Monstera Aerial Roots: Trim or Keep?

By Marcus Williams · September 26, 2026

What Are Aerial Roots?

Monstera deliciosa naturally grows as a climbing vine in tropical forests. Aerial roots emerge from the stem nodes and serve two purposes: anchoring the plant to trees and absorbing moisture from humid air. In a home environment, these roots often dangle without anything to grip.

Reasons to Keep Aerial Roots

Nutrient absorption: They can absorb moisture and nutrients when placed in soil or water.
Propagation potential: A stem cutting with an aerial root has a much higher success rate.
Natural climbing: If you provide a moss pole, aerial roots will attach and support larger leaves.

When to Trim Them

Trimming is fine when roots become:

Unruly and tangled in walkways
Brown, dried out, or rotting
Excessively long with no surface to grip

How to Trim Safely

Use clean, sharp scissors or pruning shears. Cut close to the stem but leave a small nub. Sterilize tools with rubbing alcohol between cuts to prevent disease transmission.

Redirecting Aerial Roots

Instead of cutting, try guiding roots into the potting soil. Once buried, they function as regular roots and provide extra stability and nutrient uptake. You can also tuck them behind a moss pole to encourage climbing.

Aerial Roots in Water

Placing aerial roots in a jar of water can boost humidity around the plant. Change water weekly to prevent stagnation. This mimics the humid tropical environment Monsteras prefer.
