You can lose most of your cucumber harvest not only because of the numerous diseases that affect this crop, but also because of the appearance of such a small but very voracious insect as the cotton (or melon) aphid.
The melon aphid usually settles on plantings of zucchini and cucumbers in open ground in July, and in greenhouses and greenhouses the pest can appear as early as mid-spring. Before you start fighting insects, you need to thoroughly arm yourself with knowledge about what aphids eat and how they reproduce, how to detect them, and what harm they can cause to your cucumber plantings.
Article outline
Life cycle of melon aphid
Drooping, wilting leaves and fallen flowers are the first symptoms of cotton aphid infestation. Insects first prefer to settle on the underside of the leaves, then very quickly spread to the stems, flowers and ovaries, so each time when caring for cucumbers it is important to carefully inspect the plants.
Small insects reach a length of no more than 2 mm. The color of melon aphids varies from yellow, green to dark green, almost black. Large clusters of small insects can be seen with the naked eye.
Insects overwinter on the basal leaves of weeds in the form of larvae or wingless females. In spring, aphids completely occupy the plant, and when nutrition becomes insufficient, winged individuals are born. The insect feeds on plant sap, preferring young shoots and leaves.
The aphid flies to neighboring plants, gradually reaching the melon crop. Therefore, one of the indirect agrotechnical methods of combating aphids includes regular weeding of beds. Since the process of migration of pests begins in the midst of planting seedlings, and young cucumbers with two or three true leaves can die under the yoke of this insect, it is better to worry about protecting cucumbers in advance.
What harm does melon aphid cause to cucumbers?
Death of seedlings
If action is not taken when aphids are first detected on young plants, cucumber seedlings die in 50% of cases;
Falling of ovaries and buds
Seedlings that survive an aphid attack develop slowly, and the ovaries and flowers, eaten by insects, soon fall off;
Spread of viral diseases
Aphids are a well-known carrier of viral infections, so an aphid attack is often accompanied by a painful state of cucumbers;
The appearance of ants on cucumbers
The melon aphid participates in symbiosis with ants. Ant colonies feed on sweet honeydew, which is secreted by aphids during their life processes. Such close proximity of insects is dangerous for two reasons: ants actively transfer aphids to other plants and gnaw on fruits.
Aphids reproduce very quickly: up to 10 thousand individuals from one adult female per month. Reproduction is favored by high humidity and warm weather. Thus, in greenhouses and greenhouses the most favorable conditions have been created for this insect to live. It is difficult to imagine the size of the army of aphids that will fill the entire territory of the greenhouse if its owner does not start fighting the pest in time.
Prevention of aphids on cucumbers in a greenhouse
Proper care of cucumbers in a greenhouse significantly reduces the risk of aphids. Among the preventive measures, the most effective are:
In order to respond in a timely manner to the appearance of aphids in the greenhouse, it is important to conduct regular weekly inspections of seedlings and adult plants for pests.
If during your next inspection of greenhouse plantings you find accumulations of aphids on cucumbers, you must urgently take measures to destroy the insects.
Folk remedies for aphids
The agricultural market offers a huge variety of chemical agents against aphids. However, the toxic substances of the drugs have the unpleasant property of accumulating in the fruits, remaining in the soil for a long time and limiting the period of harvesting. In this regard, to obtain an environmentally friendly harvest, many vegetable growers try to use folk remedies for aphids:
Celandine 
The collected celandine is dried and crushed, filled with water at the rate of 200-300 g of herb per 10 liters. The mixture steeped for 24 hours is filtered. The plants are sprayed generously with a spray bottle, trying not to miss a single leaf.
Garlic 
An infusion for spraying cucumbers based on garlic cloves, arrows or tops is prepared within 5 days. You will need 500 g of crushed plant parts and 3 liters of water. This method is also effective against other pests.
Ash and laundry soap
To prepare the solution you will need (50g), grated laundry soap (70g) and 10 liters of water. In addition to the plants themselves, the solution is used to treat the walls, cucumber garters, racks and crossbars of the greenhouse.
Dandelion
Pour 8 liters of water into dandelion leaves and roots in equal parts (1 kg) and leave for at least three hours. Spray the cucumbers with infusion over the entire surface of the leaves on both sides.
If, using traditional methods of fighting aphids, you have failed, you can treat the cucumber plantings with chemicals such as:
- "Arrivo"
- or " ".
