What does good drainage accomplish in plant care?

Good drainage in plant care is crucial because it prevents water accumulation around the roots. When water accumulates in the soil, it creates a saturated environment that can lead to various issues, including root rot. Healthy roots require oxygen, and excessive water limits the amount of air available to the roots, causing them to suffocate and potentially die.

Adequate drainage allows excess water to escape, which helps maintain an optimal balance of moisture and air in the soil. This balance fosters a healthy root system, enabling plants to absorb water and nutrients effectively. Without proper drainage, plants can suffer from numerous complications, including stunted growth or even death.

While other options mentioned might describe issues related to poor drainage or soil health, they do not directly address the core purpose of good drainage in plant care, which is to maintain a healthy root environment by preventing water accumulation.
