Tomatoes in the seedling stage are one of the most unpretentious plants. Their seeds usually have good germination, and sprouts develop well and transfer the pick. But sometimes it happens that when growing a tomato an inexperienced plant breeder faces various problems: the seedlings dry and the leaves fall, they have spots, etc. Let's understand the reasons for this "behavior" of plants and learn how to prevent such errors.
If the leaves turn yellow and dry at the seedling tomato
As a rule, the yellowness of the leaves is a consequence of excessive watering in combination with a lack of illumination. Growing tomato seedlings, it should be remembered that it should be watered sparingly, each time drying the soil. If you "pour" the shoots with a lot of water, it will certainly affect the condition of the leaves and roots of the plant. Usually the leaves turn yellow and gradually dry up. In particular, this situation can be exacerbated if seedlings lack light. Therefore, always keep it on the brightest windowsill, shading at noon time.
Solve the problem of drying yellowed leaves, you can, transplanting seedlings in a fresh, good soil. During the transplantation, carefully examine the roots of the plants: they must be healthy, white. If the roots have signs of decay, yellowing, or even blackened, this seedling can not be saved.
After the transplant, the leaves may vomit, in this case, necessarily pritenite seedlings from the sun, and for a couple of days, her condition is normalized. But do not put it in a poorly lit room, otherwise there will be a cardinally opposite problem - the tomato leaves will begin to turn pale and stretch.
If white spots appear on tomato seedlings and leaves dry
White spots on seedlings can appear for two reasons.
The first is a fungal disease called septoriosis, or white spotting. The spots on the leaves will be dirty white, with a dark fringing. Septoria is tolerated with soil, it is very difficult to cure, so this seedling will not be viable. To prevent this disease, it is better to warm up before planting seeds or, on the contrary, to soil the soil in order to destroy fungal spores.
Another option is why the leaves with spots on the seedlings of the tomato dry, even under normal watering, is a sunburn. White spots in this case will be transparent. Such a situation can arise if several days in a row there was cloudy weather, and then a bright sunny day came out. Standing on a light window sill is not shaded seedlings very easily can burn on the scorching sun's rays. It will be able to restore the strength of the drug "Epin", as well as mandatory shading using conventional newspapers.
If the tomato plants dry leaves after picking
It also happens that a well-developed seedling tomato begins to turn yellow and wilt after the procedure of raspikirovaniya. This can occur when the root is injured during transplantation, and
But even if your tomatoes were not attacked by fungi before sunburning and did not get sunburn, the likelihood of yellowing leaves still exists. It's all about the quality of the soil you bought for seedlings. If you do not mix the soil yourself, be careful: an unscrupulous manufacturer could well regret nitrogen or overdo it with peat . And then, due to an overabundance or lack of nutrients in the soil, the plants will develop incorrectly and get sick. So, with a deficiency of potassium, the seedlings usually turn yellow and dry the lower leaves (the so-called old ones, which appeared the very first).
