What to do if cucumbers dry. Why cucumbers dry in the greenhouse and in the open field

    If the leaves of cucumbers began to turn yellow and dry, then you need to turn the leaf over and see if it's an aphid. Aphids feed on plant sap, so cucumber leaves turn yellow and dry. noticed chu on cucumbers - urgently take action, as aphids quickly infect healthy cucumber bushes, moving to new and fresh leaves. You can use a soap solution in the fight against it, which is sprayed on the affected plants. Can also be applied chemicals protection, such as Spark, Agravertin, Fitoverm and other aphids.

    It is possible that the leaves turn yellow and dry due to the defeat false powdery mildew (peronosporosis). This fungal disease. In order not to lose the crop, you need to take measures, for example, use drugs to combat this disease. For example, practically safe drug Phytosporin, which not only fights a fungal disease, but also additionally is a top dressing for plants. I myself use Fitosporin, and you can ask about other drugs in specialized stores.

    The leaves dry (first - wither) from lack of moisture in the heat. Usually suffer first lower leaves.

    In autumn (or already in August), the leaves dry when they are affected by diseases due to the fact that temperature regime becomes unfavorable - low temperatures.

    Insect pests can also appear on the leaves. Most effective method- spraying with insecticides, one of the safest - fitoverm.

    Cucumbers also have fungal diseases:

    Powdery mildew - treatment - Topaz drug and colloidal sulfur.

    Downy mildew, it should be treated with 0.4% oxychom, amistar, soon.

    If the leaves and cucumber tops begin to dry, then a mite pest has most likely appeared. I got my recipe from my grandmother. For prevention and treatment, she always used an infusion of onion peel. Cucumbers bore fruit in abundance until late autumn. I do this: I stuff 3 liter jar I fill 1/2 of the onion peel with water and insist for three days. For ten liters of water, I add 50 grams of onion infusion and water cucumbers from a watering can or can be sprayed. The result will not keep you waiting long. I also spray houseplants.

    The main reasons why the leaves of cucumbers in the garden can dry:

    • insufficient watering;
    • various plant diseases (one of the most common is downy mildew);

    Examine dried leaves and try to visually determine the cause. Try increasing watering and see the result.

    Drying and wilting of leaves at the peak summer season happens to many horticultural crops and the reason is often always a banal lack of moisture. Cucumber is not only a heat-loving vegetable, cucumber requires abundant watering. It seems that we are watering in sufficient quantities, because we water the cucumbers every day, but here there is one snag. Lack of water causes the plant to form root system at the very surface of the earth, and in fact we sometimes loosen the earth and this is where we damage the root system, which is why there is little water through the roots and the cucumber begins to dry out. It is correct to water not a little every day, but 3 times a week, but plentifully. The most optimal thing is when you water the plants one by one, today we water the beds with cucumbers, tomorrow we water the beds with tomatoes, then the turn of other crops comes. And then there is less work and watering is done correctly.

    I also began to dry the leaves of cucumbers, when on very hot and dry days I watered them less than once a day. Then the watering increased, and the cucumbers quickly recovered. So, if cucumber leaves dry, this does not always mean that there are pests. maybe you just need to water more frequently. Plus, cucumbers love water!

    There are many reasons for this. Here are just two of them:

    Dry leaves are caused by the Pythium fungus, which affects the entire plant - it begins to fade. Need to find root rot. This disease is exacerbated by dry soil, so make sure organic compost has been added to the soil before planting to improve drainage.

    There is a fungal disease that is caused by the fungus Vertfcillium. Symptoms include leaf wilt and Brown color stems and roots. Eventually, this disease can cause the entire plant to weaken and die. This problem often occurs in soil where tomatoes, potatoes, and other members of the nightshade family have been planted.

    The lowest leaves turn yellow and dry, and this is natural, but if the upper leaves on cucumbers also begin to dry, then this is either powdery mildew (this disease occurs due to sudden temperature changes or when you water cucumbers cold water from the tap).

    Cucumbers should be watered with water, which was collected in the morning or in the afternoon. If you water abundantly even every other day, then the leaves will stop drying.

    From powdery mildew, it is necessary to spray the plant with a special preparation for diseases.

