Tomato seedlings grow poorly: we understand the reasons and correct the situation
Tomatoes are one of the most beloved vegetable crops, which many grow in their summer cottages. But far from always seedlings take root well in open ground. The reasons for this can be very different, and to eliminate each of them there are special tools and methods.
Not everyone knows how to use them correctly. Detailed instructions on how to protect tomatoes from diseases and speed up their growth will be presented in this article.
Why is this happening?
There are several reasons why a tomato does not grow well outdoors. One of them is improper feeding of seedlings. If due attention is not paid to this process, then a number of necessary substances will not be enough in the soil, as a result of which processes of a negative nature will occur.
- Small faded leaves and a generally frail appearance of the plant indicate a lack of nitrogen. Also, the stems of the plant become thin.
- Marble color greens acquires in case of lack of magnesium.
- Potassium deficiency is indicated by twisted seedling leaves. This problem is easily solved by adding potassium sulfate to the soil in the amount indicated in the instructions.
- When the underside of the leaf plates acquire a reddish tint, this means that they need phosphorus.
- The growth of tomatoes stops due to lack of iron.
Another reason for the deterioration of the condition of plants in the open field is the mistakes made in the process of diving. Dive is the removal of the central part of the root in order to allow the lateral root shoots to germinate.
Usually the procedure is carried out during the separation of seedlings from each other in order to avoid intertwining their roots in the process of further growth.
As a rule, the dive process must be carried out very carefully. But not all gardeners succeed. As a result, the root system may be damaged, and the growth of the seedling will stop. In this situation, it is necessary to wait until the damaged root processes regenerate. Also, problems arise if, after picking, immediately begin to fertilize the soil, as well as water the seedlings with cold water. If in the first five days after the procedure you do not monitor the condition of the soil, then the plants may die.
A very common reason for stopping the growth of seedlings are mistakes made during the care of plants.
- Wrong choice of seeds. It is important to pay attention to the fact that the maximum age of the seeds should not exceed 5 years. The younger the seeds, the more likely they are to germinate normally with proper care.
- Tomatoes are very sensitive to temperature. In the room where the seedlings are grown, it must be warm (at least +24 degrees Celsius). If the apartment is cold, use a heater or periodically turn on the lamp above the plants.
- The soil may not be sufficiently nutritious for good seedling growth. To saturate it with nutrients, it is recommended to buy special substrates.Also, you should not use soil taken from the garden - it is better to buy a special one that is designed specifically for growing tomatoes.
- Balance in soil moisture is important. Too abundant watering is undesirable, but also the earth should not be dry, so seedlings should be watered once every 7 days.
- Sometimes pets harm seedlings. If cat urine gets into the ground of seedlings, then further growth of the culture will most likely stop. Therefore, it is important to put the plants in a place that will be inaccessible to pets.
- Sometimes the condition of seedlings deteriorates due to stress, which they experience during the transplantation process. To facilitate this procedure, it is recommended to use sodium humate.
Diseases
In addition to the above problems, the growth process of tomatoes can be stopped due to a number of diseases that crop plants often suffer from. Consider the most common diseases of tomatoes.
- Blackleg is a fungal disease. Its symptoms are darkening of the lower part of the stems, drying of the plant and the process of decay in the root system. The danger of this disease is its contagiousness, therefore, if it appeared in one seedling, it is likely that the others will soon develop it. To prevent the mass development of the disease, diseased plants should be removed and moved to a separate container. Then you should take a new soil, mix it with calcined sand and wood-type ash. Then the new soil is sprayed with a special preparation called "Fundazol", according to the instructions. After that, the soil can not be moistened until it is completely dry.
- Another fungal disease is septoria. Its main symptom is the appearance of yellow-white spots on the leaves of tomatoes. These spots are framed by a dark border. The plant can become infected through the soil. Sick seedlings are finally removed, and healthy ones should be transplanted, thoroughly warming up and fertilizing the soil before sowing.
- A serious negative consequence of waterlogging the soil can be rot in the root system. It also appears when the seedlings have been in low temperature conditions for a long time. In this case, it is necessary to dig up the plants, thoroughly rinse the roots with potassium permanganate and plant the tomatoes in new soil. As an analogue of potassium permanganate, "Fitosporin" can be used.
- Growth retardation and wilting is due to a disease such as fusarium. Seedlings begin to turn yellow and wither from the lower leaves. This disease most often ends in the death of sprouts, but in some cases their transplantation helps.
If the growth process of seedlings stands still, it is not always worth referring specifically to diseases. An equally serious cause can also be parasitic insects.
Pests
Often, tomato diseases are explained by the influence of pests of various types. Common among parasites are spider mites, as well as earwigs and wood lice. To cope with them, you should use special tools, such as Actellik and Karbofos. In order not to cause even more harm to the seedlings, be sure to read the instructions on their packaging before using the preparations.
The main part of the pests attack the plants not when they are grown on the windowsill near the window, but when they are already transplanted into open ground. Young seedlings can be affected by some nasty parasites that cause plants to develop slowly or even die.
- whitefly. It can be seen by the accumulation of white midges around the plants. They form yellow spots on the green. To get rid of the parasite, you should use a garlic decoction, moistening the soil with cold water (such insects are afraid of temperature contrasts).
- The Colorado potato beetle feeds on tomato leaves. It should be dealt with using ash and soapy water.
- garden scoop poses a particular danger to plants recently planted in the ground. On the reverse side of their leaves, she lays a huge number of eggs, the larvae of which subsequently feed on greens. To prevent the appearance of a pest, weeds should be dealt with immediately after planting seedlings. And chemicals, such as Bitoxibacillin, will help get rid of the scoop.
