Many people prefer to grow tomatoes on their plots. After all, this vegetable not only has high taste, but is also very beneficial for the body as a whole. Experienced gardeners They grow tomatoes so easily that they do not understand what problems can arise with this vegetable. However, inexperienced summer residents sometimes have difficulties. They can occur even at the first stage of vegetable growth, and these problems lie in the fact that the tomato seedlings do not grow. In this article we will tell you why this happens, what measures can be taken, and whether the seedlings can be saved.

Tomatoes are quite fastidious plants and require constant care.

Tomatoes and their beneficial properties

Homeland of the tomato - South America. The interesting thing is that wild forms of this plant can still be found there. Tomato came to our country only in the 18th century.

It's hard to imagine more healthy vegetable than a tomato. It is rich in vitamins and microelements such as vitamin C and B, starch, folic acid, nicotinic acid, iron, iodine, magnesium, calcium and many others. But the most important of them is lycopene. Thanks to this substance, tomatoes have a red color, and for humans it is important because lycopene is an antioxidant, and it can also fight cancer cells.

It's interesting that tomatoes are used in... medicinal purposes. For example, if you have problems with constipation, it is recommended to drink tomato juice every time after meals. This treatment is continued for two weeks. People with atherosclerosis are also advised to eat tomatoes in any form and as much as possible. Medicinal properties Tomatoes expand when combined with fats. So if you like tomato salad, seasoned sunflower oil, then this is only to your advantage.

Tomato salad is an easy and tasty summer dish that is easy to prepare even for a novice cook.

Tomatoes are also used in cosmetology. If you make a mask from tomato juice and apply it to your face, then within 15 minutes your skin will become more elastic. And with regular use of a mask of tomatoes and cottage cheese, you can get rid of wrinkles.

How to grow tomatoes

If you live in the northern regions of the country, where the summer is short, then it is best for you to grow tomatoes through seedlings. And if you expect to see the harvest as early as possible, it is also recommended to use seedlings.

Naturally, you can purchase seedlings immediately before planting them in open ground, but if you grow seedlings yourself, you will be confident in the quality of the planting material. In addition, when buying ready-made seedlings, you cannot always be sure what kind of tomatoes you will end up with. And when growing it at home, you can avoid these problems.

Before you start planting seeds, they need to be sorted and disinfected. Choose the largest and healthiest seeds. Such seeds must be the same size and have Brown color. Next, begin the disinfection process. You can choose a well-known and proven method. To do this, tomato seeds are placed in a light solution of potassium permanganate for half an hour. You can also choose a different disinfection method. To do this, tomato seeds are placed in aloe juice, diluted 50% with water. Keep the seeds in this solution for a day. After this method, tomatoes grown from these seeds will be stronger and have strong immunity.

Proper planting of tomato seeds in the soil implies their careful preparation.

Now start planting the seeds in the ground. Tomato seedlings grow in about 50-60 days. From these data you should calculate the time of their landing.

In order to plant seedlings, you will need to take:

pots or boxes;
fertile soil;
seeds.

Purchase soil for planting seeds at the store. Pour it into pots or a pre-prepared box and water generously warm water, make a small depression in the ground (no more than a centimeter). If you use a box, keep a distance of three centimeters between plants. Also if you plant different types tomatoes, then do not plant them in the same container. Place two seeds in each hole and sprinkle with a small layer of soil. You should not water at this stage. And later use a spray bottle for watering. Use it until the seedlings get stronger.

After finishing planting the seeds, move the pots to the windowsill, closer to the light. Also illuminate the seedlings with a lamp from time to time. In the room where your tomatoes grow, the air temperature should be 24 degrees above zero, watch this. Ready seedlings are planted in open ground on the 50-60th day, where they continue to be cared for, watered and periodically fed.

Why don't seedlings grow?

Sometimes it happens that the tomato seedlings that you planted grow poorly or do not grow at all. Why does this happen and what to do in such a situation?