    The most common reason for the drying of cucumber leaves is insufficient watering. Cucumbers are very fond of water, so on hot days they should be watered daily, but by no means at noon.

    Watering is carried out in the late evening or early morning.

    Fungal diseases are possible, against which Fitosporin is good.

    Perhaps an aphid has appeared, it can be seen on reverse side cucumber leaves. Fitoferm helps a lot in pest control.

    Generally, there are 2 options:

    Option 1 - not enough moisture

    Option 2 - any diseases of the plant

    Most of the time it's 1 cause. I advise you to water cucumbers 2 times a day (morning and evening), but moderately. Should help if the cause is watering.

Many gardeners to get early harvest use the seedling method of growing cucumbers. Reverent care for seedlings does not always give desired result. One of the most common problems is that the leaves begin to turn yellow. Seedlings are also susceptible to this. Why this happens and what to do - about this article.

Why can yellow or white spots appear, diseases develop, fruits fall off, stems dry up? Yellow leaves can appear for a number of reasons. You should not immediately get rid of damaged shoots, first you need to figure it out. The general picture of the state of the soil, the root system will tell you the criticality of the situation and help determine how to sprinkle cucumbers and what other activities should be started immediately. Among the main causes of yellowing leaves, gardeners distinguish the following:

  • lack of light, it does not allow the plant to develop;
  • deficiency or excess nutrients in soil (especially nitrogen and manganese);
  • violation of the irrigation regime (overmoistening or drying out of the soil);
  • growth of the seedling (there is little room for the roots in the container used for germination);
  • unstable temperature conditions;
  • the influence of toxic substances (observed when using foam and other polymers for growing seedlings);
  • plant disease disease or pests.

From what the seedlings begin to turn yellow and dry, how to save it


If the cotyledon leaves turn yellow on the seedling material, begin to dry out, then the reason lies in the new shoots with which the seedling grows. To remedy the situation, it is enough to remove extra branches or ovaries. Violations in agricultural technology are also not excluded. Experts recommend before starting seasonal work draw up a schedule of necessary activities, sow, plant and transplant, spray and fertilize in time.
The greens of the seedlings can turn yellow from low temperatures (especially with night frosts on the ground). That is why, when planting seeds on an open bed, you need to cover it at night with a film or agrotextile.
Seedlings are sensitive to the lack of useful trace elements, in particular potassium, and this must be fought. It is important to adhere to the timing of top dressing, so that developing plant enough strength and energy for normal growth.

When yellowness appears on seedlings only in a certain area of ​​\u200b\u200bthe beds, it is rather associated with an incorrectly chosen place. The problem is most likely in the composition of the soil or in the lack of light. When growing seedlings on a windowsill, it is important to prevent the soil from drying out and direct sunlight, they can burn, light shading is required.

Yellow leaves on seedlings in a greenhouse, what to deal with

When growing cucumbers in a greenhouse, the moisture and temperature regime is often violated. Excessive humidity of air and soil leads to the development of fungal diseases. The plant reacts to the deviation in external environment yellowed leaves. At first, the tips turn yellow, then the entire leaf may become covered. This signal should not be ignored.


Normal conditions for the development of seedlings provide for a temperature in the range of 22-26 degrees. If the indicator falls below 14 ° or exceeds + 42 °, cucumber shoots stop developing, and only one degree of frost leads to death. Yellowing leaves and embryos may signal a violation of the temperature regime.

Other possible reasons include:

  • insufficient pollination, as a result of which ovaries are poorly formed on the plant;
  • congestion of the shoot with ovaries;
  • damage by a fungus or insects;
  • lack of nitrogen and other microelements in the soil.

Yellowness on outdoor plants, diseases

When growing cucumbers in open ground the yellowness of the leaves often indicates a violation of irrigation: lack or excess of moisture. In extreme heat, it is recommended to water the bushes daily (morning or evening). If summer temperature moderate, it is enough to irrigate the beds 2-3 times a week. But before each procedure, it is worth assessing the condition of the soil in order to prevent stagnation of water. You should also loosen the soil in a timely manner.


