Leslie....I envy you with all that nice room and high shade. When I buy one now I either have to squeeze it in or dig out a little more lawn. You have a lovely garden. There are those here that are more familiar with the virus. My limited understanding is that it is transfered through the plants juices. If you cut through the roots or other part of the plant with a tool and then use the same tool on another plant you may transfer it. I would not spend a lot of time worrying....I have a number I have purchased from various sources and never had a problem.
