Monstera plants have become a popular choice for indoor greenery, admired for their distinctive fenestrated leaves. As these tropical beauties mature, they often develop a unique feature: aerial roots. These roots, growing directly from the plant’s stems, frequently spark questions among plant owners about their purpose and how to manage them.
Understanding Monstera Aerial Roots
Monstera aerial roots are specialized structures that emerge above the soil line. These roots are a natural adaptation for Monstera plants, which are vining epiphytes in their native tropical rainforest environments. Aerial roots serve several functions that aid the plant’s survival.
One primary role is to provide structural support, helping the Monstera climb trees and other surfaces to reach more sunlight. They act as anchors, gripping onto surfaces to stabilize the plant. Beyond physical support, these roots can also absorb moisture and nutrients directly from the humid air and from organic debris. This dual function of support and absorption is a normal part of a Monstera’s development.
Should You Cut Monstera Aerial Roots?
A common question is whether these aerial roots should be trimmed. Generally, cutting them is not necessary for the plant’s health, as they perform beneficial functions. Some owners choose to cut them for aesthetic reasons, especially when they become long or get in the way. Others might trim them if they start attaching to walls or furniture.
If you decide to prune aerial roots, use sterilized, sharp shears for clean cuts and to prevent disease. It is safe to remove them, but do so sparingly and avoid cutting all aerial roots at once to avoid stressing the plant. Excessive cutting might reduce the plant’s capacity for supplemental moisture absorption and support. The plant will likely grow new aerial roots, making this an ongoing task.
Guiding and Utilizing Monstera Aerial Roots
Instead of cutting aerial roots, many choose to guide them for support. One effective method involves encouraging the roots to attach to a moss pole or trellis. This mimics the Monstera’s natural climbing habit, allowing it to grow vertically and often resulting in larger, more mature leaves. Misting the moss pole and the aerial roots can encourage them to adhere.
Another approach is gently directing the aerial roots into the potting mix. When these roots penetrate the soil, they can provide additional anchorage and absorb more nutrients and water. This method offers extra stability without an external support structure. Alternatively, allowing the aerial roots to grow freely is an option, especially if the plant has ample space and its appearance is not a concern.
Aerial Roots as Health Indicators
Monstera aerial roots can indicate the plant’s overall health and environmental conditions. Abundant or vigorous aerial root growth often indicates a healthy, thriving plant seeking more support or additional resources. It can also suggest adequate humidity levels.
Conversely, dry or brittle aerial roots may signal insufficient humidity. A consistent lack of aerial roots, especially in a maturing Monstera, could point to very low humidity or that the plant is still young. While aerial roots provide insights, they are one component of assessing plant well-being; observing the plant’s leaves and overall growth offers a more complete picture.
