My Japanese anemones (september charmer) bloomed beautifully last fall (planted in late September- in central Marylanc). This spring they made a great comeback with beautiful foliage. About 2 weeks ago, the leaves of one of the plants started to turn and wither. Started on the leaves lowest to the ground. The plant looks about dead now, but has a new tiny green shoot coming up. There is no evidence of pests and I did spray with an organic herbicide. The "blight" is spreading to the other anenomes. Does anyone know if this is just part of the life cycle of this plant or am I dealing with a virus or something else?

No. It was after they began dying.

Did you mean organic pesticide?

yes, herbicide.

Well if you sprayed it with herbicide that won't have helped matters because herbicide is designed to kill plants.

"I did spray with an organic herbicide" - was that before the anemones started to die back?
