Re: Black spots on stem and leaves?
I believe it to be bacterial. I think you have what mine did. I could not cure it and I even isolated a few miles away to see them grow and it was persistent. My neighbors finally would succumb to it. I think it is bad. I hope you get a better reply than me because I am also curious. My collection is so awesome I can't risk these companies messing thatup with contamination.
