Friendly shoots on the windowsill bring not only joy, but also worries. Gardeners are looking for answers to the questions: why do tomato seedlings turn yellow, and how can they help their “pets”? You should approach solving the problem calmly, without haste. There is no urgent need to douse all plantings with potassium permanganate or antifungal drugs; perhaps there is no need for such a procedure. You shouldn’t ignore this sign and do nothing either. Figure out why this happened and accept it. necessary measures. Often there is no serious cause for concern and everything can be solved by creating a suitable microclimate and proper feeding. Cut off damaged leaves: they no longer benefit the plant, they only consume nutrients. Even if you think that there is no infection in the cut parts, for prevention, destroy them and disinfect your hands and tools.
If only the lower leaves turn yellow, most likely the process is caused by natural causes. The seedlings grow, develop, produce a powerful green crown, and set fruit. The lower leaves have already fulfilled their function, now they become only a burden. Individual organs also cling to life and die for a long time and reluctantly. Help your green friend, cut off the yellowed parts, and then all the energy of the seedling will go to the development of flowers and fruits.
Tomatoes love warmth, but this does not mean that they will survive in any high temperature. When it gets warm outside, utility workers usually heat batteries to the melting point of steel. Heating devices the houses are located under the windows, the sun's rays bake the seedlings through the glass, the radiator heats up from below - the poor plants do not know what to do, how to survive. No wonder the leaves turn yellow and curl. Try to find a place where tomatoes will grow at about 22⁰ during the day, and at night it is advisable to reduce the temperature to 17⁰.
If the leaves not only turn yellow, but also take on a bluish tint, check to see if the seedlings are experiencing sudden temperature changes. During the day, the seedlings stand in the scorching sun - the top part is hot, the dark surface of the pots is heated, the roots are warmed up in the warm soil. Evening is coming, it has become noticeably colder on the windowsill, especially if you leave the seedlings under the open window with the curtains drawn. Move containers with seedlings to places where heat and cold do not change so sharply.
Often the leaves turn yellow and curl due to inappropriate soil moisture. Tomatoes have a long root that draws water from deep layers of the earth. There is no point in moistening the soil surface several times a day. in small portions liquid, water infrequently but generously until water begins to flow out of the drainage hole. Tomatoes won’t like life in a swamp either; you don’t always need to moisten the soil, sometimes it’s enough to loosen it.
Often a change in color tells the gardener that the plant is not receiving the necessary nutritional components.
All these difficulties can be easily solved with proper fertilizing, necessary fertilizers and microelements. Sometimes there is enough of the necessary component in the soil, but it cannot be absorbed. To solve the problem, you need to water the tomatoes with special fertilizers or biological products.
You transplanted tomatoes from home to a greenhouse, and soon? This happens when the root system begins to develop too actively, all the nutrition goes to the underground part, and the leaves experience starvation. Typically, this phenomenon is caused by 3 common reasons.
In order for tomatoes to take root better in a new place, do not water them for the first week after picking and planting. Mulch the soil from drying out, cover from sun rays. If the weather is too hot and the seedlings are wilting, spray them with water. When you are going to plant tomatoes not in a greenhouse, but in open ground, 2 weeks before the “move”, start. Accustomed to comfortable warmth, it will not tolerate the cold at night and will begin to turn yellow and die.
Sometimes after picking, tomatoes begin to turn yellow. Common reason the fact is that the owners are too zealous in shortening the roots, and it takes a lot to restore them nutrients. After such an operation, the plant is weakened, the hot rays of the sun are harmful to it, and the boxes are moved to a dark place. The lack of light also prevents the tomatoes from recovering normally. Install lamps so that the seedlings are illuminated for at least 15 hours a day.
Leaves may also turn yellow in case of plant disease. Most often, tomatoes are affected by fungi that are transmitted through the air, water, soil and seeds. In the fall, everything and tools should be thoroughly disinfected. Buy soil and seed material well-known companies, but even in this case, before sowing, it is advisable to spill the soil with a solution of potassium permanganate, and keep the seeds in this solution. The fungus rarely lives in soil enriched with phosphorus and potassium; add such fertilizers to the ground before planting.
If the bush has acquired a heterogeneous pale yellow tint and, despite all care efforts, the seedlings wither and wither, most likely, an infection with the fusarium fungus has occurred. Take one of the most wilted seedlings and cut its stem crosswise. If you see brown rings, the diagnosis is confirmed. Special drugs, such as Fitosporin, are not effective enough against this disease; it is better to destroy the affected specimens.
