Neal, I'll wait till next spring to replant in same area. Falstaff has been in that spot for only 1 year, so thankfully it didn't have a very large root ball. I'll be sure to recheck the area for any residual roots before planting another plant there. It was in my new bed that I put in last year.
Madame Alfred Carriere was in a very large pot, and thankfully was not planted in the ground. I don't want to take any chances with leaving an infected plant in my garden.
