Monstera aerial roots, a natural feature of the Monstera deliciosa plant, are adventitious roots that emerge from the stem. These roots differ from typical soil-bound roots in that they seek moisture and support from the air and surrounding environment. For example, a long, thick root extending from a node on the stem is an aerial root.
The presence of these roots signifies a healthy and mature plant, indicating its natural inclination to climb and seek nutrients. Historically, in their native tropical environments, these roots allow the plant to attach to trees, providing stability and access to higher light levels. Further, they contribute to nutrient absorption from humidity in the air.
