The reasons for the fall of tomato seedlings

Growing crops at home always causes certain difficulties for gardeners. Quite often there are situations when a healthy-looking seedling begins to die. If you are able to timely determine the reason why tomato seedlings fall, then you can save the future crop.

The reasons for the fall of tomato seedlings

Watering

Tomatoes feel comfortable if they get enough moisture. If the drainage system is clogged, then the active rotting of the root system begins. If the drainage is inoperative, then the density in the soil increases and air through it does not enter the roots. First, the root begins to rot, and after it the whole stem is completely. Experts are convinced that this is one of the main reasons why tomato seedlings fall.

Tatyana Orlova (candidate of agricultural sciences):

The soil consists not only of soil particles, but also of the air space between them. Excess water displaces air, which leads to a deterioration in soil aeration. Plant roots also need air, like other organisms.

Seedlings tomato withers and falls if the tomato does not receive the right amount of water. Also, do not water the tomatoes very much, because an abundant amount of moisture leads to deformation of the roots.

Solution

If the drainage system fails, it must be cleaned. To do this, take a thin rod and slightly punch holes in the drainage. But, you need to carry out the procedure with special care so as not to damage the roots. After this, you need to loosen the earth and stop watering for several days so that the remaining moisture is absorbed.

With a lack of watering, you need to slightly increase its duration. With abundant watering, you need to stop it for several days. It is believed that the optimal watering interval is 1 time in 3 days. Remember that watering should be carried out with room temperature water so that the root system assimilates it better.

Temperature and lighting

Another reason that tomato seedlings wither and fall is due to improper temperature and lighting.

Tomatoes are heat-loving crops, but it is forbidden to place them near the battery, fireplaces or heaters, because they are very dry air, which leads to loss of moisture inside the plant. Also, do not place containers with seedlings in places of drafts.

Incorrect lighting is another indicator of seedlings falling. Tomatoes feel comfortable only in good light. With insufficient light, the stem of the plant is stretched. As a result, it acquires a thin stem and falls under the weight of the leaf mass. Unpleasant situations can occur if there is an overabundance of lighting. In this case, the foliage begins to curl and fall.

Solution

The comfortable temperature for tomatoes is about 23-25 ​​° C during the daytime and 16 ° -18 ° C at night.

Containers with seedlings should not be located in rooms where there are drafts. Choose the places where a maximum of 1 window is located.

When growing tomato plants, you need to place them in well-lit places. Tomatoes should be covered for 12-14 hours a day. If natural light is not enough for such a time, then you should start using special phytolamps. This time should not be exceeded, because at night the plants absorb nutrients better.

Wrong soil

Plants can die

If tomato seedlings fall, the reason may be in poor soil. Tomatoes do not like soil with a high acidity and alkalinity of the soil. Dense soil, which does not pass oxygen, also negatively affects plants.

Sometimes a plant fall occurs if you planted bushes too close together. As a result, bushes will lack nutrients, light, and oxygen. As a result, the plants die.

Tatyana Orlova (candidate of agricultural sciences):

If the pick was carried out in boxes or containers, then the planting pattern (distance between plants) should be 5 x 5 or 6 x 6 cm. A more thickened planting leads to elongation of seedlings. Too rare - uneconomical use of the nursery area.

Solution

When planting seedlings in a permanent place, give preference only to light and fertile soils. The optimal soil pH for tomato is neutral or close to neutral - 5.0 - 5.5. If you made a mistake the first time and tomato seedlings fall, you need to immediately transplant it to another place. Initially, the soil must undergo a disinfection procedure using a manganese solution.

Seedlings are planted in a certain pattern. Between the rows should keep a distance of 70 cm, and between the holes of 50 cm, so you need to dig up nearby bushes and transplant them at the correct distance.

Poor nutrition

The fall of seedlings may be due to insufficient fertilizers or their overabundance. If the tomatoes do not get the right amount of fertilizer, then all the foliage begins to turn yellow and gradually fall off.

With an excessive amount of fertilizing, burns appear on the areas of the roots or the main stem. Also, a large number of fertilizers leads to the formation of white plaque on the soil, which does not allow moisture and oxygen to pass through.

Solution

Tomatoes need only three top dressings for the entire growing season.

  1. The first top dressing is carried out 10 days after transplanting seedlings to a permanent place. At this point, you need to use a solution of ammonium nitrate. 20 g of the substance are diluted in 10 liters of warm water and poured 1 liter under each bush.
  2. The second top dressing is carried out at the time of flowering. This time you need to give preference to potassium substances. The preparation of the solution and the amount of fertilizer applied is carried out according to the instructions indicated on the package.
  3. The third top dressing is carried out at the time of formation of the fruit. This time you should use organic substances (humus or bird droppings). For each bush should be no more than 30 g of substance.

When a white coating appears, the top layer of the earth should be removed and irrigated with a humate solution for a week. In 10 l of water you need to dissolve 50 g of the substance. On 1 m2 should be about 5 liters of substance.

Viral diseases

Diseases negatively affect tomatoes

Quite often, seedlings fall if it is exposed to diseases. If disinfection of seeds or soil is not done on time, Fusarium or black leg may occur. Also, the cause of the impact of diseases can be poor-quality purchased planting material.

Methods of struggle

Give preference only to high-quality and disinfected seeds. If you bought untreated planting material, then disinfection can be carried out at home using a manganese solution.

If the reason lies in the soil, then try transplanting the plant to another place. You can also treat the earth with a copper-containing preparation Oksikh or a solution of manganese. Do not forget to remove from the garden all the tops that remained after the harvest, because bacteria can accumulate on it, leading to diseases.

It is impossible to get rid of the black leg. If it is available, you must immediately remove the diseased bush and burn it away from the garden plot, because bacteria can migrate to neighboring bushes.

Tatyana Orlova (candidate of agricultural sciences):

The black leg (rhizoctonia) is a disease mainly of seedlings, seedlings. Dive plants are less likely to be affected. It does not affect adult plants. But there are some fungal diseases that affect adult tomato bushes that have similar symptoms: southern late blight, streak (streak).

Prevention

So that seedlings are not exposed to diseases and their own fall, the following preventive measures should be taken:

  • water tomato bushes regularly, but within reason;
  • feed according to the clear instructions indicated on the package of the drug;
  • disinfect seeds and land before planting;
  • maintain optimal distance during planting so as not to thicken adjacent bushes;
  • so that water does not accumulate in one place and does not compact the soil, it is necessary to install a drainage system in containers or add sand to open ground;
  • loosening the soil will reduce the risk of most diseases;
  • airing, a normal level of illumination and the correct temperature regime allow preserving the health of seedlings.

Conclusion

If you manage to determine in time the reason why the tomato seedlings fall, then the treatment will be much faster and better. It is important to remember that it is impossible to delay the procedures for correcting the situation, because you can completely lose the future harvest.
