Last fall Randy Oliver said he was conducting a trial of the major pollen subs and would have results by February, 2014. I've searched several times since then but haven't found a thing. Now I know my searching skills leave a LOT to be desired, so I'm wondering... did I just miss seeing the trial results or am I looking in the wrong places or have they not been announced yet? I'm gonna make my first stab at grafting and I want to use a pollen sub in my builder/finisher but can't decide which one. I thought his trial might throw a bit of light on the subject.