The first time after planting, seedlings need special care And regular watering

There are several reasons why seedlings grow poorly:

Bad seeds. Your planting material was obviously bad. The seeds could simply be expired. It is not recommended to plant seeds that are more than 5-6 years old. And you might not have sorted out the seeds and then not disinfected them.
Unsuitable soil. To plant seedlings, you took bad soil. If you are not sure about the quality of the land, then it would be best to purchase it from a specialized store. Also, poor soil can be a source of diseases and pests.
Lack of light and heat. Another problem is why tomato seedlings do not grow. Tomatoes are very heat-loving and sun-loving plants, so a lack of one of these factors can lead to poor plant growth. Make sure that the room temperature is about 24 degrees and periodically turn on the tomato lamp.
Excess or lack of moisture. Proper watering is the key to success. The soil of the seedlings should not be allowed to dry out, but you should not create swamps either, otherwise the seedlings will not grow well. This important condition, why this culture is not growing.
a lack of nutrients. The seedlings will not stop growing because of this, but they may slow down in growth. Therefore, it is recommended to periodically feed the plant with fertilizers.
Cat. No matter how funny it may sound, but due to the fault of this animal, the seedlings may die. To do this, the cat just has to urinate in the soil with the plant. If there is a cat in your house, then under no circumstances allow him to get near the seedlings.

Follow all the rules for planting tomatoes, and you will succeed.

Why are tomato seedlings purple?

Moisturizing - watering should be moderate but regular.

What color is it? - 2 years ago

The stem of tomatoes is different shades. Consider the case when the tomato seedlings are purple.

Caring for seedlings after picking

The main stages of obtaining seedlings

Based on what has been said, it is quite understandable to want to grow these vegetables yourself in order to have a guaranteed environmentally friendly product.

When growing seedlings of vegetables or flowers, many gardeners are faced with the fact that the seedlings grow weakly or, conversely, become excessively elongated; leaves turn pale or curl; young plants look unhealthy and weakened. Fertilizer feeding does not improve the condition of seedlings. To get strong and healthy plants You must follow all recommendations for growing seedlings.

And there is no need to feed at this age.

4. Too dry or too wet soil. Tomatoes like infrequent watering (in room conditions 2 times a week), loosening (air access to the roots appears) and hilling (additional roots grow).

It’s not bad that they stop growing, it’s worse when they stretch out. They will grow up again!

If you comply with all these conditions, then you will have excellent seedlings.

And the seedlings may be susceptible to diseases if a lot of water has been poured and not enough warm temperature. Then the roots must be washed in a weak solution of potassium permanganate and transplanted into fresh soil.

Temperature - excessive low temperatures inhibit the growth of seedlings, optimally 20-23 degrees.

Usually, seedlings may not grow well due to bad seeds, maybe even expired.

The color transition of the stem and the underside of the leaves from green to purple can occur in two cases:

Basic care for pickled plants consists of regular watering, observing the temperature regime and timely feeding (approximately once every 15 days). Important: during the day the temperature can reach +20 degrees, but at night it must be reduced to +10 degrees.

Diseases of tomato seedlings

Without a doubt, tomato seedlings can be purchased from sellers. But there is a danger that they will sell you the wrong variety that you would like to receive. And it cannot be ruled out that they will sell you weak or diseased specimens. Therefore, self-grown seedlings are optimal.

Reasons poor growth there may be several seedlings; all of them need to be excluded, and then your
At this stage, the plant strengthens the root,
5. Standard varieties (with limited growth) may seem to develop more slowly at first glance.
Can be fed with fertilizer for growth. I use florist for growth.

If the tomato seedlings are purple

Because the tomato needs freedom. Make sure they are not cramped. First, they are planted in rows, and then transplanted (dive, if I’m not mistaken) into a more convenient container so that they can grow in width. It is also worth paying attention to the air temperature and the presence of the sun so that the earth warms up and is warm. The soil must also be nutritious. Maybe the factor that you have low quality seeds with low germination.

And seedlings begin to develop poorly if they are infested with pests - wood lice, spider mites, earwigs. Then the seedlings urgently need to be treated with phytoverm

Soil nutrition - if the seedlings have withered and turned bluish - there is not enough phosphorus, if the stem turns yellow and thinner - it’s time to feed with nitrogen.
Another important factor is land. I always plant in a ready-made soil mixture, which is sold in the tomato store. Of course, taking land from the forest would be even better, but that’s only if there is such an opportunity.

Not observed temperature regime for young plants (too low).

It is useful to fertilize with infusion of chicken manure. Although you can also use a solution of nitrophoska.

Why don't tomato seedlings grow?

Good luck and a good harvest!

IngaMus

What is your weather like? Seedlings are very sensitive to the weather. If it gets cold, it doesn't grow. It will get warmer...

