Drying and turning yellow cucumbers in the greenhouse: why the leaves wither, what to do if dry little cucumbers

If cucumbers wither in the greenhouse, then perhaps they do not fit the primer Yellow, and even the drying cucumbers in the greenhouse is not uncommon. Many gardeners this phenomenon is associated with arid summer, or vice versa, excessive rain. They also sow on infected seeds, on diseases, and on pests. Much of this can be the true cause of yellowing. But more often the case in violation of agricultural technology.

Technology: why cucumbers wither in the greenhouse

All cucumbers love moisture very much. And the main investment in their growth and development is proper watering. Cold water is not used, water should be infused and lukewarm. As soon as the cucumbers began to bear fruit, the irrigations become more frequent. To focus on watering costs, because it is important in many ways. For example, it is very important that the roots of cucumbers grow in depth, and not outside.

Cucumbers in the greenhouse can dry up due to non-compliance with the temperature conditions.

It is worthwhile to water a couple of times as you notice the yellowing of the plant, and the new ovary will also turn yellow. Cucumbers quickly signal a lack of water.

And if the ovaries are not only yellowed, but also dry already, immediately remove the faded flowers, applying a cut on the potassium permanganate. Do not forget about the feeding. Vodicka cucumbers drink, this is their main need, but they also need feeding. It is not often, according to the schedule, and it is quite possible to do organic.

Powdery mildew: cucumbers dry in the greenhouse

If both small and large leaves dry out, the plant may have been affected by powdery mildew, a notable enemy of cucumbers. In this case the plant leaves are covered with bright, enlarged spots. This indicates the defeat of cucumbers, the leaves will dry and turn yellow.

To cope with this scourge, resort to the help of fungicides. Other methods are less effective, and most often you need to act quickly and decisively.

Fusariosis can also be the cause of withering of cucumbers:

• This is a fungus that most often "attacks" cucumbers in the greenhouse;
• Infection will have to change the whole soil, half measures will not help;
• You can initially acquire those varieties of cucumbers that are resistant to fusariosis and powdery mildew.

So that cucumbers do not dry out, they should be regularly fertilized and watered

Which pests to fear?The most important enemy of cucumber is aphids. She settles on the underside of the leaf and literally drains from the cucumber all the juices. Steals all the nutrients, causing the plant to wither. Tlou need to be destroyed, sometimes it is enough to bring into the greenhouse ladybirds, but if the matter is acute, then you will have to buy a special chemical.

What else can be: Why do yellow and dry cucumbers in the greenhouse

But it is often a sin to complain about pests and diseases. Just violated a certain regime, which should be in the greenhouse constant. They are sinning with these young summer residents, who are armed with chemistry against a potential enemy, but it is forgotten to ventilate the greenhouse, or do not take into account the humidity norms that should be in the greenhouse.

Cucumbers can dry and yellow for the following reasons:

• Even when seedlings are planted in the greenhouse, the temperature of the soil must be the same, everything is measured and controlled. The soil should warm up to 16-18 degrees. Possible artificial heating.
• The soil in the greenhouse can be depleted. If you did not conduct preparatory work in the fall, do not be surprised at a meager or poor harvest. Soil must be rich, nutritious, ready for fertility. This means that you do not just need to remove the top layer and dig everything, you also need to feed the soil.
• Again watering - look at the greenhouse moisture. The hotter in the greenhouse, the higher the humidity. Water the cucumbers in the morning or in the evening, at the height of the day, do not do it.

Cucumbers in the greenhouse can dry due to various pests and diseases

Perhaps you are not airing the cucumber zone. You forget to open the greenhouse in time, which, incidentally, can interfere with the natural processes of pollination, because the bees do not get into the greenhouse in any way.

Thick planting is another common problem for beginners. Between the whips there will be so little air that it will be difficult to grow cucumbers. Observe the required distance, do not try to plant 1 m 5 seedlings and more.

Prevention: not to dry and pickled cucumbers

If you see that the leaves of cucumbers turn pale and strive to spin from below, they most likely lack nitrogen. Nitrogen deficiency, of course, need to be filled. Examine the leaves - if they were stretched along, and the leaf plate did not grow, just as the soil needs high-quality complex top dressing.

Cucumbers are also sensitive to burns and hypothermia. Hence, the temperature regime should be optimal. If the glasshouse is glass, the leaves should never come into contact with either hot glass or cold glass. Cold watering and spraying can also do harm.

So that the cucumbers in the greenhouse do not yell, it should be periodically ventilated

And if the yellow leaves are yellowing, it means that it is difficult because of the thick foliage on top, they do not reach neither light nor water. Most importantly, the sun can not get to the leaves, and this is a necessary condition for growth. Again, you have to remind you about the optimum density of planting.
