I just happened to be browsing around a bit and popped in and saw this thread. Interesting about the Nematodes. I only have 3 Brugs, 2 in ground, 1 in a pot. The 2 in the ground do much better for me than the one in the pot as far as growth/bloom etc. I just let them freeze back in winter and regrow. The one in the pot has been pulled into cover during our freezes, but...no more. Too much work and I think it actually does them some good to freeze back and have that dormant period. At least here. I realize that's not possible farther north.