There are several reasons why tomato seedlings do not grow. The most common reason is poor quality seeds It is better to buy those that are in demand or on the advice of friends. Also, do not forget to water the seeds, they love moisture. Monitor the temperature and proper seating. You can ask advice from people more experienced in this regard.

I can list the reasons why this happens:

The reason may be insufficient nutrition.

The third reason is the availability of sufficient light. It also has a very strong influence.

Esther

Tomatoes lack such a nutritional element as phosphorus.

Jennyfer

Please note: before planting in the ground, seedlings need to be hardened off.

It will be more effective if tomato seeds are germinated within 2-3 days. To do this, they are placed on damp cloth and put in a warm place. Humidity must be maintained by periodic misting until germination.
will be healthy and strong. The most common gardener mistakes that hinder the growth of young plants are: Sowing seeds in acidic soil Most flowers and vegetables require slightly acidic or neutral soil for successful development. You can check the acidity of soil purchased in a store or brought from your own plot using an indicator - a strip of litmus paper. A handful of soil is poured into 0.5 cups of water, mixed, allowed to settle, and the indicator is lowered into the water. If the litmus paper strip turns red, the soil is acidic. It needs to be limed, but this should be done in advance, 2-3 weeks before sowing the seeds. In this case, not chalk or lime is used, but ground or crushed eggshell(2-3 handfuls per 1 kg of soil). The pH of the soil will approach the optimal value for the development of seedlings. Adding an excessive amount of humus to the substrate for seedlings This contributes to the disease of seedlings viral disease"blackleg". To avoid this danger, the soil, along with the humus introduced into it, must be sterilized (steamed or calcined in the oven) or treated with biological products (Baikal, Siyanie). Excessively frequent watering of seedlings Young plants tolerate drying out of the soil more easily than waterlogging. Watering should be done approximately once a week, when upper layer the soil becomes dry to the touch, and the leaves of the plants begin to wither. Light deficiency In March, when most gardeners sow seeds for seedlings, daylight hours are still short. Especially in February (some plants need long-term cultivation before planting in the ground). To
The reasons why tomatoes may grow slowly can be varied.
...look at the roots.

Add a growth stimulator!)

Perhaps there are not enough seedlings sunlight. I also once planted some of the seedlings on the windowsill, and some of the seedlings on the table. So, what was on the windowsill grew perfectly, but the seedlings that were on the table did not have enough sunlight. And nothing appeared beyond the cotyledon leaves.

First: bad seeds;

If the stems and leaves of the seedlings are stunted, thin stems, small pale leaves, then there is not enough nitrogen in the soil

And of course, when watering, you must not overdo it, but also not dry it out.

But do not rush to apply fertilizers, which may be excessive.

We list the main diseases of tomato seedlings:

Planting hatched seeds

The first reason may be low air temperatures, so in such cases there is a slow growth of tomatoes/tomatoes, for good growth The temperature is +24-28 degrees, by the way, this temperature is important even for pollination and ovary growth, but not lower than 19 degrees.

The root system is growing.
Wait a little. It stays in this state (two leaves) for a long time. Then real leaves will appear and growth will begin.
There may be several reasons, but one of the most common is heavy soil. When I started gardening, I thought it would be better if I took black soil. but it’s all crumpled up, the roots are weak and there’s no strength to draw out nutrition. I had to dilute it with sand later.
Second: it’s cold, tomatoes love warmth;
If the underside of the leaves turns red-violet, then there is not enough phosphorus
Temperature is also important, but I doubt that it’s so cold in your apartment that the tomatoes don’t grow; most likely, some of the previous reasons are at play.

After all, these two reasons for color changes are very closely related. The stems turn purple because at temperatures below 14 degrees the roots do not absorb the phosphorus contained in the soil. This is probably where starvation comes from. But if the temperature is normal, and the stems have changed color, then you can try spraying. Make a 0.5% solution of phosphorus fertilizers and spray them on the leaves of the seedlings.

Late blight. To prevent it, it is necessary to alternate the usual feeding of seedlings with feeding containing microelements (potassium, iodine, etc.).

