I have 4 mixed in with 30 other non grafted plants (I may have over done it on the plantings this year). So far only two plants have suffered due to the damp weather and it isn't the grafted ones. It also isn't the heirlooms which is odd because in the past they were always the first to suffer. So far there hasn't been any stand outs from the mix - good or bad. Now that the sun is shining again I'll be looking to see who performs best flavor and disease resistance wise.