The causative agent of fusarium wilt loves clay soil. If you have such soil on your site, add it a large number of sand
The change in color of tomato seedlings cannot be ignored. Plants cannot convey their request to the owner in words; they use other signals. If they curl or fall off, it means the tomato is asking for help or wants to tell the gardener about his mistakes. Not proper care, illness, uncomfortable conditions, excess or deficiency of some minerals or trace elements change the color of seedlings.
Damage to the root system after picking or planting immediately affects the condition of the above-ground part. If you, having listened to the advice of inept “agronomists,” greatly shorten the root when picking or bury the stem in the ground when transplanting, all the nutrients will go into underground organs, and the leaves will begin to turn yellow and die. If you don’t make mistakes and do everything right, you can save both yourself and your plants from unnecessary problems.
Tomatoes are an unpretentious crop, the seedlings of which are usually grown without much difficulty. But in the process of forcing seedlings from seeds, problems sometimes arise, one of which is leaf wilting. Why the leaves of tomato seedlings turn yellow and fall off and how to deal with this phenomenon, we’ll try to figure it out in this article.
One of the common reasons for yellowing leaves of tomato seedlings is a lack of any microelements due to insufficient soil fertilization. Most often, chlorosis develops due to a lack of nitrogen.
A deficiency of this substance can be unmistakably determined by the red veins with a bluish tint on the leaves, plus, the leaves throughout the plant are abnormally small. The lower leaves turn yellow and fall off.
Feeding will help ammonium nitrate. The fertilizer should be dissolved in water in a ratio of 40 g per 10 liters of water and 1 liter of solution should be poured under each bush. You need to try not to let the liquid get on the leaves to avoid burns.
Yellowing of leaf blades is also associated with potassium deficiency. Its lack poses a serious danger to seedlings than nitrogen starvation. In this case, ammonia nitrogen accumulates in the plants, and if measures are not taken in time, the leaves lose moisture, curl and die.
Wood ash should be added under each bush. To do this, take 5 liters of settled water, add 2 - 3 tbsp. spoons of ash, stir well and pour this mixture over the plants.
Yellowing of the upper surface of the leaves means phosphorus is needed. In this case, it is necessary to include superphosphate in the fertilizing (for 1 bucket of water - 3 tablespoons of fertilizer).
Another phenomenon that has a detrimental effect on seedlings is a lack of zinc. It is expressed in yellowing of the leaves near the petiole, spreading further along the leaf blade. At the same time, small yellow specks appear on young leaves. Tissue necrosis immediately affects the entire surface of the leaves.
Deficiencies of other elements are less common.
To understand exactly what to feed the plants, take a closer look at which parts of the seedlings have changed color:
To eliminate the deficiency of mineral substances, you should carry out foliar feeding of seedlings with ready-made complex fertilizers, choosing the most suitable composition and read the instructions.
Sometimes the reason for yellowing leaves is simple - lack of moisture. Tomatoes are quite unpretentious to soil moisture, but if the soil is very dry, the leaves dry out and the sprouts may die.
But you shouldn’t be too zealous with watering: a constant excess of moisture leads to “root suffocation” and even damping off of plants. First, the cotyledon leaves turn yellow and fall off, and then all the others. If the soil is waterlogged, you should stop watering until the soil on top dries out to ¾ of the depth of the pot.
The ideal regimen is infrequent, abundant hydration. It is necessary to water when the soil is completely dry.
Excessively dry air in an apartment can also cause yellowing and wilting of seedlings. If possible, the pots should be moved away from the radiators; another way is to purchase an air humidifier. Plants should be sprayed regularly with a spray bottle.
One of the main conditions for growing healthy and strong seedlings is a sufficient amount of light. The following factors are important:
It is believed that tomato seedlings need to be illuminated daily for 8 to 12 hours.
To determine how many lamps are needed for this, you should know that 1 m2 of seedlings requires 200 W. That is, if the area of the window sill is 1 m2 and it is all occupied by seedlings, and the power of the lamps you have is 100 W, then you will need 2 lamps for illumination.
Important! Lamps should be placed above the seedlings, the distance to the upper leaves should be at least 20 cm.
