LE- The post showcases air layering, an ancient propagation technique where a plant stem is girdled, wrapped in moist moss, and sealed to form roots while still attached to the parent, as demonstrated in a 31-day time-lapse video of a purple-flowering shrub successfully rooting.
- Developed in China over 2,000 years ago for cloning ornamentals like ficus, the method boasts success rates of 90-95% with auxin hormones, outperforming cuttings by sustaining vascular connections, according to horticultural studies on species like Ficus benjamina.
- Beyond gardening, air layering principles inform space farming; NASA’s ISS experiments reveal plants in microgravity root via moisture cues rather than gravity, achieving viable propagation akin to Earth-based layering for sustainable off-world agriculture.