Edward

Seeds ready for planting are placed in cups or pots on a layer of soil (you can purchase ready-made soil in the store) and sprinkled with a layer of about 1 centimeter. Peat pots are good for these purposes. Their advantage lies in their ability to decompose in the ground. Then all the containers with the planted seeds are placed again in a warm place.

grew well during these months, it needs lighting with fluorescent or phytolamps. In February, additional illumination continues from dawn to dusk in any weather and on all windows. In March, in the same mode, seedlings are illuminated on windows facing north; On other windows, the lighting is turned on on cloudy days; on sunny days they are not used. Premature feeding of seedlings with mineral fertilizers You can only feed healthy, already well-developed plants, approximately 7-10 days after picking. More early feeding can only bring harm.

ValentinaK

Another suggested reason may be a lack of nutrients - that is, fertilizers, fertilizers are especially important - when tomatoes grow, as well as ovaries, fruit formation.

it’s better than it will last for a long time, feed immunocetaphyte tablets, a good growth stimulant and against some diseases

Tell me why the tomato seedlings are not growing, two leaves have sprouted and in this state for the second week they are about 2 cm high

Ekaterina Makarova

Possibly:

Anna Natalia

You need to know that at a temperature of 14-15 degrees, tomatoes stop growing. Very often this factor is the cause, but there may be others. May depend on soil composition. Feeding is already required here.

Tatiana

Third: the seeds are planted deep and they take a long time to germinate; a lot of effort goes into germination.

Natali

A lack of potassium is indicated by yellowness along the edges of the leaves and their curling.

Svetlana

If the tomato seedlings do not grow, then perhaps they do not have enough light, heat or watering. It may also be thickened and lacking nutrients. It is necessary to plant the seedlings so that they have a lot of soil, water them well regularly and add light at night. You can also water the seedlings with superphosphate.

Tatiana Tsivilskaya

However, a slight starvation in terms of phosphorus will not harm the seedlings at this stage.

Lyudmila Venediktova

Tomatoes, or tomatoes, have long and firmly taken their place in our diet. This is due not only to excellent taste, but also to high level usefulness. After all, tomatoes contain a whole range of important elements and vitamins.
The third reason is perhaps not proper watering, it is advisable to always water with warm water, especially during initial growth, as a daily ritual.
And mine are sitting in the cotyledon leaf phase.
1. At the moment, the growth of the underground part - the roots - is underway, then the above-ground part will begin to develop.
The extensions are growing root system- the roots will grow and begin to grow!
Fourth: you need to water it once every three days, or even four, so that the soil is moist, but do not overwater them; tomatoes do not like a lot of water.

With a lack of iron, tomato seedlings stop growing, the leaves become yellow and discolored.

When assessing the condition of tomato seedlings, several factors need to be taken into account:

Tatyana B

And with the restoration of the corresponding thermal regime the seedlings you planted will regain their healthy appearance.

Valentine Capricorn

Mosaic. If a sign of the disease appears, it is necessary to treat the plants with a urea solution.

Zhanna S

Sprouts most often appear on the fifth or seventh day. It is necessary to observe the temperature regime: during the day from +10 to +15 degrees, and at night it is better to reduce it to +8.
In addition, they are good to eat if there is a stressful period in life: tomatoes contain tyramine, which turns into serotonin when it enters our body. That is why when we enjoy tomatoes, our mood improves.
There may be several reasons: the soil is not suitable, hot or cold weather, diseases on the roots of plants. In the first case, now we can’t do anything except add fertilizer to the soil in the fall. In the second case, in hot weather water more often Cover the tomatoes cold with acrylic. And in the third case, we won’t be able to help in any way. But personally, if the tomatoes suddenly don’t grow, I water them with a yeast mixture. I take 100 grams of pressed yeast, dilute it in 10 liters of water, let it sit for a day and water the tomatoes with this solution. The result is already in a week. I repeat the procedure after 2-3 weeks. It is also important to hill up the tomatoes as they grow and trim unnecessary branches so that energy is spent only on branches that contain fruits or flowers.
Everything is fine.

2. There is not enough lighting - it is cloudy and there is no artificial lighting.
Do you remember to water? If not, there is a more complicated reason, Probably, most likely there is not enough space for the roots, there is no place for them to grow.... I am not a professor, but I think so!!!

Ask an experienced gardener why tomato seedlings are not growing or not developing very actively, and he will be at a loss. Farmers who have extensive experience in growing tomatoes on their plots sometimes don’t even understand what problems can arise with this. However, if this is your first experience with tomatoes, a lot of things can go wrong at first. Therefore, you need to learn how to competently save the situation in order to grow tomatoes at home.