Tomato roots need enough space to grow. normal development. If the pots where tomatoes are grown are too small, the lower leaves of the seedlings begin to turn yellow. When picking for the first time, it is recommended to use containers with a volume of at least 200 ml, and the second time the plants are transplanted into pots of 0.5–1 liters.
If the temperature in the greenhouse rises above 30 ° C, the leaves of the seedlings begin to fall off. An anti-stress measure consists of spraying plants with a urea solution (0.5 tsp per 5 liters of water).
It does not work better on seedlings and hypothermia. Sheet plates acquire a bluish tint and fall off.
Ideal temperature regime for seedlings - 12 ° C at night, 22 - 25 ° C during the day.
Heavy soil, which does not allow air to reach the roots well, is not suitable for growing seedlings. You should not use untreated garden soil, which may contain pests and pathogenic bacteria.
Before use, the soil should be disinfected in one of the following ways:
If old containers are used, they should be washed with a solution of bleach diluted in water in a ratio of 1:10.
It happens that seedlings feel great, but after transplanting into a greenhouse, their lower leaves turn yellow. This is usually due to one of three reasons:
To make the seedlings easier to adapt, after transplanting they should be mulched and not watered for a week. If the greenhouse is very hot and the seedlings begin to wither, they should be sprayed with water.
Fusarium is a fungal disease that often affects tomatoes if not treated preventive measures. It manifests itself in the following:
Prevention consists of selecting varieties resistant to the disease and treating seeds and soil. The development of fusarium can be promoted by excessive soil and air moisture, so the greenhouse should be regularly ventilated.
So that tomatoes grow healthy and make you happy a bountiful harvest, you should not only take these recommendations into account, but also study the rules for growing the varieties you have chosen. Maintaining temperature conditions and proper care of seedlings will help avoid yellowing and wilting of leaves.
The general scheme for feeding tomato seedlings looks like this:
If you follow the rules for applying fertilizers, seedlings grow healthy and hardy.
Why do tomato seedlings grow poorly? This question worries many summer residents who sow tomato seeds for seedlings at home. Often, on the windowsill, the leaves of the crop become light green, its leaves curl and turn yellow. What to do if tomatoes wither, fall and grow poorly? How to correct the situation and cure tomato seedlings is described in the article.
We invite you to find out why tomato seedlings turn yellow and grow poorly
The leaves of tomato seedlings turn pale or light green quite often. This worries novice gardeners, because they do not know what to do in this case. Moreover, leaf lightening can be observed even with additional illumination of young plants. How to correct the situation and how to treat tomatoes?
Only the summer resident himself can determine the exact reason why tomato seedlings are pale green in color. This can be done experimentally, by assessing the situation, analyzing what is happening and gradually eliminating one reason after another. To identify the exact problem, we suggest taking into account the following aspects, namely:
Tomato seedlings turn yellow and grow poorly - this is a serious problem, but the situation can be corrected. If yellowed tomatoes grow at the dacha in protected soil conditions, then the yellowing of the foliage may be due to short-term night frosts. If we're talking about about seedlings that are grown at home, you should pay attention to the following points:
In case of dense plantings, it is better to thin out the seedlings and remove weak plants that are stunted in growth. The lack of soil in the seedling container is eliminated by picking the plants into larger cups. It is better to cover tomato seedlings in areas with cold climates under film at night. This will protect the plants from night frosts. Application complex fertilizers will provide the plant with minerals.
The stem of the seedling often turns purple, and the plant itself grows poorly. What is the reason? Botanists attribute this to a lack of phosphorus. There may be a sufficient amount of this microelement in the ground, but due to the cold weather the roots do not absorb it well.
It has been noticed that at temperatures below +14 degrees Celsius, phosphorus is practically not absorbed by the root system. After warming, the situation will return to normal. If the seedlings grew in a warm place and there is a suspicion that the reason is that the plant acquired purple in phosphorus-poor soil, then tomatoes are treated with the following drugs:
Chlorosis is a common disease of tomato seedlings and many other plants. With this disease, photosynthesis in the leaf slows down, which leads to a decrease in chlorophyll production. In practice, the vegetable grower notices that the tomato leaves turn yellow, but the veins remain green. The main causes of chlorosis include:
In connection with these reasons, a distinction is made between infectious and non-infectious chlorosis, which develops as a result of violation of the rules for growing seedlings and caring for them. Only a specialist can determine the exact cause after conducting a comprehensive laboratory study.
