What visual symptom may indicate plant stress?

Wilting leaves are a common visual symptom indicating plant stress. When a plant is under stress, it often struggles to maintain adequate water balance, leading to wilting. This occurs because the plant is unable to uptake sufficient water from the soil, which can result from various factors including drought, root damage, or over-watering. The leaves may droop or appear limp, signaling to the observer that the plant is experiencing issues that may need to be addressed.

In contrast, healthy green leaves, a full bloom of flowers, and deep root systems typically indicate a plant that is thriving. Healthy leaves reflect sufficient water and nutrient absorption, while flowers suggest that the plant is in a good state for reproduction. Deep root systems generally contribute to the plant's stability and ability to access moisture and nutrients, further supporting its health. Therefore, when observing plants, wilting leaves serve as a clear red flag of potential distress, making them a critical symptom to watch for in plant care and management.
