What is a common symptom of plant diseases?

A common symptom of plant diseases is indeed the presence of abnormal growths such as lumps. These abnormal growths, which can manifest as galls,swelling, or tumors on plant tissues, often arise due to pathogenic organisms like bacteria, fungi, or viruses affecting the plant. These pathogens can disrupt normal cellular development and growth patterns, leading to these irregular formations.

Healthy leaf growth, increased flower production, and bigger fruit size are typically indicators of a plant's good health and can be part of the normal growth process. However, when a plant is diseased, these positive growth indicators are usually diminished or affected negatively, making the presence of abnormal growths a significant symptom of underlying issues. Recognizing these abnormal growths enables gardeners and farmers to identify and respond to plant health issues promptly.
