Causes of pale tomato seedlings

Causes

Before you try to get rid of the problem of pale leaves, you need to find out the causes of this phenomenon.People gardeners identify several factors that affect the color change of the green mass of the tomato:

  • drinking water gets excess moisture;
  • tomatoes don’t get enough heat;
  • tomatoes feel a lack of oxygen;
  • the crop grows in a poorly lit area;
  • tomato plantings are thickened;
  • the root system of the crop is damaged;
  • tomatoes feel a lack of nutrients.

To step back if any of the reasons are not found worth it. Measures must be taken to eliminate them.

Excess moisture

Tomatoes love moisture. But you can not allow waterlogging of the soil under seedlings, and therefore it is recommended to water once every 3 days. This can occur due to frequent watering or increased humidity in the room.

Excess moisture leads to the fact that the root system of the vegetable crop begins to rot.This is followed by the gradual death of the sprouts. The foliage turns pale and takes on a lifeless appearance. In order to prevent the death of the plant, it is necessary to adjust the frequency of watering seedlings. A signal for watering the tomatoes is slightly dried soil.

You can get rid of excess moisture by organizing periodic ventilation of the premises with seedlings. In this case, take care of the absence of drafts.

Temperature

For comfortable tomato growth, a temperature in the range from 22 to 27 ° C is required. The night readings of the thermometer should not be lower than 16 ° С. The difference between day and night temperatures can be no more than five degrees.

To create such conditions, it is recommended to build film shelters. They must be airtight and resistant to winds.

Tomatoes can easily transfer heat to 40 ° C in just two days. After this, the process of photosynthesis stops at the culture.

Vegetable growers recommend leaving the windows and doors of the greenhouse open during hot summer periods. If the vegetable beds are in the open, you should build a shading canopy.

To transfer strong heat to the plants without damage will help plentiful morning watering. Watering should root zone, try to prevent moisture from getting on the foliage of tomatoes.

Light

Lack of light can adversely affect plants

Lack of light in tomato beds negatively affects the crop. Thin stems and pale leaves are just the beginning of trouble. If you do not respond to these signals, then the yield will be small. The rules that should be adhered to when cultivating the crop:

  1. To protect tomato seedlings from such problems, make the most of natural light. When constructing a greenhouse, use fewer floors, periodically wipe the windows.
  2. For a tomato, daylight hours can last from 14 to 16 hours. If tomatoes have been in the light for more time, then the leaflets of the culture are covered with whitish spots.
  3. When growing seedlings in the winter, it is worth taking care of additional illumination of the sprouts. For this, UV lamps are suitable. They are set so that the tomatoes receive direct light.
  4. On open beds, tomato leaves become colorless due to burns. This phenomenon can be observed in the summer, when the air temperature is too high. In this case, you should take care of the artificial shading structure.
  5. If the seedlings are burned, then the damaged leaves are removed, and the rest of the plant is treated with Epin.This will help the healthy part of the tomatoes cope with the effects of excessive light.

Thickness of the beds

Each gardener chooses the width of the tomato beds and the distance between the seedlings. When planting seedlings in open ground, remember that too closely planted plants on tomato beds will constantly stretch upward. Sprouts will become tall and thin. The green foliage will turn white.

This is because, as the tomatoes develop, they cast a shadow on each other. The culture receives less light.

Each sprout is placed in a prepared hole. They are placed at a distance of 60 cm to 1 m.

Damage to the root system

Pale leaves on tomatoes indicate damage to the root system. This happens when the sprouts are transplanted to a permanent place on prepared beds. Thin upper roots break off, the plant receives less nutrients.

With proper care, the root system of the culture will quickly grow , the plant will grow stronger, young green leaves will replace pale foliage.

Lack of nitrogen

Pale tomato seedlings can also be from a lack of nitrogen. To solve the problem, a urea solution prepared at the rate of 40 grams of dry fertilizer per 10 liters of water is suitable. This top dressing is used instead of watering the basal zone.

Gardeners recommend between the waterings in the evening to spray the tomato beds with urea solution. Get carried away by the introduction of nitrogen-containing fertilizing. This leads to violent growth of the green part of the plant.
