Withered and neglected cucumber lashes are a reason for their urgent resuscitation. From the material in this article, you will learn why leaves and cucumbers wither and what needs to be done to correct the situation.
Wrong Care
The most common cause of the poor condition of cucumber lashes is improper plant care. With proper and high-quality care, even a novice gardener can achieve a high yield.
Watering
Improper watering is the leading cause of wilting of leaves and shoots. The culture requires a lot of water, with irregular irrigation, it signals with drooping foliage and bitter fruits.
However, the soil should not be wet. Due to stagnant fluid, fungal infections, such as root rot, appear. It blocks the work of the root system, which stops the access of nutrients to the ground part of the lashes.
Without taking timely measures, the plant weakens and dies. An approximately similar picture is observed when watering a vegetable crop from a water tap.
The solution to the problem is the daily evening watering of cucumbers with warm water from a nearby barrel. You need to fill the container in the morning so that the water warms up to the optimum temperature during the day.
Watering should be moderate. The roots of the lashes are not able to absorb excess moisture. If the ground at the base of the shoots is swampy, it must be loosened. This will increase the access of oxygen and dry the soil.
The first shoots can be watered from a spoon. This will prevent soil erosion and exposure of young roots. In the spring, you can water the seedlings not only with filtered, but also with melt water.
Sediment of tap water is necessary for the settling of harmful suspensions. If the leaves of small seedlings begin to dry, they lack moisture. Seedling roots dry out very quickly. If you forget about watering, the seedlings will die.
Greenhouse plants are watered between rows. This will prevent liquid stagnation. It is impossible to water the soil abundantly in the root zone.
If desired, you can sprinkle the ground with a dry hydrogel that swells when water is absorbed. As the soil dries, it is used for other plants that need life-giving moisture.
Do not water cucumber lashes with cold water. The culture does not immediately absorb such water, it experiences a shock. We must not forget to water the plant or do it during the day in the heat under the direct rays of the sun.
Feeding
Proper development of a crop in open ground or a greenhouse is impossible without good nutrition. The plant must receive nitrogen, phosphorus and potassium. Otherwise, the green mass does not grow, lethargy, pallor, and drying of the foliage are noted.
A weak plant cannot form full-fledged succulent lashes. Its root system is already underdeveloped. It is difficult for her to absorb nutrients from the earth in the right amount.
Scourge needs trace elements. If they do not have enough manganese and iron, the formation of yellow veins is observed on the leaves.
You need to solve the problem by applying fertilizer to the roots. Top dressing is applied three times per season (dosed, in small portions). First, the plant is fed 2 weeks after picking the seedlings. The second time the roots are fed before the growing season. The third is during fruiting. To eliminate the problem, complex mixtures on an organic or mineral basis are suitable. If you want to prolong the fruiting and life cycle of the lashes, make the 4th top dressing.
Wrong landing place
Often the wilting of seedlings is associated with insufficient insolation. In many ways, the issue is decided by choosing the most suitable place. In this case, we must not forget about the timing of the transplant.
If they are ahead of them, it is difficult for seedlings to resist the influence of external factors. When seedlings are planted later than usual, the roots are damaged. Cucumber lashes are afraid of heat and the scorching sun.
In the heat, the leaves of young and fruiting plants can curl into tubules. This is due to the rapid evaporation of moisture from the surfaces of the leaves. Their twisting is an attempt to reduce the area of ββevaporation.
Lack of sunlight is no less of a problem. You can not plant cucumbers where they do not have enough sun, space, air. The thickening of the landing is excluded. In this case, you need to get rid of excess lashes.
You can not plant cucumbers in a poorly lit place. With low light consumption, the foliage fades and disappears. The place selected for the garden bed should be moderately warm.
To do this, organize a gradual cooling of the ridges. Instead of landing shelter, plastic bottles of water are laid out. They will give the plant the accumulated heat all night.
Culture is vulnerable to temperature changes. With its sharp decrease, the leaves suffer first. Due to stress, wilting occurs, the growth of shoots stops, and their death.
Bad neighbors
When choosing a place for planting cucumbers, they take into account the success of the neighborhood with a particular culture. The plant is considered unpretentious and gets along with many vegetables. But there are certain species, because of which the bushes grow small, not capable of forming a high yield.
It is not necessary to plant cucumbers in places where melons or pumpkin crops were previously planted.
You should not plant cucumbers in the beds where squash, zucchini and melons grew last year. These crops have different growing conditions.
The neighborhood with tomatoes is undesirable. Due to the developed root system, the rhizomes of the lashes will get less energy and nutrients. Do not plant strawberries nearby.
Neutral neighbors can be corn, radishes, turnips. The best are onions, cabbage, peppers, garlic. Seedlings need to be planted every year in a new place. In greenhouses, a garter of lashes is required to avoid burns when touching the walls.
Do not experiment with fragrant herbs. Basil and arugula will oppress cucumber lashes. Fennel should not be planted nearby.
Its root system will draw all the moisture and nutrients out of the ground.
Potatoes are also considered a bad neighbor. Its proximity to cucumbers will be mutually depressing. In addition to the selection of moisture and nutrients, it will shade the whips. Often affected by the same pests as cucumbers.
Much depends on the size of the greenhouse. If it is small, it is more expedient to grow only cucumbers in it, without adding other crops.
