Why do cucumbers grow crochet in a greenhouse and open field: what is missing

The growth and quality of cucumbers are directly dependent on many factors affecting the crop from the environment. Most often, this effect is reflected in the appearance of vegetables, which is why many gardeners wonder : why do cucumbers grow crochet in a greenhouse? In order to prevent the development of crooked fruits in your garden, you need to know about the reasons that cause this phenomenon.

Irrigation method

Most often, cucumbers curl due to improper watering.

There are several incorrect watering practices that every summer resident should avoid when growing cucumbers in a greenhouse:

• Irrigation using cold water, due to which fruit deformation begins. A relatively stable temperature of the soil and air is established in the greenhouse, which creates a favorable microclimate for the growth of a he althy plant. If cold water regularly enters the soil, the roots of the plant crop become cold, the plant begins to redistribute all the accumulated resources to neutralize the damage received, as a result, the fruits turn yellow and curl.
• Insufficient amount of water used for irrigation leads to moisture deficiency. Cucumbers are plants that are very sensitive to soil moisture. During the period of aridity, they begin to spend the minimum amount of resources for the formation of fruits, which, as a result, twist and decrease in size.

• Excess moisture is also detrimental to cucumbers.In this case, crooked cucumbers in the greenhouse appear due to the processes of rot formation on the roots of the plant. Also, the plant culture loses the ability to fully extract the necessary substances from the soil, as they are washed out with a large amount of water.

If the summer resident does not know why cucumbers curl, the first thing to pay attention to is watering the plant. If, however, a sufficient amount of moisture is introduced into the soil that meets the characteristics of the microclimate that has developed in the greenhouse, and the shape of the cucumbers continues to resemble a hook, then it is necessary to look for other factors that cause such a pathology.

Late harvest

Many summer residents think like this: "I will begin to harvest when a sufficient number of cucumbers of the required size ripen on the bush." It is worth considering that late harvesting is the wrong approach to summer cottage business, since fruits that have been in the garden for a long time not only become crooked, but also lose their taste, rot, and are damaged by insects.Also, large pear-shaped cucumbers can greatly interfere with the formation of other fruits, which is why vegetables begin to deform their structure at the stage of their formation.

To avoid this, you need to pick cucumbers every 2-3 days when they grow to medium size. This approach will increase the duration of the fruiting period of the bush, not only in the greenhouse, but also in the open field.

Fertilizers

Why do crooked cucumbers grow for no apparent reason? The ratio of mineral and organic substances in the soil has a huge impact on the development of plant culture and the formation of fruits. Moreover, both a lack of fertilizers and their overabundance can cause curvature in vegetables. Deficiency can lead to not pronounced deformation:

• phosphorus;
• iron;
• copper;
• nitrogen.

At the same time, the lack of these substances also causes yellowing of the leaves, loss of taste characteristics of the fruits.

They highlight a more obvious reason for getting a crooked cucumber harvest associated with top dressing. In a greenhouse, cucumbers will deform their shape due to a lack of potassium. Potassium is leached out of the soil due to the use of fertilizer made on the basis of yeast, herbal infusions, the use of chicken manure, mullein as top dressing.

If you regularly feed crops with the listed fertilizers, bushes become sprawling, and the size of cucumbers decreases to tiny.

Another reason why cucumbers are irregularly shaped is that they are planted in an area where zucchini, pumpkin or dill used to grow. This is due to the fact that the listed plants leave only a small amount of nutrients in the soil, which cucumbers lack for active growth and fruiting.In order not to get a crop of crooked cucumbers, fertilizers must be introduced into the ground before planting them. How to feed the soil for cucumbers? It is best to use fertilizers as a top dressing, which include potassium, phosphorus, iron, copper or nitrogen. However, they should be introduced in moderation, without creating an overabundance.

Lack of light and heat

Cucumbers are often twisted due to lack of heat and light. In order for cucumber fruits to be even, they need to create an ambient temperature that is optimal for growth, which is set within 23-26 degrees Celsius. With special care, such a temperature regime must be observed during the final phase of flowering. When the temperature in the greenhouse exceeds these figures, the fruits of cucumbers become shriveled, begin to curl from drying out. If the temperature is lower, the plant quickly becomes ill and begins to produce dense, but bent vegetables.

Light deficiency can be caused by cloudy weather, thickening, improper greenhouse design. The lack of lighting caused by any of the listed reasons negatively affects the vegetative processes and photosynthesis. As a result, cucumber fruits are bent. If cucumbers grow strongly in the greenhouse, they need to be stepson, pinch the bushes, and thin out the foliage. Such procedures will help to avoid thickening of plantings and lack of lighting.

Neighbourhood of different varieties

Cucumber cultivars, which form fruits in the absence of pollination, do not coexist badly with ordinary or hybrid varieties planted in a greenhouse structure. The need for such isolation of parthenocarpic cultivars is due to the fact that the pollen of hybrid plants spreads and contributes to the disruption of the function of the formation of fruits of cucumbers that do not need pollination. Because of this, crochet cucumbers appear.

What should I do to avoid such a situation? In order for even cucumbers to grow in the greenhouse, it is necessary to plant plants of the same variety in it.If the summer cottage is small enough and does not allow the construction of several greenhouses, hybrid and parthenocarpic varieties should be planted at different ends of the greenhouse space. If the greenhouse is small, it is necessary to limit the contact of these varieties. This can be done by covering part of the bushes with cloth.

Some summer residents grow cucumbers in the same garden for a long time, which can also affect the quality of the fruit. Why do vegetables turn yellow and curl in this case? The fact is that with such a landing, the risk of fungal pathologies increases. Also, the question of why cucumbers are crooked can be answered by the fact that during long-term cultivation of such crops, colin accumulates in the soil in one place - a toxic substance that disrupts the process of fruit formation, which, in particular, affects their shape.