The photo shows chlorosis of tomato leaves
The main symptoms of chlorosis include the following:
What can a summer resident do to save tomato seedlings? Here are some tips:
The following drugs are used to treat tomatoes: “Ferovit”, “Iron Chelate”, “Antichlorosis”. Tomatoes growing in are affected by the mosaic virus. The symptoms of the disease are very similar in appearance to chlorosis. The pathogen is carried by ticks and insect pests. The drug “Afidol” is effective for treating tomatoes. It is worth resorting to seedling treatment if all other methods of treating tomato chlorosis have been unsuccessful.
Why do tomato seedlings grow poorly, turn yellow and fall? Determining the cause is not always easy, but if you know the symptoms of mineral starvation of plants, you will be able to eliminate all the symptoms of lightening of tomato leaves. It is worth inspecting the plants for damage to chlorosis or mosaic virus. Usually the introduction of complex mineral fertilizers allows the summer resident to solve the problem. How did you treat the tomatoes when their leaves turned light green and curled?
Nowadays, tomatoes are one of the popular crops due to their valuable and nutritional properties. For normal development and growth of tomatoes, it is necessary to maintain a temperature range of 23-25C.
Soil humidity should be approximately 70..80%, while air humidity should not exceed 60%. It is very important to provide the tomatoes with air. If there is a lack of air in the soil, the normal nutrition process is disrupted.
why tomatoes turn yellow in a greenhouse - tomato diseases Probably everyone who is involved gardening work, I had to deal with the disease of my favorite plants. And what a shame, when so much work and effort has been spent, so many wise books have been read, to find yourself in front of a helpless tomato bush, the leaves of which are colored yellow Very often, in a greenhouse, where it would seem that absolute care and attention is provided, tomatoes also turn yellow. What causes chlorosis of tomato leaves in a greenhouse?
When the seedlings are overgrown, the roots do not have enough space in the boxes or pots and they begin to die. Such roots are woven into a ball.
When the plant is planted in a greenhouse, the dead roots are replaced by new, grown ones, and young green leaves appear, but the old leaves no longer receive any nutrients and they begin to turn yellow. There's nothing wrong with that. The main thing is that the transplant does not occur too late.
The soil temperature may also be unsuitable for the plant, leading to leaf chlorosis.
Another cause of yellowing is excess water. In greenhouses, water does not evaporate as quickly as in the open air, so you should not be too zealous with watering.
If the weather is too hot and dry, it is difficult for plants to acclimatize. This is another reason for yellowing leaves.
An overabundance of fertilizers also leads to yellowness. Perhaps you shouldn't go too hard on them. List of reasons for yellowing of leaves due to chlorosis
The root can also be damaged mechanically, due to human fault, then only the lower part of the plant turns yellow. But the yellowness will go away as soon as the root grows.
Lack of calcium, sulfur or iron also leads to chlorosis of the leaves.
When the soil is poor in copper (for example, peaty), the leaves also acquire an unhealthy yellow color.
When the leaves not only turn yellow, but also begin to dry out, this is a sign that the plants do not have enough manganese.
An excess of phosphorus also causes the leaves to change their color, but a lack of it great harm will not bring, yellowed areas are quickly restored.
Plants may also lack nitrogen, and then they have a yellow-green color. Test “Why do tomato leaves turn yellow.”
After planting, I found yellowed lower leaves of the tomato bush. - It's not scary. The bush may have suffered a little damage during replanting, but as soon as it takes root, everything will be fine.
Sometimes when weeding I find the larvae of the cockchafer - a white worm. – The fact is that this worm, damaging the rhizomes of the tomato, disrupts the supply of moisture and substances beneficial to the tomato to the bush.
The soil in my garden bed is mostly peaty. – Feed your tomatoes with fertilizers that contain copper.
The yellow leaves on the tomato bushes have become hard. – Feed the tomatoes with sulfur.
I water my tomatoes every day. – Tomatoes like to be watered rarely but generously.
I water the tomatoes with a stream of water from above. – The tomato bush does not like watering from above, try to pour water between the rows.
The tomato bed is located in an open area with direct sun. – If the temperature is summer days does not exceed 30 degrees - everything is fine; but if the mark on the thermometer goes off scale, the leaf simply burns. When planning the bed, try to provide light shade.
