What is the recommended treatment for cankers in plants?

The recommended treatment for cankers in plants involves pruning out the affected areas and applying fungicide. Cankers are typically caused by fungal infections, which can create dead or dying tissue on the plant. By carefully pruning out the cankerous portions, you remove the infected material, which helps to prevent the spread of the disease to other areas of the plant or to neighboring plants.

Following up with a fungicide application is crucial in this process because it helps to protect the remaining healthy tissue from future fungal infections. The fungicide can inhibit the growth of any potential pathogens that might still be present in the environment or on the plant.

Other treatment options, such as soil amendments, liquid fertilizers, or special nutrient watering, may help improve overall plant health but do not address the immediate issue of the canker itself. They could potentially provide a more favorable environment for the plant, but without directly managing the infection, the plant’s chances of recovery would be significantly hindered. Thus, the combination of pruning and fungicide application is the most effective approach to treating cankers.
