We lived in Columbia for most of our adult life. Now we are down in the southeastern corner on a marshy island.
I just looked in several propagation books:
The Reference Manual of Woody Plant Propagation by Michael Dirr, Ph.D and Charles Heuser, Jr. Ph.D.
Growing & Propagating Showy Native Woody Plants by Richard E. Bir
Creative Propagation Second Edition by Peter Thompson, Ph.D.
None of these even address air layering. Guess it is too labor intensive for commercial purposes.