If we are talking about plant damage by diseases, then yellowness or white dots on the green indicates fungal infections: fusarium, pitiosis, etc. The leaf does not respond to watering, it remains sluggish. It is necessary to treat: it is necessary to treat with special preparations, you cannot do without it. The main thing is not to lose time so that the affected area does not spread to neighboring bushes. And don't rely on folk methods, it is better to act according to science.

One of the rules for caring for cucumbers is that damaged areas should be removed to localize the problem. In the case of yellowing of the leaf, there is no need to rush, treatment is necessary here. First you need to check the temperature environment, soil conditions. This will help identify violations and correct them.

Do top dressing - improve the soil in the greenhouse


Feeding in the form of a ready-made solution

In addition to moisture and friability, the soil must be nutritious.. Growing seedlings take out most of the trace elements necessary for development from the soil. Therefore, in agricultural technology, there is a schedule for the introduction of top dressing, which enriches the environment. beneficial substances, helps to strengthen the immune system of the plant. There are two ways to introduce a useful substance. One is to spray ready solution, the second - sprinkle dry factory-made granules according to the instructions and pour plenty of water.

If the leaves turn yellow and dry around the edges, then most likely there is a lack of potassium and magnesium. And if green veins are preserved on a yellow leaf, we can talk about a deficiency of manganese and iron. In case of yellowing of the upper part of the bush, a lack of copper is diagnosed.


Granular fertilizer potassium nitrate

To fix the situation it is necessary to carry out complex feeding in a timely manner. Alternate organic with mineral, as well as root with foliar. Scheme of the introduction of nutrients:

  • for the first time, cucumbers should be fed when one leaf appears on the seedlings (ammophoska; azofoska; manure; bird droppings; herbal infusions);
  • the second time falls at the beginning of the flowering period (a solution of water and wood ash 10 l / 1 cup; potassium and ammonium nitrate 20 and 30 gr., superphosphate 40 gr. per bucket of water);
  • the third dressing is carried out during the active period of fruiting (a solution of nitrophoska 10 l of water per tablespoon of the product; a solution of 10 l of water, 0.5 l of mullein and 1 tsp of potassium sulfate);
  • the fourth dressing is used for varieties with a long fruiting period (a solution of wood ash, manure or bird droppings).

Proper watering prevents the soil from drying out

You need to correct the error in irrigation, taking into account the following factors:

  • type of soil;
  • age of cucumbers;
  • features of agricultural technology varieties;
  • weather conditions.

Important!
When choosing an irrigation system, give preference to sprinkling and drip irrigation. Dosed moisture will also prevent damage to the crop by powdery mildew, root and olive rot.


Organizing automated hydroponics for a beginner gardener will not be possible.
In open ground, it is necessary to moisten the bed more often than when growing greens in a greenhouse. Beginners should as a basis use watering rates based on one bush:

  • with a shoot age of up to 1 month, 0.5-1 l of water will be required;
  • from 1 to 2 months, the water rate increases to 1.5 liters;
  • from 2 to 3 months - up to 2-2.5 liters;
  • over 3 months - up to 3-3.5 liters.

Light and temperature, do not let the plant turn yellow

characteristic feature lack of light is the yellowing of the lower leaves on the bushes. It is impossible to change the landing site of developed bushes, so weeding should be carried out in a timely manner so that weeds do not form a shadow. Also, during the formation of the whip, care must be taken to ensure that neighboring plants do not spread on top of each other. This will not happen if the recommended scheme is taken into account when disembarking. Keeping intervals will help prevent overcrowding.
Changes in temperature also affect the color of the cucumber leaf. It is impossible to influence nature, but it will be possible to save the plant from low temperatures by building a frame and covering it with a film. If the climate is dry, then planting cucumbers should be done between corn or sunflowers. Neighboring crops will scatter sunlight, preventing greens from burning.

Errors when landing in open ground

It is often difficult to correct errors when yellowness is detected on sheets, because the reasons may lie in improper planting of seedlings or seeds. Therefore, it is important to observe the basic requirements at the beginning of the formation of beds:

  • every season change the place for cucumbers (you can return to the previous one after 3-4 years);
  • observe the distance between the holes, do not save on row spacing;
  • do not use more fertilizer than indicated on the package, excess nitrogen, for example, burns out a young plant;
  • before planting seedlings, it is hardened for at least a week;
  • when choosing neighbors, the coexistence of cultures is taken into account.

