Training a Monstera to climb a moss pole is an effective way to replicate the plant’s natural growth structure in a home environment. In their native tropical habitat, these plants grow up the trunks of trees, and a moss pole serves as an ideal substitute. Providing a vertical surface encourages healthier, more vigorous growth and helps the plant achieve the large, characteristic leaves that make it so popular. This guide details the process, from understanding the plant’s biology to the long-term maintenance of the pole itself.
Understanding the Monstera’s Growth Habit
The Monstera deliciosa is naturally a hemiepiphyte, meaning it begins life either in the ground before climbing a host tree, or in a tree before sending roots down to the soil. This climbing habit is linked to the plant’s maturity and the development of its iconic fenestrations (splits and holes in the leaves). Allowing the plant to climb generally produces larger leaves with more complex fenestrations, a process known as leaf maturity.
The plant uses specialized structures called aerial roots to anchor itself and climb upwards. These roots emerge from the stem’s nodes and provide structural support while absorbing moisture and micronutrients. When a moss pole is kept moist, it mimics the bark of a wet jungle tree, encouraging the aerial roots to penetrate the surface and securely fasten the plant.
Materials and Installation of the Support Pole
To begin the training process, you need a sturdy moss pole, typically constructed from a core wrapped in sphagnum moss or coco coir. Sphagnum moss is often preferred because it retains moisture more effectively than coco coir. You also need soft plant ties, such as Velcro, twine, or cotton string, to temporarily secure the plant to the pole.
Installation is best done during repotting to minimize root disturbance. Place the pole deep into the container, ensuring the base rests against the bottom for stability. Position the pole close to the main stem, ideally where aerial roots naturally emerge (usually the back of the plant). Fill the container with fresh potting mix around the root ball and the pole, ensuring the pole is securely anchored and upright.
Securing the Plant and Guiding Aerial Roots
Once the pole is installed, carefully align the Monstera’s main stem against the support structure. Use soft ties to gently secure the primary vertical stem to the pole at various points. It is important to tie the stem itself, which is the thick, central axis of the plant, and not the petioles (the stalks supporting the leaves). Securing the petioles restricts the leaf’s ability to move toward light and can damage the plant.
Position the stem so that existing aerial roots or the nodes from which they emerge are in direct contact with the moss pole’s surface. Guide longer, pliable aerial roots against the pole to encourage them to embed. The initial ties hold the plant until the aerial roots grow into the moss, providing a permanent anchor. As the plant grows taller, continue adding ties at each node to maintain vertical alignment.
Maintaining Moisture and Extending the Moss Pole
The success of the moss pole depends on maintaining consistent dampness within the material. A moist pole allows the aerial roots to penetrate the moss and absorb water and nutrients directly from the support. To prevent the pole from drying out too quickly, mist the surface regularly or use targeted slow watering from the top. Specialized watering systems, such as a self-watering spike or a drip cap inserted at the top of the pole, can keep the moss consistently damp without oversaturating the soil.
As the Monstera grows, it will eventually reach the top of the existing support structure, necessitating extension. Extend the pole before the newest node grows past the top edge. Many moss poles are designed to be stackable, allowing a new section to slide directly into or on top of the old one. Secure the two poles together using cable ties or sturdy ties to ensure the entire structure remains stable as the plant gains height and weight.
