Air Layering: An Old Practice with a New System for Tropical Fruits and Native Plant Preservation. - 2019

by Dr. Joe DeFrank with Kalani  Matsumura as on site host.

  Dr. Joe DeFrank made a requested presentation at the Pearl City Urban Garden to a group of interested home owners on 05/10/2019.  He discussed a new device for air layering tropical fruit trees and native Hawaiian plants located in remote mountain locations.  This new air layer device allows for rooting branches and root suckers of various stem sizes.  Dr. DeFrank suggested using air layered branches of mature woody fruit trees to exchange pollen for international breeding programs.  Air layering root suckers of elite native Hawaiian Koa and ROD-resistant Ohia was discussed for use in developing seed nurseries in more easily accessible  locations.  Following the lecture/slide show, participants were shown how to fill plastic netting with rooting media as well as how to strip bark and the cambium layer in preparation for the application of the sphagnum filled net sacks to a Logan tree.