The tomato leaves turned yellow and the bush stopped growing. – Perhaps fusarium wilt has reached your tomatoes. This is a fungal disease. It is necessary to renew the seeds (since the fungus can be transmitted precisely through them), and change the bed. It is better to burn the affected tops.
From now on, before planting seedlings, the tomato bush (root) must be treated with Bordeaux mixture.
I water my tomatoes with fertilizer every day. – Try to temporarily stop feeding the bushes - perhaps they are oversaturated with minerals and vitamins. And there’s no need for you to absorb extra fertilizer.
Tomatoes grow in a greenhouse. – Most likely your pets need a little too much moisture. Provide ventilation. I hope my test was useful for you and your pet tomatoes will now be beautiful and juicy. And you will enjoy gardening and the taste of tomato dishes.
How to save tomatoes from yellowing leaves?
The moment of planting plants in the greenhouse is very important. You shouldn’t keep them at home for too long for the roots to outgrow; you need to adhere to certain deadlines in everything.
Or, if you just can’t say goodbye to your favorite tomatoes, keep the seedlings in large boxes to prevent the roots from intertwining and dying.
But these are, so to speak, preliminary warnings. And when the tomatoes are already planted and their roots turn yellow, only spraying can help.
The fertilizer solution should be made weak, approximately one percent (the plants are still young and a large concentration of fertilizers can simply burn them). Solutions of fertilizers such as nitrates, phosphates, chlorides and others like them help well.
First of all, you need to ensure that the plants do not lack moisture. Water them well in the morning and evening.
A tincture of mullein with ash also helps well: one liter of mullein per ten liters of water; you need to take a glass of ash per liter of water, leave for two days, then pour this mixture over the tomatoes.
Tomatoes really like green fertilizer. Any green grass is mowed. Then it fills with it plastic container, according to calculation 23 and is filled with water. The fertilizer should be infused for two weeks.
Then a liter of fertilizer is diluted in a bucket of water and the tomatoes are watered with this solution.
Extreme enthusiasts can pour the solution over yellowed tomatoes chicken droppings. One liter per ten liters of water.
You can find a sufficient amount of fertilizers in a store or market; they will be especially useful when plants lack potassium or nitrogen microelements; the main thing is to strictly follow the instructions.
Tomatoes can be “fed” with fertilizer prepared with your own hands. To do this, put dandelion grass, nettle with roots in a barrel, fill it with water, then cover it with a lid and infuse it in a sunny place for 10-14 days, stirring occasionally. Then take out the grass, add 1-2 liters of solution per bucket of water.

in 2 days the tops of all tomato bushes turned yellow, and on lower leaves yellow streaks appeared. What to do? I sprayed it today with a solution of “Fitosporin-M”. What else can be done?

There are no initial data to even try to guess. Weather, feeding, age of plants, growing conditions, varieties, what was/was done to the plants before... Even better - photographs... Then MAYBE you can guess what happened...

The weather was bad until the last week until June 19, it was cold, during the day 14-16 at night 8-11 degrees and it was constantly raining. Now, for several days, t25 and every day it rains. On June 23, I sprayed both tomatoes and cucumbers with the “ovary” preparation, and on June 24, I fed the tomatoes with “AGRICOLA” for tomatoes and on June 25, the tops of the heads turned pale, and yesterday they almost turned yellow.
Tomato expert
Does Agricola contain boron? It’s just that the ovary is, as far as I remember, a solid forest. If there is also a lot of it in agricole, there could be, for example, an excess of boron. Signs of an excess (overdose) of boron: “The leaves of the plant turn yellow and become deformed, and they can curl down and take on a dome-shaped shape. Older leaves are affected first. The upper leaves first have a normal appearance, then curl. Signs of damage to young leaves and the top of the plant in advanced cases of excess boron can be mistaken for a lack of boron" (I’m guessing here on the coffee grounds, so know that the probability of the assumption being correct is not as high as we would like)
I planted tomatoes and after two weeks the leaves on some bushes began to disappear and only sticks remained. I looked at the rest of the bushes - everything is fine there - there are no signs of damage (no caterpillars, no snails, so you could say that something had eaten the leaves).
The same goes for eggplants and cucumbers. I’m very worried! This is my first year of gardening! I really wanted to help my garden with something!

I have been growing tomato seedlings in greenhouse soil for several years. This year large bald spots have formed. The seeds did not germinate, and if they did, the seedlings did not grow. A previous soil analysis did not reveal any pathology.
