Overwatering plants often manifests through leaf drop and yellowing, which are significant indicators of stress resulting from excess moisture in the soil. When plants receive too much water, their roots can become waterlogged, leading to oxygen deprivation. This condition hinders the plant's ability to absorb nutrients effectively, thereby causing yellowing of the leaves—a process known as chlorosis. As the roots begin to deteriorate due to poor aeration and potential root rot, the plant may also respond by shedding leaves to conserve resources, further displaying leaf drop.

In contrast, bright green leaves can suggest that a plant is healthy and receiving sufficient water and nutrients. Quick growth of new stems typically indicates a favorable growth environment with proper hydration but is not a direct sign of overwatering. Strong root development usually occurs when conditions are optimal, allowing for adequate drainage and aeration, which is the opposite of what happens when a plant is overwatered.