How to accelerate growth?
If the seedlings froze in the process of development or show signs of discomfort, it is necessary to stimulate its growth and check the condition of the soil. There are various methods of helping plants: some gardeners prefer to use chemicals, others adhere to folk recipes.
Preparations
There are many ready-made preparations and growth stimulants that will help improve the condition of the soil and, as a result, the faster development of seedlings. The effect of the use of such funds is that the growth of plants improves, their immunity increases, they also become more resistant to the effects of various natural disasters.
Two weeks before transplanting into open ground, tomatoes can be watered with Athlete.It will help enhance the growth of the root system and slightly restrain the development of the part of the plant that is above the ground.
But in order for the aerial part to grow better, the seedlings are watered with a mixture of water and hydrogen peroxide. Peroxide is added in a proportion of 4 tablespoons per 2 liters of water. Moreover, this composition is not only watered plants, but also sprayed.
To replenish the supply of phosphorus, it is necessary to dilute 12 grams of superphosphate in a bucket of water.
To eliminate the gray color of plants and resume their growth, you should remove them in the shade and pour in a special solution: 25 grams of sodium sulfate is added to one bucket of water.
For tomato seedlings, there are several popular drugs that stimulate growth and improve the condition of plants.
- "Epin-extra" minimizes the content of nitrates, it also increases the resistance of plants to the effects of weather conditions. It is usually applied after the seeds have sprouted to strengthen the roots. The "Epin" ampoule is stirred in 5 liters of water and the plant is poured under the root with this composition. You can store the diluted drug only for a day in a dark place.
- A fairly powerful growth stimulant that promotes the formation of flower ovaries is "Zircon". And also it improves the immunity of seedlings. It is applied to the soil after seed germination, and tomatoes are also sprayed a couple of times a month. To have a beneficial effect on the roots with this tool, you can use it in combination with Etamon.
- A toxic but effective stimulant is Kornevin. It is used at the stage of seed soaking before planting. Dilute the product in the proportion of 1 gram per liter of water. For 6 hours, the seeds must be in this solution so that the seedlings are earlier and healthier.
- To increase productivity and resistance to temperature changes, a stimulant is introduced "Silk". In 2 liters of boiled water, the preparation should be diluted according to the instructions, and then the seeds should be soaked in it for two hours.
Folk remedies
Many experienced gardeners know how to make various mixtures at home to feed their plants, as well as what ingredients to use to improve their growth. You can help seedlings on your own in several proven ways.
- If there is little nitrogen in the soil, dilute 4 grams of urea in 10 liters of water and water the plants with this composition.
- Bird droppings can be used as a nutrient for the root system. It is usually filled with water and infused for several days. This mixture is poured under the root of the plants.
- Eggshell infusion is made from the shells of 3 or 4 eggs. It is crushed and placed in a plastic bottle and filled with water without closing the lid. After 5 days, when the water is infused and enriched with the necessary substances, seedlings are watered with it. For each plant, 1 teaspoon of this fertilizer is needed per day.
- Yeast can be used to make the soil looser and thereby help the plant absorb nutrients. For 2 liters of water you need 10 grams of yeast (fresh). After a day, when the mixture is infused, such fertilizers are added to the soil after watering it.
- You can enrich the soil with potassium using a banana peel. In a jar with a volume of 3 liters, put the peel from 4 bananas and fill it with warm water. After 3 days, you can use the infusion, introducing it into the soil after watering.
- To improve the growth of tomato seedlings in February and early spring, the lack of light must be filled with special fluorescent lamps.
Helpful Hints
In order for seedlings to develop without problems, it is important to heed the advice of experienced gardeners.
- As the most suitable place for placing seedlings, a heated greenhouse, as well as insulated window sills, is suitable. But do not place a container with seedlings near radiators and heaters.
- The soil, in addition to disinfecting components and nutrients, should include the following mandatory elements: earth, rotted humus, sand, peat.
- To avoid the appearance of fungal diseases in the future, the seeds must be hardened. To do this, they are kept in the refrigerator before planting. Also, such diseases will help prevent hydrogen peroxide.
- When warming comes, seedlings should be periodically taken out to the balcony. So you can gradually accustom the seedlings to their natural environment and reduce their stress when transplanting into open ground.
- A day before picking, it is recommended to moisten the soil. Moreover, watering must be done in three stages.
- As a preventive measure against the formation of diseases, sprays can be prepared, which include milk.
- If you notice that some of the plants become lethargic, do not put them under the open rays of the sun, dose the amount of light so that the seedlings recover.
- To prepare tomato seedlings for planting in open ground, it can be watered with rain or melt water.
- It is necessary to monitor the condition of the soil, especially the level of its acidity. For this, a special indicator is used. 1⁄2 cup of water is mixed with a handful of earth, then an indicator is lowered into the mixture, which measures the acidity.The red color of the strip, showing increased acidity, indicates that before planting the plants, it is necessary to carry out liming of the soil with the help of eggshells.
- When using chemical growth stimulants, be sure to wear gloves as some products can be toxic.
Thus, taking into account all the features of growth and the availability of the necessary conditions for tomatoes, it is possible to keep seedlings healthy throughout the entire germination period, minimize their stress when transplanting into open ground and prevent the occurrence of dangerous diseases and pests.
With all of the above recommendations, you can grow a truly rich crop of tomatoes. For information on what to do if tomato seedlings almost do not grow after planting in the ground, see the next video.
