Big Bill, I am 99.9% sure that they have virus x after reading a lot of information and pics comparing. I know for fact it is not from cold damage or too much sun. They might look like that in July which made it more concerning to me having me jump on the bandwagon to knock this out early. It's only May and sun and warm weather has been more scarce, breaking records with colder temps. I've had them in that garden for two years and was treating them for slugs and fungus where the holes in them from slugs diminished but after researching I realize why the "fungus" problem didn't resolve. It's because it isn't a fungus problem. Over the past two seasons I've seen it travel from one hosta to the next that are in front of the porch. I need to pull them out before the disease travels to the hosta that are close by on the side of the porch.
So, I go back to my original question if someone could help me find the answer to (after reading so many articles I couldn't find a clear answer), after pulling up the diseased hosta, how soon can replant in that same garden?
