We will understand why the lower leaves of the tomato turn yellow

Very often during the ripening period of tomatoesyellowing and drying of the lower leaves of the plants is observed. At first, it is completely unclear why this is happening. After all, tomatoes were provided with sufficient watering, and bird droppings were brought into the soil with optimal amounts.

To combat this, you need to try to understand why the lower leaves of the tomato turn yellow.

If the old lower leaves have turned yellow before others and the color of the leaf plate has changed completely, and not just the vein where we

find a description of this phenomenon? Of course, botany will tell you that the reason lies in the lack of nutrients, namely nitrogen.

Oh, fragrant tomatoes! Their lower leaves turn yellow, but with new ones this does not happen. Is it worth worrying? No, it’s not necessary to worry too much about this.

Perhaps grown too "fat" and good-qualitytomato seedlings. Lower leaves turn yellow because it is a little overgrown. When transplanting from pots to a greenhouse in this case, the root system of tomatoes is a dense tangle. Too often, just such a seedling needs more time to adapt to new conditions. Therefore, one should not be surprised that the bushes of tomatoes start turning yellow leaves, from the lower to the apex. This is due to the onset of the development of diseases and the death of overgrown roots.

And why do the lower leaves of a tomato turn yellow?This phenomenon can cause fusarium wilt. It says about a dangerous fungal disease, which often suffers from tomatoes. It can be identified by withered leaves that have lost turgor. Looking at them, one might think that the plants did not water for two weeks. This disease is caused by soil fungi, which are able to live in the ground for a long time. It is because of them that tomato yield is significantly reduced.

The spores of such fungi are spread by the wind. High temperature is also considered a favorable factor, since the disease affects a greater number of plants in hot weather.

А почему нижние листья?Do not only lower yellow tomatoes. In fact, every plant has a risk of being affected by this disease, regardless of age: both at the time when tomatoes are seedlings, and at the stage of cultivation in the greenhouse or in the greenhouse, and during cultivation in

open ground.

Plant is affected by root diseasethe system. Then the disease goes to the stem. Mycelium grows and disrupts the vascular system of the plant. The disease develops and the plant weakens. There are cases when water and nutrients simply do not enter the leaves. There is a serious growth delay, accompanied by yellowing of the leaves.

Теперь известно о том, почему нижние листья у Tomatoes turn yellow. And one more small nuance. When the seedlings are transplanted to a permanent place, the lower part of the leaves first turns yellow and dies. Then the disease spreads to the upper areas and the plant dies completely.

But if tomatoes have a minimum scale of damage, then by the end of the summer they will start to get some small fruits. They will reach the stage of maturity ahead of time.
