What is the problem with yellow cucumber leaves? How to solve the problem of yellow cucumber leaves

Cucumber is a common vegetable in life. Because it has the effect of improving human metabolism, many families grow it. However, when growing cucumbers, the leaves of many cucumbers turn yellow. Here, the editor will share with you some tips on growing cucumbers, hoping it will be helpful to you.

What is the disease of yellowing cucumber leaves?

Yellowing of cucumber leaves may be caused by gray mold, which will corrode the leaves of cucumbers, starting with yellowing and eventually causing the leaves to wither and rot. It will also infect the cucumber fruits. If not treated in time, it will die. At this time, it is best to control the temperature of the cucumbers to around 20 degrees Celsius, and it is best to spray them with pesticides every ten days or so, such as cypermethrin wettable powder.

It may also be powdery mildew. If the cucumber gets powdery mildew, small round mold spots will appear on the leaves, which are white and powdery in shape. Slowly, the cucumber leaves will turn yellow, and the range of yellowing will gradually expand. At this time, we must cut off the leaves that have powdery mildew, and then keep the cucumber in a ventilated place, and spray it with medicine to treat powdery mildew once every seven days.

How to solve the problem of yellowing cucumber leaves

1. Cucumber is a plant that likes water, but if you water it blindly, it will cause water accumulation, which will cause the leaves to turn yellow. When we find that the leaves at the top of the cucumber turn yellow, it proves that there may be too much water. Therefore, when watering the cucumber, you can water it frequently, but water it in small amounts each time. Too much water will not only affect the growth of cucumbers, but also make it easy for diseases and pests to occur.

2. If cucumbers want to grow well, they need balanced nutrition. But many times we ignore this when fertilizing cucumbers, and the lack of nutrients will cause the cucumber leaves to turn yellow. Therefore, when fertilizing cucumbers, we should pay attention to providing them with comprehensive nutrients and fertilize according to the specific growth conditions of cucumbers, so that cucumbers can grow better.

3. When cucumbers are infected with pests and diseases, their leaves will turn yellow and even affect the growth of cucumbers. Therefore, when caring for cucumbers, you should pay attention to pest and disease prevention. If pests and diseases have already appeared, you need to spray them with fungicides in time. After spraying several times, the situation will be significantly improved.

Tips for high cucumber yields

When we plant cucumbers, we need to select base fertilizer, and then pay attention to watering and temperature. Because cucumbers are warm-season vegetables, the temperature must be below 32 degrees when breeding. Moreover, many farmers now control the temperature at 35 degrees Celsius during breeding, and some will control it at around 40 degrees.

Of course, when we grow cucumbers, we will also encounter problems with diseases and pests, so we also need to spend time treating diseases and pests, but it is best not to use drugs for treatment, and we must also apply fertilizers scientifically. In fact, cucumbers need to apply corresponding fertilizers at each growth stage, and the amount of fertilizer must be controlled. In this way, the cucumbers will be resistant to diseases and will not be prone to diseases and pests.

The roots of cucumbers absorb nutrients from the soil. Generally, during the growth period of root cucumbers, top dressing is needed 2-3 times a month. Just make sure the plants do not become dehydrated.