Tip: Spraying cucumbers with herbal infusions will be more effective if you add a tablespoon of liquid soap or dishwashing detergent to the finished composition.
Remedies for aphids on cucumbers in open ground
In open ground conditions, more concentrated formulations are used to combat aphids:
Tobacco or shag
A plant with a tart odor will cope well with aphids. For the infusion you will need 300g of dry shag (tobacco) and 70g of tar soap. The mixture, filled with 10 liters of water, is infused for 2 days before use.
Onion peel 
Pour boiling water (7 liters) over half a bucket of husks and leave for 24 hours. Before spraying, add a bucket of water to the strained infusion.
Hot pepper 
To treat plants affected by aphids, use crushed red hot pepper in an amount of 50 g. Pour a liter of boiling water over the pepper and leave for 2 hours. Strain the finished mixture through gauze or nylon, add 10 liters of water.
When processing cucumber leaves, remember that the underside of the leaf is the favorite place for aphids. Spray the plants with any suggested composition until the insects completely disappear at intervals of 7 days.
The optimal consumption of spraying compounds for cucumbers in open ground is 1 liter per 10 sq.m.
In unprotected beds it is quite difficult to control pests, much less destroy them completely. Therefore, summer residents often use specialized insecticides. To minimize the harm of treatments, biological agents are used instead of chemical products: “Strela”, “”.
Alternative methods of killing aphids: the experience of vegetable growers
Aphids have attacked your cucumber beds and you are looking for the most effective method of counteraction? We bring to your attention practical methods for exterminating pests using folk and innovative means:
Nikolay:
“I use wormwood tops against black aphids on cucumbers. I believe that herbal infusions are the best option for treating fruit-bearing plants. I've heard that in addition to wormwood, you can use garlic cloves or tomato tops, but I don't think that's the best use for such products.
I dry and chop the wormwood, taking about 10 bushes per 10 liters of water. I leave it for several hours, you can cook it overnight and in the morning, before the scorching sun, spray the cucumbers on the leaves, shoots, ovaries, I also water the soil.”
Valentina:
“A method tested from personal experience - both to get rid of the pest and to feed the cucumbers!
Pour a liter of water into the sprayer (a sprayer with a press is required). Then, in a separate container, add half a cube of iodine to 100 ml of milk with a syringe, mix well. Pour the iodine and milk into the sprayer tank and shake the mixture with a press.
This method helps to completely destroy aphids on both cucumbers and roses. If the first time does not work, repeat the treatment with this composition after 10 days. I guarantee 100% results!."
Alexei:
“Poisoning aphids with chemical poisons is the last thing. Cucumbers are harvested daily, so it is better to use safer methods. I can recommend three options:
- Vinegar, yes, vinegar, and you shouldn’t be afraid that it will burn the cucumber leaves. The vinegar solution to get rid of aphids will be very weak. For a bucket of water – 1 tablespoon (9%).
- Coca-Cola is expensive, but effective. We replace the bottle cap with a spray bottle and spray the plantings. Why does it help? The drink contains orthophosphoric acid.
- Mix soda (70g) and any essential oil (15 drops) and pour into water (2l). Shake thoroughly and spray the cucumbers every other day. Already on the third day there will be no aphids!
I personally used all the methods, so I guarantee that it will help you too. An ash solution once helped for a greenhouse, but after experiments it became clear to me that it is most convenient to use vinegar - quickly and effectively.”
In the spring, armadas of aphids cause enormous damage to cucumber plantings in a greenhouse. Aphids on cucumbers in a greenhouse: how to deal with pests correctly so as not to lose the harvest?
Almost 1000 species of aphids known to science live on European territory. These pests not only suck the juice out of plants, but also spread diseases, especially viral ones, for which there is no cure. Pathological growths on various plant organs (galls) are formed after plants are infected by aphids.
Aphid. Adult All aphids reach a small size - only a few millimeters. The body of aphids is colored in different colors: there are pests with a straw color, black, green, to match the color of branches and leaves. The pest has a proboscis that is fully adapted to piercing leaf blades to suck out juices.
Having settled on plants in a greenhouse, aphid colonies can irreparably damage cucumber vines in a short time. The leaves become withered and droop. The plant stops developing, blooming and bearing fruit. The pest secretes sugary juice, the so-called “honeydew,” which contaminates and sticks cucumber leaves together. Other vegetable pests also flock to the sugary secretions of aphids.
