If the plant does not like something in your care, then it signals it with the help of its leaves. They can change their color or curl up or down into the tube. Knowing what it means each of the symptoms, you can very quickly and easily help the plant to come to a normal state and grow further. If this is not done in time, then it can die or then give a bad harvest.
In this article we will consider the main reasons why the leaves of tomatoes are curled down by a tube and dry, and also find out what should be done.
Why do the leaves of a tomato twist down?
Gardeners are very sensitive to growing seedlings , so even a slight deviation from the norm in their condition causes them to worry. Not always their fears are confirmed. For example: if the leaves of a seedling have a tomato twisted downward and at the same time resemble a chicken foot in shape, then this is not a sign of the disease. This change occurs because the vein grows faster than the plate of the leaf, so it twists. Also, the twist of the ends of the leaf can be a species feature of the variety, which is more visible in young plants than in adults.
The causes of twisting down leaves in adult tomatoes:
- Feature of the variety. Such a structure of leaves is noted in tall varieties. These include Fatima, Okshart, Honey Drop and most varieties of cherry tomatoes .
- Infection with bacterial cancer. Identify this dangerous for plants disease can be on the following grounds:
- the lower leaves start to fade quickly, change color and wither;
- On the stalk and petioles cracks and sores are formed;
- when cutting the stem, a brown ring is seen across.
- phosphorus - the leaf plate becomes gray-green, and veins - violet-red;
- boron - young leaves twist, and the middle ones turn yellow with violet veins;
- sulfur - only young leaves are bent, on which then necrotic spots appear;
- copper - down not only the ends of the leaves fall, but also the petioles, later on they begin necrosis and chlorosis.
- Overabundance in the soil of boron and zinc. Too many of these elements are accompanied by the following symptoms:
- boron - the bent ends of the leaves become dry and brittle, the twisting begins from the bottom and reaches the top;
- zinc - old leaves are bent downwards, in which the underside of the leaf plate from the edges begins to acquire a violet color.
What if the tomato leaves spin down?
When a shortage of any food item, a tomato must be added to the soil. If you can not determine exactly what is missing, then you should take any complex fertilizer (for example: PoliMicro or Sudarushka), or spray the plants with an immunomodulator (Zircon, Epin or Solvent). With an excess of trace elements, it is worth pouring beds with tomatoes with clean water.
If you diagnosed that a tomato is infected with a bacterial cancer, then you need to get rid of it. At the same time, you should check the adjacent bushes. For prevention, all other tomatoes should be sprayed with a solution of copper oxychloride (40 g per 1 liter of water).
