What to do if the cucumbers wither in the greenhouse?

Growing cucumbers on their site, gardeners face various problems. One of the most common is plant wilting. In order not to lose your crop because of this, it is very important to understand the essence of the problem and start saving your beds.

Bad conditions

Most often, cucumbers begin to wither due to the fact that they grow in the wrong conditions.

• Heat. The state of cucumbers is negatively affected by an overabundance of the sun. So that the cucumbers do not fade, the beds should be carefully shaded. For this purpose, you can use pieces of cardboard or unnecessary bags. In addition, greenhouses must be regularly ventilated. It is best to do this in the morning or evening.
• High humidity. High humidity also negatively affects the state of cucumbers growing in greenhouses. Regular ventilation also helps to solve this problem.
• dense plantings. Another reason for the wilting of cucumbers is thickened plantings. In such conditions, plants do not have enough free space. Because of this, they wither and die. To prevent this from happening, seedlings are recommended to be planted at a distance of 40–60 centimeters from each other. When the seedlings grow up, they can be thinned out. In this case, some plants will not interfere with others.

In general, creating suitable conditions for growing cucumbers in a greenhouse is very simple.

Mistakes in care

When caring for young plants, many novice gardeners make certain mistakes.

• Improper watering. For normal development, cucumbers need a sufficient amount of moisture. Without this, the soil dries up, and the plants’ immunity is significantly weakened. To prevent this from happening, the soil must be regularly moistened. In this case, do not water the plants too abundantly. This will lead to root rot. In addition, gardeners are advised to use warm and well-settled water for irrigation.
• Errors when applying dressings. For normal development, cucumbers need to receive enough nutrients. You can feed green plants with both organic and mineral fertilizers. In this case, do not use too concentrated solutions. It can also lead to leaf wilt and crop death.
• Use of concentrated top dressings for spraying on the leaf. If such products fall on the surface of the foliage, it begins to fade. In the process of preparing dressings, you must strictly follow the instructions.
• Insufficient pollination. This is one of the rarest causes of wilting cucumbers in a greenhouse. If plant varieties pollinated by bees were chosen for planting indoors, doors should be opened regularly during flowering. In this case, insects will constantly have the opportunity to fly into greenhouses. You can attract their attention by spraying your beds with sweet solutions. If a self-pollinating variety was chosen for planting, the plants should be gently shaken several times a day during flowering. In addition, some gardeners gently transfer pollen from one flower to another with a brush.

In general, plant care should not be given too much attention.

Diseases and pests

Common diseases can also lead to wilting of cucumbers.

• Root rot. The first sign of the disease is the drying and wilting of the lower foliage. You can only notice this during the day, because in the evening the plants adapt to the cold. To combat this disease, infected sheets must be removed and burned. After such a procedure, cucumbers should be treated with “Fundazol” or any similar preparations. Instead, you can also use Fitosporin. The beds in the greenhouse are treated with them several times. The interval between procedures should be at least ten days.
• Fuzarioz. The disease is also known as Fusarium wilt. If the tops of the cucumbers withered, and the stems began to rot, then the plant is sick. This disease can destroy more than half of the crop. To prevent this from happening, infected plants must be removed and burned. Treatment of diseased plants will no longer help.
• White rot. This disease most often affects cucumbers growing in a greenhouse. This usually happens during the period of active fruiting. The foliage of infected bushes becomes soft. Over time, dark spots appear on it. For the treatment of this disease, it is recommended to use proven fungicides. From time to time, drugs need to be changed.
• Peronosporoz. Downy mildew is another disease that can greatly harm cucumbers growing in a greenhouse. Yellow spots appear on the foliage of sick cucumbers. At the same time, she begins to fade. Over time, the spots increase, and the green mass dries up. All this quickly leads to the death of plants. You can stop the spread of the disease using copper sulfate or Bordeaux liquid. If these products do not help, the area can be treated with fungicides.

Various pests also pose a danger to cucumbers.

• aphid. These are the most common pests that attack plants immediately after planting. You can see them on the inside of the sheets. To get rid of them, plants are treated with soapy water. Instead, the beds can be sprayed with infusions of potato tops, tomato leaves, and marigolds. It is best to do this in the early morning or evening. To avoid the appearance of a pest, spicy herbs or flowers can be planted in greenhouses next to cucumbers. This will definitely benefit the plants.
• spider mite. This pest is also able to significantly weaken young cucumbers. You can notice traces of his activity by examining the back of the sheet. At this time, it is covered with a barely noticeable cobweb. To combat these pests, concentrated onion infusion is used. If there are a lot of insects on the site, the home remedy can be replaced with purchased insecticides.

The rest of the pests do not pose a particular danger to plants in the greenhouse.

Preventive measures

To avoid wilting cucumber foliage, gardeners should adhere to the rules listed below.

• Observe crop rotation when planting cucumbers. This culture cannot be placed in the same place for several years in a row. The best predecessors for cucumbers are zucchini, pumpkins and legumes. Such plants do not deplete the soil.
• Mulching beds after planting. This procedure allows you to save moisture in the soil. In addition, cucumbers growing in a greenhouse remain protected from weeds. This means they get more nutrients. For soil mulching, it is recommended to use dry grass or peat.
• Do not use herbicides. This can harm plants and weaken them. It is not worth using herbicides not only for processing cucumbers, but also for spraying other plants on the site.
• Form bushes. Grown plants are very important to properly form and tie up. Under such conditions, cucumbers are less likely to get sick. Plus, it’s easy to take care of them. Metal and wooden supports should be treated with special protective equipment before use.
• Water the beds regularly. Preventing cucumbers from wilting is much easier than dealing with this problem. Plants in the greenhouse need to be watered from the moment the seeds or seedlings are planted in the greenhouse.

With proper care, greenhouse cucumbers will stay healthy and strong.
