Cannas from Karchesky's
I'm looking for a little advice about cannas. I've bought some red dwarf cannas from a couple different sources that have turned out to be diseased. I have some president red cannas in the ground now that are currently showing signs of the virus. I was thinking of digging them up and getting some from Karchesky's because I read that they were a good source for healthy cannas. My 2 questions are: will the virus be transmitted through the soil if I put them in the same place as the ones I currently have growing? (after I dig up the diseased ones of course) and secondly, has anyone bought from Karchesky's and had problems with the virus? Any advice would be appreciated as I'm still new to cannas but have quickly fallen for them!
