Propagation Growth Differential on pothos
What's Happening
Pothos cuttings exhibit differential growth rates based on node origin due to auxin gradients and stored carbohydrate reserves. Tip cuttings contain established meristems with high auxin concentrations and aerial roots, enabling rapid transition to active growth. Middle-node cuttings must first establish new meristematic tissue and root systems before producing new vines, causing delayed apical dominance shift and slower visible growth.
How to Fix It
- 1
1. Select tip cuttings with 2-3 nodes and visible aerial roots
- 2
2. Place in bright indirect light (200-400 fc)
- 3
3. Root in water (change weekly) or directly in well-draining mix
- 4
4. Expect new vine growth within 2-4 weeks for tip cuttings vs 6-8 weeks for middle cuttings
- 5
5. Transplant when roots reach 2+ inches in length
How to Prevent It
Always propagate pothos from tip cuttings with visible aerial roots when rapid establishment is desired; use bright indirect light during rooting to support photosynthesis.
