If the leaves of any crop turn yellow, then this is not normal. Especially you need to understand why the leaves of cucumbers dry, what needs to be done to prevent them from drying out. This article will explain in detail the factors that affect the growth of a vegetable and how to care for them to avoid such problems.

Growing cucumber seedlings

Before planting seedlings in the soil, you need to germinate the seeds. This is usually done 3 weeks before disembarkation on a windowsill or balcony, while the weather is still cold outside.

One option is to germinate the seed in the soil in separate cups. Good sunlight, moderate temperatures and good watering are important here. If these conditions are violated, the seedlings will grow poorly after transplanting into the ground.

When the seedlings are planted in the garden, they must be provided with fertilizers and the necessary trace elements. Sometimes the harm is caused not only by their lack, but also by their excess. In the latter case, additional watering with warm water will correct the situation. In this case, watered not only in the evening and in the morning, but also during the day. But at the same time it is necessary to limit exposure to direct sunlight so that the leaves do not wrinkle.

Drying leaves of cucumbers

It is also worth providing additional watering in hot weather. However, care must be taken that there is not too much water. Its stagnation leads to root decay.

Note! If the cucumbers are grown in greenhouses, it is recommended to additionally increase the humidity.

Why do cucumbers wither

When growing cucumbers, you can sometimes encounter their yellowing and spoilage. This happens in different ways. Sometimes they turn slightly yellow, in other cases they can dry and curl. Although this causes concern for the gardener, this sign does not always mean that there are problems with growing seedlings.

The following reasons lead to the fact that the leaves of cucumbers turn yellow:

  • Insufficient watering. This happens in cases where the crop is irrigated too rarely. It is especially dangerous when it happens in July. And sometimes watering is carried out regularly, but the volume of water is insufficient. As a result, the plant suffers from dehydration. By the way, excessive watering is also undesirable. In this case, the roots will begin to rot from stagnant water.
  • Another common reason the leaves dry out is the lack of feeding. During the growing season, plants are in dire need of complex nitrogen fertilizers.
  • In some cases, with inaccurate watering, sunburn occurs on the leaves. This occurs when water droplets enter at a time when they are strongly warmed up by the sun's rays. To avoid this, it is recommended to water not during the day, but in the morning and evening.
  • The presence of dry or sluggish branches is a consequence of a disease, for example, fusarium.

Insufficient watering leads to yellowing of leaves

Cucumber leaves dry and curl also because:

  • Insufficient amount of applied nitrogen fertilizers. If the leaves have grown narrow and do not increase in breadth, then there is a high probability that, with high-quality feeding, the seedlings will become healthy.
  • Powdery mildew can affect the plant in mid-summer. The disease leads to the fact that the leaves turn white, dry and shrivel. To prevent this from happening, for the purpose of prevention, you need to spray them with a 1% solution of Bordeaux liquid. In addition, when growing cucumbers in a greenhouse or greenhouse, they need to be regularly ventilated.
  • One of the reasons leading to the drying out of the plant is the attack of pests. When grown on a windowsill, this is unlikely to happen, but in the open field it is quite possible. To check, it is recommended to inspect the back of the sheet. Spider mites or aphids are likely to be found. To eliminate insects, you need to spray the bushes with acaricides or insecticides.
  • Unfortunately, it sometimes happens that a virus infection can cause drying. In this case, the fight is useless. We'll have to dig up and destroy the affected plants so that the remaining crops in the garden are not affected. Usually the presence of viruses is determined by the exclusion method, in the event that other reasons did not come up.
  • Violation of the temperature regime: hypothermia and burns. The first can happen not only due to cold weather, but also if there is a cold glass or greenhouse wall nearby. A burn is usually associated with excess sunlight or the presence of overheated objects in the immediate vicinity of the leaf edge.
  • Sometimes the plant reacts to the humidity of the surrounding air. If the level is low, it will cause the leaves to curl into tubes. To fix this problem, you need to ensure not only proper watering, but also air humidification.

Why does a rose have dry leaves

Note! The most vulnerable are the lower leaves. When problems arise, the plant throws its strength on the most important parts - these are the branches at the top and the ovary. The lower ones are fed last. In such a situation, yellowing will not indicate disease or any shortcomings, but is a natural phenomenon.

Cotyledon leaves are usually not removed - they themselves dry out when the need for them disappears. This is normal if there is a lack of sunlight or insufficient watering. As a result, the plant sacrifices its less important parts - the lower branches.

For the full development of cucumbers, potassium, phosphorus and magnesium are required. If there are not enough of them, the plant redistributes them in order to use them most efficiently. To establish the process, you need to feed the plant.

Note! The lower branches are primarily infected with Fusarium. This is due to the fact that they are closer to the ground. If this happens, you need to cut off the affected leaves and burn.

If the yellowing of the tops is observed towards the end of the season, then this is a natural process indicating the imminent end of the plant's life cycle.

Cucumber seedlings wither in the greenhouse: what to do

First of all, you need to establish the reason why this happened:

  • First you should check the temperature regime. When cucumbers wither in the sun, overheating may be the reason. In some situations, hypothermia is possible in cold weather. Here you will need to correct the temperature regime, eliminating the cause.
  • You need to make sure of the quality and quantity of watering. If done correctly, the soil at a depth of 10 cm will be slightly damp. In some cases it makes sense to increase the air humidity.
  • If the roots are damaged, this can be another reason why the leaves of cucumbers dry out. To check this, you need to carefully examine them. If insects are found that undermine them, it is enough to spray.
  • To determine why cucumber leaves wither, you need to carefully examine them. Especially carefully you need to check their underside. If insects are found, it is enough to remove and destroy them, and then also spray.

Note! It is possible that the leaves of cucumbers dry out from powdery mildew, what to do in such cases? This often happens in places where it is damp and cold. Outdoors, the likelihood of infection increases with frequent changes in warm and cold weather. It looks like a white coating with water drops. Infection starts from the lower branches. For treatment, the damaged parts of the plant are removed, then sprayed with appropriate means.

If the tops of the head dry

If the leaves have lost the ability to evaporate moisture, then the cucumbers wither and die, what do they do in such cases? They will experience overheating resulting in yellowing of the crown. In this situation, it is recommended to reduce the influence of direct sunlight as much as possible and increase watering.

Another reason why the tops of cucumbers can dry out is associated with poor root performance. If the ground is overheated or overcooled, then the roots will not fully cope with the supply of water to the leaves. This can also occur with insufficient watering, in the case of an excessive concentration of fertilizers in the open field, and in the case of nematodes. In such cases, cucumbers disappear in the ground and wither, what should I do? Check every possible reason.

The appearance of yellowed leaves on cucumbers is a warning sign. You need to check the possible causes as soon as possible and correct the situation. If you are late, then the bushes can completely dry out, and then there can be no question of any harvest.