If ants appear in the greenhouse, then aphids will definitely appear. The honeydew is especially attractive to ants, which live in symbiosis with aphids and are ready to “milk” it around the clock, waiting for something sweet. Ants take on the role of aphid protector, transfer the pest to new areas, infecting all the plants around. It gets to the point that ants provide aphids with shelter in their own anthill during the winter.
Advice! At the first signs of pests appearing in a greenhouse with cucumbers, it is necessary to immediately begin the comprehensive destruction of aphids and ants.
Aphids have two developmental phases - wingless and winged. Wingless individuals ensure the reproduction of the colony and an increase in the number of new pests. Pests in the winged phase move sufficient distances where they find new objects to feed on.
Advice! It is useful to release ladybugs into a greenhouse infested with aphids.
A ladybug released into a cucumber greenhouse can destroy up to 50 aphids per day. In the stage of a voracious larva, a ladybug during its existence is capable of destroying up to 800 pests. They also feed on aphids and other insects: gall midges, lacewings, aphidius, and lysiflebus. These insects can be used to kill aphids in closed greenhouse areas.
Preventive techniques to prevent the proliferation of pests in a greenhouse with cucumbers
Qualified and timely care of cucumbers helps ensure the development of healthy plants in a greenhouse. Agrotechnical measures for growing cucumbers in closed ground help to harvest an excellent harvest of vegetables from healthy plants.
It is very important to follow the rules for watering cucumbers in a greenhouse. 
Traditional methods of combating aphids on cucumbers
Preventive techniques that are used to protect planted cucumbers from aphids are designed to prevent or contain the appearance and proliferation of pests. But these measures do not always achieve a positive result. Despite all the measures taken, aphids can infest the greenhouse in a matter of days.
If aphids are not controlled, they will infect all plants in a matter of days. Pest control can be carried out in two ways: chemical or folk remedies. Both methods have their pros and cons. Chemical treatment of cucumbers indoors gives faster and more effective results, but the accumulation of harmful substances occurs in the fruits themselves. To begin with, you can try to get rid of aphids on cucumber bushes using folk remedies; fortunately, there are many recipes for this.
Laundry soap is a proven means of pest control in a greenhouse. Spraying is carried out periodically throughout the season, until the cucumber plants are destroyed. This helps to curb the growth of aphid colonies, but even a short break in treatments can cause rapid reproduction of insects and the death of cucumber vines.
Chemical method of controlling aphids on cucumbers in greenhouses
It is allowed to use chemicals to control aphids on cucumbers in cases where the pest has multiplied in large quantities and there is a real threat of plant death. Chemicals guarantee high results in killing pests, but failure to comply with the rules for using the drug can lead to poisoning.
If folk remedies do not help, then turn to chemicals The most effective preparations for aphids on cucumbers in protected ground are: “Decis”; "Inta-vir"; "Kinmiks"; "Arrivo".
These drugs are diluted according to the instructions provided by the manufacturer. It is necessary to comply with the deadlines for harvesting fruits after the last treatment.
Once again about ants
Any manipulations to treat greenhouse areas against aphids using folk remedies will not achieve the goal unless the ants that spread aphids and multiply the infestation are destroyed. There are a number of chemical preparations for killing ants that effectively help gardeners get rid of insects: “Thunder”; "Mashenka"; "Ant-eater"; "Absolute".
At the same time as anti-aphid agents, do not forget to use anti-ant drugs. The use of chemicals should be combined with constant loosening of the soil in the greenhouse. The underground passages of the ant labyrinth crumble when the soil is loosened. Insects are busy constantly restoring their communications. Entrances to anthills can be filled with: ground hot pepper, mustard powder, ash, saltpeter, lime. A lime solution (100 g per 1 bucket of water) can be used to fill the entrance to the ant’s home.
Good results are obtained from repelling insects with herbs: parsley, basil, mint, lemon balm, wormwood.
Garlic or garlic infusion helps perfectly in the fight against ants.
How to defeat aphids and ants in a country greenhouse: video
Simple enough spray the bushes affected by aphids with a soap solution(200 g per 10 liters of water).
For ease of execution just chop it into small chips and wait until they dissolve in water. It can also be used for prevention.
You can use the soap solution either on its own or together with ash or onion peels.
