Monstera plants, particularly Monstera deliciosa, are known for their striking foliage and unique aerial roots. These roots emerge from the stems and grow outward, often appearing thick and brown. From a plant's perspective, aerial roots serve critical functions: they provide structural support by anchoring the plant to trees or other surfaces in their natural habitat, absorb moisture and nutrients from the air, and facilitate climbing to reach sunlight in dense forests.
Aerial roots are not merely decorative; they are vital for the plant's survival and growth. In the wild, Monstera uses these roots to cling to trees, enabling it to grow taller and access brighter light. Indoors, where vertical support may be limited, aerial roots still contribute to the plant's health by absorbing humidity and even nutrients if they reach the soil. Cutting them unnecessarily can disrupt the plant's natural growth cycle and reduce its ability to thrive.
While it's generally best to leave aerial roots intact, there are exceptions. If a root is damaged, diseased, or rotting, removing it can prevent the spread of infection. Additionally, if the roots become excessively long or intrusive—for example, tangling with furniture or other plants—trimming them slightly may be practical. However, cutting should be minimal and done with sterilized tools to avoid stressing the plant.
Instead of cutting, consider redirecting aerial roots to better serve the plant. For example:
Removing healthy aerial roots can weaken the plant, especially if it relies on them for stability or hydration. Cutting too many roots may also trigger stress responses, such as slowed growth or leaf yellowing. In extreme cases, the plant may become more susceptible to pests or diseases due to reduced vitality. Always weigh the benefits against the risks before deciding to cut.
If trimming is unavoidable, follow these steps to minimize harm:
