How do drought-tolerant plants behave with additional water?

Drought-tolerant plants have adapted to survive in environments where water is scarce by developing specific physiological and morphological traits. These adaptations include deep root systems, reduced leaf area, and even the ability to store water within their tissues. When these plants receive additional water beyond their basic needs, it can disrupt their natural growth patterns and lead to various issues such as root rot, fungal diseases, or stress from over-saturation.

Therefore, they do not thrive with additional water because they are evolved to be efficient in utilizing minimal water resources. Excessive watering may lead to an environment that is too moist for these plants, potentially harming their health and overall growth. This behavior reflects their adaptation to arid climates, where conservation of water is crucial for survival.
