain conditions in order to grow and produce good harvest fruits The first of these is worth highlighting temperature regime. On different stages the life of tomato seedlings is required different temperatures. When the first leaves appear, it is best to remove the seedlings to a cool place with a temperature of about 16 degrees. At night the temperature should not drop below 13 degrees.

After this, the temperature can be raised to 20 degrees during the day and 16, respectively, at night.

Proper watering of seedlings is one of the key things that must be observed when caring for them. Tomatoes should be watered regularly, but rarely. Even though they love water, the main thing is not to overwater them, because if you water too much, the plant may stop growing due to the lack of sufficient air in the soil.

Causes of Poor Growth

The reason for the poor growth of tomatoes after picking can be, oddly enough, a poor-quality picking process. This is one of the main reasons why tomatoes stop growing.

Picking, although not difficult, is a very important moment in the life of seedlings and therefore you need to approach it carefully. The greatest attention should be paid to the root system of seedlings. big problems this could turn out to be:

Bent roots during tomato transplantation
Severe damage to the root system during picking
Poor compression of roots when planting in the ground, which creates air pockets next to them, which leads to stunted growth of tomatoes

It is worth remembering that poor growth can also be caused by external factors, which before landing in open ground might not have been. These include diseases and pests.

If tomato seedlings are exposed to disease, they will naturally re-grow. Among the most common diseases, it is worth highlighting the following:

Root rot. It occurs if you overwater tomato seedlings at low soil or air temperatures. If you have identified this disease in your seedlings, you should immediately find plants with healthy roots and transplant them into new, fresh soil, but before doing this, wash the roots with a solution of potassium permanganate.
Black leg is another common tomato disease. This infection develops very quickly, so it is worth responding to it as soon as possible. Its symptom is the darkening of the root collar of the plant.

Tomatoes also have “enemies” among pests. Woodlice, spider mites, earwigs - all of them can have a very negative impact on the growth of tomato seedlings after picking. Therefore it should be processed by special means from pests.

Tomatoes are a favorite vegetable. In most regions, you have to grow tomatoes through seedlings. And at this stage, difficulties often arise: the tomatoes were planted on time, the seedlings do not grow well.

What measures need to be taken to correct the situation, as well as understand your mistakes in order to prevent them in the future.

How to grow tomato seedlings correctly

Seed preparation. Producing healthy plants for an early harvest starts with seeds. Therefore, you first need to check the germination seed. To do this, make a salty solution and pour out the seeds. Sick, weak, empty seeds will float to the top, and full-fledged seeds will sink to the bottom; rinse them in running water.

Now you need to disinfect the seeds in a solution of potassium permanganate for 20-30 minutes. You can use aloe juice diluted in half with water for disinfection. The seeds are kept in this mixture for a day. These methods will help increase the immunity of future seedlings.

To obtain strong, stocky plants, you should harden the seeds, which are wrapped in cloth, filled with a centimeter of water and kept alternately in the refrigerator and in a warm place for two days.

If the soil is of poor quality, it is impossible to obtain healthy strong seedlings. The soil can be purchased at a store from well-known manufacturers or prepared independently from humus, peat, sand, a little ash and complex fertilizer or superphosphate.

Tomato seedlings grow in 50-60 days, which allows you to calculate the sowing time. Pour the prepared soil into a box, water it, make furrows in increments of 2-3 cm, sow the seeds, cover with soil, cover with film and place in a warm place for germination.

Seedling care

Tomatoes are a heat-loving crop. Therefore, when growing seedlings, it is necessary to observe the temperature regime: daytime temperature should be 16-18 degrees, and at night 13-15.

When the seedlings have 2-3 true leaves, they should be picked into separate cups or pots.

Further care of plants comes down to timely watering and fertilizing. Pickled seedlings can be sprayed daily with a mixture of low-fat milk (a glass of milk per liter of water), which will protect the plants from viral diseases. Two weeks after picking, the tomatoes are fed with nitrophoska (a tablespoon of fertilizer per bucket of water).

And two weeks before planting tomatoes in a greenhouse or open ground, the seedlings should be hardened.

Why do seedlings grow poorly?

What can cause the slow growth of seedlings after they are picked into cups?

Nutrient deficiency. During this period, plants need nitrogen to grow green mass. With a small amount of nitrogen in the soil, plants develop poorly, have a thin stem, and small leaves of a yellowish tint. In this case, it is enough to feed the plants with a urea solution (a tablespoon per bucket) at the root. If a sheet with wrong side It has purple shade, then the plant lacks phosphorus, which is needed for the normal development of the root system. In this case, you need to prepare an extract from superphosphate or feed the plant complex fertilizer. Good result obtained by feeding with sodium humate - a growth stimulator. The solution is diluted to the color of tea and poured into a glass onto the bush. The first feeding after picking is carried out after two weeks and further feeding after 12-14 days.

