Philodendron: aerial roots
Quick answer
Aerial roots on Philodendron are natural adaptations for their epiphytic growth habit in tropical forests. These roots emerge from stem nodes and serve multiple functions: anchoring the climbing vine to tree bark, absorbing moisture and nutrients from humid air and rain, and supplementing soil root uptake during high growth periods. Scientific research (PMID 36786325) demonstrates that aerial roots actually outperform soil roots in nitrogen uptake regardless of source. Suppressing or removing aerial roots stresses the plant and limits its growth potential.
Start here:
- 1. 1. Direct aerial roots toward moss pole or support structure using soft plant ties
- 2. 2. Keep moss pole consistently moist—roots will attach and draw moisture from it

Other documented causes on philodendron:
- • Aerial roots serve as anchor points and supplemental absorption organs for climbing philodendrons. These adventitious roots emerge from nodes to attach to tree bark in native habitats, absorbing humidity and nutrients from tropical air and canopy debris.
How to handle aerial roots on Philodendron
- 1
1. Direct aerial roots toward moss pole or support structure using soft plant ties
- 2
2. Keep moss pole consistently moist—roots will attach and draw moisture from it
- 3
3. If aerial roots become unruly, gently guide them back toward soil or support
- 4
4. For propagation: aerial roots can be air-layered or rooted in water/soil to create new plants
- 5
5. If roots dry out and turn brown, trim dead portions but preserve living tissue
- 6
6. Apply diluted fertilizer to moss pole monthly during growing season to feed aerial roots
Ongoing Philodendron notes
Embrace aerial roots as healthy signs of vigorous growth. Provide climbing support (moss pole, coco coir pole, or wooden plank) for roots to attach. Maintain 60-80% humidity to support aerial root function. Mist aerial roots weekly or provide high ambient humidity. Never cut healthy aerial roots unless propagating.
