Pothos (*Epipremnum aureum*) is a tropical vine that naturally climbs trees and other structures in its native habitat. From the plant's perspective, climbing is a survival strategy to reach brighter light, avoid competition on the forest floor, and maximize photosynthesis. Its aerial roots, which emerge from nodes along the stem, are designed to latch onto rough surfaces like bark or moss. When trained to climb a moss pole, these roots mimic their natural behavior, anchoring the plant and allowing it to grow taller and healthier.
For a pothos, a moss pole isn't just a support—it's a lifeline. The plant prefers a moist, textured surface that resembles tree bark. A sphagnum moss pole is ideal because it retains moisture, encouraging aerial roots to penetrate and absorb nutrients. From the plant's viewpoint, a dry or smooth pole (like bamboo or metal) is less appealing because it doesn't stimulate root attachment. The pole's height should also accommodate the pothos' rapid growth, ideally 2–3 feet taller than its current length.
Before introducing the moss pole, the pothos needs to be in the right condition. Younger, flexible stems are easier to train than older, woody ones. From the plant's perspective, abrupt bending or damage to stems can stress it, so gentle handling is key. Trim excessively long or leggy vines to encourage bushier growth near the base, which helps distribute energy for upward climbing. Ensure the plant is well-watered and healthy—stressed pothos may resist training.
To the pothos, the moss pole is a new environment to explore. Start by positioning the pole close to the plant's base in the pot. Gently wrap the vines around the pole, using soft plant ties or clips to hold them in place temporarily. Avoid tight bindings that could cut into the stems. From the plant's perspective, this mimics the way it would naturally encounter a tree trunk. Over time, the aerial roots will seek out the moss and attach on their own, allowing you to remove the ties.
For the pothos, a dry moss pole is like a barren tree—it won't encourage root attachment. Keep the pole consistently moist by misting it regularly or watering it directly. The plant will respond by sending aerial roots into the damp moss, securing itself. Rotate the pot occasionally to ensure even light exposure, but avoid frequent repositioning, as the pothos prefers stability once it starts climbing. Fertilize lightly during the growing season to support vigorous vertical growth.
If the pothos resists climbing, it may be due to low humidity, insufficient light, or a dry moss pole. From the plant's perspective, these conditions signal that climbing isn't worth the energy. Increase humidity by misting or using a humidifier, and ensure bright, indirect light. If aerial roots aren't attaching, try wrapping the stems closer to the pole or using a moisture-retentive moss blend. Patience is key—the pothos will climb when it feels ready.
As the pothos grows taller, it may outgrow its moss pole. From the plant's perspective, this is a sign of success! Extend the pole by adding a new section or transitioning to a taller support. Prune back any vines that stray from the pole to redirect energy upward. Over time, the pothos will develop larger leaves and a more robust structure, resembling its natural form in the wild.