Many novice gardeners sooner or later face a similar problem. Why do tomato seedlings grow poorly? To correctly determine the source of the problem, you need to understand that this process itself is multi-layered and includes several stages at once.

To begin with, the seeds are sown in the ground. As tomato stems grow, it is necessary to regularly trim the plant, carefully care for it, and also be able to protect it from pests. If any stage is violated, significant troubles arise, such as the cessation of tomato growth. How to cope with these types of problems and how to identify their presence in the early stages? More on this below.

Video “Possible Causes”

From the video you will learn what can cause poorly growing seedlings.

Poor nutrition

To determine why seedlings are growing poorly, it is recommended to first pay attention to feeding the plant. Very often, farmers do not pay due attention to this, and yet it is necessary to feed the tomato substrate, and this needs to be done about four times with breaks. What fertilizer methods are used:

the first method is carried out 3 weeks after planting the seedlings in the ground. You can prepare the solution using liquid fertilizer, 1 tbsp. l. nitrophoska. All this is mixed with 10 liters of water. Pour the resulting mixture under the tomato root at the rate of half a liter per sprout;
the second method is intended for secondary application of fertilizers to the substrate. Wait until the second cluster of flowers begins to bloom on the seedlings. Various store-bought fertilizers are used. Choose a proven product that can be diluted in water. Water the tomatoes with the solution, adding about 1 liter of water under each bush;
The third phase of feeding will be needed when the third flower cluster begins to bloom on the tomatoes. A fairly popular product is the “Ideal” fertilizer. It must be mixed with 1 tbsp. l. nitrophoska and dilute with water. It is recommended to pour the resulting mixture over the tomatoes at the rate of 5 liters of solution per 1 square meter. m. beds;
fourth recharge. It must be carried out no earlier than two weeks after the third feeding of tomatoes. How to prepare this kind of remedy? You need to use 1 tbsp. l. superphosphate, which is mixed with 10 liters of water. The volume of liquid for each bush will be in in this case the largest - up to 10 liters per square meter beds.

Bird droppings are also considered useful for tomato seedlings. It is filled with water, infused for several days, and then the root zone of the tomatoes is regularly poured with the resulting mixture. No problems experienced gardeners arise already at this stage. The thing is that it is very important to adhere to the specified proportions. If you overdo it or, conversely, apply too little fertilizer, the results will not please you too much.

Improper watering

What is the complexity of the process of growing tomato seedlings on summer cottage, so it is in the volume and regularity of watering. Remember that you should not overdry the soil under tomatoes. Excessive watering is just as harmful. The best option– water the plant at least once a week. However, their frequency will depend on certain weather factors.

For example, you started growing tomato seedlings at home, and placed a box or other container with tomato sprouts on the window or out on the balcony. In this case, the regularity of watering will depend on both the brightness and duration of lighting of the tomatoes. Observe how many hours a day the seedlings are exposed to open sunlight. If this period is long, be sure to increase the volume and frequency of watering the tomatoes.

Interestingly, it is not recommended to water tomatoes immediately after planting them in the soil. It is necessary to wait until the sprouts emerge from the ground, and only on the fifth day after this the seedlings can finally be filled with water. Use pre-settled water room temperature. This way you will prevent the accumulation of chlorine in the soil. If such a procedure is performed regularly and competently, the results will not take long to arrive.

Errors when diving

What to do if tomato seedlings grow very poorly? It is quite possible that the reason lies in improper implementation or even neglect of plant picking measures. Meanwhile, this procedure is quite important for the full growth of tomato seedlings. It will be needed if you sowed the seeds in one container, and now sprouts have emerged from the soil and it is time to separate them from each other. Be extremely careful.
This process is very scrupulous; in the process of transplanting plants that are not yet fully mature, their root system can be significantly damaged, and better case you will need time for them to grow. If you, as a novice gardener, do not want to bother with such procedures yet, this can generally be avoided. In this case, it is recommended to sow the seeds in different containers.

Other mistakes in care

If your tomato seedlings are not growing well, perhaps you have made some other mistakes in caring for the plant. Among the most notable are also:

poor seed quality. This determines in advance the result of planting them in the ground. Experts believe that it is undesirable to sow seeds into the soil that are already more than 5-6 years old. Therefore, if they are expired, it is better not to risk it;
low nutritional value of the land. Of course, land from the garden or the private sector is the optimal and a budget option. But, on the other hand, you will not be sure of its quality. What if you also get pests along with the soil? Therefore, it is best to purchase the substrate in a specialized store;
lack of heat. Flower growers also often do not stop attention on this. Meanwhile, the temperature in the room where the tomato seedlings grow should not fall below 24 degrees. Tomatoes are very heat-loving. Even if it’s cold in the room, turn on the lamp above the box with seedlings for a while;
fluffy pet - cat. Oddly enough, but it is your pet that can negate your efforts. It is believed that cat urine can destroy tomato seedlings, so try to never let your cat near a container with tomato sprouts.