Pest control, treatments

If the bed is still attacked by pests, it is treated with insecticides and acaricides. Among the popular drugs are the following:


Prevention of yellowing, spray with nutrient mixture

  • annually change the place under the cucumber bed;
  • shoots with 2-3 leaves should be sprayed with a nutrient mixture of water (10 l), milk (1 l), iodine (30 drops) and laundry soap(20 g);
  • for irrigation, use the nutrient liquid obtained after infusion of bread with water;
  • ground surface powder wood ash not only neutralizes acidic soil, but also becomes a protection against pests.

You may not encounter the problem of yellowing at all if you follow all the rules of care and prevention in a timely manner. This is much easier than wasting strength and nerves to restore the affected plant.

One of the troubles known to vegetable growers is the drying of the ovary of cucumbers in greenhouses. The question of why cucumbers dry in a greenhouse requires an analysis of the entire growing process.

List of reasons

It happens, you wait, you wait for the harvest of cucumbers, pleasing with fresh herbs, appetizingly crispy. And they take and dry, the leaves turn yellow and wither. You look and understand, the harvest was crying.

Why is this happening? There are only two possible explanations. First, you yourself violated the rules of care, overlooked something somewhere or did it carelessly. Second, the plant was struck by a disease.

However, there is another option, you overestimate the scale of the disaster. When part of the ovaries dries up, this is only normal. After all, any plant blooms, so to speak, for the future. There are always more ovaries than it can feed. Therefore, a certain amount of them naturally dries. If just such a “natural selection” takes place in your greenhouse and some cucumber ovaries in the greenhouse have dried up, you don’t have to worry. But if the crop really dies in the bud. Let's figure it out.

Video “Causes of disaster”

From the video you will learn what can cause the drying of cucumbers.

Violations in care and cultivation technology

We will talk about the most common mistakes and shortcomings. And you remember and analyze your actions, perhaps it was one of these flaws that led to the fact that the cucumbers began to dry out.

Perhaps most often the flaws of gardeners are associated with watering. It could be:


Cucumbers love water. So it's enough to allow yourself to skip a few waterings, and the ovaries will begin to dry out. For irrigation it is good to use settled water, it should not be cold. And make sure that the water soaks the ground, and does not remain a puddle on the surface.

Mistakes made during planting harm cucumbers. Planted too densely, they begin to "starve", they lack the area for normal nutrition. This is where yellowing starts. And all you need is to carefully read everything that is written on the bag. The optimal distance between seedlings for the variety must be indicated.

Ripe fruits must be harvested not just on time - very quickly. In the characteristics of the variety, you will find the size of a ripened cucumber. Those that have reached this size must be removed immediately. Trust me, the clock counts. extra time on a branch - harm to the neighboring ovary.

It happens that cucumbers in the greenhouse turn yellow due to improper feeding. It is possible that you overexposed them on fermented mullein. Yes, at first nitrogen (namely, the mullein supplies plants with it) is especially necessary. But a fruit-bearing plant also requires phosphorus and potassium. So, at this stage it's time to add superphosphate and ash. By the way, cucumbers themselves signal what exactly they lack. Yellow spots on the leaves are evidence of magnesium deficiency. Spots of light green color appeared - potassium is urgently required.

Damage by diseases and pests

If you have not been guilty of any of the above in front of your cucumbers, the reason that the cucumbers are drying in the greenhouse should be sought in the disease. Here are the most common diseases:


There is also an attack by melon aphids or spider mites. This does not happen so often with greenhouse cucumbers, but the threat is serious - you can completely say goodbye to the harvest.

Troubleshooting

Of course next question, what to do? In both sickness and health, there is one answer: take care of your cucumbers carefully, be attentive to their needs. But this, of course, general recommendations. And when solving your specific cucumber issue, we proceed from the situation.

If you find your own among the common mistakes in care, do not repeat them. Remove dried leaves and ovaries. And remember that your miscalculations can cause serious plant disease.

Well, since you have given your cucumbers one of the above diagnoses, you need to do what is required for a certain disease.

