Carter,the jury is still out on brugs.I tried two varieties ,one with known virus and one just to see if the cuttings were harmed.None were harmed by 120 degree heat and the one with virus(4 cuttings) appears to be fine now.The problem with the brugs is that I have religiously culled varieties with virus so do not have much to work with.I do have two more varieties I will be trying this week but those are the last two with signs of virus so that will end the brug experiments for now.
