The above propagation data sourced from Claude AI

Pre-treatment: Cuttings sorted for uniformity, lower leaves stripped, stems wounded with a 1 cm side scrape, and dipped 15 mm deep in 2000 ppm IBA and 1000 ppm NAA as Dip-n-Grow in 25% ethanol for 5 seconds with no shake.

Establishment: Cuttings were collected early in the morning from field-grown plants. The Nearing frame plants were healthier in appearance.
