Diseases of tomato seedlings and their treatment at home. Why is the tomato seedlings turn yellow, it fades and falls, grows poorly, thin and long, purple: what to do?

7 of the rules, having completed which, you can get excellent seedlings and a large harvest of tomatoes.

Why is tomato seedlings grow poorly or not growing?

Any plant cannot live without heat, sun, water and soil. Tomatoes are no exception, they need normal growth:

• High -quality seeds
• Fertile soil
• Enough light
• Moderate watering
• Optimum temperature of the earth and air
• Protection against diseases and pests
• Feeding with mineral fertilizers

If you fulfilled all the necessary conditions, then the plants will delight you with their powerful appearance and a rich harvest. If at least one of the points you made a mistake, they will upset you with frail shoots and meager, if any, a crop.

What to do if the tomato seedlings stretched a lot, has become thin and long?

After the seedlings appeared and pleased their owners, the most important stage in the development of plants begins. At this stage, the plants should get an acceptable temperature of the earth, air, a sufficient amount of light and moisture. What will happen if optimal conditions are violated?

If the earth in the pots for seedlings will if it is too cold and the air temperature is either too low or too high, the plants will not be able to fully develop.

Also, they will not be able to develop normally if they receive too little light. If the seedlings stretched out of the lack of light, you can save it by giving a sufficient amount of it.

Why is the tomato seedlings purple and grow badly?

Why in a relatively warm house, if you grow seedlings on the windowsills, the earth remains cold? Because often and densely, the cold that goes from the windows overly cools the pots with seedlings. For the experiment, put a room thermometer on the windowsill or on the soil of your greenhouse, if you grow seedlings under the film, and measure the temperature. The optimum soil temperature is from 16 to 18 degrees. If the earth is cold, the plants will grow poorly, and the color of seedlings can become purple.

Why do leaves turn yellow in seedlings of tomatoes: what to do?

Air temperature for seedlings should be from 25 to 28 degrees. Plants will lag behind in growth if the temperature is higher or below these indicators. Separately, I want to say about plant illumination.

If there is a catastrophically small light, seedlings can stretch out in just a few days. It will have a yellow color and thin elongated stems. You can expect a good harvest from such a seedling of a good crop if you can give plants a sufficient amount of light.

Why is the tomato seedlings withering and falling?

Unfortunately, on the windowsill without additional lighting, even if the windows overlook the sunny side, the plants will not be able to get enough light. The only way out in this situation is the use of artificial lighting. These can be special lamps that are used in industrial greenhouses and which are expensive or inexpensive fluorescent lamps.

The same failure can in wait for those gardeners who sowed the seeds in greenhouses with film shelter. Because in the early spring of sunlight, which can be lost when passing through a dense film is not enough.

Mold on the ground in the seedlings of tomatoes: What to do?

By watering seedlings, it is better not to add water than to give it in excessive quantities. It happens that gardeners are so carried away by caring for plants that they begin to water them every day or even several times a day. They are watered because they noticed the drying of the upper layer of the earth in pots, while inside there is an excess of moisture.

Black leg of tomato seedlings: struggle measures

Excessive watering leads to inhibition of plants, creates favorable ground for the development of fungal diseases of the root system and, ultimately, the death of seedlings. How to determine that plants need watering?

The easiest way in such a situation is not to water the plants before you noticed some wilting due to a lack of moisture. The leaves in this case are less elastic and slightly lowered down. Water plants with warm water. If you use chlorinated tap water, remove chlorine from the water.

To do this, it is enough to dial water in a bucket and let it stand for 2-3 days. Chlorine is gas and it is lighter than water, so it will completely come out of the liquid during this time.

Feed seedlings with mineral fertilizers. This must be done no more than once a week with complex fertilizers. Caution should be treated with top dressing like nitrate. Due to the high content of nitrogen in the soil, plants can stretch out greatly.