Another advantage of using laundry soap against aphids is the product is completely harmless to humans.
Green soap
Green soap for aphids is widely used in gardening. In addition to protecting trees and preventing plant diseases green soap effectively helps to get rid of or prevent the appearance of sucking ones, namely aphids.
How to prepare a soap solution for aphids? You can prepare a solution at the rate of 200-300 grams per 10 liters of water or prepare a mixture using 20 grams of mustard powder, 200 grams of Green soap and 9 liters of water. While stirring the prepared solution, pour copper sulfate (20 g per 1 l) into it.
Experts advise treat plants during their active growth no more than 3 times per season. Soap solution against aphids is excellent against pests.
Ash
Wood ash is not only a universal fertilizer, but also a good remedy for aphids. In this case, an ash solution is used. For it you need to boil 300 g of sifted ash for 25 minutes, then strain and add 10 liters of water.
When apple aphids appear on your trees you can “powder” the leaves, pre-wetting them for better adhesion.
Following the opinion of experts, aphid ash is also the best remedy to prevent the appearance of aphids.
Ash contains a high percentage of potassium, so by adding it to the soil and increasing the potassium ratio, you automatically eliminate excess nitrogen, which is one of the main reasons for the appearance of aphids. The required dose for an adult tree is 5 kg per year. Ash against aphids will be an effective method of killing insects.
Ash-soap solution
For the solution you will need 1.5 kg of ash and 50 g of Green soap. Dissolve all this in hot water and let it brew for a while. In most cases, the solution is used to control pests, although it is a reliable feeding agent.
On ordinary days spray plants every 10-14 days, but during the mass appearance of pests, this must be done more often - once every 5-7 days.
The effect of this remedy will be more effective if you do not start the situation and use it as soon as the annoying bugs appear.
An infusion of aphid ash is an effective pest control solution. We'll talk about fighting aphids with vinegar next.
Vinegar
Many people ask the question: “Does a vinegar solution help against aphids?” Aphid vinegar has many fans among gardeners. Some argue that fighting aphids with vinegar, using it only 2-3 times, will help you forget about the existence of aphids in your garden or garden.
To prepare the solution you only need 1 tbsp. l. vinegar and 1 liter of water. When using vinegar essence take 1 tbsp. l. for 10 liters of water. Vinegar against aphids is one of the best means of control. Spraying with vinegar against aphids should be carried out systematically. More on mustard and the fight against aphids with its help.
Mustard
Ants are often the cause of aphids. To get rid of them You can use a product that they don’t particularly like - mustard against aphids.
Sprinkle dry store-bought mustard in areas with the largest concentrations of ants and perhaps the next day they will already be gone. Thus, mustard against aphids is an excellent means of pest control.
This method can be used also for prevention, unless, of course, you have pets walking around the yard.
Another option for using this product is a solution (100 g of powder per 10 liters of water). Spray the bushes as pests appear. Read more about iodine for aphids.

(from Latin Aphidoidea) is a parasitic, plant sap-sucking insect belonging to the order Hemiptera. Pests multiply quickly and can cause the death of one plant or an entire planting, which will lead to a decrease or even complete loss of yield.
Methods for controlling aphids on cucumbers are divided into folk and drug methods. Using recipes tested by many gardeners, in combination with proper care and preventive measures to protect against pests, you can greatly reduce the likelihood of plant damage.
Treatment of cucumbers against aphids with chemical and biological preparations
It is not difficult to determine the presence of aphids on plants. It is enough to unfold a damaged, curled cucumber leaf, and you will see small black, light green, or transparent bugs inside, the length of which does not exceed 2-3 mm.
The primary cause of aphids appearing on a site is garden ants. First you need to get rid of them, and then fight the pest. Preparations for killing aphids are divided into 2 types:
- chemical;
- biological.
Chemicals for controlling aphids on melons and melons
The most effective and safest products in this category are Acrofit and Intavir. They do not harm pollinating insects, pets or humans, and do not damage surrounding plants.
Cucumbers are treated with Acrofit using a sprayer according to the instructions. You should choose a sunny day without precipitation, since the drug needs 8-10 hours to be effective. It is better to carry out treatment in the morning. Spraying should be repeated after 10 days. Do not use the drug 2 days before harvest.
