What is one of the consequences of improper mulching?

Improper mulching can lead to root suffocation, which occurs when mulch is applied too thickly or directly against the trunk of a tree or shrub. This excessive mulch can create an anaerobic environment, limiting the amount of oxygen that reaches the roots. Roots require oxygen for respiration; without it, they can become stressed and may eventually die. Additionally, improper mulching can trap moisture around the base of the plant, potentially leading to issues such as root rot and other fungal infections due to excess moisture and poor air circulation.

In contrast, while enhanced soil quality, improved moisture retention, and suppression of weeds are benefits of proper mulching practices, they can be negated if mulching is not done correctly. Therefore, understanding the proper application of mulch is critical to promoting healthy plant growth and preventing detrimental outcomes such as root suffocation.
