Anyone growing the new echinaceas? Any wilting problems? I bought several varieties......fatal attraction, tiki torch, sunrise, harvest moon etc,.... And all wilted. I decided to pot up and grow on and last year they wilted again. I cut the, down in mid summer, fed and watered them and they flourished. This year I am doing the same thing,viz., cutting back in mid summer, watering well, etc and they look ready to flower now. Anyone else with issues with echinaceas?
