Cucumbers grow almost all gardeners, both experienced and beginners. The technology of growing this crop is known to everyone, but nevertheless, in many areas every season there is a problem - the leaves of the cucumbers wither. Let's try to figure out why this is happening.
The first and most common reason why cucumber leaves wither is a banal lack of moisture. If the plant does not have enough water, its leaves will first wither, fade, and then begin to dry from the edges to the center. How to determine what the reason is the lack of water? Very simple - start to moisten the beds every day, morning and evening, and if the situation quickly changes for the better, then the problem was only in the wrong watering regime.
The second reason why the leaves fade in cucumbers is directly related to the first. If you planted tomatoes and cucumbers in the same greenhouse, such a neighborhood will not lead to anything good. Despite the fact that both plants are thermophilic, cucumbers require high humidity, which tomatoes can not stand at all. That is why it may turn out that, trying to please the tomatoes, you “overdried” the cucumbers, and again they suffer from a lack of water.
The third reason why the leaves are withered in cucumbers is to get herbicides on the bed. Cucumbers can not stand them at all, so you should not use chemicals not only in the greenhouse, but also in neighboring beds. If the herbicides have already managed to get to the plants, then plentiful watering will help - the chemicals will simply wash off with water and go further into the soil.
Another reason why leaves fade in cucumbers is the defeat of aphids. Confirm or refute it is very simple - you need to look at the back of the sheet. If you find aphids there, then you need to take urgent measures, since the pest can infect all healthy plants in a matter of days. It is best to use a soap solution or special chemicals, such as Iskra or other similar drugs. In addition, cucumbers can suffer from a fungal disease or from ticks. They get rid of the first with the help of chemicals like "Fotosporin", and the second - with the use of onion husk infusion.
The last reason why leaves fade in cucumbers is due to improper agricultural technology, that is, a whole range of factors that affect the plant to one degree or another. For example, an excess or lack of fertilizers, an improperly chosen place for planting, when direct sunlight actually burns the leaves. Incorrect irrigation technology can be included here, when plants are watered frequently, but little by little. As a result, water does not get to the roots, and the plant begins to suffer. Another mistake when watering is spraying water directly on the leaves on a bright sunny day. Water droplets turn into tiny lenses and cucumbers get burned.
So, we enlightened you on the question of why cucumbers leaves wither, and we indicated the most effective methods of dealing with this phenomenon. Take care of your plants and they will delight you with a delicious and rich harvest.