When growing tomatoes at home, pay attention to every little detail. Only in this case will you be able to get full-fledged tomato seedlings.

Diseases and pests

Most often, novice gardeners are faced with a problem called root rot. Why does this problem occur? It's all about excessive watering. Let's say you water your plants too often, and at the same time you put the seedlings in a dark and cool place. Hence the root rot. But not only this disease threatens your tomatoes in this situation.

Particularly dangerous for tomatoes is the black leg - fungal disease. Plus, this infectious disease, which instantly affects the plant. If your seedlings “live” in one container, try to transplant the tomatoes into another pot or box as soon as possible before the remaining seedlings become infected.

Overall, growing tomato seedlings will not take too much effort.

Video “Tomato seedlings: from germination to picking”

From the video you will learn how to deal with seedlings from germination to picking.

Tomato seedlings do not grow - take action

When growing such a wonderful crop as tomatoes, gardeners face a number of difficulties; the most common problem is that tomato seedlings do not grow.

Tomato seedlings require compliance with certain conditions, for example, compliance with a special temperature regime. Immediately after the appearance of the first shoots, the boxes with seedlings are put into a cool place for a week; during the day the temperature should be 16-18 degrees C, at night - 13-15 degrees C.

Then the temperature can be increased to 20 degrees C during the day and 16 degrees C at night. The specified temperature regime is observed until the third true leaf appears on the tomato (approximately 30-35 days). During this time, the seedlings are watered 3 times at the root, the third time watering is carried out on the day of the picking, an hour before it starts. The recommended water temperature for irrigation should be 20 degrees C.

After the appearance of two true leaves, the seedlings must be sprayed daily (in the morning) with low-fat milk (1 glass per liter of water), this procedure is a prevention of viral diseases.

On the 12th day after picking, the seedlings are fed with nitrophoska (1 tablespoon per 10 liters of water). Watering is carried out sparingly as the soil dries.

If, under the specified conditions, the tomato seedlings do not grow or grow slowly, then the tomatoes can be fed with a growth stimulant, for example, sodium humate. The solution is diluted to a consistency reminiscent of tea in color and the tomatoes are fed 1 cup per plant.

Two weeks before planting, tomatoes must begin to be hardened by placing them on a balcony or under an open window. First for 2-3 hours then for the whole day. The hardening temperature should not fall below 8-10 degrees C.

Petunia seedlings grow poorly:

To each according to his ability

Sometimes seedlings do not grow for a simpler reason. Then, when the roots have completely used up the volume of earthen mixture offered to them, they have filled the seedling container and have nowhere to grow further. In this case, picking is needed, that is, transplanting the sprouts into larger cups or pots. The roots, and with them the above-ground parts of the seedlings, will immediately resume their growth.

Proper nutrition - “developmental” fertilizers

At two weeks of age, petunia seedlings already need feeding. If your seedlings are already mature and have been growing for a long time in the same soil, in which there are no more nutrients left, it is not surprising if the sprouts begin to “slow down”. Petunia does not grow well without regular feeding

Buy liquid or dry fertilizer with a high nitrogen (N) content - this is what is needed most at seedling stage for the formation of the above-ground part of the plant. Don't forget about the roots! To develop them, fertilizer manufacturers add phosphorus (P) to their products. Potassium (K) is responsible for budding, flowering and fruiting, so this microelement can be present in small quantities in fertilizers for feeding seedlings.

Petunia seedlings are watered with fertilizer, the concentration of which is 2 times less than indicated on the label (the instructions indicate the ratio of fertilizer and water for adult plants)

It is very desirable that the fertilizer for your petunia seedlings, in addition to the NPK formula, also include other important microelements: iron, boron, magnesium, zinc, etc. But only in chelated form (sometimes in salt form - not very successful)! Chelates are 2-10 times better absorbed than microelements in inorganic salts. Therefore, when using fertilizers with chelates, you can be sure that the microelements have reached their destination. Microelements begin to act very quickly and you will see the result!

