Pothos: aerial roots training
Quick answer
Pothos aerial roots require stable attachment points to trigger hormonal changes that increase leaf size. When aerial roots anchor to vertical supports like moss poles, the plant receives a 'climbing cue' that signals maturity and triggers morphological changes. Nodes stabilized by aerial root attachment produce significantly larger leaves (up to 2-3x size) compared to unsupported trailing vines. This phenomenon, called 'heteroblasty,' is regulated by auxin distribution and mechanosensing in root tissues.
Start here:
- 1. Install moss pole or coir pole at least 18 inches tall in pot center
- 2. Secure stem segments with loose plant ties every 6-8 inches along pole

How to handle aerial roots training on Pothos
- 1
Install moss pole or coir pole at least 18 inches tall in pot center
- 2
Secure stem segments with loose plant ties every 6-8 inches along pole
- 3
Mist moss pole daily to encourage aerial root attachment to damp substrate
- 4
Wait 4-6 weeks for roots to naturally adhere before removing support ties
- 5
As plant climbs, extend pole or replace with taller support to continue progression
Ongoing Pothos notes
Begin training when vines reach 12-18 inches long; delay results in established trailing habits that resist vertical transition.