Powdery mildew often affects cucumbers in the open field. Favorable conditions for its development are cold and moisture. Inspect the greenhouse for drafts. In addition, analyze the composition of the feed: a lack of calcium or an excess of nitrogen can cause disease. Adjust watering schedule. The soil should not be too dry or too wet.

For treatment, you can use a decoction of horsetail or marigold. If this is no longer enough, a copper-soap mixture, iron sulfate, soda with soap are effective.

Changing the composition of the soil will help fight root rot. You need to add crushed coal, ash and chalk. Spraying will be beneficial blue vitriol.

Soaking the soil with hot potassium permanganate will help to cope with Fusarium wilt. Well, in the treatment of pernosporosis, one cannot do without chemistry - for example, Bordeaux liquid. Watering and fertilizing for the duration of treatment should be stopped.

Preventive measures

The problem is easier to prevent than to deal with it, trite, but true. Pay attention to prevention, and the vast majority of cucumber ailments will bypass your greenhouse.

Adopt not-so-complicated rules:


We emphasize with a bold line: the greenhouse must be clean! Garbage, plucked leaves, other plant remains should be cleaned up immediately. The soil should be disinfected, the room should be maintained in perfect order.

And finally. Qualitative planting material- this is the key to many problems.

Video “Prevention”

From the video you will learn what can be the prevention of many diseases of cucumbers.

What to do if the leaves on the cucumbers began to turn yellow and dry

natural causes

Sooner or later, the leaves of cucumbers turn yellow for natural reasons, it is impossible to influence them. In some situations, it is possible to prevent and prolong the life of cucumber lashes.

  1. The lower leaves turn yellow and wither during the growth and development of cucumbers.. This is a natural phenomenon. The lower leaves take away a lot of nutrients. But, as the shoots grow, they no longer have enough food. Due to its lack, they turn yellow and gradually die off. To facilitate plant growth, the leaves closest to the ground are removed when there are at least 6-7 leaves on the whip. Further, every 10-14 days cut off the lower leaves. But, if the growth of the culture slows down, and new leaves do not develop, then the lower ones do not need to be cut off. The basic rule is this: if 2-3 leaves have grown, then the lower ones are removed, if not, then they should not be cut off. The cucumber must have enough green mass for the processes of photosynthesis and growth. This is especially important in a greenhouse.
  2. Prolonged cold and rainy weather. The lashes acquire a uniform yellow-green hue. This is more often observed in open ground cucumbers. If the cold is prolonged (below 17 ° C for more than 7-10 days), then the leaves of the cucumbers begin to turn yellow, dry and fall off. The only thing that can be done in this case is to put up a temporary greenhouse and feed the cucumbers. In a greenhouse, this almost never happens. When top dressing, they are restored and continue growing.
  3. Scourge completes the growing season. The lower leaves at the edges begin to dry, the leaf blade itself becomes yellow. The process begins with the lower leaves, but gradually covers all the shoots. As soon as the first signs of wilting appear, and the yield has decreased, they make top dressing with organic matter or, at worst, make a double dose of nitrogen and kalimag. Then you can extend the growing season and get a second wave of greens. If urgent measures are not taken, then the process will become irreversible and no top dressing will help - the plants will dry out.

The last two reasons are quite difficult to influence. The main thing here is not to waste time.

Improper care of cucumbers

Takes first place among all problems. The culture is very demanding on agricultural technology, and even minor deviations can lead to problems.

Wrong watering

The problem occurs with both insufficient and excessive watering, as well as watering with cold water.

  1. With a lack of moisture yellowing starts from the lower leaves and quickly spreads throughout the plant. Cucumber leaves get yellow tint. As moisture deficiency increases, they become yellowish-green, then greenish-yellow, yellow, and eventually dry out. Already at the first signs of a lack of moisture, the leaves wilt and lose turgor, become soft and rag to the touch. To correct the situation, cucumbers are immediately watered. In case of severe wilting, watering is carried out in 2-3 doses.

