You do need 2 trees that are not genetically identical, or at least that is my understanding. The tree sends out runners. I have cut them and put them in water. If they root, you're welcome to them. I bought mine 10 years ago at Cedar Rim Nursery... but that was 10 years ago. I later found some at random in a Nursery on #6 Road in Richmond. I couldn't help myself and bought 3 there, which I gave away to an acquaintence who runs a Blueberry farm in Maple Ridge. All this to say, I can't really be of much help, unless I can get those runners to root. Stay tuned!
