A common problem for many summer residents is the partial or even complete death of the cucumber crop. Therefore, the question of why cucumbers die in the greenhouse and how to prevent this is still relevant. Growing perfectly well-groomed crops that will yield 100% of the harvest is a problematic task to complete. Cucumbers are a delicate crop that is susceptible to external factors, so newcomers have a lot of trouble with it.

Causes of death of cucumber bushes and fruits

Withering leaves and twisted fruits are a problem not only for beginners, but also for experienced gardeners. There are many reasons for this behavior, so greenhouse owners need to understand in more detail what violations were made during the preparation of the beds, planting crops and daily care.

Common problems:

  1. Fungal diseases are the primary attack that affects garden crops, including cucumbers. White rot quickly spreads through the plant, softening the tissues and turning them into mucus, as a result of which the cucumbers die. The crop either does not grow at all, or its amount is minimal.
  2. All crops suffer from pests, if you do not pay attention to the fight against them. Today, the agricultural market offers various means to combat aphids, whiteflies and other harmful insects. One has only to choose the appropriate drug and carry out the treatment according to the instructions.
  3. Root rot begins to manifest itself even before the bushes begin to bear fruit. It can appear during the period of fruit formation and during fruiting. This disease indicates that the gardener made some mistakes in the selection of planting material. A violation of the pre-sowing preparation of seeds is also possible.
  4. Improper gardening is a common problem faced by novice vegetable growers. Without experience, the gardener can build too high a bed, and this is fraught with rapid evaporation of water. As a result, the cucumbers disappear, as they do not have time to receive a sufficient amount of moisture.
  5. Failure to comply with the temperature regime is another mistake of inexperienced summer residents. It must be clearly understood that cucumber is a thermophilic culture that reacts painfully to temperature changes. If the greenhouse is not properly heated, the leaves will begin to fade first, and then the death of the crop may follow. This problem can be easily eliminated by adjusting the temperature balance in the greenhouse.

Knowing about the possible occurrence of such problems, the summer resident can take the necessary measures to obtain a bountiful harvest.

About pests and diseases

Common pests that attack and spoil planted cucumbers are aphids and greenhouse whiteflies. Insects devour not only the leaves, but also the roots. You can get rid of them without resorting to store products, but using simple materials at hand:

  1. To get rid of a whitefly, all you need to do is find a piece of plywood, paint it yellow, and then cover its surface with a sticky substance. The yellow color attracts this pest, and when it crouches on a sticky surface, it becomes trapped.
  2. To get rid of aphids, you can make a 1:10 solution of garlic.

Most often, the cucumber suffers from downy mildew, root and gray rot:

  1. Powdery mildew appears as white spots on the leaves of the plant, which grow over time, the leaves themselves begin to turn yellow, and the plant dies.
  2. Downy mildew also appears as spots on the leaves of the cucumber, but only in a green tint. They grow, turn yellow and cause the plant to dry out.
  3. Rot of the root system appears when the seedlings are planted incorrectly, when the plant is watered with too cold water. As a result of such actions, cracks appear on the roots, and the plant dies.
  4. Gray rot can be detected by greyish spots on the stem and leaves. They are the result of freezing of the soil and poor ventilation of the greenhouse.

Important! To prevent diseases of the cucumber, it is necessary to carefully look after the plant and not allow any deviations from the established norms.

How to equip a greenhouse so that cucumbers do not fade

In order for the cucumber seedlings to quickly take root in a new place, you need to think about how to properly process the soil, it is its quality that will affect the growth of the culture and its further fruiting.

Therefore, all the soil in the greenhouse must be properly dug up, weeded out, all remnants of previous plants removed, and then fertilized correctly.

Fertilizing the soil is an important point, since minerals and other beneficial trace elements will saturate the soil and provide proper nutrition for young cucumber seedlings.

Do not forget about the fumigation of the greenhouse room, which will disinfect the space and ensure the safe development of the cucumbers. This can be done immediately after planting the seedlings. Fumigation will get rid of pests and other microorganisms that can harm the cucumber. To carry out proper fumigation, all doors and windows in the greenhouse must be tightly closed. After that, you need to take kerosene, lump sulfur, put it all in a container and set it on fire.

Heating in a greenhouse is an equally important point, the right temperature will ensure an excellent harvest of cucumbers. Here you need to take into account the characteristics of a particular variety.

For greenhouse planting, all early-maturing varieties and some hybrids are suitable, for example, Suomi F1, Saratov F1 and Valaam Hybrid.

The most important thing is to remember the rules of care and love your job, then young seedlings in the future will give a tasty and bountiful harvest.
