Can I propagate a 3 inch in diameter branch/trunk from an existing Jacaranda tree in our yard? (Its smashed between the Torrey Pine and Pomogranate, another reason I want to use part of the tree if possible because we probably need to take it out.) FYI, the part of the tree I want to propagate is not green wood. My goal in all this is to have the start of a tall Jacaranda tree without having to buy and haul a mature tree into our yard. Would it be as simple as using rooting powder? Could I graft it? Sorry, I'm new to the Frankenstein methods of grafting and propagating. Any advice would be great! Thanks