I didn't check for salt. Your advice other than tests. How to help seedlings grow? What to do with the soil?
Hello, please advise how to protect a tomato from the cold at night, I planted it in the ground on May 20th. Frosts are transmitted, how to cover each root?

Probably put the arcs in a tunnel and lutrasil on top. And if one is not tall, then cut off the top of the 5-liter bottle.

Depending on how and what leaves turn yellow, if only immediately after transplanting into a greenhouse or greenhouse, then don’t worry, wait a week or a week and a half.

Hello, for some reason my tomato leaves began to turn yellow a week after planting in the greenhouse, how many years have we been planting this has not happened, also on cucumbers the edges of the leaves along the contour have become light green, please tell me. Thank you.

Hello, Victor. Were there any weather anomalies this year? Maybe the ground was a bit cold?
Hello, on the leaves yellow spots and underneath there is a light green coating. What to do?
Tomato expert
Hello, it would be nice to look at the photos, but just at a glance - it could be cladosporiosis if you have them in the greenhouse... Although with it the coating on the bottom is brown, but at the beginning it can be light.
But two weeks after planting, the newly formed leaves began to turn yellow. The weather outside is cool. It rains almost every day. At night we turn on the heating.
Tomato expert
If the ground is cold (measure - bury the thermometer 10-15 cm), then you just have to wait until it warms up. Must be 14 degrees or higher. Maybe cover the ground with transparent polyethylene to help it heat up faster.
Just not black - it's of little use.
Hello. I planted the tomatoes in the greenhouse, they started to grow normally, new leaves, flowers and fruits appeared, but now the leaves are starting to turn yellow, the flowers are turning yellow and falling off. The bushes are drying up. How to save?
Tomato expert 06.06.2013 at 19:22 · Reply
Well, if the bushes dry up, I don’t know how to save them. In general, it can’t happen that your pets are starving?.. Then give them a leaf of calcium nitrate!
Or potassium. Depends on the soil... If, on the contrary, you feel unwell, due to illness or bad weather, then you need to determine and think.
It’s better to insert photos on the forum, or through third-party services - insert a link to the photo.
I don't think they are starving. Maybe I added a lot of cow manure to the beds before planting? Can manure have this effect?

Uv. Vitaly, tomatoes “do not like” excess nitrogen; with severe overfeeding, flowers/ovaries may fall off and a characteristic torsion of the top and upper leaves is observed. Yellowing due to excess nitrogen is theoretically possible if you overfeed too much, but I can’t say for sure.
Thank you, I’ll try to spill it with water, maybe I’ll save something.

Hello, dear Tomato expert. thanks for good advice and tips. Most of the bushes were preserved and restored. After “washing” the roots with water, the fruits were cracked and burst.
Now everything is back to normal. All the best.
There is an opinion that without timely picking, growing a healthy and strong seedlings tomato is impossible. This is not entirely true. Some gardeners grow tomatoes quite successfully without picking.
To grow tomato seedlings without picking, the seeds must be sown immediately in individual cups or pots.
Tomato seedlings are planted in the greenhouse in late April - early May, so the greenhouse should be ready by this time. Preparing a greenhouse for planting tomato seedlings involves covering the greenhouse with film, installing vents and preparing the soil.
Many summer residents prefer to grow tomatoes not in open ground, but in a greenhouse. Tomato seedlings intended for growing in a greenhouse are planted in closed ground in late April - early May. Exist various schemes planting tomatoes.
The planting pattern mainly depends on the tomato variety and their height.
To receive in the future good harvest, tomato seedlings after planting in the greenhouse must be provided with proper care, which consists of creating favorable conditions for the growth and development of this crop: sufficient lighting, timely watering, ventilation, tying, pinching, pollination and fertilizing.
Some mistakes when planting tomatoes in open ground can ruin the seedlings. To prevent this, before planting seedlings in open ground, you need to clearly determine the timing and planting pattern, as well as further care of the tomatoes in the garden.
Good seedlings are the key to a good harvest, however improper care picking up tomatoes after planting them in open ground can negate all your efforts to grow seedlings. To prevent various diseases of tomatoes, falling flowers, decreased yield, deterioration in taste and size of fruits, tomatoes in the garden need to be properly cared for.
