Cucumbers can be grown vertically on trellises. The second method has long and successfully been used in greenhouses, it saves usable space and reduces the risk of infection of plants with infectious diseases.

For cucumber bushes to grow well and bear fruit, they need:

  • heat;
  • high humidity;
  • nutrients.

When arranging a greenhouse, it is better to orient it from east to west, so the plants inside will be provided with the maximum amount of light. On the north side, the beds should be closed from the cold wind.

Watering the cucumbers should be regular, at the same time, you need to make sure that the cucumbers are not rooted in the swamp.

Cucumbers respond very well to leaf and root feeding. Fertilizers are applied at least once every 10-14 days.

This garden culture does not tolerate too high summer temperatures in the southern regions, so you should immediately consider the possibility of creating a temporary shelter for vegetables. Vegetable growers consider a dense mesh to be the best material for this purpose, it allows you to scatter direct sunlight, but at the same time does not create conditions for overheating of cucumber bushes.

The reasons why the leaves of cucumbers can turn yellow

The leaves on the cucumbers, still bright green yesterday, suddenly turned yellow. How dangerous is it for vegetables and what measures can be taken to save the harvest?

Yellow leaves

Vegetable growers name several main reasons for yellowing of leaves:

  • Lack of light. Cucumber bushes are so dense that the lower leaves of the lashes lying on the ground do not receive the required amount of sunlight. This reason is quite natural and there is no need to fight it.
  • High or low humidity. Cucumbers love water, but you can't create a swamp in the beds either. Increased humidity will result in root decay. A lack of moisture will cause the root system to dry out. As soon as there is not enough water for the roots, they will begin to climb to the surface of the soil, after which the leaves of the plant will immediately begin to turn yellow and the ovaries will fall off.
  • Infection of plants with fungal diseases. If drought and heat are replaced by a cold snap and lingering rains, the risk of infection of cucumbers with fungi increases dramatically.
  • Damage to the plant by pests. In this case, yellowing of the leaf occurs immediately after the appearance of small whitish spots on it. This is a spider mite and whitefly larvae suck juices from cucumbers.
  • Lack of nutrients. Lack of iron, copper, potassium, manganese, magnesium can cause wilting and yellowing of the leaves. If you don't take action, the whole plant will dry out.
  • Night frosts. After a sharp cold snap, the edges of the leaves freeze over, turn yellow, curl up and dry out.
  • Mechanical damage to the root system. Such a problem can arise if a support for a cucumber lash is digged into the ground next to the central stem. To prevent this from happening, you need to install the support posts before planting the seedlings in the ground.
  • Burnout in direct sunlight.
  • Natural aging of the plant. It occurs towards the end of the fruiting period, the cucumber whip begins to wither and dry.

How can you treat cucumber leaves from yellowing

If the cucumbers are affected by an infectious disease, they must be sprayed with any biologically active drug (for example, trichodermine). You can buy such a tool in a specialized store.

Water solution

To save plants beginning to get sick, the stem is smeared with an aqueous solution of iodine (1: 2) from the root to the ovaries. Spray the entire bush with flowers and ovaries with a mixture of brilliant green and iodine. To do this, 10-15 ml of antiseptics are dissolved in one bucket of water.

Council.A soda solution will help well against rotting and fungi. With this tool, you need to process the entire plant as a whole. For its preparation, 60 g of baking soda are diluted in 10 liters of water.

In addition to biological and chemical preparations, you can use folk methods aimed at improving the state of the garden culture. For a start, try sprinkling the cucumber beds with a serum solution. For one bucket of water, you need 2 liters of whey and half a glass of sugar.

To get rid of pests, use onion or garlic infusion. One one and a half liter can of dry onion peel is enough to prepare 10 liters of concentrated infusion. The infusion should be done like this:

  • the husk is poured with a bucket of boiling water;
  • insist all night until morning;
  • filter the broth;
  • the resulting drug is diluted (for 2 liters of infusion 1 bucket of water).

With this tool, you need to spray the plants completely:

  • leaves;
  • stems;
  • ovary.

After processing cucumber lashes, you need to water the soil in the garden with the remains of the solution.

If yellowness has just begun to appear on the foliage, you can treat the bushes with a solution of light pink manganese. With this tool, you can spray the beds for prevention, without waiting for the plants to get sick.

You can increase the fruiting time of an aging bush with the help of dressings.

For this purpose, the aerial part of the plant can be sprinkled with herbal infusions:

  • dandelion,
  • nettles,
  • swans.

It is useful to water the cucumber bushes with infusion of chicken droppings or mullein.

Preventive measures

For this you need:

  • maintain the principles of crop rotation and plant cucumbers every year in a new place;
  • water the plants in a timely manner;
  • mulch the root soil and the aisle with a thick layer of hay or torn weeds;
  • regularly feed the plants with herbal infusions, ash and mineral fertilizers;
  • after the appearance of the first 3-4 leaves, treat the plants with any solutions with antiseptics.

Important! In order not to lose the harvest, it is better not to wait until the plants get sick, but to regularly carry out disease prevention. Therefore, you need to know exactly how to process the cucumbers so that the leaves do not turn yellow.

So that the cucumbers in the beds do not hurt or turn yellow, you can make an effective remedy at home for the preventive treatment of bushes. To prepare it you will need:

  • laundry soap - 20 gr.;
  • iodine - 30 drops;
  • milk - 1 l.;
  • water - 10 liters.

All components are mixed with water, after which the composition is ready for use. Now they need to spray the whips and foliage of the cucumber bushes.

Another way to protect the cucumber bush from diseases and increase the period of its fruiting:

  • 1 loaf of bread is soaked in a bucket of water;
  • bread is left to infuse in water for 12-14 hours;
  • before use, 1 bottle of brilliant green is poured into the composition;
  • the resulting mixture is diluted in a ratio of 1:10;
  • the solution is sprayed and poured over the cucumbers.

The procedure must be repeated once every 10-14 days.

Once a month, you can water the plants with a soda solution (1 tablespoon of the product per 10 liters of water). Soda solution is detrimental to pathogenic fungi.

Intensive watering in the greenhouse

If cucumbers grow in a greenhouse, after harvesting the remnants of fertile plants, it is necessary to treat all structural parts of the structure with antiseptic preparations. They need to be sprayed from a spray bottle with a mixture of iodine and brilliant green diluted in water or any other suitable preparation.Means for treating premises from pathogenic fungi and bacteria can be purchased in specialized stores.

How critical is it not to fight yellowness on cucumber leaves; how will it affect fruiting

It is clear that no special measures need to be taken if the yellowness of the leaves is caused by natural causes, such as:

  • lack of light;
  • aging of the bush;
  • sunburn.

The only thing that can be done in this case is to carry out leaf and root feeding of the bushes. If dry leaves appear due to heat and burning direct sunlight, shelters can be installed over the plants.

Note! All of these reasons do not require urgent intervention.

If a pest is found in the beds or it is found that the plants are infected with infectious diseases, urgent measures must be taken to save the crop.

If left to chance, all the plants in the garden will quickly become infected and die as a result. In the best case, the cucumbers will throw off the ovaries and the yield will fall below average.

There are a lot of ways of processing garden plants, each vegetable grower will have to choose on his own how to spray the cucumbers so that the leaves do not turn yellow and wither. Every year amateur gardeners try new methods, preparations and home remedies for open beds and home greenhouses.