Processing of tomato seedlings from diseases

Do not allow infection of seedlings by pests and diseases. Since infection with diseases in a greenhouse or when growing seedlings on the windowsills occurs mainly due to infected land, use only healthy land for this purpose. If you take it in your garden, then take from the beds where tomatoes and cultures related to them did not grow, let's say potatoes.

Phytopher on seedlings of tomatoes: fighting her

Phytopharosis is considered an open soil disease and rainy and cool weather are favorable for its development. In order for the plants to get late blight, it is necessary to effect on them with adverse weather conditions within 3-7 days.

If the seedlings of tomato are under the shelter or in the house, the probability that it will get late) is very small. To prevent the disease, it is necessary to prevent water from entering plant leaves and water only the ground. If brown spots nevertheless appeared on the leaves, treat them with fungicides for late blight.

White spots on the leaves of tomato seedlings: what to do?

White spots on the leaves of seedlings can be the result of burns from the sun or lamps with which the plants are drilled. So, if not accustomed to the sunlight, move seedlings to the beds or put pots in the sun, the plants will not cope with the load that has arisen and receive burns.

Measures of prevention from burns can be a gradual addiction of plants to a new light regime. If the burns have already happened, the affected leaves can be cut off. The plant will gradually return to normal and give new leaves.

The leaves are twisted in the seedlings of tomatoes, wither and dry: what to do?

If the leaves are twisted in seedlings, it can be both the result of diseases and the result of the oppression of the plant with pests. What to do if the plants are sick and you cannot determine what is happening to them in their appearance?

The only way out in such a situation is to try to correct errors with the temperature regime, plant lighting, watering and treat them with fungicides from diseases and pest products.

Belkrylka - white midges on the seedlings of tomatoes: how to fight?

Maybe someone will be surprised that plants on the windowsill or under film shelter can have pests.

They, no matter how sad it is, if the earth was used infected with these pests. In particular, wealthy damage to the tomatoes can cause whiteflies and its larvae, which in a matter of days can turn a green plant into a stunted and weak. They will help to cope with the problem of spraying leaves with means from this pest.

Aphid on seedlings of tomatoes: how to fight?

Aphids may appear on seedlings of tomato if the soil infected with this pest was used. You can fight aphids by spraying plants with chemical products from aphids. Such as tanrek, confidor, spark of bio and others.

Unfortunately, it happens that all efforts to improve the plants are in vain. So it can happen if improper care of the plant, disease or inhibition of the plant by pests were too long. The only way out of this situation may be crossings of seedlings.

How to choose tomatoes?

Sow only proven, high -quality seeds. If you buy seeds in stores, use only trusted retail outlets. Because fakes in the seed market have reached a catastrophic scale due to the fact that selling high -quality seeds has become simply unprofitable.

If you collect seeds from your tomatoes, choose for this purpose only healthy and powerful bushes that gave a good harvest. Sometimes disinfection of seeds is required. Because they can be infected with pathogenic viruses. Disfection, if you conducted it correctly, does not affect the quality of the seeds, but can reduce germination. Therefore, you will have to increase the number of sown seeds.

In what soil are tomatoes grow better?

Sow the seeds in the land perfect for this culture. The soil for seedlings should not be too light and not too heavy. I must say right away that the land taken from the garden bed will be heavy if your garden is located on chernozems. And the soil purchased in stores called “for seedlings” will be too easy due to the large content of peat in such soil. Therefore, this option will be ideal: 50% of the Earth from the garden bed and 50% of the soil for seedlings are thoroughly mixed and fill the cups for seedlings or pallets with this soil.

In advance, it will be necessary to think about the fact that excess water after watering the plants will have to freely leave the glasses. This means that they should have enough holes at the bottom for draining excess water.

All these wisdom is easy to remember and use them, growing tomato seedlings. And most importantly - if you still have a failure in growing seedlings - not lowering your hands, but by pouring your sleeves and correcting your mistakes, growing a new beautiful, healthy and powerful seedlings.
