Blueberry Propagation

I have looked on the internet with no luck.

Does anyone know how to propagate a blueberry bush?
I have tried doing it like marijuana cuttings about 20 and they all died

maybe try air layering, i read they can be a pain and take awhile

Nick the side of a lower branch and bury that piece while still connected to the main plant. Usually roots will sprout out of the side where you nicked it and it can be removed from the main plant. Takes a long time, but has a really high success rate with most hard to root plants.
