The reasons that seedling of tomatoes fades can be a little. Without thorough visual inspection of sapling from top to the roots it is difficult to define the reason. It is necessary to offer one sapling which only has begun to wither, pull out it from soil with roots and to examine attentively.
All reasons of withering of seedling can be allocated in two main categories: errors in leaving and diseases.
Wrong leaving
Seedling of tomatoes loves moisture, but from stagnation of water, especially if drainage holes small or have got littered, suffocation of roots is possible. In this case the plant reacts withering of leaves, and roots at sapling look sluggish too. It is necessary to expand and clean drainage holes and to temporarily limit watering.
Seedling of tomatoes loves heat, but if to put it near the battery, it can begin to wither from dry air in the room. In this case roots by sight quite healthy. In order that saplings have ceased to fade, it is enough to rearrange boxes with seedling on other place, far away from the battery.
Seedling of tomatoes loves fresh air, but saplings, especially very young, are afraid of drafts. If seedling costs on windowsill and from open window leaf on it cold air gets, leaves can begin to fade too. It is necessary to replace the place or to stop draft. The most elementary – insufficient watering. If backs at the sapling taken from soil for survey have dried up, and soil too just is not enough for dry, so seedling moisture, it is necessary to water it more often.
Diseases
It is more difficult to struggle with diseases of seedling of tomatoes, than with errors in leaving or conditions of keeping. Diseases can arise not only because of the wrong leaving, but also because of the soil, especially if before landing of seeds seedling soil was not disinfected by calcinating or solution of potassium permanganate. Because of the wrong leaving there is such disease as black leg. The reason – excess of moisture and stagnation of water in box or pot. It is easy to find black leg. At this disease the sapling stipitate darkens and fades, beginning from below. Roots look at first healthy. And leaves wither. Then roots and all sapling perish. For prevention of black leg if seedling has begun to fade, weak solution of potassium permanganate which should water the soil in box helps. Because of not disinfected soil seedling fusariosis can affect fungal disease. At it leaves lose turgor, take form as if they were not watered long ago. In this case the disease begins with roots – survey will reveal sick faded roots of sapling. If to notice disease right at the beginning, it is necessary to replace seedling in the disinfected box filled with the new, not infected soil.
