Growing Brugmansia in Zone 4B
I am moving to Mitchell, South Dakota (Zone4B) from Louisville, Kentucky. How do you get them to bloom all summer? Even here in Zone 6B, they wait until late September/October and just when they are at the peak of bloom, they get hit by frost. The plants look great and I keep them in full sun, but I am doing something wrong. I have no trouble keeping them in the basement all winter.
