Is there any data on how long plant viruses can hang out in the soil? Last year, I grew some Gloriosa superba from a commercial vendor. The plants exhibited color break in the flowers and some oddly deformed foliage, so I threw them out at the end of the season. I now have some new plants I grew from seed that came from Silverhill, and I wonder about locating them along the same fence as the old ones. The questionable plants were in pots, but roots may have invaded the ground. Same deal with Cannas in a flowerbed. I ripped out some clearly virused Canna about five years ago and would now like to replace them with virus-free stock from Tony Avent. Should I pick a different location?