  2. Excess moisture manifests itself in the appearance of yellow spots on the leaves, which are barely noticeable at first, but then acquire a bright yellow color and gradually merge. Excessive watering, especially in a greenhouse, is almost always accompanied by the appearance of diseases, most often various rots. When waterlogged greenhouse cucumbers watering is stopped for 2-5 days (depending on the weather), the greenhouse is thoroughly ventilated. In open ground, cucumbers are much less likely to suffer from waterlogging, since under natural conditions most of the moisture evaporates. But with daily heavy rains, a film tunnel is made on the cucumber bed, leaving it open at the ends. Watering stops.

  3. Irrigation with cold water causes difficulty in the absorption of moisture from the soil and can lead to the death of sucking roots. In garden partnerships, water is usually taken from a well from a depth of several meters. ground water very cold and unsuitable for irrigation. Before watering, it should settle and warm up for several hours. When watering with cold water, it is not consumed by the plant, cucumbers lack moisture, cucumber leaves turn yellow. Of course, this is a temporary phenomenon, but such watering delays the development of cucumbers and leads to the fall of ovaries and greens. Cold water cools the soil, which is highly undesirable for cucumbers.

The optimal irrigation regime for a crop is once every 2-3 days, and in hot weather every day. Water consumption rate - 10 l / m 2. In cloudy and cold weather, watering is carried out every 3-4 days.


Lack of batteries

Cucumbers are consumed extremely. Their deficiency is immediately reflected in the state of cucumber leaves.

  1. Lack of nitrogen. Young leaves are small light green with yellowness, the rest become light green with a yellowish tint, the tips turn yellow. With a lack of nitrogen, the lower end of the greenery (where the flower was) narrows and bends like a beak. The opposite end thickens. Cucumbers are fed with any nitrogen fertilizer, manure (1 liter of manure infusion per bucket of water) or herbal infusion (1 liter / 5 liter of water). For hybrids, the rate of fertilizer consumption is increased by 2 times.

  2. If the leaves of cucumbers not only turn yellow, but begin to curl down and dry, this is an acute nitrogen deficiency in the soil. This phenomenon is especially common on poor soils. Zelentsy at the same time turn yellow and fall off. To correct the situation, fertilizing with nitrogen mineral fertilizers (urea, ammonium nitrate, ammonium sulfate) is carried out. Feeding is repeated after 5-8 days. The first dressing is done on the leaves (foliar), the second time cucumbers are watered under the root. With an acute lack of nitrogen, it is not recommended to feed with organic matter, since it enriches the soil, while mineral fertilizers contain elements already suitable for plant nutrition, which are absorbed very quickly. After the elimination of a sharp lack of nitrogen, they switch to the usual mode of fertilizing with organic matter.
  3. Potassium deficiency. A brown border appears along the edge of the leaf, and greens acquire pear-shaped. Top dressing with potassium sulfate or ash. Cucumbers are potassium-loving and tolerate a lot of this element, so the norms of potassium supplementation of the culture are high: 3 tbsp. spoons potash fertilizer for 10 liters of water. Ashes per 10 liters take 1-1.5 cups. The drug Kalimag is very effective, which also contains magnesium, which is also often lacking in cucumbers.

  4. Magnesium deficiency. The leaf acquires a marble color: the veins remain green, and between them the leaf plate turns yellow, but the leaves themselves do not droop, do not curl and do not dry out. It is necessary to carry out foliar top dressing Kalimag (10-15 g / bucket of water), or dolomite flour(1 cup/bucket) pour under the root.

Insufficient lighting

Suffering from a lack of light, mainly seedlings grown at home. Cucumbers tolerate shading well, but the apartments are too dark for them, and if there is no sun on the windowsill for at least 3-4 hours a day, the cucumbers turn yellow. With strong shading, the seedlings begin to turn yellow already at the stage of cotyledon leaves. Leaves become uniform yellow, and if the room is also dry, then their tips dry and curl a little. The plant itself does not die, but its growth slows down or stops altogether.


Seedlings should be grown in good light.

With a lack of lighting, seedlings are illuminated for 2-4 hours a day if it grows on a northeast or northwest window. If the window sill is poorly lit (north window) or during long cloudy weather when growing seedlings on any window sill, it is illuminated for 5-8 hours.

In greenhouse conditions, dense plantings suffer from a lack of light. The lower cucumber leaves, to which there is practically no light, turn yellow and fall off. Along with the yellowing of the leaves, diseases develop in such thickets. Usually there is not one, but several diseases.

