In greenhouses, this crop grows remarkably, and if you follow all the necessary rules, you can harvest all year round. So, initially it is worth knowing that the composition of the soil, the method of planting, watering, fertilizer, as well as the fight against parasites are primarily important for any plant.

Rules for growing cucumbers indoors

The first step is to prepare the ground. A few weeks before planting, the soil is disinfected with copper sulfate, then a mixture of peat, humus and soil is prepared.

It will be good to initially fertilize it with superphosphates, saltpeter and potassium sulfate.

Many experts recommend this composition, although the soil with coniferous sawdust also proved to be excellent. Properly prepared soil is a pledge of a bountiful harvest.

Planting is carried out only by seedlings, it will give early fruits and will allow initially to control the adopted bushes. In the case of sowing seeds, it is rather difficult and time-consuming to grow a healthy culture in a greenhouse.

As soon as the bushes get stronger, they need to be provided with support initially, for this purpose, tapestries are installed, to which the twine is further attached to entwine and fix the plant stems on it. In the future it is necessary to follow the rules of watering and timely feeding.

Causes of cucumber disease

Soft cucumbers can be due to the impact of the following factors:

  • improper watering;
  • close landing;
  • lack of moisture;
  • wrong temperature condition;
  • defeat plants fungus;
  • planting in close proximity to tomatoes;
  • lack of top dressing;
  • insufficient lighting.

In order for cucumbers not to be small, soft and empty, they must be watered correctly inside them. Namely, it is necessary to strictly comply with the requirement - to water young and adult plants only with separated and warm water.

Watering with cold water can lead to illness and stop the growth of the bush. Most experts recommend watering in the evening. Perform watering is 2-3 times a week.

Attention! One of the main reasons for the softness of the fruit is cramped, it is closely planted plants do not allow the root system to develop normally, and there is a weak development of culture.

Cucumbers become soft and begin to deteriorate over time, that is, rot and, coming into contact with each other, quickly create an environment for the transfer of bacteria, which will lead to the spread of pathogenic microbes in all beds. To avoid this, it is worthwhile to initially seedlings at a distance of at least 15-20 cm from each other.

The lack of moisture in the soil and in the air will cause the fruit to become soft and empty inside. Heat and dry air are the main cause leading to the softness of cucumbers. You can control the humidity of the air with the help of drip irrigation, as well as regular ventilation of the greenhouse. In order for the soil to breathe and be enriched with oxygen, its upper layer must be constantly loosened.

The inconsistency of the temperature regime during cultivation can lead to the disease of the plant, and in some cases to its death.

For this vegetable culture the optimum temperature is 18-19 ° C.

The detected fungal disease in time will help to stop the further development and infection of other bushes. It is necessary to conduct preventive examinations for the presence of rottenness, discoloration, the appearance of pests.

One of the common mistakes of many vegetable growers is growing cucumbers in the same greenhouse with tomatoes. The problem is that some vegetables need one temperature and humidity, and others need one.

Tomatoes love dry air, but cucumbers may turn yellow, become soft and stop growing. Recommended from neighbors for cucumbers, Chinese cabbage, lettuce and onions.

If you feed the plants correctly and in time, the harvest will be good and generous. Carry out feeding of the bushes at least 5 times per season. Mainly for this purpose they use an organic substrate or mineral fertilizers, specially designed for this culture.

Attention! Illness in the form of rotting or changes in its density of fruits can cause a lack of sunlight.

Quite often, plants, reaching great growth, create a dome of their leaves and stems, this occurs due to improperly installed support. In this regard, the lower fruits begin to hurt.


As you can see, there are several reasons why fruits lose their density. It is important to comply with the basic requirements for the cultivation of this plant and then all the efforts and efforts will be generously rewarded with a rich harvest.