Anyone who has experienced growing tomatoes knows firsthand that they are susceptible to numerous diseases that can spoil the quality of the fruit and significantly reduce the yield. This problem is especially acute when growing tomatoes indoors.
Many factors contribute to the development of various tomato diseases in a greenhouse. Read about how to reduce the risk of infection of tomatoes when growing them in a greenhouse.
Pest control annually causes gardeners a lot of trouble. Pests can significantly spoil the quality of fruits and reduce the amount of harvest. To protect tomatoes from pests, you need to be able to identify them and know how to combat them.
This is exactly what we will talk about today.
You so carefully selected seeds for sowing, grew seedlings, planted them in the ground, protected young plants from frost and drought in the hope of getting a good harvest, and suddenly your tomatoes began to deteriorate before your eyes. If this continues, it seems that soon there will be nothing left of the plants: the tomato leaves dry out, become stained, and the disease mercilessly affects green tomatoes and the stem. Most likely, the cause of this is a fungus.
Unfortunately, tomatoes are susceptible to so many diseases that it is sometimes difficult for a gardener to identify the cause of plant damage. In addition to the fungal diseases that we talked about in the previous article, tomatoes can suffer from viral and mycoplasma diseases.
There are no effective methods to combat them, but it is possible to reduce the likelihood of their development. Knowing the signs of a disease, you can identify it and analyze the causes of its occurrence in order to avoid similar mistakes in the future when growing tomatoes.

Today I’ll tell you how to water tomatoes after planting seedlings. permanent place. Correct mode Watering can protect plants from diseases and death, promotes good survival and rapid adaptation to a new place. In order for planted tomatoes to feel good, you should follow simple rules for watering and temperature conditions.
When purchasing seedlings, ask where they were grown, in a greenhouse or cold frame. After all, it depends on the conditions in which the tomato seedlings grew. further care follow them. If you grew the seedlings yourself, it will be easier for you to figure out how to properly care for them.
Tomatoes grown indoors on a windowsill require additional hardening. It’s good if you take them outside during the day so that they get used to the wind and sun. If not, when planting the plants will become very sick, if not die.
Same with greenhouse seedlings: pampered leaves will suffer greatly from exposure to direct sunlight and fresh air.
Do not forget that watering the planted tomato seedlings depends on several factors:
Hardened seedlings do not require shading; they can be watered generously once a day. Average consumption water is as follows: 2.5-3 liters of water for each hole (one bucket of water for 4 holes). If plants were planted in a trench, calculate the consumption according to the number of plants in the trench.
Water better in the morning, before the sun sets. If the scorching sun manages to dry the soil before the evening, then you can water it after the heat has subsided, consumption is approximately 1.5-2 liters per plant. This way you will provide the seedlings with moisture while maintaining the lightness of the soil: the roots also need oxygen.
If the soil becomes too compacted, the tomatoes will begin to suffer from a lack of oxygen. Therefore, you should not fill them too much.
It is enough to provide light moisture to the soil; this will be enough for the plants to feed and take root. Daily watering is carried out for 7-10 days until the tomato seedlings take root and begin to grow. When you notice that the plants have begun to grow, you can loosen the soil.
Loosening in the hole is carried out very carefully so as not to damage the roots (to a depth of no more than 3 cm). This is the so-called “dry watering”. This way you will disrupt capillary formations, reducing evaporation from the surface of the earth, plus delivering oxygen to the roots of tomatoes. Alternate abundant watering with loosening and rest: after walking with a hoe, loosening the soil well, you can not water for 3-7, sometimes up to 10 days ( in cloudy weather).
When the tomatoes become tall and powerful, it is better to completely mulch the soil: cover it with a 5 cm layer of young grass. This way you will protect the soil from overheating, there will be no need to fight weeds, you will have to water less often: moisture will remain in the ground much longer. When planting in the ground unhardened seedlings, care should be taken to shade them. To do this, it is covered from the sun and wind with agrofibre or spandbond for a while until it is accepted. Watering will be needed in the morning and evening, about 1.5-2 liters for each plant, depending on the weather and soil composition. Remember simple rules control of quality irrigation:
Once the tomatoes have begun to grow, it is not necessary to water them by hand. It is quite acceptable to water the leaves by sprinkling with a hose using a water pistol, a spinner and other devices. If you have any questions about how to water tomatoes after planting in the ground, ask, I will definitely answer.
