Interesting, John, I never think about such things. Good information to have. As an FYI, I snapped the stems off by hand. I wonder what commercial growers do about such virus? I have to admit that I rarely fuss over such things since I am not a serious grower or collector of the genus, they just do well for me for some reason, which keeps me curious about them. For two years now I almost moved them to the compost pile to make room for other genera, then, this year, they almost all bloomed, (clearly, they trying to send me a signal!)