Improper watering can also cause tomatoes to grow slowly. You should not allow the soil in the cup to dry out, but you should not over-water it either, as this can cause blackleg disease. Excess water reduces the resistance of tomatoes to temperature changes, and the plants become stretched. The seedlings are usually watered with settled water. room temperature once every five days.

Lack of lighting also slows down the development of tomatoes. In spring, the days are short, so it is necessary to further increase daylight hours by setting fluorescent lamp and turn it on daily for 12 hours.

Errors when picking: the root was severely pinched or bent, or maybe even broken, so the plant cannot develop normally. Read how to properly pick seedlings.

If there is a cat in the house, then measures should be taken to protect the seedlings from the pet. Cats are very curious and will definitely explore the plantings. And soil in pots can provoke them to be used as a toilet, which can cause the death of seedlings.

So we figured out how to grow tomatoes if the seedlings grow poorly, and found out the reasons for this. If you follow the rules of agricultural technology, everything will be fine, and the tomatoes will delight you with an excellent harvest.

Tomatoes are a favorite vegetable. In most regions, you have to grow tomatoes through seedlings. And at this stage difficulties often arise: dropped off on time tomatoes, seedlings grow poorly.

Depends on the quality of the seedlings future harvest, so poor seedling growth and leaf wilt is a serious problem that needs to be dealt with. There are many reasons for this phenomenon: the condition of the soil and even the care conditions created in the greenhouse. Tomato seedlings do not grow well in cramped conditions, in uncultivated soil and without fertilizers. Having considered all the common causes of seedlings withering, the gardener will save the future harvest.

Features of care

Seedlings grow quickly found immediately after planting or after the formation of the main stem of the bush. Culture develops poorly if it lacks free space. Lack of moisture and nutrients affects the condition of stems, leaves and fruits. Creating conditions for seedlings is the primary task of the gardener.

Why tomato seedlings do not grow or grow poorly:

the temperature regime is not observed;
insufficient nutrition;
lack of nutrients and vitamins.

It is important that before planting tomatoes in the greenhouse, the right conditions: first of all, before planting, the soil and all equipment are cleaned of harmful microorganisms.

Particular attention is paid to the temperature regime in the room, as soon as the first shoots appear, the culture boxes are removed to a cool place. During the day, the temperature should not drop to 10-14°C. The optimum temperature regime is 18 ° C during the day and 13 ° C at night, otherwise the seedlings will quickly dry out or begin to fade.

The bush develops well, which is sprayed with low-fat milk. This procedure will help avoid fungal diseases in seedlings. A plant planted in uncleaned soil or unfertilized soil (dry soil without added minerals and vitamins) does not germinate well. Whatever the reason for the poor growth of seedlings, it must be eliminated, otherwise it will not be possible to get a good harvest.

What does growth depend on?

The growth of seedlings is influenced by only 3 factors: the conditions created in the greenhouse or on open area, care and treatment of bushes. A problem at each stage of seedling growth indicates the reason why the plant is rapidly withering.

Tomato seedlings do not grow in depleted soil if the soil has been used for planting other crops for several years in a row, especially root crops. The nutrition of the stem and the development of lashes depend on watering, and in the future - the appearance of the first inflorescences and greens. Picking, which is carried out until the main bush is formed, is very important. Pests and diseases of tomatoes can affect the growth and formation of the first crop ovaries.

Soil quality

If seedlings grow poorly, the first thing to do is check the condition of the soil.

The soil determines the growth of the root system and main stem of tomatoes. If the quality characteristics of the soil are not suitable for the growth of seedlings, the leaves begin to wither, root rot appears. Another sign of poor soil is a bluish tint to the seedlings. The leaves turn blue if there is not enough magnesium in the soil.

Seedlings grow poorly due to lack of nitrogen.

The microelement is especially important for strengthening the plant and the growth of seedlings into a full-fledged bush. Nitrogen enriches the soil with oxygen and saturates the root system with it. Without nitrogen, a weak, deformed bush and small fruits are formed - it is impossible to harvest a good harvest in such conditions. The main symptom of nitrogen deficiency is the depletion of leaves and stems.

Solution

Magnesium helps the root system of tomatoes develop; if there is a lack of such an important element in the soil, the plant quickly weakens.

It is very difficult to obtain magnesium from natural products at home. It’s easier to buy magnesium-containing fertilizers that are suitable for feeding soil for tomatoes. Magnesium is sold in powder or granules. They are diluted with water: the resulting mixture is used to irrigate the soil around the bush and neighboring crops. To dilute the mixture to the desired concentration, use the instructions (you must adhere to the exact proportions).

What to do if there is not enough nitrogen in the soil:

fertilize with urea;
fertilize wood ash;
fertilize with purchased nitrogen-containing powders.

