Why cucumbers do not grow?

Even the cultivation of cucumbers in the greenhouse is not a guarantee that the plants will give a good harvest and will not get sick. Much depends on the gardener and their compliance with the rules of care, timely watering, good feeding, enough light and other factors.

In a greenhouse or open field, cucumbers can grow poorly and produce little fruit. The reason may be improper conditions or poor-quality care, in any case, something must be done. The soil should not be overdried or poured, the plants are also sensitive to the water temperature. Numerous diseases and pests are often the reason why cucumber bushes do not develop in the desired way.

There are several signs by which you can determine the negative impact of the disease:

• twisted leaves that fall;
• color change in foliage;
• the appearance of spots.

Any gardener, even if he is a novice, will be able to determine the appearance of the disease. Affected plants begin to die quickly if you do not give them help. For processing in specialized stores sold a huge amount of funds from rot, powdery mildew and other diseases.

Irregularly shaped cucumbers can be the cause of poor, unbalanced soil, poor in nutrients. As a rule, soil depletion occurs when a gardener plants a crop at the same place for many years and does not fertilize, although nitrogen and potassium are required for cucumbers at different stages of development. The situation is resolved simply, it suffices to take care of the introduction of humus in the fall, when the earth is dug up so that it is perfectly balanced in the spring. You can make as an organic fertilizer old tops and rotted leaves, manure, chicken manure.

The shape of the fruit can be understood that it lacks water. Cucumbers are very fond of moisture, but do not tolerate its excess. Humidity in the greenhouse should not exceed 85%, and the air temperature should be no higher than 35 degrees. You can determine them by installed thermometers. When watering plants in the garden it is also necessary to regulate the amount of water. On hot days, watering is carried out under the bushes every evening; in any other case, once every three days is enough. It is very important to monitor the temperature of the water, because from the cold bushes of cucumbers begin to ache.

With a lack of moisture plant:

• withering;
• turns yellow;
• bottom leaves fall.

With an excess of moisture:

• the stem becomes a brown shade;
• the root system is brown and does not grow.

If the bushes are planted too close to each other and do not comply with the required 20 centimeters, then there will be few fruits, and they themselves will not be in too much of a hurry to grow. It is not recommended to plant a vegetable next to plants that are well pollinated by bees, because then the flowers will be ignored. Often occurs and the crossing of species, which is not the best way affects the quality of the crop.

Sudden drops have a negative effect on the appearance of cucumbers, they also stop growing, and have a narrow waist in the middle. This happens when the plant too early in the ground, and at night the air temperature is not enough, so the bush suffers from cold weather.

If you do not pick cucumbers every day or every other day, then the root system will find it difficult to properly distribute the nutrients, because there are too many fruits on the stem. In this case, young cucumbers will begin to acquire an uneven shape.

The shape of the fruit and the speed of development may be due to the characteristics of a particular variety. Late-ripening hybrids are almost always curled into a bagel, as are Chinese cucumbers.

Fertilizer can be not only small, but also a lot, then a lot of foliage and few ovaries are formed on the bush. Lack of nitrogen always leads to twisting of the fruit, this is the first sign that it is time to add additional fertilizer to the soil.

In fact, in order for cucumbers to produce a good harvest, they don’t need much from a gardener. If it is a closed room, then it is important to pay attention to the observance of temperature. In the open ground should monitor the regularity of irrigation and fertilizer. If the bushes do not grow or grow poorly, bloom, but do not bear fruit or are not even tied, these are signs of serious problems.

The sooner summer residents notice the appearance of the disease and conduct high-quality disinfection of plants, the easier it will be to cope with the problem. Mealy dew is always a white coating on the foliage, which is impossible not to notice. The leaves begin to dry, and the fruits cease to gain weight, therefore it is required to immediately spray cucumbers with a fungicide. The main reason why it appears is cloudy, too cold, so the bushes do not have enough light.

