I've read through this thread and what I can tell you is this. In our nursery we've tried everything known to man to root cuttings. People give me samples of gels, powders, spray over applications, everything. The one thing that always, always gets the best results on every plant we do is good'ol dip and grow, in a 10-1 solution. We root rubrums, elms, hydrangea, franklinia, cotinus, everything with 10-1. We stick them in straight pumice and put them under floramist nozzles attached to a mistamatic. We root over a million cuttings this way every year.

Mike Dir was at the Farwest Show in Portland last weekend and he wanted to know what "witches brew" we used to get such high takes on our Royal Purple, and Golden Spirit Smoketree. He was floored when I told him 10 to 1 Dip n' Grow. It's not rocket science and you can make it far more complicated then it has to be. And as far as hydrangea, Snow queen and Passionate (New Tardiva) root almost 100%. We do trials on every new product there is and we still make our living on dip n' grow. Keep it simple.
