Foliar applications of rooting hormone at Decker Nursery

摘要

Decker Nursery currently uses only over-spray methods to apply rooting hormones on softwood and dormant hardwood cuttings of woody ornamentals. We have been evolving down this path away from liquid dip and powder application methods for the last 4 years. In this presentation, I will attempt to review the history of this evolution, our current methods of application, a summary of our observations, and the current status of research on the over-spray method.
