Picking leaves and allowing vines to fall can cause numerous wounds on the plant. When this is done on a rainy day, the damage can be even more severe. On cloudy or rainy days, ventilation is poor, and the humidity inside the greenhouse remains high. The wounds caused by leaf picking and vine falling will result in a significant loss of plant sap, which leads to the depletion of essential nutrients. Additionally, during rainy weather, plants often have lower energy reserves, making them more vulnerable. If these wounds further drain the plant’s nutrients, it can negatively impact the growth of cucumbers and reduce their ability to resist diseases.
Moreover, the sap that oozes from the wounds creates a favorable environment for harmful bacteria to thrive. This increases the risk of disease outbreaks and can lead to more serious infections. As a result, it's best to avoid performing such tasks during wet or overcast conditions.
To minimize damage and maintain plant health, it's recommended to pick cucumbers and prune vines during sunny mornings when the air is drier and the plants are more resilient. This approach not only helps preserve the plant's nutrients but also reduces the chances of infection, ensuring healthier and more productive crops. By choosing the right time for these activities, growers can significantly improve the overall quality and yield of their cucumber plants.