With sharp drops in degrees outside, cladosporia develops rapidly, which looks like brown points of different diameters on the leaves. In the advanced stage, it also affects vegetables, which become impossible to eat even in salty form. So that it does not appear, it is impossible to water the plants with low temperature water, it is also required to regularly air the greenhouse. Treated bushes Bordeaux liquid 1%.

Overmoistened soil causes white rot to occur, especially if the distance during planting is not maintained. Infected parts are removed from the bush, and the place is treated with crushed wood or lime. The solution of copper sulfate helps to get rid of anthracnose - a disease that is also called the medyas. Few people know that the blame for all infected seeds, and sometimes the fungus that is preserved in the upper layers of the soil. This is one of the reasons why it is recommended to plant the soil in the beds before planting.

If we talk about the simple yellowing of the leaves, the most common cause of the problem is the temperature drop. In this case, gardeners recommend covering cucumbers on particularly cold nights. For this fit spunbond or plastic film. Helps to eliminate the problem of infusion of ash or onion peel. For 10 liters of liquid take 50 g of onions, and 3 tablespoons of ash per liter of water.

The main prevention of cucumber diseases is temperature control, since it plays an important role at the stage of seed germination and the subsequent development of fruits. In closed rooms, special attention should be paid to moisture, it can become the cause of mold. Top dressing and watering play an equally important role; in the first case, the plants dry out due to insufficient moisture, and in the absence of trace elements in the soil the fruits are twisted, the foliage turns yellow, the root system cannot develop normally.

Before spring, the gardener must do hard work and not only engage in the preparation of the soil and its treatment, but also the seeds. Top dressing is introduced as a preventive measure before the planting material is planted on the beds, as well as after germinating the seed, the appearance of the first three leaves above the ground and during the emergence of the flower ovaries. When cucumbers ripen, the need for fertilizer is detected individually, but, as a rule, cucumber consumes a lot of nitrogen from the soil.

To get a high-quality crop and to face less problems, you need to follow a few preventative rules:

• do not plant the culture on the previously infected place;
• regulate the temperature and not plant the seedlings too early in open ground;
• remove leaves and tops from the garden, not to throw at it after cutting;
• do not thicken the crops;
• watering in time, but not to exceed the rate of humidity;
• use only warm water;
• time to apply drugs from pests and diseases on the cucumber bushes.

It is worth taking care of the greenhouse, which after cleaning is a carrier of many diseases. Necessarily carried out spraying drugs with a disinfecting effect, as well as insecticides, for example:

• "Bayleton";
• "Formiod";
• Actellic;
• "Fas".

Often, the seeds are not pickled, and are the cause of the spread of certain diseases in the earth, which are then transferred to young plants. As a result of the use of such planting material, the gardener receives a small crop, the general wilting of the bushes, the appearance of spots on the leaves. The high efficacy of preparations for the seeds of “Gamair” and “Alirin-B” has been proven in practice. Five pills of one of the remedies are diluted per liter of water.

If you decide to first deal with seedlings, and only then proceed to its landing in the ground, you need to remember that in any substrate there are pathogens. Therefore, before planting seeds, the soil is treated with Glyocladin. It is a fungus that grows with a cucumber sprout and in time displaces all pathogens. The tablet is placed in a moist soil. When growing seedlings, biopreparations play an important role; they are the basis for the prevention and treatment of many diseases, especially root rot.

The fight against diseases is required not only during planting seeds or growing seedlings in pots, but also during the growing season. Sharp change of conditions leads to a decrease in resistance to microorganisms. To prevent the occurrence of negative consequences, experienced gardeners recommend before planting seedlings to make its processing "Alirin-B" and "Gamar". Apply two tablets per ten liters of water. If you want to enhance the effectiveness of drugs, you can use "Ecogel".

"Alirin-B" is ideal for the prevention of root rot. It has a long antimicrobial effect, copes with such diseases:

• anthracnose;
• askohitoz;
• powdery mildew;
• other fungi.

Any drug works fine and is drip into the ground through an irrigation system. You can also spray them, since such tools are fully compatible with fertilizers or insecticides. With the correct use of the means of prevention, any gardener can grow a good crop of cucumbers on his plot.
