From a plant's perspective, Monstera deliciosa is a climbing hemiepiphyte, meaning it naturally grows upward by attaching itself to trees or other structures in its tropical habitat. Without support, its stems may sprawl horizontally, leading to weaker growth and smaller leaves. A moss pole or trellis mimics the tree trunks it clings to in the wild, encouraging larger, fenestrated leaves and healthier aerial root development.
Moss poles provide an ideal surface for Monstera's aerial roots to attach and absorb moisture and nutrients, just as they would in nature. The damp moss replicates the humid environment of tropical forests, promoting stronger root systems and vertical growth. Additionally, the pole's texture allows the plant to anchor itself securely, reducing stress on the stems and preventing breakage.
To avoid shocking the plant, gently guide its stems toward the pole while they are still flexible. Use soft ties (like plant Velcro or twine) to loosely secure the stems without constricting growth. Over time, the Monstera's aerial roots will naturally cling to the moss. Keep the pole moist to encourage root attachment, and adjust ties as the plant grows.
Trellises offer a broader support structure, suitable for larger or bushier Monstera plants. Unlike moss poles, trellises don't provide moisture, but their open design allows for creative shaping and spreading of stems. A Monstera will use its aerial roots to grip the trellis, though you may need to train the vines manually by weaving them through the framework.
Place the support structure close to the plant's base when repotting to minimize root disturbance. For moss poles, mist regularly to maintain humidity. Rotate the pot occasionally to ensure even light exposure, but avoid repositioning the support once roots have attached. Prune any unruly stems to direct energy toward upward growth.
If your Monstera's stems droop or leaves grow smaller than usual, it may lack proper support. Aerial roots dangling aimlessly or stems bending under their own weight are also cues to adjust or upgrade the support system. Healthy, well-supported Monsteras will produce more splits (fenestrations) in their leaves over time.