Diseases and pests
Whips wither leaves due to attacks of harmful insects and diseases. In both cases, there is a rapid progression of the problem. If you do not intervene in time, not only the leaves, but also the fruits will die within a short time.
In the care of cucumber lashes, experienced gardeners have to deal with several types of diseases.
Root rot damages the roots. Primarily, the neck is modified, then the disease spreads to the rest of the processes. The lower leaves begin to fade, the death of the bush occurs within a few days.
To suspect fuzarioz lashes can be on the fading top. Along with this, the main stem of the whip begins to rot from below. The leaves dry initially at the edges, then it spreads to the entire area of ββuXNUMXbuXNUMXbthe plates.
For cladosporiosis dark expressions are characteristic. They appear on shoots, leaves and fruits. There are no such cucumbers. And also characteristic diseases can be white, gray rot, copperhead, parasporos, powdery mildew, angular spotting.
aphid chooses cucumber lashes because of the delicious juice found in the leaves. She pierces it with her proboscis and draws out the juice, forming a honeydew that attracts ants.
Colonies of parasites spread rapidly, destroying not only cucumber, but also neighboring beds. It is necessary to get rid of aphids through chemicals, biological products, folk remedies.
spider mite prefers to feed on young seedlings, but can also affect adult bushes. Where he settles, the leaves are covered with the thinnest cobwebs.
TRIPS prefer to eat the juice of green leaves and shoots. Because of this, cucumber lashes cannot form correctly. They are bent, the foliage gradually turns white, dries up and falls off.
Most often, the cause of plant damage by fungal infections is improperly organized greenhouse conditions. There is no air ventilation in enclosed spaces, and the humidity is high.
Depending on the source of the problem, mustard infusions, solutions of vinegar, soda, soap with wood ash are used to solve it. And they also resort to spraying the lashes with effective biological products (“Fitoverm”, “Akarin”).
Spraying from diseases is carried out with a working solution based on Trichopolum and warm water. They can also cultivate the soil, previously moistened with plain water.
The tops can be sprayed with a weak solution of potassium permanganate. It will increase the tone of plants, make them resistant to diseases. Infected plants can be treated with whey, Fitosporin, Trichodermin, Metronidazole.
Preventive measures
It is not always possible to get rid of yellowness cucumber leaves. That is why it is necessary to know the methods of prevention and recommendations. You need to solve the problem after identifying the cause of the wilting of the foliage.
Preventive measures may vary. At the initial stage of cultivation, the seeds are heated. They are soaked in special solutions that promote strengthening and rapid growth.
You can not violate the rules of crop rotation. Cucumbers are not constantly planted in the same place. Seedlings are planted in those areas where suitable vegetable crops used to grow.
The picking of seedlings must be carried out in a timely manner and strictly in accordance with the scheme. Between the bushes and rows you need to maintain certain intervals. You can not plant several seeds in each hole.
It is important to remember about the timely change of depleted soil, resorting to this at least 1 time in 2 years. Distilled water is used for irrigation. Drip irrigation systems are being installed in greenhouses.
In order to prevent dense planting, pay special attention to the spacing of the bushes. Cucumber lashes after planting are stretched in length and intertwined.
In order not to reduce the access of light, no more than 1-2 seeds or seedlings with developed leaves are planted per 2 m4. When planting parthenocarpic varieties, the number of seedlings is halved.
If necessary, thin out the bushes. Get rid of extra lashes, weak shoots, fading and yellowing leaves. Pinch growth points, and improve air exchange. If necessary, shading lashes are removed along with the roots.
The correct organization of the ridges is important. If possible, they can be not only warm, but also mobile. Water bottles are covered with stones. “Battery” heat will save the plant from stress.
When arranging cucumber ridges in the open field, you can use nets for weaving. So the plants will get more air. This preventive measure will prevent stagnation of moisture at the roots.
It is necessary to provide for the care of the plant during the drought period. To do this, stock up on mulch in advance. Prepare peat, straw, humus, tree bark. If necessary, fertilizing the soil is fertilized with ash, yeast, urea.
If the lashes are planted in the sun, they are shaded by constructing sheds from improvised materials. Cardboard sheets, burlap, old sheets are suitable for this. In the evening, along with irrigation of the soil, bushes are sprayed.
Provide proper care for the whips. Exclude treatment with herbicides that can harm the crop and its yield. If they process neighboring crops, make sure that they do not fall on the foliage and shoots.
If this happens, chemicals are washed off the leaf plates. Otherwise, the leaves will become limp, turn yellow and dry. For flushing, use ordinary settled water without any additives.
Insecticides are used immediately upon detection of pests. Both biopreparations and folk remedies are suitable. In extreme cases, resort to the use of chemicals.
In case of severe damage to the lashes by pests or infections, they are disposed of. The bed is treated with a manganese solution. After that, it is used for planting other plants. It is strictly forbidden to leave diseased plants in the beds.
To quickly cope with diseases, you need to have a fungicide on hand. An effective remedy will instantly stop the wilting of foliage and the spread of the disease in the early stages of its manifestation.
You need to choose a drug for a specific type of treatment. The means are by no means universal. They have a different principle of action and dosage. Failure to comply with the instructions may result in more wilting of the lashes.
