What should you do if you suspect a plant has a disease?

If you suspect a plant has a disease, isolating the plant and diagnosing the problem before treatment is the most effective approach. This step is rooted in the understanding that diseases can spread to other plants, especially if they are left in proximity. By isolating the affected plant, you prevent potential contagion to healthy plants in the vicinity.

After isolation, diagnosing the problem enables you to identify whether the issue stems from a fungus, bacteria, virus, or environmental stress. This knowledge is crucial for determining the appropriate course of action for treatment, whether it involves fungicides, bactericides, or adjusting care practices such as watering and light exposure. Taking the time to properly assess the issue aids in addressing it effectively and can prevent further complications or loss of additional plants.

In contrast, watering more or ignoring the situation does not address the underlying problem and may exacerbate the issue. Moving the plant outside for fresh air might be beneficial in some cases, but without first isolating and diagnosing the problem, you risk spreading the disease further or leaving the plant exposed to additional stressors. Therefore, isolating and diagnosing are critical first steps in managing any suspected plant disease.