For the normal development of cucumbers, they are thinned out, excess lashes are removed, the lower, diseased and dried leaves are cut off. Properly formed cucumbers in the greenhouse not only do not lack light, but also need shading.

In open ground, cucumbers do not suffer from a lack of light. On the contrary, they are recommended to be shaded or even grown under trees.

Cucumbers gouged

The plants initially look healthy, but the next day the leaves begin to turn yellow. If the roots are not severely damaged, then only the lower leaves turn yellow, if the damage is significant, then the leaf blades dry out and the culture dies.

If the leaves of the cucumbers have only turned yellow, then the cucumbers are watered with Kornevin (5 g of the drug per 5 liters of water) as soon as the first signs of yellowing appear and 2 days after the first watering. With severe damage, cucumbers cannot be saved.

When growing cucumbers, they are not loosened, because their roots are very tender. At the slightest damage, they die off and the plants then grow new roots for a long time.

If the soil is too dense, then it is mulched. In extreme cases, the ground at a distance of 20-30 cm from the plants is pierced with a pitchfork. But loosening cucumbers, even superficially, is not recommended.

Growing cucumbers through seedlings

Cucumber seedlings are grown only in peat pots. In no case should you dive into it. Plants are planted in the ground along with the container in which it grows.

If the roots are still damaged, then the leaves of the cucumbers turn yellow, but do not curl. Yellowing spreads evenly throughout the leaf plate. Plants are watered with a solution of Kornevin or Heteroauxin.

Yellowing of cucumbers caused by pests and diseases

Any always affect the condition of the plants. Most often, the first signs appear on the leaves, and then damage appears on greens and lashes.

  1. downy mildew. Yellow oily spots appear on the leaves from the upper side, which then merge. A white-violet bloom of mycelium appears on the underside. The spots begin to dry, the leaf blade turns brown, gradually dries up and begins to crumble. At the first signs of the disease, cucumbers are treated with Abiga Peak, Previkur, Consento, or the Trichodermin biological product. The treatment is carried out at least 2 times, changing the drug, otherwise the pathogen will get used to the active substance. Greenhouse cucumbers are especially affected by powdery mildew.

  2. Angular spotting (bacteriosis). On the upper side of the leaves appear yellow spots, from the lower side - droplets of a cloudy pink liquid. Gradually, the spots dry, crack and fall out, leaving behind holes. The leaf dries up. Then the disease passes to the greens. At the first signs of the disease, cucumbers are treated with copper preparations: HOM, copper sulfate, Bordeaux mixture.

  3. Anthracnose. It first appears on the leaves. Blurry yellow spots form on them, then merging. The leaf blade looks burnt. The edges of the leaves are slightly curled up and crumble. To prevent the development of the disease, treatment with Alirin B, Fitosporin or copper-containing preparations is carried out.

  4. Cucumber mosaic virus. Pale yellow spots or streaks appear on the leaves. Gradually, the veins become yellowish. The leaves become corrugated and gradually die off. The disease spreads rapidly and can be transferred to other cultivated plants. Farmiod treatment. With the progression of the disease, cucumbers are removed.

  5. The defeat of cucumbers spider mite . The pest causes significant damage to cucumbers. Lives and feeds only on the underside of the leaves. It pierces the skin and feeds on plant sap. Light spots appear on the leaves, which then discolor. Such points are gradually becoming more and more. With severe damage, the leaf becomes yellow-brown, dries and falls off. Initially, mites infect the lower leaves, and as they dry out, they move up the lashes. A characteristic sign of pest damage is the web with which it entangles the plant. With minor damage, they are treated with Bitoxibacillin, Akarin, Fitoverm biological products. In case of severe damage, they are sprayed with acaricides Apollo, Sunmite. All treatments are carried out only on the underside of the leaves.

  6. melon aphid attack. The pest feeds on any parts of the plant, but prefers the leaves. Aphids twist the leaves of cucumbers. They turn yellow, shrivel and dry out. If you expand the sheet, you can see a colony of insects in it. Damaged lashes dry and die, the plant begins to shed its ovaries. With a large number of aphids, it can kill the borage. For
