What are the symptoms associated with root rot?

1. Bright green leaves

2. Stunting and small leaves

3. Rapid growth

4. Excessive flowering

The correct answer is: Stunting and small leaves

The symptoms associated with root rot primarily manifest through stunting and small leaves. Root rot is often caused by various pathogens that thrive in overly wet or poorly drained soil conditions, leading to reduced root function. When roots are damaged or decayed, they are less able to absorb water and nutrients effectively. This nutrient deficiency often results in smaller, underdeveloped leaves and overall stunted plant growth. In contrast, bright green leaves are typically a sign of healthy plants that are well-nourished, which would not be present in a plant suffering from root rot. Rapid growth is also indicative of a healthy plant, as the root system would be functioning properly to support this growth. Excessive flowering can sometimes occur in stressed plants, but it is generally not a direct symptom of root rot, which usually detracts from the plant's overall vitality and flowering ability. Thus, stunting and small leaves are the most accurate indicators of the adverse effects of root rot on a plant.
