Monstera adansonii, often called the Swiss Cheese Vine due to the distinctive holes in its leaves, is a popular houseplant that is frequently seen cascading from hanging baskets. The answer is definitively yes: this species is a natural climber. It is classified as a hemiepiphyte, meaning it typically starts life rooted in the ground before seeking vertical support.
The Natural Climbing Mechanism
The ability of M. adansonii to ascend vertical structures is facilitated by specialized aerial roots that develop along the vine’s nodes. These roots serve two distinct purposes.
Anchoring Roots
Some roots are thicker and relatively short, acting solely as anchoring mechanisms to physically adhere the plant to a support surface. These roots exude a sticky substance that helps them grip bark or other rough textures securely.
Absorptive Roots
Other aerial roots are longer and thinner, designed to hang freely or penetrate the moist substrate of the support. These roots are responsible for taking in atmospheric moisture and dissolved nutrients. Climbing allows the plant to quickly move out of the dark understory. By scaling large host trees, the vine gains access to the canopy’s bright sunlight, which is necessary for robust photosynthesis.
Trailing Growth Versus Vertical Maturity
When a young Monstera adansonii lacks a stable, vertical structure to attach to, it defaults to a trailing or creeping habit. This is an opportunistic growth pattern, but it prevents the vine from achieving its full biological potential.
Providing a stable, vertical support initiates ontogenetic change, the shift from juvenile to mature growth. Once the plant’s anchoring roots secure themselves, subsequent leaves dramatically increase in size. This change is linked to the plant sensing the stable vertical light source above it.
Vertically supported vines exhibit far more pronounced fenestration, or hole formation. These larger leaves are more efficient at capturing light, which is the primary reason the plant invests energy to climb. Trailing vines maintain smaller, less fenestrated leaves because the plant does not expend energy on large leaf production without the promise of better light.
Essential Support Structures
Owners must provide a specialized support system. Simple bamboo stakes or thin metal trellises are not the most effective options for encouraging robust growth. The most beneficial structures mimic the rough, moisture-retaining bark of a host tree.
Moss poles are highly recommended because they retain water exceptionally well. This sustained moisture encourages the plant’s absorptive aerial roots to penetrate the pole itself, establishing a stronger connection. Cedar planks or bark-covered posts also serve as excellent, textured surfaces for the roots to adhere to.
Training the vine involves gently guiding the main stems against the pole and securing them until the aerial roots naturally take hold. Use soft materials like plant ties, garden twine, or velcro strips to hold the stem flush against the support structure. As the plant grows, continue to secure the newest sections every few weeks, ensuring that the nodes remain in contact with the moist pole to maximize root attachment and stimulate mature growth.
