I would have loved to be part of that lesson of grafting/budding, but I probably did not even know what grafting/budding was at the time.  My very limited grafting experience is on apples, as my few citrus rootstock seedlings are not quite ready for grafting.  Or maybe I am not quite confident enough in my abilities yet to risk them!  Either way, budwood would then become my problem.  Maybe I will take the leap if the two grafts that I made on my apples this weekend take.  
Do the BC-1 and BC-2 go by a common name?  Satsuma is my next tree, hopefully this spring.  If they do have a tag name that I can look out for, I would love to know it.