Nitrogen is sold in powder form, soluble in water. To dilute the fertilizer, use warm purified water (1 tablespoon of fertilizer per 10 liters of water).

If seedlings do not grow due to lack of nitrogen, fertilizer is applied 2 times a week for a month.

Use a nitrogen-containing additive for tomatoes with caution: excess nitrogen in the soil will harm the fruit. It is important to follow the instructions for the purchased fertilizer. If the top layers of soil are sprinkled with wood ash, the growth of seedlings is gradually restored.

Wrong watering

If there are no problems with the soil, but the tomato seedlings are still growing poorly, you need to reconsider the care. If the leaves of the plant begin to turn yellow, the tomato does not have enough moisture or there is too much of it. This leads to rotting of the root system of the future tomato bush.

Watering seedlings is scheduled according to the schedule: no more than 2 times a week during the period active growth tomatoes. Before planting the seedlings, the soil is watered and fertilized abundantly; the next watering occurs no earlier than a week later. The crop does not grow if excess moisture leads to rotting of the roots.

Solution

If you cannot determine the required amount of moisture for tomatoes, you need to check the quality of the soil. If the soil is dry, add water; if the moisture is not absorbed, stop watering for a while.

Installing an irrigation system will help solve the problem. Drip or autonomous watering will protect seedlings from excess or lack of moisture.

The moisture level varies depending on the location where the crop is planted: on the south side, moisture evaporates faster, and in the shade, irrigation water can stagnate at the root system. Temperature must be taken into account environment and the moisture level in the region where the crop is planted.

Wrong pick

Picking is the removal of the final part of the taproot. This procedure stimulates the branching of the root system and accelerates the growth of tomato bushes. If the picking was carried out incorrectly or the plant did not receive proper care after the procedure, the seedlings either do not grow at all or do so very slowly.

Reasons for insufficiently rapid growth of seedlings:

the root system is not bent correctly;
during the procedure, the roots were torn too much;
damage to the roots during planting in the ground;
the roots were poorly squeezed out, resulting in the formation of an air gap in the soil.

It is important to do diving according to all the rules: any damage to the root system of tomatoes can lead to the death of the crop. After picking, the plant does not germinate well, then it is necessary to check the condition of the root system and improve its nutrition.

During the entire subsequent period after the procedure, the soil is abundantly watered and fertilized. For feeding, natural fertilizers or mineral complexes are used, which accelerate the development of the main stem.

Tomato diseases

Diseases of the stem and root of tomatoes are the main problem of gardeners. Fungal diseases and infections affect the crop at any stage of development. Diseases are the main factor why seedlings do not grow or quickly lose juices. Common problems:

root rot;
blackleg;
late blight

Excessive watering of the crop or low ambient temperature leads to the appearance of root and basal rot. With this disease, the seedling does not grow for a long time and gradually rots.

The infectious disease (blackleg) develops quickly and spreads to neighboring crops. It is dangerous for the entire garden bed, so it is difficult to treat.

Solution

What to do if the seedlings become infected? If seedlings have suffered from root and basal rot, they should be urgently transplanted into new cleaned and disinfected soil. Plants severely affected by rot are thrown away. The soil after a diseased crop is replaced with soil washed with a solution of potassium permanganate.

It is possible to save a softened stem with a dark stem only at the initial stage of the disease.

Pests and insects

Tomato seedlings do not grow due to pests. Among them, the most dangerous are spider mite, woodlice or earwig. The leaves of a seedling attacked by pests turn yellow, their edges become deformed: holes or dark spots appear.

“Fitoverm” or “Aktellik” can help the culture. The products are used strictly according to the instructions.

Treatment land plot This happens on a large scale: diseased crops and neighboring plants are sprayed. An integrated approach will help get rid of pests and protect the future harvest.

Insecticides are used carefully, especially during the period of active growth of seedlings. The treatment should only be carried out by a professional.

Growing tomato seedlings is a rather complicated process. This problem is more common for beginners. Judging by the experience of those whose previous attempts were not successful, mistakes can be avoided as a result. Adviсe experienced gardeners to consider all aspects proper cultivation tomato seedlings. We will tell you in the article what to do if tomato seedlings do not grow well after picking.

There are several reasons why the growth of tomato seedlings stops. To correctly find and eliminate them, it is necessary to consider each of the possible options.

