I air-layered some 5 trees and separated them from the mother trees and they are in pots doing very well I give just one hour a day of sun until the root get established. I have no luck with cuttings and bagging. With air-layered I used root hormone powder and the roots are grown very healthy and long. My question is if I give the 1-3 years old tree some root hormone does it help the root I am very curious. Does any body know of any research done on that. I have 2 year old Chicago hardy (no fruiting yet) I gave her very little root hormone I want to see what will happen.