If you find that black aphids have appeared on cucumbers, control measures can be limited to the use of Intavir. The tablet should be dissolved in 10 liters of water and sprinkled evenly on both sides of the leaves.
The remains of the drug cannot be stored, so all plants in the area affected by the pest should be treated in one day. Spraying is carried out in the morning, in sunny weather. Maximum number of treatments per season: three, with an interval of at least 14 days.
Biological preparations against aphids
The substance is prepared according to the instructions. Spray cucumber bushes in clear weather. During the growing season of plants, 2-3 treatments are carried out with an interval of 20-21 days.
Fighting aphids on cucumbers with folk remedies
The most effective folk remedies for combating aphids on cucumbers are infusions of aromatic plants. Also often used in recipes is soap solution and vinegar. Any infusions and solutions must be used 2-3 times per season, with an interval of 10-15 days.
Recipe for ash solution with laundry soap
To prepare, you will need 2 tablespoons of wood ash, a piece of grated laundry soap and a bucket of water. When all the ingredients are completely dissolved, carefully treat the leaves (especially the lower part) with the resulting mixture.
Treating cucumbers against aphids with vinegar
You should use 9% table vinegar: dilute 2 tablespoons in 2 liters of water, and spray the plants every 3 weeks during the growing season.
Recipes for herbal infusions for treating aphids
Among gardeners who care about the nature and ecosystem of their plot, treating cucumbers against aphids with folk remedies using strong-smelling plants is especially popular. To get rid of sucking insects and ants, celandine is used: 0.3 kg of sun-dried leaves are infused for 2 days in a bucket of water.
When choosing what to water cucumbers against aphids, slugs and caterpillars, they most often give preference to garlic: 0.5 kg of crushed raw materials are placed in a three-liter container with water, kept for 5 days in a warm room, the finished infusion is filtered and the volume of liquid is brought to 10 liters.
Hot pepper will help get rid of ticks and aphids: 50 gr. crushed pepper is infused in 1 liter of boiling water for 2 hours, filtered and the volume is adjusted to 10 liters.
The consumption rate of herbal infusions is 1 liter of the finished substance per 10 square meters. m landing.
How to protect cucumbers from aphids in a greenhouse
Fighting aphids on cucumbers in a greenhouse In closed ground, the same methods of fighting aphids are used as in open beds. When using chemicals, you should protect your respiratory tract and skin, and after treatment, close the doors and windows of the greenhouse tightly (to protect pets and poultry).
If aphids were found in the greenhouse during the season, then in the fall you should:
- destroy plant debris;
- replace the top layer of soil;
- thoroughly wash the internal surfaces of the greenhouse with a solution of copper sulfate;
- treat the greenhouse with a sulfur bomb.
Preventive protection of cucumbers from aphids
Simple preventive measures will help prevent the appearance of aphids on cucumbers:
- regular weed removal;
- compliance with agricultural technology and planting rules (sufficient distance between bushes);
- cleaning up plant debris in the fall and tilling the soil;
- fight against garden ants;
- attracting birds to the site (using feeders and drinkers);
- Planting dill and mustard greens next to cucumbers will help attract ladybugs that feed on aphids.
Aphids are a large group of insects. It has about 3 thousand species. Over time, scientists discover new species of aphids. Almost every plant can be damaged by some type of this pest, including cucumbers.
It is not uncommon for gardeners to discover yellowness on cucumber leaves. Gradually the leaves curl and fall off. Culture growth slows down significantly or stops altogether. Small insects can be seen on the inside of affected leaves and may be almost transparent and light or dark green. This is an aphid that, without timely control, can destroy the entire crop of cucumbers.
Reasons for appearance
Biologists believe that aphids exist in close symbiosis with ants. And it gets to the plot with cucumbers thanks to the ants. They feed on the waste product of aphids - honeydew (honeydew). It is a sticky and sweet liquid.
Aphids that live in a garden or greenhouse are often called melon aphids. The danger is that it can destroy the entire plant, covering both young shoots and the ovary and flowers. The insect pierces the flesh of the crop, drinks the cell sap and secretes poison. Under its influence, the leaves begin to curl. In such an improvised “house”, aphids live and reproduce. Here it is reliably protected from birds and other insects that eat it. Aphids can also spread various viruses. As a result, cucumbers are affected not only by insects, but also by viral diseases.