Before you take any action, you must determine the reason, after picking, seedlings do not grow because:

Watering was carried out incorrectly the soil is dry or there is excess moisture. If the reason is not watering, you need to check the drainage holes. It happens that novice gardeners forget about drainage; the lack of holes does not allow excess moisture to escape.
Plant development may slow down due to the fact that it is not suitable for tomatoes. priming. This often happens when seeds are planted in the ground from garden beds. The soil may be too acidic or too alkaline, so growth may be stunted.
The reason may be lack or excess of nutrition. Fertilizer application is very good sign growth stimulation, however, should not be done frequently. A large number of fertilizers will harm the plant.
Growth can be affected diseases or pests. Infected plants do not have enough vigor to develop to their full potential. After transplantation, the bushes experience stress; if diseases or pests are involved, development will stop.
If tomatoes slow down their development after picking, it means it was not done correctly. The roots are severely torn, damaged or bent. Also, during transplantation, if the roots are poorly compressed, air cavities may form - all these moments are harmful.

To ensure proper cultivation planting material, it’s worth checking point by point possible reasons.

Poor soil in which tomatoes grow

Novice gardeners do not always attach importance to the choice of soil, take soil from the beds. This is the main mistake; the growth of the plant depends on its quality. You can't save money on this.

It is preferable to buy ready-made soil or prepare the mixture according to existing rules. To disinfect it from germs, it is necessary to use special means. Otherwise, pathogenic microbes or pests will form.

If the soil is of poor quality, it needs to be enriched useful substances, add peat, fertilizers.

This problem can be solved quite simply; there is no need to disturb the seedlings. The soil is sprinkled on top, after watering everything useful will go to the roots. This point must be taken into account and the soil for planting must be prepared correctly. Tomatoes give good growth if the soil has enough nutrients.

Stress after transplanting tomatoes

For any plant, replanting is stressful; seedlings need to get used to new conditions. It takes time for the sprouts to take root, so it is so important to provide proper care.

Tomatoes need to be watched, watched temperature, watering, maintenance. Today, this problem is easier to deal with by buying a growth stimulator.
Special tools allow plants to survive a stressful situation.
Among experienced gardeners, a safe remedy made from natural substances is popular - sodium humate.
Thanks to stimulants, plants develop better because they have a positive effect.

Medicines that have a positive effect on the root system and increase the growth rate will help cope with stress. You should also increase the immunity of seedlings with Immunocytophyte or Novosila.

Use stimulants according to the instructions; the method of use is always indicated on the packaging.

Non-compliance with the rules of picking

First of all, the transplant must be carried out by timing. Reasons for incorrect picking:

Too overgrown or, conversely, a poorly formed plant will not take root well.
Before transplanting, the soil was poorly watered, which caused damage to the roots.
The seedlings for the picking period have one small root, if it is damaged, it will take a long time to recover.
If you transplant densely growing seeds, where the roots of the plants are heavily intertwined, problems can also arise.

Optimal age of tomato seedlings for picking 10-15 days from the moment of germination.

Improper care

As for home care, this is a very important topic, maintenance has a very strong effect on growth. This includes all the accents of watering, fertilizing, temperature conditions, and plenty of light.

be sure to water the plant after picking;
carry out watering under the root with settled water;
cold water when watering will cause harm;
weak sprouts do not like a lot of sun, better create shading;
the temperature should not be lower 20 degrees during the day, 16 degrees at night;
You cannot fertilize after picking; you must wait a certain period;
fertilize with nitrophoska no earlier than after 14 days;
any interference in the process of seedling growth is detrimental;
necessary check the soil for moisture, spray weak sprouts, slightly moistening the soil.

After picking, give the plant enough time for the first 3-5 days.

What to do to help seedlings grow better

Caring for tomatoes at the seedling growth stage is very important point, From him the quality of the harvest depends. The stronger the sprouts, the easier it will be for it to take root in the open ground. This work cannot be called easy, which is why many gardeners buy ready seedlings and only those who are patient manage to grow it themselves.

Below are tips to help your seedlings grow better:

Correctly organize the place where the trays with sprouts will be located. Best fit window sills or heated greenhouses.
Prepare the soil according to the recommendations; it should consist of: peat, earth, sand, rotted humus. Be sure to disinfect the soil with special means or heat it in the oven.
Check the quality of seeds and monitor shelf life. Harden them in the refrigerator, process disinfectants. The seeds may have fungi.
First days water only with a spray bottle. If the air is dry or hot, it is necessary to spray regularly to create a humid environment.
Before picking, as soon as 3 leaves have formed, water the soil well. This must be done in three stages the day before the transplant.
Replant in well-watered tray soil or peat pots.
Thoroughly press the ground so that the roots “settle down”. If this is not done, the roots may die.
In order not to form diseases (pests), for a long time gardeners used spraying with diluted milk at the rate of 1:4.

With the onset of stable warm days, at lunchtime, the trays are taken out to the street or balcony. This measure will allow the plant to get used to its natural environment to avoid stress.

To ensure good growth, it is necessary to pay attention to the soil, feed and water in time. If you follow the recommendations from the moment the soil is prepared to the pick, there should be no problems. By observing growth, any errors in care can be eliminated. Happy picking and rich harvests!