Petunia seedlings are not growing - let’s start stimulation

Let’s say you’ve already changed the soil, applied the right fertilizer, and generally fussed with the seedlings like a sack, but the petunia still doesn’t grow well. Then we will apply plan “B” and use the “secret weapon” to stimulate growth - B vitamins. More precisely: B1, B6 and B12.

Dissolve 1 ampoule of vitamin B1 and B12 in a glass warm water(250 ml). The stimulating composition is ready! If the sprouts are still very small, take the solution into a syringe or pipette and carefully apply 1-2 drops to the seedlings. For adult seedlings, you can use the method of spraying the solution from a spray bottle. Do this procedure once every 7-10 days, alternating vitamins B1 and B12, and watch for increased sprout growth.

Vitamins for petunia seedlings can be bought at the pharmacy.

You can make another, more “killer” solution. Dissolve 1 ampoule of vitamins B1, B6 and B12 in 1 liter of water. Spray the seedlings with this cocktail once every 10 days.

After spraying with B vitamins, even the most stunted sprouts immediately begin to grow. A huge number of new growth points are formed, root formation is stimulated, and resistance to diseases and pests increases. At the same time, the seedlings grow squat, powerful and bushy.

What to do if seedlings in peat pots do not grow?

Peat pots are hollow conical cups. These are dry molded and pressed peat products, they are transportable and have a long shelf life.

Compared to improvised means (plastic, paper or ceramic containers), peat pots are biologically clean house for plants. The pots do not contain pathogenic microflora and weed seeds, and the content of toxic chemical substances: heavy metals, pesticide residues and benzopyrenes - below the maximum permissible concentrations (MPC) established for soil intended for the cultivation of agricultural crops. Peat is light, clean and safe to use, does not contain weed seeds and pathogens of various diseases of vegetable and flower crops.

Wall thickness good pots 1-1.5 mm, which guarantees the unhindered development of the plant root system along with maintaining the strength of the pot and the ability to quickly decompose in the ground (within 32 days after planting), thereby relieving farmers of the hassle of collecting parts of undecomposed pots when harvesting fields.

100% seed germination;
balanced nutrition of young plants with organic and mineral elements;
growth, healthy development and rapid rooting of plants;
optimal moisture and air capacity of the container for plants;
protection of plants from bacterial diseases;
high survival rate of seedlings due to a fully formed root system;
protection of the root system from damage and drying out during transplantation or transportation;
accelerated plant development due to the absence of the risk of injury to the root system.

But is everything really so rosy?! Based own experience, and also based on the huge number of reviews read on the Internet, I can say that rarely does anyone manage to achieve the above excellent results. There are several reasons:

Pots passed off as peat pots are often made from ordinary pressed cardboard. Cardboard does not decompose as quickly as peat, and this leads to the fact that in the fall, when cultivating the soil, the gardener sees an undecomposed pot with a tangle of roots. The roots of many plants are too delicate and cannot penetrate the walls that are overly compacted by stamping.

Peat containers for seedlings dry out quickly. Therefore, it is difficult to control watering of plants. If you don’t add enough, the plant may dry out. If you overwater it, mold appears on the pot and growing substrate, which has a very adverse effect on the seedlings.

A decrease in soil temperature, which occurs due to the abundant evaporation of water from the walls of the pot, is also harmful to delicate roots. In general, there are pros, there are cons, and the truth is somewhere in the middle. To maintain the benefits and reduce the harm of unfavorable factors, you can do the following:

To make it easier for the delicate roots of the plant to pass through the walls of the cup, you can hole it in several places in advance (this can be done with a regular hole punch).
Wrap each cup in plastic (food grade film is fine).
After purchasing, new cups must be soaked in a solution of humate fertilizer with microelements. This will feed the plants and speed up the decomposition of the cup.

If you decide that your seedlings will be better off in other containers, and don’t know where to put the already purchased pots, then feel free to plant seedlings of plants with a strong root system in them. For example, pumpkin. Its strong roots can easily break through the walls of a glass and such seedlings can be planted directly in a glass. permanent place residence!

Tomatoes, although not the most demanding plant, sometimes cause some problems both for 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 the temperature regime. At different stages of seedling life, tomatoes require 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 they get too much abundant watering 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 may not have existed before planting in open ground. 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.
Blackleg 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.