Description of the pest
The melon aphid has a length of 1.2-1.9 mm. The shade can range from almost transparent greenish-yellow to dark green. In winter, insects hide under the root foliage of weeds. When the air temperature warms above +5 o C in spring, aphids awaken and begin to reproduce. The pest forms entire clusters on the underside of weed leaves. Insects reproduce very quickly (up to 20 hatches during the season). When the colony reaches such a number of aphids that there is little space on the weeds and there is a lack of food, the insect flies to other plants, giving preference to melons. During this period, young leaves already appear on the cucumbers, which become an ideal place for a further population of aphids.
When starting the fight against aphids, it is necessary to simultaneously fight the ants living in the garden bed.
Effective methods of control
Melon aphids multiply especially quickly in warm weather and high humidity. In addition to cucumbers, this pest also affects dill, zucchini, squash, pumpkin, carrots, and eggplants. Therefore, it is undesirable to plant these crops close to each other.
In order for pest control on cucumbers to give a positive result, it is necessary to test one or another selected product in a small area. After achieving the desired effect from application, you can treat the entire area with cucumbers. It is better to carry out processing in the evening. Under the influence of ultraviolet rays during the day, drugs lose their toxicity.
Chemicals
Before planting cucumbers, it is advisable to disinfect the soil with the help of, which will serve as a preventive measure to combat the pest. But if the aphids have already appeared, you can use these drugs no later than 3 weeks before harvest (before the ovary appears). This is due to the high toxicity of insecticides.
Insecticides for aphids:
- Metaphos;
- Decis;
- Karbofos;
- Inta-vir;
- Kinmiks.
Foliar fertilizers, which consist of 10 g of calcium chloride and 20 g of superphosphate per 10 liters of water, have a gentle effect on the plant. The resulting solution is sprayed on the lower part of the foliage. The plants are treated again after 6-7 days. This product will also help fight ants. Treatment of cucumbers with chemicals must be carried out with regular loosening of the soil.
Important! We must not forget about health safety when processing cucumbers with chemicals. After spraying, face and hands should be washed thoroughly.
Biological products
First of all, you need to pay attention to drugs that are safer for human health. These are biological agents, after using which cucumbers can be eaten within 1-2 days. These include:
- Aktofit;
- Fitoverm;
- Arrow;
- Bitthoxybacillin.
Plants that repel aphids
It is very useful to plant plants in the garden with cucumbers that repel pests:
- mint;
- marigold;
- thyme;
- sagebrush;
- thyme.
You can plant mustard or dill near the cucumber bed. Ladybugs, which eat aphids, love them very much.

Folk remedies and recipes
The safest methods for fighting aphids are folk remedies. Those who prefer organic farming refuse to use chemicals and replace them with products based on natural ingredients. They do not pollute the soil with harmful substances and do not harm human health.
Proven recipes:
- Dissolve 300 g of ash and 50 g of laundry soap without additives in a bucket of water. Leave the solution for 24 hours. Spray cucumbers affected by aphids.
- Pour 300 g of dried celandine into 2-3 liters of boiling water. Let it brew a little. Then add another 7-8 liters of hot water. Let it sit for 2 days and use it for treatment against aphids.
- Pour 0.5 kg of green dandelion leaves into 10 liters of hot water. Leave for 3 hours and spray cucumber seedlings.
- Pour 1 kg of tomato tops into a bucket of water. Leave for 4 hours. Boil the infusion and leave for another 3 hours. Add water, increasing the volume of liquid by 2 times. The product is ready.
- Finely chop the garlic and place in a glass jar. Add the same amount of water. Seal tightly and leave for 10 days. Dilute 25 ml of the prepared product in a bucket of water and spray the plants affected by aphids.
Folk remedies may not cope with insects if the area affected by aphids is very large. You need to start treating plants when there are not too many pests yet. The products must be freshly prepared, as they quickly lose their quality.
To keep plants healthy, timely and qualified care is necessary. To prevent cucumbers from becoming infected with aphids, preventive measures should be taken.
Adviсe:
- Disinfect the soil and equipment with lime chloride (400 g per 10 liters of water) before planting.
- Water the cucumbers with water +23-25 degrees. When the air temperature drops, reduce the amount of watering.
- Inspect the seedlings every week to be able to detect aphid damage in time.
- Provide good air flow in the cucumber plot and get rid of weeds.
- Fertilize the soil in a timely manner.
