A gardener’s particular pain is sick tomato seedlings or other troubles that occur, due to which the bushes stop growing and developing.
Difficulties may arise at different stages of growth and development. This may be light, temperature, air humidity or unsuitable soil.
Let's try to figure out how not to get lost among all this diversity and take timely measures to save the future harvest.
Priming
It may be of poor quality or contaminated with pathogenic environment. Therefore, first of all, gardeners blame the soil in which tomatoes grow. Bad soil can prevent roots from absorbing nutrients. And if the soil is also dense, then the plants probably do not have enough oxygen.
To prepare the composition yourself, you need to mix peat, compost (biohumus) and 1/5 part sand, perlite or vermiculite.
Diseases
Root rot affects seedlings at any stage of growth. Therefore, beware of over-watering, dense sowing, temperature changes. Unripe compost and the same dense soil can also cause harm. For treatment, biopreparations based on hay bacillus, trichoderma or other soil microorganisms are used. Biospectrum, Baikal-M or their analogues are also used.
Picking
Not only the root shortening procedure, but also an innocent transplant can cause stress. It is advisable not to disturb the soil lump at the roots once again, and to refuse picking altogether - it is better to sow seeds in separate containers.
In addition, you need to know about the signals that plants give.
1. Leaves turn pale or dark – not enough nitrogen.
2. Leaves have turned purple or purple-purple – there is not enough phosphorus.
3. A pale yellow border has appeared along the edges – a sign of potassium deficiency. The shape of the leaves may also change or brown spots may form.
4. The top of the leaves is pale green – there is a lack of iron.
5. Flowers fall off, the tops curl downwards, and the veins on the leaves darken - there is not enough boron.
