Why tomato seedlings fall and what to do

Anonim

Sometimes seedlings, seemingly he althy and strong, begin to wither and die. This can be avoided if you know why tomato seedlings are dying and help in a timely manner.

Unsuitable soil

Often the main reason why seedlings disappear is heavy soil and its high acidity. Such seedlings must be transplanted into other soil, otherwise they will fall and die. The new soil into which the transplant will be carried out should be decontaminated. To this end, the soil is calcined in the oven, frozen or watered with a solution of potassium permanganate, which kills pests that are in the soil and can damage young plants.Such prevention does not affect seed germination.

An important reason why tomato seedlings wither and fall is considered to be unjustified thickening of planted plants. Due to the lack of nutrients in the soil, sunlight and air, the tomatoes die. The optimal distance when planting tomato seeds in containers is considered to be 5 cm between rows, and 2 cm between such plants in rows.

Why do tomato seedlings die after picking

If the seedlings fall due to the density of seedlings, then in this case a dive should be carried out. The vacated space of the soil is sprinkled with ash powder or calcined sand. After a dive, tomatoes can stand wilted for another 2 - 3 days.

Tomatoes can wither if the pick was done incorrectly. Some rules for this procedure should be observed:

  • elongated seedlings of tomatoes are transplanted only after the appearance of 2 - 3 true leaves on it;
  • to form a strong root system, pinch the main root by about 1/3 of the part;
  • dive plants should be removed from the soil very carefully, after watering the soil with warm water;
  • seedlings taken out of the soil are placed again in the ground, making a sufficient recess so that the roots in the ground do not bend.

Also, when transplanting tomatoes, it is necessary to ensure that the soil is of the appropriate composition.

Pay attention! Excess moisture can have a negative effect on tomato seedlings, as well as its lack.

After the dive, watering should be limited for the next 2 days. In addition, plants are transplanted into containers in which holes must be made.This will help the roots get oxygen and also allow excess moisture to drain out of the pot. Stagnation of water can cause the leaves to curl and turn yellow. In this case, you can feel the smell of mold. As a result of improper watering, after a few days you can see that the seedlings are gone.

Pay attention to the negative effects of excess moisture in pots. It is better to take the necessary measures at the beginning of this process. To make sure the container has drainage holes, you can tilt it to the side. If they are not there, they are made with a hot nail on fire.

If they are clogged, the holes are cleaned to free the container from excess moisture to prevent seedlings from falling.

Insufficient watering

Tomato seedlings also die due to insufficient irrigation regime. The lack of moisture in the soil is characterized by its friability and increased dryness.But immediately abundantly pour tomatoes with moisture is not worth it. In this case, it is better to start with watering at 30 - 40 grams per 1 plant. Otherwise, the tomatoes will turn yellow. In addition, the soil in the container should be loosened. This process is also called "dry irrigation".

Low light

The next reason why plants can fall is thought to be insufficient light. The lack of light at the initial stage can be judged by such an external sign - tomato seedlings have stretched out. They require natural or artificial lighting for 12 hours a day. On cloudy days, it is necessary to highlight with fitolamps so that the seedlings do not stretch.

An excess of light flux also has a negative effect on tomatoes. Leaves may turn yellow, dry and wilt. Then the whole plant dies. Additional lighting with phytolamps at night is not required. Since in the dark the plant can absorb the necessary substances and oxygen.

Violation of the temperature regime

Elongated tomatoes may die due to non-compliance with the temperature regime. If the room temperature rises above +36 degrees, then the plants overheat and dry out. Therefore, containers should not be left near heating appliances. Also, at low temperatures (less than +15 degrees), tomatoes stop growing. +18 - +20 degrees is considered optimal for the growth and development of tomatoes.

In order for the tomatoes to harden, they are put out for the night in a cooler room, in which the temperature is 3-4 degrees lower. In addition, seedlings do not tolerate drafts. For this heat-loving plant, cold air causes wilting. Therefore, when airing the room, the container with planted tomatoes is removed away from the cool air flow.

Windowsill Growing

Before you decide to grow tomato seedlings on your windowsill, you need to close up the cracks to avoid drafts. It is also not recommended to open the window to ventilate the room. This can lead to the death of plants.

Why do tomato seedlings fall in containers exposed to the north side of the house? There is not enough light for her, as well as a lot of cold air. In this case, the plant is strongly stretched and acquires an unhe althy color. But the south side is also not a good place for young tomatoes. There they suffer from an overabundance of solar heat and overheating.

Lack of fertilizer

Lack of nutrients in the soil also affects the fact that the leaves turn yellow. Excessive dosing of fertilizers applied to the soil under tomatoes can lead to root burns and plant death. Fertilizers can also spoil the topsoil.If a dense crust with a whitish tint appears on the soil, then it should be removed, and the soil in the container should be watered with an unsaturated humate solution for several days.

Cause of death in diseases

When a tomato seedling is infected with a disease, it is not easy to save it. Even if the soil was disinfected before planting tomato seeds, but the foliage turned yellow and falls off, and the roots become dark in color, it is possible that these are manifestations of fusarium. What to do so that tomato seedlings do not fall from this fungal disease? You can try to save it by transplanting it into another container with soil that has undergone disinfection. But still, when buying seeds, you should make sure that the variety is resistant to this pathogen

When seeded tomatoes are infected with the black leg virus, it will not be possible to save the seedlings.It is necessary to remove them in time so that infection of he althy plants does not occur. The disease begins with the darkening of the main stem near the soil, and then the whole plant wilts. As a preventive measure to combat this problem, the soil is disinfected with a solution of potassium permanganate before sowing the seeds.
